What Is a Bund? Emptying and Overfilling Risks

Ever looked at a bund on site and thought, “Right, I know it must be important… but what actually is it?” 

You’re not alone.

Bunds are one of those things that often blend into the background until there’s a problem. A bit of rainwater builds up. A spill happens. The liquid level rises more than expected. Suddenly, the thing that was meant to contain a problem is creating one.

This guide breaks it all down simply: what a bund is, why it matters, the different types, how to empty them safely and how to avoid overfilled bunds in the first place.

What Is a Bund?

Other than a word that sounds less real the more you say it, a bund is a secondary containment system designed to catch liquid overflow if the main container leaks, spills or fails. It’s a protective area around or beneath a tank, drum, IBC, or similar container, there to stop oil or other polluting liquids escaping into the ground, drains, or the surrounding environment.

The Oil Storage Guidance in England and Wales requires secondary containment around your container, which is usually either:

  • a drip tray beneath the container
  • a bund: an outer case which holds the container

It also states that fixed tanks must be bunded, whilst other containers can be bunded or use drip trays.

The exact design varies, but the job stays the same – contain the liquid before it becomes pollution, damage, downtime or a compliance headache. Official guidance also states that a bund should be impermeable to oil and water and should not have a pipe, valve or opening that allows it to drain.

What doesn’t count as secondary containment?

Again, the Oil Storage Guidance in England and Wales point out that ‘double-skinned’ or ‘twin-walled tanks’ – where the tank is surrounded by a second outer skin for extra strength – and oil separators don’t qualify.

Why Are Bunds Important?

There might be no use crying over spilt milk, but spilt oil, fuel, or other potentially harmful liquids give plenty of cause for tears. If they escape the primary container and reach the ground or drainage system, the consequences can stretch well beyond a bit of a messy yard.

GOV.UK’s Pollution Prevention Guidance is very clear that surface water drains discharge directly to the environment, and contaminated water from business activities must go to the foul drain with permission, or be recycled or removed by a registered waste carrier.

That’s why bunds are so important. They help you:

  • Contain leaks at source
  • Reduce the risk of land and water pollution
  • Protect surrounding equipment and infrastructure
  • Make clean-up simpler and more controlled
  • Maintain safer storage areas for oils, fuels and chemicals

For many oil storage setups, bunding isn’t just the sensible thing to do; it’s actually built into the expectations set out in the official guidance.

What Can a Bund Be Used For?

Bunds are commonly used anywhere a site stores liquids that could pollute if released. That includes oil, diesel, other fuels, lubricants, chemicals and certain waste liquids. There are several types of bunds, each with different uses. Here are some of the most common:

Oil bund

Used around tanks, drums, or containers storing oil. This is one of the most common applications, especially where sites store heating oil, diesel, lubricants, or waste oil.

Fuel bund

Used for diesel, gas oil and other fuel storage where a leak could create pollution, fire risk or operational disruption.

IBC bund

Used beneath or around intermediate bulk containers to catch leaks, drips or overflows.

Drum bund or barrel bund

Used for smaller containers, usually where multiple drums are stored together. A drum bund may be a purpose-made sump pallet or drip-tray arrangement designed to catch leaks from the drums above.

Spill bund or spill barrier bund

These terms are often used more loosely for containment used during storage, maintenance or transfer activities. On site, they’re usually about controlling spill risk within a defined area.

Bunded tank

This usually refers to a tank with built-in secondary containment, often called an integrally bunded or pre-bunded tank.

How Big Should a Bund Be?

With the whole point of a bund being to capture any overspilling liquid from the container(s) it’s protecting, capacity is crucial to get right.

  • For a single fixed tank, IBC, mobile bowser or similar single container: the bund should hold 110% of the container’s capacity.
  • For multiple fixed tanks, bowsers or IBCs stored within the same secondary containment: the bund should hold whichever is greater – 110% of the largest container or 25% of the combined capacity of the containers.
  • For drums: the secondary containment is usually sized to at least 25% of the capacity being stored on the tray.

So if someone asks, “how much liquid should a bund hold?”, the simple answer is: more than the container itself, so there’s still spare capacity if something goes wrong.

How to Empty a Bund Safely

Without any pipes, valves or openings, you may wonder how to empty a bund – it’s important to know the answer, as it can be tempting to look for shortcuts.

#1 Start by asking what’s in the bund

It might look like rainwater, but appearance alone proves very little. Bund contents may include rainwater, product residues, oil traces, sludge, washdown contamination or a mixture.

#2 Check for signs of contamination

Look for sheen, odour, staining, sludge, discolouration or product around the valves, pipework and connections of your primary containers. If there’s any doubt, treat the contents as potentially contaminated until you know otherwise.

#3 Don’t send contaminated liquid to surface water drains

This is a big one. Surface water drains discharge directly to the environment. Official guidance says contaminated water must go to the foul drain only with permission from the water company, or be recycled, treated or removed by a registered waste carrier.

#4 Use a controlled removal method

The safe option depends on what’s in the bund. That may involve:

  • Removing liquid by vacuum or pump-out
  • Sending it for treatment or disposal
  • Discharging to foul sewer only where appropriate permission is in place
  • Arranging collection by a registered waste carrier

#5 Investigate why liquid built up in the first place

Emptying a bund is only half the job. If the liquid is there because of a leak, overfill event, poor housekeeping or damaged equipment, it will happen again unless the root cause is addressed.

#6 Record what was found and what was done

If bund pump-outs are recurring, keep a simple record. It helps spot patterns and gives you a better handle on whether the issue stems from weather, maintenance, or operations.

Why Bund Overfilling Happens

It may seem obvious, but it often creeps up quietly. Everything looks fine, nobody notices the liquid level rising until capacity has been eaten away.

The most common causes include:

Weather

Open bunds can collect a surprising amount of rainwater over time.  Where health and safety allow, you could put a roof over the bund to stop rainwater accumulating.

Neglect

A bund can be perfectly designed and still fail in practice if nobody checks it. A slow buildup of water, debris, or product residues reduces the space available for an actual incident to occur.

Spillages during transfer

Small transfer losses often get dismissed because they end up where they’re supposed to – inside the bund. But repeated spillages still take up capacity and still need managing.

Leaking valves, fittings or pipework

A bund that’s filling up without obvious bad weather may be telling you something. Secondary containment shouldn’t be viewed as a substitute for maintenance.

Overfilling of the primary container

If the tank or IBC is overfilled, the bund may contain the overflow. That’s exactly what it’s there for, but once it happens, the bund needs attention.

In many cases, bund overfilling isn’t caused by a single event, but by small, repeated issues that go unnoticed over time.

Why Bund Overfilling Is Such a Problem

A bund that’s already partly full has less room to do its job.

That means if a tank leaks or a delivery goes wrong, the remaining capacity may not be enough to contain the loss – your secondary containment will no longer be giving you the protection you need. It also creates other problems:

  • Higher chance of polluted overflow
  • More difficult inspections
  • Hidden leaks going unnoticed
  • Higher clean-up costs later
  • Avoidable disruption to operations

How to Prevent Bund Overfilling

Prevention is the best approach, and it’s much easier than emergency bund emptying.

Inspect bunds regularly

Don’t wait around for annual reviews. A simple visual check can pick up on rainwater buildup, staining, damage, debris and obvious signs of leakage early.

Keep the bund area clear

Debris takes up capacity, block inspection points, and makes it harder to spot a problem.

Investigate recurring liquid buildup

If one bund always seems to need emptying, that’s useful information. It may point to poor drainage controls, a faulty valve, a transfer issue or a design problem.

Consider weather protection where suitable

Covers or roofs can reduce rainwater buildup in some setups, provided the arrangement remains safe and suitable for your site.

Review transfer practices

Many bund problems begin during deliveries, decanting, or routine handling, not from dramatic tank failures.

Make ownership clear

Bunds are easy to ignore when nobody is clearly responsible for checking them. Assign ownership and make inspections part of routine site housekeeping.

How to Dispose of Unknown Chemical Waste

You may never have seen a UFO – but many businesses have encountered UCW – Unidentified Chemical Waste.

It usually shows up quietly – a cupboard of old unlabelled bottles, the odd mystery drum in the corner of a warehouse, the box of ‘lab leftovers’ with no paperwork. It’s especially common after staff turnover, site shutdowns, refurbishments or when Facilities Management (FM) teams take on a new contract and inherit whatever the previous incumbent left behind.

If you don’t know exactly what a substance is, you can’t safely store it, transport it, classify it, or dispose of it. And when ‘mystery chemicals’ sit around long enough, they get more unstable, more expensive to remove, and more likely to cause an incident.

This guide explains how UK businesses should approach unknown chemical disposal safely, legally, and without guesswork.

  • What Counts as ‘Unknown Chemicals’?
  • What to Do if You Find Unknown Chemicals on Site
  • 5 Things to Never Do with Unknown Chemical Waste
  • Triage the Risk Before You Do Anything
  • The Usual Suspects: Legacy and Out-of-Date Chemicals
  • The Compliant Route for Unknown Chemical Disposal
  • How to Prevent Unknown Chemical Buildup

What Counts as ‘Unknown Chemicals’?

We’ve already covered the definition of ‘chemical waste’, and ‘how to dispose of chemical waste’ in other blogs, so for the purposes of this one, unidentified chemical waste includes any substance for which you cannot confidently confirm what it is and how it should be handled. This might be:

  • Containers with missing, damaged, faded, or handwritten labels.
  • Decanted liquids in unmarked bottles (a classic on industrial sites).
  • Mixed containers with no Safety Data Sheet (SDS).
  • Old stock with no purchase records following ownership or management changes.
  • Drums or IBCs where the contents don’t match the label.
  • Lab chemicals past their use-by date with unclear history.
  • Waste containers where streams may have been mixed.

Many substances are colourless, and some of the most problematic materials only become obvious when something goes wrong – vapours, reactions, pressure build-up, corrosion, or leaks.

As a rule, if you can’t confidently identify a substance, it should be treated as potentially hazardous until assessed, even if it looks harmless.

When Does a Chemical Become Waste?

This is an important legal point under UK waste legislation, as a chemical isn’t considered waste until the holder:

  • Discards it,
  • Intends to discard it,
  • Or is required to discard it.

Old stock sitting in stores isn’t automatically considered as waste. However, once a decision is made to remove it – because it’s redundant, out of date, or no longer usable – hazardous waste regulations may apply.

What to Do if You Find Unknown Chemicals on Site

If you’ve found mystery containers and you’re wondering what to do, here are the immediate actions you should take:

  • Stop and assess. Don’t rush into tidying up.
  • Restrict access. Isolate the unknown chemicals and limit handling to trained personnel to avoid accidental use.
  • Don’t open, sniff, or decant containers. Informal testing methods create incidents – please don’t sniff anything.
  • Photograph everything exactly as found. Capture labels, condition, and location.
  • Create a basic inventory. Container type, approximate volume, condition, and markings.
  • Look for obvious hazards from a safe distance. Leaks, staining, corrosion, crystallisation, bulging lids, strong odours, heat or fumes.
  • Keep away from drains and ignition sources. Unknown liquids and solvents can present both fire and environmental risk.
  • Separate obvious incompatibles only if safe to do so. For example, acids away from alkalis – but avoid moving containers unnecessarily.

You can also refer to the HSE COSHH guidance for further clarification on safe handling and exposure control. If anything seems off or you spot any obvious hazards, treat it as a higher risk and escalate to a competent waste specialist for response.

Five Things to Never Do with Unknown Chemical Waste

This was almost a list of six things, but we’re confident you won’t try to eat or drink any of the unidentified chemicals… will you? Some mistakes are obvious. Others are surprisingly common – and far more dangerous.

#1 Don’t test it informally.

Mixing small amounts, adding water or using basic test strips on unknown substances can trigger reactions.

#2 Don’t consolidate containers.

The ‘let’s pour all the half bottles together ’ approach is a fast way to create toxic gases or heat-generating reactions. Mixing waste streams without assessment can also change hazard properties and create new classification obligations.

#3 Don’t store unknowns with general waste or in accessible areas.

Unsecured storage increases exposure and liability.

#4 Don’t transport them as a ‘quick job’

Movement of chemicals may fall under dangerous goods regulations and must be properly assessed.

#5 Don’t assume age makes it harmless.

In some cases, age increases instability or container degradation.

When in doubt, treat unknowns as hazardous until identified.

Triage the Risk Before You Do Anything

Not every unknown chemical situation is an emergency. However, a sensible triage approach helps determine urgency.

Low risk indicators (still handle carefully)

  • Small sealed containers in good condition.
  • Original packaging with partial label info.
  • Stored appropriately with no signs of leakage.

Medium risk indicators

  • Damaged labels, unknown age, mixed assortment.
  • Poor storage conditions (heat, sunlight, near drains).
  • Strong smells, minor staining, unknown residues on the outside.

High risk indicators (stop and get specialist help)

  • Leaking containers or corrosion.
  • Crystallisation or bulging lids.
  • Unidentified pressurised containers (aerosols or cylinders).
  • Large volumes in drums or IBCs with unclear history.
  • Any visible fumes, heat, or reactions.

In most cases, involving a competent hazardous waste specialist is the safest approach. The triage process simply helps you understand the level of urgency.

The Usual Suspects: Legacy and Out-of-Date Chemicals

Unknown chemicals don’t appear out of nowhere; there are patterns, such as sites accumulating ‘just in case’ stock.

On manufacturing sites

  • Process changes leave redundant raw materials.
  • Shutdowns and decommissioning projects leave partially cleared stores.
  • QA reagents remain after testing methods change.
  • Maintenance chemicals get forgotten in workshops.

Linking legacy chemicals back to purchase records and Safety Data Sheet documentation makes assessment significantly easier and more cost-effective.

Out-of-date chemicals

Chemical expiration doesn’t always mean unsafe. However, it can mean:

  • Degraded containers
  • Changed hazard classifications
  • Uncertainty around stability

Out-of-date chemical disposal should be treated as a structured compliance and safety task – not a simple housekeeping chore.

Laboratory environments

When it comes to unknown lab waste, some of these open up new cans of worms and introduce their own complexities:

  • Decanted bottles with handwritten notes.
  • Mixed small volumes and ‘mystery’ sample vials.
  • Cabinets inherited after staff turnover.
  • Legacy reagents with unclear history.

Delaying action rarely improves the situation. The safest route is usually inventory, secure storage, competent assessment and finally, planned removal – as opposed to “Let’s deal with it on a quiet Friday…”

Who Is Responsible for Unknown Chemical Waste?

Waste responsibility in general is often misunderstood. Under Duty of Care obligations, any business that produces or holds waste is responsible for it from the point of generation through to final disposal. The process involves ensuring that the waste is accurately described, correctly classified, and transferred only to an authorised party.

For Facilities Management providers, responsibility for unknown chemicals should ideally be clarified during contract mobilisation. However, once in control of a premises, there is still a duty to manage risks appropriately – even where materials were left by a previous occupier.

“The previous incumbent left it behind” doesn’t remove the need to manage it safely, or the fact that you’ve inherited the responsibility to do so.

The Compliant Route for Unknown Chemical Disposal

If you’re wondering about the best way to get rid of unknown or unwanted chemicals, here’s what a safe, compliant, and structured approach looks like.

Step One: Site Assessment and Inventory

A structured inventory is the backbone of safe waste removal. You need to identify:

  • What containers exist, where they are, their condition and volumes.
  • Any visible hazards, and whether anything needs urgent containment.
  • A segregation plan to prevent incompatibles from being packed or stored together.

Step Two: Classification, Segregation and Safe Packing

Even if you can’t fully identify every item, you can often classify waste streams sufficiently for safe handling and legal paperwork. Materials can often be assessed using:

  • Available documentation
  • Packaging information
  • Hazard indicators
  • Professional judgement

This enables appropriate handling and documentation.

Unknowns are usually managed by:

  • Keeping original containers closed and intact where possible.
  • Using compatible secondary packaging (overpacks) for any damaged items.
  • Separating broad hazard families based on evidence and assessment – not guesswork.

For detailed guidance on waste assessment and hazard classification, refer to the Environment Agency’s WM3: Waste Classification and Technical Guidance.

Step Three: Collection, Documentation and Disposal

Where materials are classified as hazardous, a hazardous waste consignment note will be required. In England and Wales, records must be retained for at least three years.

Transport must be arranged appropriately, and shortcuts at this stage can result in rejected loads, enforcement action or serious incidents.

Final disposal routes depend on classification, hazard properties, and available treatment options.

Mystery chemical disposal is therefore best approached as a managed process – identify what can be identified, control what we can’t, and maintain traceability throughout.

How to Prevent Unknown Chemical Buildup

You’ve got this far, your site is now free of any mystery drums and suspicious liquids, but what’s next? Prevention – the top of the waste hierarchy. Preventing a repeat scenario will save you time, money, and risk.

Practical steps include:

  • Introduce a ‘no label, no storage’ rule – if it’s decanted, it must be labelled immediately. Even restaurants have this rule, and let’s face it, unlabelled passata is far less worrisome than pesticides or acids.
  • Maintain a chemical register – even a simple spreadsheet will do the job.
  • Keep Safety Data Sheets current and accessible.
  • Schedule periodic stores audits and clear-outs.
  • Improve stock control to reduce redundant chemicals.

For Facilities Management teams, it’s worth building out a mobilisation checklist that includes:

  • Walkdowns of stores, plant rooms and labs.
  • Photo inventories at handover.
  • Clear agreement on responsibility for legacy materials.

Prevention sits at the top of the waste hierarchy. Better upstream control reduces risk, cost, and downstream compliance pressure.

A Practical 4-Week Framework to Reduce Downstream Fire Risk

Fancy reading a 60-page strategy document to reduce downstream fire risk? No? That’s handy, as we didn’t much fancy writing one, but we did create a simple framework you can use…

Reducing downstream fire risk starts with the everyday disposal decisions made on your site – often by people who aren’t thinking about fire at all. Under the UK Waste Duty of Care, your responsibility for waste doesn’t end when it leaves your site. If that waste contributes to a fire further down the chain, the question won’t just be “what happened?” – it will be “what steps were taken to prevent it?”

If you’ve already explored the common causes of waste and recycling facility fires, this article focuses on implementation – the practical steps you can take to prevent those causes from being triggered in the first place.

This 4-week framework will enable you to reduce downstream fire risk in a structured, manageable way – making sure your waste doesn’t become someone else’s emergency.

  • What You’ll Achieve in Four Weeks
  • Week One: Establish Control at the Point of Generation
  • Week Two: Build Understanding, Not Just Awareness
  • Week Three: Align Storage, Handling and Internal Checks
  • Week Four: Lock It In with Documentation and Review
  • Parting Thoughts
  • Reduce Downstream Waste Fire Risk with Hazport

What You’ll Achieve in Four Weeks

If you follow the steps in this framework, by the end of a 4-week period, you should be able to say:

  • “High-risk waste can’t accidentally end up in general waste or mixed recycling.”
  • “It’s not just throwing something in a bin; it affects real people.”
  • “Segregated waste stays segregated – from point of generation to final disposal.”
  • “Our paperwork and waste descriptions tell the true story of our waste.”

Amongst many other positive statements, all of which are much better than: “We’re ever so sorry our waste caused a huge fire in your recycling facility, we’ll try not to do it again…”

After all, who wants to say that?

Before You Start

Take just 15 minutes to save potential weeks of frustration and give the framework its best firefighting chance:

  • Pick a project owner who can actually influence day-to-day behaviour – perhaps someone in facilities or ops.
  • Choose your top three fire-relevant waste streams on site – no need to try and fix everything at once, and overcomplicating things.
  • Decide what ‘good’ looks like (e.g. batteries never appear in general waste, aerosols always go into a dedicated container, etc.)

With these things in place, you’re good and ready to run your 4-week downstream fire risk reduction plan at any time – no need to wait for a new month, a full moon, or any other strange starting period to get fire safety management in place for your site.

Week One: Establish Control at the Point of Generation

Most downstream fire risk is introduced where waste is generated, not in the waste hold. Week one is all about removing guesswork so high-risk items don’t drift into the general waste or mixed recycling streams.

Here’s the plan for week one:

#1 Identify your site-specific fire-risk wastes

Generic lists are useful, but you need to capture the reality of your facility. Common examples include:

We wrote a whole blog on the common causes of waste and recycling facility fires that can help you determine which wastes your facility produces that could be a secret (or not-so-secret) downstream fire risk.

#2 Map where they’re generated

Maintenance bays, goods-in, IT rooms, cleaning stores, production lines… fire-risk waste appears in predictable places – places your waste containers should live too.

#3 Put dedicated, clearly labelled containers at the source

Don’t place a battery bin just ‘somewhere in the yard’ and hope everyone will use it. Put it where the disposal decisions happen and remove ambiguity with rules that don’t bend:

  • Batteries NEVER go in general waste or mixed recycling.
  • Aerosols are segregated EVEN if they seem empty.
  • Oily rags DO NOT go in open bins or piles; they go into a dedicated lidded container.

Week one outcome: Nobody on site should have to think about or decide where risky waste goes; the system should decide for them and be simple enough to become second-nature.

Week Two: Build Understanding, Not Just Awareness

Mis-segregation is usually down to habit, assumptions, or uncertainty. These are all things that signage and posters can help with, but are not enough by themselves to rectify.

Week two is about short, role-specific training that explains why the rules exist.

#1 Train the people who actually handle waste

Think maintenance, cleaners, production operatives, facilities teams – keep it simple and on the floor at the waste points. A 15-minute or so session with occasional refreshers will be far more effective than a three-hour presentation once in a blue moon that sends everyone to sleep – including the presenter.

#2 Explain downstream consequences in plain language

The illustrations and examples hit home because they’re real and understandable:

  • Batteries often ignite after they’re damaged in handling or processing, not at the bin.
  • Aerosols can rupture when heated or crushed, as opposed to when sitting in the bin.
  • Oily rags can self-heat and combust if not contained properly.

#3 Reinforce with visuals where waste is generated

This is where your posters and signage come into play – as a reinforcement, not as the only form of training provided. A small prompt at the point of decision beats a long policy hidden in an old folder on a dusty shelf.

Week two outcome: Staff understand that this isn’t about micro-managing or box-ticking but about preventing your waste from becoming someone else’s emergency.

Week Three: Align Storage, Handling and Internal Checks

This is where good segregation at source can easily be undone – bins get swapped, waste is consolidated to ‘save space’, lids are left open, and the waste streams quietly recombine – creating exactly the kind of conditions that

 lead to downstream incidents.

Week three is about keeping your well-established system intact under the day-to-day pressures of a busy workplace.

#1 Review how segregated waste is stored and moved

Check:

  • Where it sits before collection.
  • Whether it’s moved through busy areas.
  • Whether it’s beingconsolidated (and whether it should be).

#2 Re-check the basics that prevent escalation

High-risk wastes should be:

  • Kept away from heat sources and ignition points.
  • Not stored next to combustibles.
  • Not building up beyond sensible volumes.
  • Stored in appropriate containers.

#3 Add a light-touch internal check

Something like a weekly 10-minute audit, with a simple walkaround by your designated project owner, can work well if kept consistent. They can spot-check the fire-relevant streams and correct any issues early – quietly and constructively – before bad habits have the chance to settle.

Week three outcome: Segregation still looks right on a Friday afternoon, not just after a Monday toolbox talk or brief audit.

Week Four: Lock It In with Documentation and Review

This is where ‘what we do’ becomes ‘how we operate’, and where your Duty of Care becomes real-world practice and second nature for everyone.

Under the UK Waste Duty of Care, businesses must take reasonable steps to prevent waste from causing harm. That responsibility includes taking reasonable steps to prevent waste from being misdescribed, mis-segregated, or packaged in a way that creates avoidable risk further down the chain.

#1 Check waste descriptions and paperwork match reality

If your documentation doesn’t reflect what’s actually in the container, risk travels downstream under the wrong label and poses a risk to all who come into contact with it.

Always review:

  • Waste descriptions for your key streams.
  • Container labels.
  • Any recurring contamination and mis-segregation issues.

#2 Confirm acceptance criteria with your waste contractor

Ask (and document):

  • What must be segregated.
  • How it should be packaged.
  • What they will reject – and why.

This will help prevent the classic “it’s never been a problem before” surprise.

#3 Capture the process in usable formats

Forget 40-page handbooks and long-winded SOPs. Instead, create tools people will actually use, and genuinely see the value in:

  • One-page waste handling summaries for each stream.
  • A simple waste flow diagram poster.
  • New-starter refresher notes.
  • Short and engaging toolbox talks and micro-training clips for common issues.

#4 Set a trigger-based review cycle

Don’t just establish this entire system and leave it to the wind; review your system:

  • After process changes.
  • Whenever new products or materials are introduced.
  • After near-misses, rejected loads, or contamination and mis-segregation issues.

Week four outcome: The system survives staff changes and turnover, busy periods, and those pesky “we’ll deal with it later” moments.

Parting Thoughts

Waste facility fires cannot really be chalked up to a simple case of ‘bad luck’. In almost every case, they’re the result of disposal decisions being made without thought or understanding of what happens downstream, and who may be at risk.

This 4-week framework is about removing ambiguity and building habits that make the safe (and right) option the default, starting where the risk enters your waste stream.

Common Causes of Waste and Recycling Facility Fires

Do you know the common causes of waste and recycling facility fires? How about the business wastes most likely to trigger them?

Waste and recycling facility fires rarely start with something dramatic. More often than not, it’s an item deemed as ‘safe’ put in the wrong bin, or a small amount of contamination in the wrong container. This usually becomes a problem later – once it’s been compacted, shredded, baled, crushed, heated or mixed with other materials.

This matters for UK businesses because the biggest levers for prevention sit upstream, where the waste is produced. So let’s take a dive into that to find out how you can avoid a downstream fire.

The Business Wastes Most Likely to Cause Fires

Let’s look at the most likely hazardous business wastes to cause downstream fires and what to do about them, as well as a few misconceptions cleared up – no scare tactics, no jargon, just information that can help your business avoid these issues.

Lithium Batteries

Most common culprits:

  • Batteries and battery packs used in power tools, laptops, e-bikes and e-scooters.
  • Vapes (especially disposables), power banks, handheld scanners and radios.
  • Equipment with embedded cells, such as lights, alarms, sensors and small electronics.

Cause of fire:

When damaged, lithium batteries can enter thermal runaway – often after compaction or shredding – creating intense, rapidly developing fires that are difficult to extinguish.

Common misconception:

“Surely they can’t do much damage, they’re tiny.”

Small cells can produce enough heat to ignite surrounding paper, plastics, films and residual flammable contamination. The issue isn’t just the battery; it’s the fuel package around it.

Tips for avoiding lithium battery fires:

  • Never place batteries in general waste or mixed recycling.
  • Set up a dedicated battery segregation point where batteries are removed at source.
  • Tape terminals to prevent short circuits.
  • Store batteries in a non-combustible lidded container; keep damaged or swollen batteries separate and clearly marked.
  • Keep storage cool, dry and away from flammables.
  • Train staff to spot ‘battery-in-disguise’ items like vapes and other small electronics.

See our complete guide to lithium battery disposal for UK businesses.

Aerosols and Pressurised Containers

Most common culprits:

  • Aerosol lubricants, spray paints, cleaning sprays, adhesive sprays.
  • Camping gas cylinders, CO2 cartridges and small LPG cylinders.
  • Nitrous oxide canisters (increasingly seen in waste streams).

Cause of fire:

Even ‘empty’ aerosols often retain propellant or residue. When heated or crushed, they can rupture – turning into a projectile and dispersing flammable product. The Fire Protection Association notes flammable aerosols can be more hazardous than some flammable liquids because containers can rupture and spread burning liquid.

Common misconception:

“It’s safe as long as it feels empty.”

An aerosol isn’t safe because it feels empty; it’s safe when it has been properly managed as pressurised waste.

Tips for avoiding aerosol and pressurised container fires:

  • Segregate aerosols and canisters into a clearly labelled, dedicated container.
  • Don’t puncture or crush unless you have a compliant system designed for it.
  • Keep away from heat sources and direct sunlight.
  • If you produce high volumes of this waste, implement a documented process as part of your site’s dangerous goods and fire safety controls.

Flammable Liquids and Solvent-Based Wastes

Most common culprits:

  • Solvent thinners, acetone, degreasers and fuels.
  • Solvent-based paints, varnishes, resins and adhesives.
  • Contaminated rags, wipes, absorbent pads and spill kits.

Cause of fire:

Flammable liquids produce vapours which can ignite easily in the right concentration. UK workplaces are expected to manage these hazards in accordance with the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR).

Common misconception:

“There’s only a little bit left; it won’t cause any harm.”

Small residues still give off gas vapours, and many small residues together can create a higher volume of vapour.

Tips for avoiding flammable liquid and solvent-based fires:

  • Keep flammable liquids in original containers where possible, sealed and upright.
  • Segregate flammable liquid waste from oxidisers and reactive chemicals.
  • Store in suitable, labelled containers and secondary containment such as bunding where appropriate.
  • Don’t ‘make space’ by combining different solvent wastes unless you’ve confirmed compatibility and that your waste contractor will accept it.

Oily Rags and Self-Heating Wastes

Most common culprits:

  • Rags or wipes with linseed oil, wood oils, some paints and stains.
  • Oily absorbents from maintenance work (hydraulic oils, lubricants).
  • Some organic/warm loads such as compostable residues and biomass fines.

Cause of fire:

Self-heating is an internal chemical process in which oxidation generates heat; if the heat can’t escape, the temperature rises until ignition.

Common misconception:

“Spontaneous combustion is a myth.”

It’s not. It’s spontaneous human combustion that’s the myth. Spontaneous combustion, in itself, is a recognised ignition mechanism, especially in certain oils and porous materials that trap heat.

Tips for avoiding oily rag and self-heating waste fires:

  • Don’t let oily rags accumulate in open piles or general waste.
  • Use a dedicated, lidded metal container for oily rags and absorbents.
  • Keep this stream separate from general combustibles like paper, card and plastics.
  • If you frequently generate oily absorbents, create an SOP and train staff on proper handling and disposal.

Oxidisers and Reactive Chemicals

Most common culprits:

  • Swimming pool and spa chemicals (oxidisers), peroxides, certain laboratory chemicals.
  • Strong cleaning oxidisers used in food production, facilities, healthcare.

Cause of fire:

Oxidisers don’t have to ‘burn’ themselves to create a fire – they can accelerate combustion or react dangerously with organics or other incompatible materials.

Common misconception:

“It’s not flammable, so it can be stored with general chemicals.”

Oxidisers are often worse when mixed incorrectly because they can intensify fires in surrounding materials. Guidance on incompatibility is blunt: mixing incompatible chemicals and wastes can create heat, over-pressurisation, and fire.

Tips for avoiding oxidiser and reactive chemical fires:

  • Keep oxidisers in original packaging, sealed, dry and segregated from organics and flammables.
  • Never dispose of ‘unknowns’ by combining them.
  • If you have multiple chemical streams, implement a compatibility check process – this could be as simple as a flowchart poster or checklist.

Hot Loads and Legacy Ignition Sources

Most common culprits:

  • Ashes, hot metalwork residues, heat lamps, heaters.
  • Smoking materials in general waste.

Cause of fire:

Smouldering material can sit unnoticed in a skip or bale until oxygen is introduced during movement.

Common misconception:

“If it’s not visibly glowing, it’s cooled down enough to be disposed of.”

Have you ever cleaned a firepit or chiminea the morning after using it? They’re usually still warm, right? Ash and fine residues can retain heat for a long time – especially when insulated by a bag, mixed with cardboard, or stored near other combustibles. It doesn’t need flames at the point of disposal to become a downstream ignition source.

Tips for avoiding a hot load and legacy ignition fires:

  • Don’t dispose of warm or hot materials until fully cooled and verified.
  • Use metal bins for ash-like materials and keep separate from combustibles.

Why Waste Fires Occur Downstream

Which of your own waste streams could spark (pardon the pun) one of these scenarios tomorrow for your local waste or recycling facility?

There are several reasons hazardous waste can cause downstream fires, and if your business produces any hazardous waste, it’s worth knowing.

Hidden Ignition Sources

Items that can ignite when damaged – especially lithium batteries – enter general waste or recycling streams and then get crushed or punctured during handling or processing. The Waste Industry Safety and Health Forum (WISH) highlights battery fires occurring in reception, storage, and processing areas, as well as being a risk to picking-cabin workers.

Pressurised Containers Rupturing

Aerosols and gas canisters can burst under heat or pressure, becoming projectiles and spreading burning material.

Flammable Vapours Finding an Ignition Point

Solvent-based wastes can release vapours that ignite if stored/handled poorly. The HSE’s guidance on flammable liquid storage focuses on controlling vapours and ignition sources.

Self-Heating (Spontaneous Combustion)

Some wastes generate heat internally (oxidation/exothermic reactions). If that heat can’t escape, the temperature rises until ignition.

A good example of this is hay. Hay spontaneously combusts when moisture levels are high during baling. This causes microorganisms to break down organic matter, generating immense internal heat. That’s why you should always make hay while the sun shines…

Incompatible Chemicals Reacting

Mixing ‘unknowns’ or storing reactive materials together can generate heat, gases, or violent reactions. Chemical incompatibility guidance is clear: mixing incompatible wastes can cause fire or over-pressurisation.

A Lecture-Free Note on Waste Compliance

Under the UK Waste Duty of Care, businesses must take reasonable steps to prevent waste causing harm to people or the environment. This doesn’t only apply to your site; it also applies downstream at every stage of the waste journey. In practice, that means storing waste safely, describing it accurately, and keeping high-risk items like batteries, aerosols and flammable residues out of the wrong streams.

The fire risk doesn’t disappear when waste is incorrectly segregated or misclassified; it moves downstream, but the liability and consequences remain with the waste producer.

Your Waste Duty of Care isn’t just paperwork or unnecessary regulation; it’s about stopping your waste from becoming a risk to someone else. Correct segregation, storage and waste descriptions are how businesses meet that obligation in practice.

Closing Takeaway

Waste facility fires are rarely caused by ‘bad luck’. They’re usually caused when everyday waste decisions are made without understanding how that waste behaves later in the chain. One preventable item being treated as ordinary waste is all it takes.

If your business produces any of the waste types or streams above, the goal isn’t to panic; it’s to put clear controls in place so the risk doesn’t travel downstream. Getting segregation, handling, and storage right at the source, and backing it up with ongoing training and culture is one of the most effective – and overlooked – fire-prevention measures available.

How to Dispose of Antifreeze

Antifreeze might keep your systems running cool and smooth – but dispose of it incorrectly, and things can heat up fast for your business.

If your business services vehicles, runs a fleet, operates plant equipment or maintains HVAC/generator systems, there’s a good chance you’ll produce used antifreeze/engine coolant at some point. And when it’s time to change it, you need a plan, because improper antifreeze disposal can quickly become an environmental incident and a paperwork nightmare.

This guide is written for UK businesses, and we’ll cover what antifreeze is, whether it’s the same as coolant, why it’s often classed as hazardous waste, and how to dispose of antifreeze compliantly.

  • What Is Antifreeze?
  • Why Is Antifreeze Considered a Hazardous Waste?
  • Where Should I Pour Leftover Antifreeze?
  • What Not to Do with Leftover Antifreeze?
  • Where Does Antifreeze Go When Disposed of Correctly?
  • Antifreeze Disposal: A Practical Step-by-Step for Businesses
  • Can Antifreeze Be Recycled?
  • How Do You Neutralise Antifreeze?
  • Need Help with Antifreeze Disposal?

What Is Antifreeze?

Antifreeze and engine coolant are closely related chemical fluids, typically a mix of a glycol-based chemical and water used in engines and some cooling systems to control temperature and protect components. In plain terms, it helps stop systems freezing in winter, boiling in summer, and corroding over time. Antifreeze is closely tied to the term coolant, but there are differences.

Is Antifreeze the Same as Coolant?

Not exactly. They’re closely related, but they’re not the same thing.

Antifreeze (usually concentrate)

In most cases, antifreeze refers to a concentrated glycol-based product (often ethylene glycol, sometimes propylene glycol) blended with corrosion inhibitors and other additives. On its own, it’s typically not intended to be used neat in a vehicle cooling system.

Coolant/engine coolant (ready to use)

Engine coolant (or simply coolant) is the in-use fluid that circulates through the system. It’s usually a mixture of antifreeze and water, often around a 50:50 ratio (though manufacturers may specify different blends depending on application and climate).

What about ‘antifreeze coolant’?

People (and sometimes product labels) often use terms like ‘antifreeze coolant’ to mean one of two things:

  • Pre-mixed coolant (ready to pour straight into the system), or
  • Antifreeze concentrate sold with instructions to dilute before use.

Why is this important to know? Because if you’re searching for how to dispose of engine coolant, you’re typically dealing with the same waste stream used for antifreeze disposal – but classification can depend on what’s in it and what it’s been contaminated with.

Why Is Antifreeze Considered a Hazardous Waste?

Used antifreeze is commonly treated as hazardous because:

  1. The product itself can contain dangerous substances (depending on formulation).
  2. Once used, it can become contaminated with other hazardous materials (for example: oils, fuels, metals, or other workshop fluids).

That difference matters – because two containers of ‘used’ coolant on the same site can require completely different disposal routes.

UK waste classification uses EWC (European Waste Catalogue) codes to classify antifreeze correctly, and whether or not it’s hazardous:

  • 16 01 14* = Antifreeze containing hazardous substances (hazardous).
  • 16 01 15 = Antifreeze not containing hazardous substances (non-hazardous).

This difference in classification will affect the disposal route for antifreeze.

Where Should I Pour Leftover Antifreeze?

For businesses, the safest answer to this is:

  • Pour it into a dedicated, compatible, sealable container (usually HDPE) that’s in good condition and kept closed when not in use.
  • Keep it inside secondary containment (bunding) away from drains.
  • Label it clearly (e.g., used antifreeze/engine coolant – pending disposal – hazardous/non-hazardous) and keep incompatible wastes separate.

What Not to Do with Leftover Antifreeze

Never. Ever. Pour antifreeze, antifreeze coolant, or used engine coolant down a drain, toilet, sink, gully or outside drain – and don’t tip it onto the ground.

Glycol-based chemicals are highly polluting, and once it reaches drainage systems, it can end up:

  • In surface water drains (which often discharge straight to streams and rivers).
  • At a wastewater treatment works, where it can disrupt treatment processes.
  • Or in soil groundwater if it’s dumped outside or allowed to soak away.

It also poses a real risk to ecosystems, wildlife, and pets – spills can attract animals that enjoy its sweet taste, and ingestion can be fatal.

You also shouldn’t tip leftover antifreeze into IBCs or drums that previously held something incompatible, and definitely don’t decant it into a ‘mystery drum’. On that subject, please, for the love of all things sacred in the realm of compliance, don’t even have a mystery drum!

Additionally, the UK Vehicle Waste Classification guidance explicitly states that you must not mix antifreeze with other listed vehicle fluids such as oils, solvents, brake fluids, etc.

Antifreeze Disposal: A Practical Step-by-Step for Businesses

Here’s a simple step-by-step process you can follow on site to keep antifreeze disposal safe, compliant, traceable and most of all, drama-free. Remember too, that our experts are only a phone call away.

#1 Keep it clean (and separate) from the start

Before you even think about final disposal or paperwork, focus on prevention. Don’t mix antifreeze/engine coolant with other fluids – doing so makes classification harder, increases risk, and can push you into a more hazardous (and more expensive) disposal route.

#2 Identify what you actually have

Ask two quick questions:

  • Is it unused product (concentrate or pre-mix), or used coolant drained from a system?
  • Has it been contaminated (oil, fuel, ingress, metals, degreasers, ‘workshop soup’)?

This matters because used coolant can range from relatively straightforward to fully hazardous, depending on what’s in it.

#3 Classify it using the correct EWC code

The EWC codes for antifreeze are:

  • 16 01 14* = Antifreeze containing hazardous substances (hazardous).
  • 16 01 15 = Antifreeze not containing hazardous substances (non-hazardous).

#4 Store it safely on site

  • Use a compatible, sealable container (typically HDPE) in good condition.
  • Keep it closed, upright and bunded (secondary containment).
  • Label clearly: ‘Used antifreeze/engine coolant – pending disposal’ plus your classification where known.
  • Keep it away from drains and traffic routes (forklifts + chemical waste drums = preventable incidents).

#5 Use the right paperwork

In England and Wales, the paperwork you use will depend on the classification:

  • If it’s hazardous antifreeze (16 01 14*), it must move with a hazardous waste consignment note (HWCN).
  • If it’s non-hazardous antifreeze (16 01 15), it normally moves with a waste transfer note (WTN).

Whether it’s identification, classification or ensuring you have the right paperwork, a good waste partner can help you where needed and arrange testing or assessments, so you’re not guessing.

#6 Only hand it to authorised people

Your Duty of Care doesn’t end when the waste leaves your site. You must take reasonable steps to prevent escape/spillage, and to ensure your chosen waste carrier is properly authorised.

#7 Collection, transport and treatment

A compliant waste contractor will confirm that the classification and packaging of your waste are correct, collect the waste using suitable containment and vehicles, complete the relevant sections of your paperwork, and then take the waste to an authorised site for treatment.

#8 Keep your records and apply the waste hierarchy

Whatever type of waste you’re handling, you’re expected to apply the waste hierarchy, following its priority order where reasonable to do so. This helps ensure the most sustainable waste treatment routes are used.

So, how long do you need to keep hazardous waste consignment/waste transfer notes?

  • Hazardous Waste Consignment Notes (HWSNs) must be kept for at least three years.
  • Waste Transfer Notes (WTNs) must be kept for at least two years.

Can Antifreeze Be Recycled?

Sometimes, yes. If the antifreeze is suitable (and not heavily contaminated), it may be treated/recycled through specialist processes that purify it by removing contaminants, allowing it to be reprocessed into new antifreeze.

The right route depends on composition and contamination; it’s best not to assume it’s recyclable because it looks clean – classification comes first, then the best available option.

How Do You Neutralise Antifreeze?

On-site antifreeze neutralisation is not a recommended or typical compliance route for businesses producing coolant waste. This is because adding other chemicals to ‘treat’ antifreeze can actually create a new waste stream, new hazards, and new classification issues.

What you can do safely, however, is manage any spillages.

Here’s an easy way to safely manage an antifreeze spill:

  • Contain the spill.
  • Use absorbents.
  • Keep contaminated absorbents separate (these may become hazardous too).
  • Prevent any washdown to drains.

That’s a high-level overview at least, but we also have a blog on chemical spill response procedures you may find helpful.

Ultimately, if you need a treatment route for antifreeze, that should happen through a permitted facility as part of an agreed waste management solution – not improvised on the workshop floor.

Need Help with Antifreeze Disposal?

Hazport can help your business dispose of antifreeze using the ‘no guessing’ methodology. If your site regularly produces antifreeze (garages, automotive workshops, depots, plant maintenance, engineering sites, facilities teams, etc.), we can take the pain out of its compliant disposal.

  • Correct classification support (no more gambling on codes).
  • Compliant containers and segregation advice.
  • Scheduled collections that fit around your operation.
  • Consignment paperwork handled correctly.
  • Documented traceability and a straight-talking team when you need answers.

That’s the Hazport approach – hazardous waste made easy – fast response, clear guidance, and no jargon.

Lithium Battery Disposal for Businesses: A Guide to Compliance

Ever tossed a lithium battery away without giving it a second thought? You could be an unintentional firestarter.

Research shows that 54% of businesses have experienced incidents linked to lithium batteries, with one in five reporting fires or explosions. And with these batteries powering everything from laptops and handheld scanners to cordless tools and UPS modules, there’s no avoiding them in the workplace.

They’re compact, convenient and powerful – but when end of life or become damaged, they stop being a benefit and start becoming a risk.

This guide removes the guesswork and strips away the jargon to explain, in plain language, how UK businesses can manage lithium battery disposal safely, legally, and confidently – keeping your workforce protected and your workplace compliant.

  • What Is a Lithium Battery?
  • Where You’ll Find Lithium Battery Waste in the Workplace
  • What’s the Business Risk of Incorrect Disposal?
  • 6 Steps for Compliant Lithium Battery Disposal
  • The Dos and Don’ts of Lithium Battery Disposal
  • How to Respond to a Lithium Battery Fire
  • Recycling Routes for Lithium Batteries
  • Remove the Guesswork with Hazport

What Is a Lithium Battery?

‘Lithium battery’ is the umbrella term for batteries that use lithium chemistry to store energy. Under that umbrella sit two main types:

  • Lithium-ion (Li-ion) – the rechargeable subset, powering most modern technology and tools.
  • Lithium metal (primary) – non-rechargeable cells such as many button or coin batteries.

Why so widespread? Lithium is the lightest metal on the periodic table, meaning these batteries deliver high energy density whilst remaining compact and portable – a perfect match for modern devices and equipment.

Where You’ll Find Lithium Batteries in the Workplace

Lithium-ion (rechargeable):

  • IT equipment – laptops, mobiles, tablets, power banks.
  • Warehouse/production – barcode scanners, handheld terminals, robotics such as AMRs and AGVs.
  • Facilities/critical power – UPS modules, server room backups, energy storage.
  • Tools and equipment – cordless drills, saws, grounds maintenance kit.
  • Fleet/mobility – e-bikes, e-scooters, e-cargo bikes.
  • R&D – prototype cells, packs and modules.

Lithium metal (non-rechargeable)

  • Office/tech – coin cells in keyboards, mice, access fobs.
  • Safety and security – sensors, detectors, specialist cameras.
  • Industrial/lab – data loggers, instrumentation, metering devices.

It’s a good idea to create a simple internal register – what you have, where it’s stored, who’s responsible, and its condition. This is one of the easiest ways to improve safety and compliance across your site.

Need help creating a one? Our team can support you.

What’s the Business Risk Incorrect Disposal?

As we noted at the outset, 54% of businesses have experienced a lithium battery-related incident – this shows that lithium batteries bring real business-critical risks when mishandled:

Thermal runaway

Physical damage, overcharging, or internal faults can trigger rapid self-heating, venting, the release of toxic gases, and ignition.

Hidden hazards

‘Dead’ batteries can still hold a charge; unsuitable storage can lead to short circuits; poor packaging can ignite in transit.

Regulatory exposure

Lithium batteries fall into hazardous waste controls, ADR (transport of dangerous goods), and battery/WEEE producer responsibility rules. Getting it wrong risks fires, fines and reputational damage.

The answer isn’t panic – it’s good housekeeping and competent partners.

6 Steps for Compliant Lithium Battery Disposal

#1 Identify and Classify

  • Record chemistry: Lithium-ion or lithium metal.
  • Note form: Loose cells/modules/packs or embedded in equipment.
  • Check condition: Intact or damaged/defective. 

#2 Apply the Waste Hierarchy

  • Prevent: Avoid over-ordering, monitor battery health and rotate stock.
  • Reuse/repurpose: Consider manufacturer take-back schemes and second-life options.
  • Recycle: Prioritise routes that maximise resource recovery. Disposal should always be the last resort. 

See our blog on the waste hierarchy to learn more. 

#3 Package and Store Safely

  • Li-ion: Tape terminals, add inert cushioning and segregate suspect units.
  • Lithium metal: Keep dry, avoid water exposure and keep separate.
  • All damaged units: Isolate and await specialist overpacking.

#4 Choose a Licensed Waste Partner

Expect:

  • Waste carrier license.
  • ADR capability.
  • Evidence of authorised downstream facilities.
  • Clear, straight-talking advice and fast turnaround.

That’s the Hazport standard!

#5 Move Under ADR with Correct Paperwork

Your waste partner should manage:

  • UN numbers.
  • ADR labels.
  • Waste transfer/consignment notes.
  • Specialist provisions for packaging and transport.

#6 Verify Treatment and Close the Loop

Keep recovery documentation for:

  • ESG reporting.
  • Environmental audits.
  • Compliance evidence.

Damaged Lithium Battery Disposal (High-Risk Scenario)

Treat any of the following as a serious red flag:

  • Swelling
  • Hissing
  • Scorch marks
  • Electrolyte smell
  • Water damage
  1. Stop and isolate. Move the item (if safe) into a fire-resistant quarantine container, away from people and combustibles.
  2. No DIY Don’t try to open, flatten, cool with improvised methods, or try to charge, test, or disconnect cells.
  3. Call a specialist. Damaged/defective lithium batteries require special handling and UN-spec packaging for transport; they must be moved by trained personnel with the right materials and documentation.
  4. Record the incident. Note where it came from and how it was found – this helps with safe consignment and future prevention, as well as supporting classification and documentation. 

The result? A protected workforce, a safer workplace, compliant paperwork, and a clean and simple handover to an approved facility. No drama. No guesswork.

The Dos and Don’ts of Lithium Battery Disposal

Let’s start with the umbrella rules: Never open one inside a building… (just checking you’re still with us).

Do:

  • Keep Li-ion and lithium metal separate, as well as intact vs damaged units.
  • Use non-conductive, fire-resistant, lidded containers with inert cushioning.
  • Tape exposed terminals on loose cells and small packs.
  • Store cool and dry, away from heat, sunlight and pressure.
  • Label clearly and maintain an up-to-date inventory.
  • When unsure: stop, isolate and escalate to a specialist.

Don’t:

  • Don’t crush, puncture or dismantle packs – no DIY ‘battery surgery’.
  • Don’t mix batteries with WEEE, cardboard, metals or combustibles.
  • Don’t ‘test’ damaged batteries by charging them.
  • Don’t improvise packaging – ADR rules aren’t optional.
  • Don’t move damaged/defective units without specialist UN-approved overpacking and paperwork.

Type-Specific Notes:

Lithium-ion (rechargeable subset)

  • Biggest risk: Thermal runaway.
  • Damaged Li-ion must be packed and shipped under special ADR provisions.

Lithium metal (non-rechargeable)

  • Water-reactive – Keep dry and away from moisture.
  • Prevent short circuits with proper terminal protection and separation.

One thing to remember:

If it’s damaged, unknown or making you nervous –  stop and isolate. Call a specialist to classify and package your lithium battery waste.

How to Respond to a Lithium Battery Fire

Knowing how to handle hazardous waste in an emergency is crucial for any business that produces or uses hazardous materials.

Always put people before property. If there’s smoke, flames, popping, or toxic vapour: evacuate the area, raise the alarm, and call 999.

For a lithium-ion battery fire: if it’s safe to attempt first-aid firefighting and you’re trained to do so, cool aggressively with water from a distance to stop thermal runaway spreading. Water helps remove heat even if flames reappear. A CO2 or foam extinguisher may knock down the flames, but cooling is critical to prevent re-ignition.

For lithium metal battery fires: DO NOT USE WATER. Use a Class D (metal fire) agent in line with your fire strategy and training.

For large packs (e-bikes, UPS, energy storage systems): Isolate, evacuate and let the fire service handle it. They may apply large volumes of water for extended cooling.

Prevention always beats firefighting: Correct storage, separation, isolation of suspect units and early action dramatically reduce incidents before they start. That’s the waste hierarchy mindset – prevention first.

Recycling Routes for Lithium Batteries

Moving a little further down the waste hierarchy now to recycling, there are options for lithium batteries. A common question we hear is “How much of a lithium battery can be recycled?”

There isn’t a single percentage for every battery, because chemistry, design and condition vary. But as a general rule of thumb:

  • Metals such as copper, aluminium, nickel and cobalt are routinely recovered.
  • Lithium recovery is increasing as UK/EU capacity grows.
  • Plastics and electrolytes may be partially recovered.
  • Lithium metal cells follow more specialised routes.

What matters is traceability. When batteries are consigned to authorised treatment, you can evidence recovery through completion certificates and downstream audit trails.

That raises another critical question…

Who’s Allowed to Recycle Lithium Batteries?

As per hazardous waste regulations, only authorised facilities can treat lithium batteries in the UK, and routes depend on whether the battery is standalone or embedded in WEEE equipment. Here’s an overview:

  • Standalone batteries: Approved Battery Treatment/Export Operators (ABTO/ABEO) handle sorting, discharge, disassembly and materials recovery.
  • Batteries in WEEE: Approved Authorised Treatment Facilities (AATFs) depollute the equipment first, then route batteries for specialist processing.
  • Interim/bulking transfer: Permitted hazardous waste transfer stations may consolidate and prepare consignments before final treatment.

It’s your responsibility to consign to licensed carriers and permitted sites, with the correct waste codes and ADR details. It’s your waste partner’s job to get it right, end-to-end, and keep your documentation audit-ready and compliant.

Chemical Spill Response Procedure: Are You Doing It Right?

There may be no use in crying over spilt milk, but spilt chemicals… that’s a different story altogether!

Imagine you’re halfway through another normal workday, and someone knocks over a container – as the smell of chemicals hits the air, the panic sets in. What happens now?

Read on as we walk you through a wealth of valuable information that will help you ensure you have a safe and effective chemical spill response procedure in place.

From the basics of containment and cleanup to procedures and spill kits, join us as we remove the guesswork so you’re prepared, not panicked when accidents happen.

  • What Is a Chemical Spill?
  • The Potential Impacts of a Chemical Spill
  • The Four Pillars of Chemical Spill Control
  • The Hierarchy of Chemical Spill Management
  • Who’s Responsible for Chemical Spill Cleanup?
  • Why Choose Hazport for Spill Response Support?

What Is a Chemical Spill?

A chemical spill is the accidental release of a potentially hazardous substance that poses a risk to people, property or the environment. Spills can happen during production, transport, storage, use or disposal, and they vary widely in severity.

Most likely, you can recall at least one occurrence of a chemical spill being reported in the news, but whether it’s a small splash of solvent in a lab or a major leak of industrial chemicals, every spill must be taken seriously.

What Is Chemical Spill Safety?

Chemical spill safety is all about being ready before something goes wrong. It means having the right procedures, training and equipment in place to prevent spills where possible – and to respond quickly and safely if and when they do happen.

It’s not just about cleaning up the mess – it’s about protecting your staff, your site, the public and the environment. Chemical spill safety includes:

  • Always storing chemicals properly.
  • Training staff to recognise and manage risks.
  • Ensuring your site is equipped to deal with accidents.
  • Having a straightforward, practised spill response procedure.

Getting this right is about much more than ticking a compliance box – it saves lives, prevents extensive damage, and keeps your business moving even when accidents happen.

The Potential Impacts of a Chemical Spill

Chemical spills aren’t just messy – they’re also dangerous. The impacts can be far-reaching and long-lasting, especially if the response is slow or mismanaged, as can happen when tackling a spill unprepared.

Here’s what’s at stake when a chemical spill happens:

  • Serious harm to health – Exposure to certain chemicals can lead to burns, breathing problems, or even long-term conditions like cancer. Some gases are toxic in tiny amounts. Others can ignite with the slightest spark.
  • Risk of fire or explosion – Flammable chemicals don’t need much encouragement to cause major incidents. Without fast containment, a small spill can quickly become a full-scale emergency.
  • Damage to property – Some chemicals can eat through flooring, corrode metals, or render entire rooms unsafe to use. In worst-case scenarios, fires caused by spills can bring down whole buildings.
  • Environmental fallout – Some chemicals can seep into soil, drains and nearby watercourses. This can destroy habitats, poison wildlife and lead to long-term contamination of land and water.
  • Costly disruption – Aside from the cleanup bill, spills often shut down operations, trigger investigations and delay projects – especially when you need emergency contractors to step in.
  • Regulatory consequences – If your spill affects the environment, or you fail to act fast enough, you could face enforcement action, fines or reputational damage that’s harder to clean up than the spill itself.

What’s the takeaway? Every minute counts. A well-prepared spill response can dramatically reduce the scale of the damage, eliminating the need to guess in the moment when action matters most.

So let’s dig into a chemical spill response procedure and see how you can handle such an incident.

The Four Pillars of Chemical Spill Control

The most effective response to a chemical spill is precisely that – a response, not a reaction. A fast, safe and compliant response hinges on four key pillars:

  • Spill prevention
  • Spill control and containment
  • Spill cleanup
  • Reporting and review

Let’s look at each pillar in a little more depth.

Pillar I: Spill Prevention

Many businesses focus on cleaning up, but real chemical spill safety starts before one happens. The most effective response is to prevent spills in the first place, eliminating the need for a response – however, accidents can and do happen.

This involves:

  • Storing chemicals and chemical waste securely and correctly.
  • Using secondary containment (like drip trays or bunds) when appropriate.
  • Conducting regular inspections and maintenance.

Need an audit? Hazport offers a full site audit to help you identify what’s working well and any gaps or areas for improvement.

Prevention may not feel like a ‘response’ in the typical sense of the word, but it’s your first and most effective line of defence.

Pillar II: Spill Control and Containment

If a spill occurs despite your best prevention efforts, the top priority is to contain it as quickly as possible to prevent spread and exposure. This is where your chemical spill kit comes in (always ensure your site is equipped).

As a rule of thumb, a chemical spill kit should contain:

  • Absorbent pads
  • Neutralisers (for acids/bases)
  • PPE
  • Disposal bags and labels
  • Instruction for use

Your team should also understand how to handle hazardous waste in an emergency, and be trained to follow your chemical spill response procedure, which includes:

  • Raising the alarm and assessing the risk*.
  • Putting on the appropriate PPE.
  • Stopping the source of the spill if safe to do so.
  • Containing the spill using absorbents, booms or barriers.
  • Ventilating the area if required.

Spill containment is critical – it buys time and reduces the risk of wider harm.

*When assessing the risk, producers need to understand exactly what has been spilt before anyone tackles the spill. Sometimes, more danger and harm can be created from tackling an unknown spill with the wrong method.

Pillar III: Spill Cleanup

Once the immediate risk is controlled, the chemical spill cleanup begins. This step must be carried out carefully to avoid exposure or secondary contamination. This involves:

  • Using appropriate absorbents or neutralisers.
  • Carefully collecting waste and contaminated materials.
  • Labelling and storing waste in line with hazardous waste regulations.
  • Arranging for compliant disposal via a licensed provider (like Hazport 😉).

In the cleanup stage, it’s crucial to get this right and avoid a dangerous cleanup on your own or without expert guidance.

Report spilled-Person on computerPillar IV: Report and Review

This is another critical stage and one that’s easily overlooked – we’re only human, so once the spill has been contained and cleaned up, it’s all over, right?

Wrong. After any chemical spill, you must:

  • Report what happened.
  • Review the root cause.
  • Check if your procedures or training need updating.
  • Refresh your risk assessments and COSHH documentation.

Hazport can assist with spill procedure training – from basic spills like oils to more complex spills such as aggressive chemicals.

If it’s a serious spill, you’ll also need to report it to the Environment Agency or HSE. Don’t bury the incident – use it to strengthen and inform your future preparedness.

The Hierarchy of Spill Management

The closer you stop it, the less damage it does.

Each spill has to be taken at face value, as does the way we deal with them, but in any case, the faster you act and the closer to the source you contain it, the better your outcome will be. Here’s a handy framework to help you prioritise the right actions, in the correct order.

#1 Contain at the Source

Best-case scenario

If you can stop a spill where it’s happening, this is the best option. It might mean turning off a valve, standing up a container, or sealing a leak, but you’ll be stopping damage before it begins.

Why it matters: It’s quicker, safer and cheaper to contain the spill right at the source.

#2 Contain Close to the Source

Next best thing

If you can’t stop it directly at the source, contain it as close as possible. Use absorbent socks (not the ones on your feet…), spill booms, or bunds to stop the spread. The aim here is speed and precision.

Why it matters: Containing the chemical close to the source limits how far it can travel, reducing cleanup time and risk.

#3 Contain on the Surface

Time to act fast

If the spill has started spreading, try to stop it from entering drains, cracks, or unsealed ground. This is where quick access to your spill kit makes a world of difference.

Why it matters: Surface-level spills are easier to control, but only if you act quickly.

#4 Contain in the Drainage System

The danger zone

If the spill has made it into your drains, your priority is  to stop it from going any further. Use drain covers, mats, or inflatable bungs if trained (you, not the bungs…). This is a critical moment to prevent environmental harm.

Why it matters: Spills in drains can travel quickly and widely, leading to regulatory consequences.

#5 Contain on or in a Watercourse

The danger zone

If the chemical reaches a river, stream or surface water, containment is still possible, but your options are limited, and the risks are high. You must notify the Environment Agency immediately and bring in specialist help.

Why it matters: At this stage, you’re no longer just cleaning up – you’re protecting public health and ecosystems.

As noted earlier in this blog, the best spill response is prevention. But the second best is having a prepared response before the damage spreads. This hierarchy can help to guide your actions when every second counts.

Who’s Responsible for Chemical Spill Cleanup?

Ultimately, the responsibility for a chemical spill lies with you, the waste producer. Under the UK hazardous waste laws and regulations, you’re required to ensure that any spill is managed safely and that the resulting waste is classified, labelled and disposed of properly.

Even once the waste has left your site, you’re still legally accountable for what happens with it. That’s why having a clear plan and a competent waste partner is so important.

Waste Duty of Care Explained for Hazardous Waste Producers

Whose problem is it when your waste leaves your premises? Funnily enough (or perhaps not), it’s still yours…

If your business produces hazardous waste, you have legal responsibilities that go beyond simply arranging for someone to collect it. This falls under your Waste Duty of Care – a legal requirement that applies to every business handling waste in the UK.

But what exactly is a Duty of Care? What does it mean in practical terms? How can you make sure your business is doing the right thing? Read on to see your Waste Duty of Care explained as we remove the guesswork.

  • What Is the Waste Duty of Care?
  • Who Does the Waste Duty of Care Apply To?
  • How Does the Waste Duty of Care Work?
  • How Long Does Your Waste Duty of Care Last?
  • What Is a Waste Duty of Care Audit?
  • Ensure Duty of Care with Reliable Waste Support

What Is the Waste Duty of Care

The Waste Duty of Care is a legal obligation requiring anyone who produces, carries, keeps, treats or disposes of waste to take all reasonable steps to ensure their waste is managed safely and legally from production through to final disposal. It means you’re responsible for your waste from the moment it’s produced until it’s dealt with. That responsibility doesn’t even end when the waste leaves your site – if something goes wrong further down the line and your business didn’t follow the proper process, you could still be held accountable.

This legal obligation is set out in Section 34 of the Environmental Protection Act 1990 – a fact that, if remembered, sounds either very impressive or super nerdy, depending on the company you keep…

The idea behind the Waste Duty of Care is to prevent waste from being mismanaged and causing harm to the environment or public health.

The Waste Duty of Care Code of Practice

The Waste Duty of Care Code of Practice provides further practical guidance for complying with the law. This code, issued by the Department for Environment, Food & Rural Affairs (DEFRA), is admissible in court and offers clear steps to ensure waste is managed the right way.

Why Is It Important?

To begin with, there’s the ethical side of things – hazardous waste can pose serious risks to people, wildlife, ecosystems and the environment. Managing waste properly isn’t just about ticking boxes – it’s about doing the right thing morally. This alone should be enough, but we’ve seen enough fly-tipping and illegal waste disposal to know it isn’t.

Failing to meet your Duty of Care can have serious consequences, such as hefty fines (there’s no upper limit on the courts’ power to fine), legal action, and lasting damage to your business’s reputation.

Who Does the Waste Duty of Care Apply To?

Do you come into contact with waste as part of your day-to-day? Chances are, the Duty of Care applies to you, even if you only produce small amounts of waste.

Duty of Care waste legislation in the UK applies to anyone who:

  • Produces waste – all business types, including private sector businesses such as manufacturers, labs, construction firms, and public sector services like schools, medical facilities and prisons. Waste producers are the best-suited people in the waste journey to identify and classify the waste.
  • Carries or transports waste – any person who regularly collects, carries or transports waste as part of day-to-day business or as a profitable endeavour (including your own waste).
  • Deals in or brokers waste on behalf of others – anyone who buys waste (yes, it’s a thing!) with the intention of selling it on, even if they don’t take physical possession of the waste themselves. This also includes those who arrange waste management and transportation on behalf of others.
  • Stores or treats waste on-site – this could cover those producing waste in the first place, right through to whoever is responsible for its final disposal.

If you fall into one of the above categories, you are what the Waste Duty of Care Code refers to as a ‘waste holder’.

How Does Waste Duty of Care Work?

There are a few essential steps for a hazardous waste producer to understand as part of the Duty of Care requirements:

#1 Classify Your Waste Correctly

You must accurately identify and label hazardous waste using the correct hazard property codes and descriptions. This helps ensure the waste is handled safely and legally throughout the full journey. Unsure of your waste? A mobile chemist will be able to help you identify, classify, label and pack your waste if needed.

 

#2 Store Your Waste Safely

Hazardous waste must be stored securely in UN-approved containers that are appropriate for the type of waste. The containers need to be clearly labelled and stored in a way that prevents leaks or spills.

#3 Only Use Licensed Waste Carriers

You must only hand over hazardous waste to a carrier who is licensed to transport it – this means doing our due diligence and checking their waste carrier registration. There are plenty of cases of companies prosecuted for handing hazardous waste over to unlicensed operators who went on to dump it illegally.

#4 Understand Waste Transfer and Consignment Notes

A waste transfer note must accompany every movement of non-hazardous waste. For hazardous waste, a hazardous waste consignment note is used for tracking the waste movement. These documents prove that waste has been transported legally and responsibly.

#5 Keep Records

You need to keep copies of all of your waste transfer and hazardous waste consignment notes, as well as any other relevant documents. This help prove that you’ve met your obligations, should any questions arise or a Waste Duty of Care Audit be needed.

How Long Does Your Waste Duty of Care Last?

Gone are the days of throwing something away and never giving it a second thought… Your Duty of Care doesn’t even end when waste leaves your premises. It continues until the waste has reached its final, legal destination – whether that’s a recycling facility, a treatment plant, or a licensed disposal site.

To meet your ongoing responsibility, you’re expected to take reasonable steps to make sure your waste isn’t mishandled at any stage of the journey. This isn’t just good business practice – it’s your legal obligation under the Waste Duty of Care Code of Practice.

Failing to follow the requirements can expose yourself and your business to criminal prosecution, fines, and reputational damage – even if you use a broker or dealer, you still share responsibility for what happens to your waste.

In short, your duty of care continues until the waste is fully recovered or disposed of – not just until it’s collected.

In terms of how long you should keep waste transfer notes and hazardous waste consignment notes – whether electronic or paper:

  • Two years for non-hazardous waste
  • Three years for hazardous waste

What Is a Waste Duty of Care Audit?

A Waste Duty of Care audit is a review of your business’s waste management practices to ensure you’re fully compliant with legislation. It typically looks at:

  • Waste classification procedures
  • On-site storage methods
  • Paperwork (including transfer and consignment notes)
  • Whether your waste contractors are properly licensed

Carrying out regular audits can help you spot gaps, find opportunities and stay audit-ready ahead of any surprise inspections.

What Is Pharmaceutical Waste?

Pharmaceutical contaminated water

Join us as we dig into everything pharmaceutical waste, from hands-free egg yolk extraction to how many UK rivers contain fish with drug dependencies – and everything in between.

If you’re a pharmaceutical manufacturer, chances are you’re already familiar with this waste type, but does everyone on your team share the same knowledge? Does your waste service provider also understand the complexities?

  • What Is Pharmaceutical Waste?
  • A Note to Pharmaceutical Manufacturers
  • Key Types of Pharmaceutical Waste in Manufacturing
  • Is Pharmaceutical Waste Always Hazardous?
  • How Can Hazport’s Mobile Chemists Best Serve You?
  • What Are the Legal Regulations for Pharmaceutical Waste?
  • A Study on the Environmental Impact of Pharmaceutical Waste
  • The Role of a Licensed Pharmaceutical Waste Management Partner
  • Hazport: Your Partner in Safe, Secure and Compliant Pharmaceutical Waste Management

What Is Pharmaceutical Waste?

Pharmaceutical waste refers to any discarded material that originates from the production, handling or testing of pharmaceutical products. For manufacturers, this can include everything from expired raw materials and off-spec batches to residues, contaminated equipment and PPE, as well as process wash water.

If your business is involved in the production, packaging or testing of any pharmaceutical products, then you’re certain to be creating pharmaceutical waste.

A Note to Pharmaceutical Manufacturers

We’re not here to teach your grandmothers how to suck eggs – we know that if you’re manufacturing pharmaceuticals, you’re already well-versed in the materials you’re handling and their inherent hazards. You’re working with tightly controlled substances, you most likely have robust quality systems and understand the importance of classification, segregation and compliance.

But even in the most experienced teams, mistakes can happen – especially when it comes to waste. After all, how often do you think about an item after you’ve binned it?

Mislabelled containers, cross-contaminated waste streams and missed regulatory changes are challenges we see a lot of UK pharmaceutical manufacturers facing, and even if your team makes zero mistakes, you also need a pharmaceutical waste service provider who understands pharmaceuticals as well as you do – someone who speaks your language and knows what’s at stake.

Key Types of Pharmaceutical Waste in Manufacturing

Some of the most common types of waste produced in pharmaceutical manufacturing facilities include:

#1 Production Waste

  • Off-spec or contaminated batches
  • Residual powders or liquids from mixing tanks
  • Expired pharmaceuticals or ingredients
  • Leftover raw materials and active pharmaceutical ingredients (APIs)

#2 Solvent and Chemical Waste

  • Used solvents such as ethanol, methanol and acetone
  • Cleaning fluids and reagents
  • PH-adjusting chemicals such as hydrochloric acid, acetic acid and sodium hydroxide
  • Alcohol based hand gels

#3 Contaminated Materials

  • Packaging or items that have been in contact with pharmaceuticals
  • PPE such as gloves, aprons and goggles
  • Cleaning cloths or wipes
  • Filters and swabs
  • Used glass vials or syringes

#4 Cytotoxic and Cytostatic Waste

  • Associated with chemotherapy or hormone-based drug manufacturing

#5 Laboratory Waste

  • Analytical test samples
  • Expired reference standards
  • Calibration residues and assay chemicals

And to think, this list is non-exhaustive! Each waste type may need a different approach to storage, handling and disposal, depending on its classification.

Is Pharmaceutical Waste Always Hazardous?

No, not all pharmaceutical waste is hazardous. When you consider the definition of hazardous waste – if it or the material or substances it contains are harmful to humans or the environment – it makes it easier to separate hazardous pharmaceutical waste from non-hazardous:

  • Hazardous Pharmaceutical Waste includes materials that are toxic, flammable, corrosive, or reactive. Examples include cytotoxic/cytostatic drugs, certain antibiotics, lab chemicals and controlled substances.
  • Non-Hazardous Pharmaceutical Waste includes materials that don’t meet the criteria for hazardous waste but still require proper disposal. Examples include over-the-counter medications and some prescription drugs.

To be sure what’s hazardous and what isn’t, professional classification is essential. This is where Hazport’s Mobile Chemists can prove helpful.

How Can Hazport’s Mobile Chemists Best Serve You?

Our Mobile Chemists aren’t just experts in hazardous waste; they also bring a deep familiarity with pharmaceutical processes, regulatory requirements, and site-level practicalities. They also turn up in pretty cool Hazport-branded vehicles, but that’s going off-topic…

Here’s how our mobile chemists support pharmaceutical manufacturers:

  • Identification: We assess your waste on-site using safety data sheets, production data and visual inspection to identify its composition and risk profile.
  • Classification: We assign the correct EWC codes and hazard properties based on UK regulations.
  • Labelling: We provide compliant labelling that clearly displays the waste type, hazard symbols and relevant regulatory references.
  • Packing: We ensure waste is safely and securely packed in UN-approved containers for safe storage and transport.

Our mobile chemists are also available to train your team, conduct waste audits and support the implementation of internal waste segregation systems – removing the guesswork from pharmaceutical waste management.

Get in touch if you need support with classifying your pharmaceutical waste.

What Are the Legal Regulations for Pharmaceutical Waste?

Pharmaceutical waste management in the UK is governed by several vital regulations, which are crucial to understand to maintain compliance:

Visit our compliance page for information on other hazardous waste regulations, or for fun, if it’s the kind of thing you enjoy.

A Study on the Environmental Impact of Pharmaceutical Waste

Alarming levels of pharmaceutical pollution were revealed by a 2024 study by the University of York and the Rivers Trust, which found pharmaceutical pollution in 52 out of 54 river sites across all 10 of England’s national parks.

This pollution poses a serious threat to ecosystems – not only bad news for a significant number of fish that may end up hooked (pun intended), but also harming the lesser thought about organisms like invertebrates and algae.

Due to their low flow and outdated treatment facilities, rural river systems tend to be more vulnerable as the dilution of contaminants becomes difficult. For pharmaceutical manufacturers, this highlights the crucial importance of responsible waste management practices – not only for compliance, but also for safeguarding environmental and public health.

The Role of a Licensed Pharmaceutical Waste Management Partner

Outsourcing your pharmaceutical waste management to a specialist like Hazport doesn’t just simplify compliance – it protects your business through:

  • Fully traceable waste, from collection to final disposal.
  • Waste documentation and consignment note management.
  • Access to a team of experts who know pharmaceutical waste inside out.
  • Emergency response and spill containment if needed.
  • Advice on waste minimisation and segregation.

Rethinking Hazardous Waste in Shropshire’s Industrial Growth

In industrial Shropshire, managing waste isn’t just a task on your to-do list – it’s a liability if you get it wrong.

From the rolling countryside of Oswestry to the industrial estates of Telford, Shropshire is quietly powering some of the UK’s most vital sectors. Food producers, engineering firms, and agri-tech innovators all call this county home, and their output is growing. But with growth comes complexity. And one area that often goes overlooked until it becomes a problem is (drum roll please…) hazardous waste.

If your business is producing, handling, or storing hazardous materials – whether it’s solvents, oils, contaminated packaging, or chemicals – you’re carrying more risk than you might think. The good news is that with the right approach and a partner you can rely on, managing that risk doesn’t have to be difficult.

Growth Across Shropshire Means New Waste Challenges

Industrial Growth-process-Hazardous-wasteShropshire has come a long way from being known only as rural farmland and market towns, and it’s still living up to its reputation of being the birthplace of the industrial revolution. In fact, the region is seeing steady growth in several key industrial sectors, particularly:

  • Advanced manufacturing in Telford and Shrewsbury
  • Food and drink production across Bridgnorth and Ludlow
  • Engineering and fabrication throughout central and northern Shropshire
  • Agri-tech and life sciences emerging in Oswestry and surrounding areas

As well as driving the local economy and transforming Shropshire, these businesses are also generating increasingly diverse and complex waste streams, many of which are classified as hazardous under UK law.

From IBCs of spent oils to contaminated PPE and out of date chemical stock, the reality is that more businesses in Shropshire are producing hazardous waste – many still don’t realise the full extent of their responsibilities.

Hazardous Waste: A Legal and Operational Risk

Navigating hazardous waste regulations can often be daunting, especially when the stakes are high. As a hazardous waste producer, you have a clear set of responsibilities:

  • You must correctly classify and separate your hazardous waste.
  • You must store it securely and safely.
  • You must use a licensed carrier and disposal facility.
  • You must keep consignment notes and records for at least three years.

It doesn’t make a difference whether you’re a small food producer near Ludlow or a machining workshop in Whitchurch – these responsibilities apply.

And the consequences of getting hazardous waste wrong? Fines, reputational damage, environmental harm – or worse, injury and prosecution.

The Mistakes We See Most in Shropshire

We’ve been operating in the area for almost two decades, and having worked across the county for so long, we’ve come to recognise some common missteps that can lead to unnecessary risk.

Underestimating Small-Scale Waste

Do you know what we hear often? ‘Wow, you got here fast—’ oops, wrong quote… ‘We don’t produce much hazardous waste.’ However, even a single container of flammable solvent, incorrectly stored or handled, or chemically contaminated packaging that remains on your site, can put staff and property at risk. It can also land your business in hot water with the Environment Agency, and they drink hot water for breakfast.

Mixing Incompatible Materials

One bin for everything might seem efficient on paper, until you mix acids with alkalis, batteries with aerosols, or oil-soaked rags with general waste. It’s dangerous, non-compliant, and potentially explosive.

Poor Documentation

Many businesses fail to hang on to their hazardous waste consignment notes for long enough, or they rely on third-party carriers who fail to provide them. Unfortunately, it’s still your legal responsibility to demonstrate proper handling and disposal of hazardous waste. As noted earlier, even small volumes of solvents or chemicals can pose major risks if not handled according to COSHH and hazardous substance guidance.

What Forward-Thinking Businesses in Shropshire Are Doing Differently

In contrast to some of the mistakes we’ve seen, we’ve also seen a number of proactive businesses we work with across Shropshire taking a smarter approach to hazardous waste management.

Conducting Waste Audits

From food plants to engineering works, the best operators regularly review their waste streams, not just for compliance with Shropshire Council’s permitted industrial processes, but also to reduce costs and improve efficiency.

Training Staff Properly

Your compliance is only as strong as your team’s understanding. Businesses that invest in short, practical training that’s been tailored to their specific operations face fewer incidents, less confusion, and more confident handling.

Partnering with Specialists

Generic waste carriers often miss the mark when it comes to hazardous materials – if it’s not their main area of focus, it’s not a priority. The most successful firms we see choose partners who:

  • Know the area and respond quickly.
  • Understand their sector-specific waste.
  • Have mobile chemists available to help classify and package waste.
  • Provide full documentation and guidance, not just waste collections.

Why Local Knowledge Makes the Difference

At Hazport, we’ve supported businesses across Shropshire for almost two decades – from Telford’s industrial zones to rural depots near Oswestry. We know the county’s infrastructure, access issues, and local regulatory expectations.

Whether it’s:

  • Weekly collections for oil drums in Bridgnorth,
  • Lab packing for chemical stores in Shrewsbury, or
  • Emergency response to a spill on a remote farm site near Market Drayton

We remove the guesswork and bring experience, clarity and speed to every job.

Whilst Hazport can handle and dispose of any hazardous waste produced by businesses and commercial enterprises required to use licensed carriers, we can’t collect household waste.

For hazardous household waste – please handle with care and do not dispose of it with your general waste. Shropshire Council advises taking it to your nearest household recycling centre instead.

It’s Not Just About Disposal – It’s About Reputation

With the UK Government aiming to achieve Net Zero by 2050 and shifting workplace priorities, more and more businesses are being asked to prove their Environmental, Social, and Governance (ESG) credentials.

Hazardous waste management is one of the clearest indicators of how seriously you take your environmental responsibilities – you don’t want to be known as the restaurant pouring oil down the drains out back, or the fly tipping construction company after all.

  • Can you show how much hazardous waste you’ve generated this year?
  • Do you have plans in place to reduce the amount of hazardous waste you produce?
  • Can you demonstrate how it was handled and where it went?
  • Can you prove your provider is licensed and compliant?

If not, you’ve got a blind spot, and that blind spot could be costly. If you can’t demonstrate how your waste has been classified in line with the WM3 Waste Classification Guidance, you may fall short of audit expectations.

Waste Shouldn’t Be the Weak Link

Compliant hazardous waste management isn’t a box to tick – it’s a large part of your operational footprint. And as Shropshire continues to grow its industrial profile, the pressure to get it right is increasing.

The best time to get on top of your hazardous waste management was yesterday. The second-best time is right now.
