What Is Chemical Waste?

What comes to your mind when you hear the term ‘chemical waste’? Hopefully, it’s not ‘What is chemical waste?’

But if it is, we’ve got you covered…

Read on as we remove the guesswork and define exactly what chemical waste is along with some examples and tips for handling it safely and in compliance with regulations.

What Is Chemical Waste?

Chemical waste refers to any discarded material that either contains dangerous chemicals or has come into contact with them. This material can exist in various forms – solid, liquid, or gaseous – and may pose risks to human and environmental health.

Examples of chemical waste range from substances with apparent hazards such as acids and pesticides, to seemingly safer but still potentially risky materials like cleaning products and paint.

So that’s the definition covered, but what about specific types of chemical waste? You might find some of them surprising…

Examples of Chemical Waste

A variety of chemical waste can be either hazardous or non-hazardous, and this type of waste isn’t limited to laboratories either – you can find chemical waste in everyday settings such as automotive garages and offices.

Whether you’re a lab technician, gardener, cleaner or you work in an administrative role, there’s a high probability you’ll come into contact with some form of chemical waste at some point in your working day – understanding what classifies as chemical waste is crucial for ensuring all waste is appropriately segregated before disposal.

Common types of chemical wastes include:

  • Batteries ranging from household ones to car and machinery batteries.
  • Chemical containers or packaging contaminated due to contact with chemicals.
  • Cleaning products like detergents, disinfectants, and sprays.
  • Fluorescent light bulbs containing argon, xenon, neon, and mercury vapour.
  • Paints such as emulsion, gloss, primer, etc.
  • Printer toner and ink cartridges including empty ink cartridges considered contaminated by contact with chemicals.
  • Pesticides such as insecticides, fungicides, herbicides, and biocides.
  • Solvents like acetone, ethanol, methanol.
  • Waste oils including diesel, kerosene, gearbox oil and other types.
  • Waste Electrical and Electronic Equipment (WEEE) products and their internal components.
  • Used aerosol cans such as deodorants, air fresheners, and more.

Where Does Chemical Waste Go?

For a long time, the norm was for companies to send their chemical waste to landfill. The biggest problem with that methodology is the environmental damage it can cause, risking leaks into the surrounding ground or water and causing pollution.

Nowadays, however, there are alternative methods available for chemical waste disposal, depending on the type of chemicals involved, these include:

  • Reclamation: This involves removing and recycling chemical waste products like mercury from items such as broken thermometers.
  • Dewatering: This method is suitable for oil waste, separating the oil from water for proper disposal.
  • Filtering and distilling: Filtering eliminates additives or inorganic materials, whilst distilling refines oil through boiling. Both processes enable the reuse of oil in some capacity.
  • Chemical treatments: Certain types of chemical waste, such as sulphuric or hydrochloric acids can be repurposed after undergoing specific chemical treatments.
  • Thermal treatments: Applying heat helps sanitise waste products, ensuring the safe and secure disposal of chemical waste.

What’s The Safest Way to Store Chemical Waste?

Regardless of whether the waste is classified as hazardous or non-hazardous, it’s crucial to manage, store, and dispose of chemical waste securely and in accordance with safety guidelines.

To ensure compliance with chemical waste disposal regulations and safe storage within your facility before collection, it’s essential to adhere to the following guidelines:

  • Exercise caution and care in handling chemical waste and/or products both before, during, and after use.
  • Any person interacting with chemical waste and/or products must wear appropriate personal protective equipment (PPE) and adhere to health and safety protocols.
  • Store chemical waste at a designated location within your facility, inaccessible to the general public, such as a locked or concealed area.
  • Ensure the separation of chemical wastes from other hazardous materials and place them in appropriate chemical waste bins and containers. Regularly inspect these containers to confirm they remain undamaged.

Doing so will keep you compliant with government chemical waste disposal regulations such as the Control of Substances Hazardous to Health (COSHH).
