What is Hazardous Waste?
Hazardous waste is any material that can harm human health or the environment. In the UK, waste is classed as hazardous if it exhibits one or more of the following characteristics:
- Toxic
- Corrosive
- Flammable
- Reactive
Some common examples include:
- Asbestos
- Solvents and paints
- Batteries
- Cleaning products
- Pesticides
- Industrial chemicals
Businesses that produce hazardous waste have a duty of care under the Hazardous Waste Regulations (2005) and must store, handle and dispose of properly. For many, partnering with a licensed waste management company like Remondis UK is the most efficient and compliant way.
What are the Four Types of Hazardous Substances?
Hazardous substances are generally categorised into four groups:
- Chemical Waste: Solvents, acids, alkalis, contaminated rags or containers.
- Biological Waste: Medical or laboratory waste; sharps, infected materials or samples.
- Radiological Waste: Specialist industries, radioactive materials.
- Physical Waste: Sharp items or pressurised containers like aerosols.
Knowing what type of hazardous waste you have will help you determine the best disposal method.
How to Dispose of Hazardous Waste
There is no one size fits all. The disposal method depends on the waste:
- Incineration: Organic hazardous waste, incineration reduces volume and destroys toxins.
- Landfill (with specialist cells): Some waste like asbestos must be double bagged and sent to licensed hazardous landfill sites.
- Neutralisation: Used for chemical waste, where acids or bases are treated to reduce reactivity.
- Encapsulation: Some solid hazardous waste is sealed in containers and buried.
- Recycling or Recovery: Certain solvents, oils and metals can be treated and reused.
Remondis UK offers bespoke hazardous waste collection and treatment solutions, with full compliance and traceability.
How to Dispose of Hazardous Waste in the Workplace
Businesses must follow these protocols:
- Identify and label all hazardous waste correctly.
- Store securely in suitable, clearly marked containers.
- Segregate incompatible materials to prevent reactions.
- Keep records (consignment note) for all movements of hazardous waste.
- Use a licensed waste carrier like Remondis.
Workplaces also need a waste management plan to ensure staff are trained and procedures are in place. If you’re not sure where to start, Remondis offers full workplace waste audits and bespoke hazardous waste collection services.
How to Store and Dispose of Hazardous Chemical Waste
Proper storage is key to prevent spills, accidents and environmental harm.
- Use leak-proof, compatible containers with tamper-proof lids.
- Clearly label with substance name, hazard class and date.
- Keep an inventory of all chemicals on site.
- Store separately from general waste or incompatible materials.
When ready to dispose:
- Contact a licensed hazardous waste contractor (Remondis).
- Complete a consignment note (required by law).
- Ensure safe collection and transport to an authorised facility.
Businesses that produce even small amounts of hazardous chemicals should not delay disposal, as improper storage increases risk and liability.

How to Dispose of Household Hazardous Waste
While businesses have stricter rules to follow, households also need to be careful. Common household hazardous waste includes:
- Old paint and varnish
- Cleaning chemicals
- Car batteries
- Weedkillers or pesticides
Follow these steps:
- Don’t pour it down the drain or put it in your black bin.
- Take it to your local household waste recycling centre (HWRC). Most centres have a hazardous waste drop-off point.
- Check with your council as rules may vary. Some materials need to be pre-booked or handled specially.
- Use manufacturer take-back schemes for items like batteries or electronics.
If you’re clearing a property or dealing with larger volumes, Remondis can help with skip hire for specialist waste, including hazardous material handling.
How to Dispose of Paint
Paint is one of the most common, yet misunderstood, forms of household hazardous waste.
- Water-based paint (emulsion): Once dry, it can go in the general waste.
- Solvent-based paint (oil-based or gloss): Must be treated as hazardous waste.
Tips:
- Use up leftover paint or donate it.
- Dry out emulsion paint using cat litter or sawdust if disposing of it.
- Take solvent-based paint to your local HWRC or contact a waste contractor.
Remondis offers collection services for paint and solvents as part of its hazardous waste portfolio, perfect for businesses in construction, painting and decorating industries.
