Hazardous waste disposal for business: what counts and how to do it right

Hazardous waste sounds like something only factories deal with, but plenty of everyday businesses produce it. Getting its disposal right matters — both for safety and because it's tightly regulated.

What counts as hazardous waste

Hazardous waste is anything that could harm human health or the environment. Common business examples include:

• Chemicals, solvents and certain cleaning products
• Batteries (including vehicle and industrial batteries)
• Fluorescent tubes and energy-saving bulbs
• Many electrical items (WEEE) — old IT equipment, appliances
• Oils, some paints and aerosols

Why it can't go in normal bins

Hazardous waste can't go in your general or recycling collection. It must be stored safely, kept separate, and collected by a licensed carrier for specialist treatment. Putting it in ordinary waste is unsafe and unlawful.

The paperwork: a consignment note

Unlike ordinary waste (which needs a waste transfer note), hazardous waste requires a consignment note, which you must keep for at least three years. This is part of your duty of care, and a good provider produces it for you.

Who produces it (more than you'd think)

Offices (old IT and batteries), shops, garages, salons and workshops all commonly produce some hazardous waste. If your business uses chemicals, replaces light tubes or disposes of electricals, this applies to you.

The rule of thumb: if it could harm someone or pollute, it's not general waste. Identify what hazardous waste you produce, use a licensed carrier, keep the consignment notes, and you'll be safe and compliant.
