Residential hazardous waste can injure waste collectors, and can damage the environment if disposed of improperly. Household hazardous waste must not be put in the garbage or poured down the drain. Each year the Household Hazardous Waste Depot recycles or properly disposes over 800,000 litres of residential hazardous waste.
Residential hazardous waste is usually labeled as corrosive, explosive, poison or flammable:
Instead, residential hazardous waste can be taken to the Household Hazardous Waste Depot located at the Halton Waste Management Site, 5400 Regional Road 25, Milton (view map

There is a 20 litre maximum per visit. No commercial hazardous waste can be accepted.
Empty paint cans (dry with lids removed) and other empty containers (with no liquid or powder residue) can be disposed of with regular garbage.

Why bring Household Hazardous Waste to Halton's HHW Depot?
Products that consumers buy and use everyday can be safe when used properly and the manufacturer's instructions are followed; however, when not disposed of properly, these same products can become harmful to people, animals and the environment.
So please remember...
- Hazardous products can and do mix when placed in the garbage truck. Just like the home, the mixing of chemicals can cause adverse reactions and this can lead to injuries to the people who collect your waste. For the safety of others, please ensure that these materials never make it into the truck!
- Hazardous products must not be landfilled at the Halton Waste Management Site.
- Household Hazardous Waste can result in the pollution of soil, ground water, rivers and lakes when disposed of improperly.
- Do not dispose of needles, lancets and syringes in your garbage, Blue Box, GreenCart, or yard waste. It is illegal and dangerous.
