MMSD Will Take Your Hazardous Waste For Free (2021)

It’s the time of year when many of us are fall cleaning at home, but sometimes you may encounter chemicals and items that you don’t know what to do with.

If you have old painting supplies, weed killer, pools chemicals, and other hazardous materials in your home, the Milwaukee Metropolitan Sewage District will take if off your hands for free.

Bringing your unused household chemicals to MMSD’s Home HazMat Collection Program helps protect our drinking water, too.

The drop-offs are free and easy to use for Milwaukee County residents. You don’t even have to get out of your car.

There’s a full list of things they accept and those they do not accept at
