Hazardous Waste Management

With Ashland County government and in partnership with the Northwest Regional Planning Commission the Extension Ashland County office coordinates an annual hazardous waste collection called ‘Clean Sweep.’  Collections are held in the summer, for more information see the 2020 Hazardous Waste Collection Event post.

The Ashland County Collection was Wednesday, August 12, 2020 from 2-7pm at WITC – Ashland Campus south parking lot.

We have also compiled and update annually a booklet on where you can properly dispose of various hazardous materials during the year.  Here is the latest edition: Household Hazardous Waste Disposal Guide 2020

Counties in Northern Wisconsin have contracted with the Northwest Regional Planning Commission to offer annual Cleansweep Collections at no or low cost to households, farms, and businesses in a nine-county region since 1995. The program received a Wisconsin Governors Award for Excellence in Solid Waste Reduction by offering almost 400 collection events and keeping 1.6 million pounds of toxic materials from harming our waters, land, and wildlife.

An annual Cleansweeps hazardous material collection event allows residents, like this Ashland County participant in 2018, to safely dispose of toxic products such as lawn and garden chemicals, household cleaners, and medications. Farmers and small quantity business generators can also participate in the event.
