Clean Sweep is a special event hazardous waste collection program that is hosted by our municipal partners within select communities.

Our next Clean Sweep event will be held on Monday April 24, 2023. You may also visit our seasonal hazardous waste facility in Oshkosh on select days May - October.

Ag & Household Hazardous Material Disposal

When disposed of improperly, ag and household hazardous materials have potential to threaten the quality of our environment and the safety of sanitation workers, as well as pose an accidental poison risk to children and pets. The Winnebago County Clean Sweep provides free hazardous material disposal services to in-county farms and households.  


Materials accepted by appointment only.

Business Hazardous Material Disposal

Hazardous materials will also be accepted from Winnebago County businesses identified as Very Small Quantity Generators (VSQG) during these collection events.  Disposal fees apply to business materials.  Eligible businesses may receive a 50 percent subsidy for disposal of pesticide wastes. 


Materials accepted by appointment only.

Donations Accepted

This program is funded by Winnebago County Solid Waste and by grant funds provided by Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).  Monetary donations will be accepted during the event to help offset disposal and program costs.
