The Dubuque Metropolitan Area Solid Waste Agency (DMASWA) accepts household hazardous wastes (HHW) such as oil-based paint, motor oil, lawn chemicals, and other chemicals through the winter season. HHW’s pose an environmental and human health risk if not managed properly. These materials should be brought to the Dubuque Metropolitan Area Solid Waste Agency (DMASWA) Regional Collection Center (RCC) for safe disposal and should not be disposed of in trash cans, floor drains, or storm sewers.
This service is FREE to Dubuque and Delaware county households. From November through March, materials can be dropped off anytime between 7:30 a.m. and 3:30 p.m. Tuesdays, Thursdays, or Saturdays. No appointments are needed for residential customers. Any businesses requiring hazardous waste disposal assistance may contact the RCC. The RCC is located at the Dubuque Metro Landfill along U.S. Highway 20 on Dubuque’s west side. For more information, go to https://www.dmaswa.org/services/hazardous-materials/ or call (563) 557-8220.
