Household Hazardous Waste Collection Facility

Many products found in your home are potentially hazardous substances. They consist of chemical compounds that can poison, corrode, explode or ignite when not handled properly. These substances are considered household hazardous waste (HHW) and can threaten human and environmental health. For this reason, HHW is not exempt from California hazardous waste laws. It is illegal to dispose of HHW in the trash or down household and storm drains. The Household Hazardous Waste collection facility gives local residents and small businesses a convenient and environmentally safe means for HHW disposal and recycling.

Located at 4797 Imhoff Place, Martinez, CA 94553-4392
