Household Hazardous Waste

Household hazardous waste (HHW) is any hazardous waste generated from owning or maintaining a residence. It includes paints, solvents, varnishes, acids, flammables, acrylics, and resins. The most safest and most convenient way for Union City residents to properly dispose of HHW is to take them to a certified HHW drop-off facility.
