How should I dispose of hazardous waste?
Household hazardous wastes (HHW) are products that contain toxic materials that can be harmful to humans and the environment if disposed of improperly. Hazardous waste is not accepted in curbside garbage, recycling, or organics carts. Look for a label that may say CAUTION-WARNING-DANGER-POISON to determine if a product is hazardous. Empty containers may go in the garbage, with the exception of propane tanks.
Household hazardous waste items include, but are not limited to: toxic household cleaners, paint thinners, pesticides, mercury-containing fluorescent bulbs and tubes, electronic waste and car batteries.
