Safe Waste Disposal
The Household Hazardous Waste (HHW) Program provided by San Mateo County helps residents dispose of/recycle their residential hazardous waste properly – for FREE! County residents may drop off a full range of HHW at collection facilities and events year-round every Thursday, Friday, and Saturday (except major holiday weekends).
All waste collected is either reused, recycled, processed for energy recovery, or stabilized for proper disposal to achieve zero waste being landfilled.
San Mateo County now has over 50 medicine disposal locations available for residents to dispose of medicine safely. By taking your unwanted or expired medicine to one of the convenient kiosks listed below, you are protecting the environment, preventing overdoses and errors, and helping keep drugs away from kids and teens.
There are two easy and free options to safely dispose of your used motor oil and filters together.
