It is illegal to put items such as electronics, fluorescent bulbs and tubes, paints, pesticides, cleaning products and expired medicines into the garbage or down a drain or gutter.

Electronic Waste (E-Waste)

Electronic WasteE-waste contains a variety of toxic components like lead, cadmium and mercury. When dumped in a landfill, these materials can contaminate the soil and ground water, thus impacting surrounding areas. Computers, monitors, printers, laptops, TVs, VCRs, DVD players, and stereos are types of e-waste that do not belong in any of your three carts or bins.

The Shoreway Public Recycling Center accepts e-waste at no cost.


Select retailers take back used or oil latex and oil-based paint at no charge through the PaintCare Program. PaintCare is an industry funded paint stewardship program where residents can drop off paint at numerous paint locations in San Mateo County.

Visit for more program information, what is accepted and current list of drop-off locations.


When unused or expired medicines are disposed of in the trash or down the drain or end up in the wrong hands, they can harm our soil and local waterways. This is why in 2015, San Mateo County Board of Supervisors passed the Safe Medicine Disposal Ordinance requiring medicine manufacturers to design, develop and fund a medicine collection program.

There are now over 50 locations in San Mateo County that accept unwanted and expired medicines, including local pharmacies and police stations. Visit Med-Project to find locations near you.
