There are several electronics recycling centers in San Mateo County. If the item is under 5 years old, it can often be donated to an electronics refurbishing/reuse program. For practical purposes, in terms of current regulations, it is illegal to throw out practically all electronics. Our database will show where to recycle (or donate) electronics; use search categories of Electronics and Computer Equipment.
In July 1st, 2006 two new waste recycling laws, AB 1125 and AB 2091, went into effect, requiring retailers to take back rechargeable batteries and cell phones for recycling. This legislation creates convenience and incentives for consumers: it's easy to drop off and recycle end-of-life batteries (and cell phones) at locations statewide, and you have the opportunity to do the right thing with your hazardous waste.
AB 2901 (Pavley, 2004) Cell Phone Takeback and Recycling The Cell Phone Recycling Act requires some of California's largest cell phone retailers to embrace the take-back/recycling model and collect used cell phones, at no cost to the consumer, to be reused, recycled or properly disposed.
AB 1125 (Pavley, 2005) Rechargeable Battery Takeback and Recycling The Rechargeable Battery Takeback and Recycling Act was modeled after the same take-back concept of the cell phone bill. AB 1125 requires all retailers that sell rechargeable batteries to accept back used rechargeable batteries at no cost to the consumer.
Hazardous waste disposal options for businesses
Very Small Quantity Generator Program (VSQG)
The county has a small quantity generator program to assist businesses that generate small quantities of universal waste.
A VSQG (per state law) is any business that generates less than 100 kilograms (about 220 pounds or 27 gallons) of hazardous waste per month. The VSQG Program is designed to provide an inexpensive hazardous waste disposal option to eligible businesses, non-profits, and government agencies.
Visit the VSQG webpage for details.
If you do not qualify for the VSQG program:
If your business generates more than 100 kilograms of hazardous waste per month, you will need to find the appropriate commercial hazardous waste management company (information provided by the San Mateo County Environmental Health Department) to handle your material. Companies that provide this service may be found in the yellow pages or by contacting the County's hazardous waste department at 650–363–4718.
Universal Waste Regulations
Universal wastes are hazardous wastes that are generated by several sectors of society, rather than a single industry. Beginning February 8, 2006 households and small businesses were no longer allowed to put universal wastes in the trash.Universal waste includes:
- all household batteries
- fluorescent and other mercury containing lamps*
- electronic items with a circuit board (for practical purposes, all electronics)
- non-empty aerosol cans
- mercury thermostats
The San Mateo County Household Hazardous Waste (HHW) program collects these wastes from households and small businesses. More information about these wastes and the new regulations is available from The State of California Department of Toxic Substance Control (DTSC).
