Countywide Integrated Waste Management Plan

The California Integrated Waste Management Act directs counties to prepare a Countywide Integrated Waste Management Plan (CIWMP). This plan consists of a Source Reduction and Recycling Element (SRRE), a Household Hazardous Waste Elements (HHWE), and a Nondisposal Facility Element (NDFE) of each jurisdiction, the Countywide Siting Element, and the Countywide Integrated Waste Management Summary Plan. The CIWMP addresses waste management conditions and provides an overview of the actions that will be taken to achieve the diversion requirements of Public Resources Code section 41780 and to maintain 15 years of disposal capacity.

California statute requires the County of San Mateo to review its CIWMP every five years and then report on its adequacy to the California Integrated Waste Management Board (CIWMB). The last review of the CIWMP was completed in 2024.

Depending on the results of the review, a revision to the CIWMP may be required; however, minor updates to its elements may also be completed annually through the Electronic Annual Report.

Learn how easy and fun it is to recycle your fruit and vegetable scraps, leaves, and plant cuttings into compost in these free workshops! These workshops teach composting options suitable for those with or without a backyard. Apartment dwellers welcome! Compost provides valuable nutrients for your garden soil, helps retain moisture, which saves water, prevents erosion, loosens clay and compacted soils for better drainage, and suppresses weeds. It is rewarding to know you are turning what some consider waste into precious organic material for your garden.

Discounts and rebates for backyard compost and worm compost bins will be distributed to San Mateo County residents!
