When contaminants such as plastic, glass, and other items end up in the green bin, the result is contaminated compost that has fragments of glass, plastic, and other substances that are harmful to the environment.

Compost Workshop

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!

COMPOST WORKSHOP

Date: June 27, 2026
