CVSan Holds Ninth Annual Zero Waste Week for the Community

Castro Valley Sanitary District (CVSan) presented its Ninth Annual Zero Waste Week during the week of February 26th – March 2nd, with fun and engaging events in the community. Zero Waste Week is a celebration of zero waste practices like Reduce and Reuse and is a significant event as CVSan continues on its path towards the goal of zero waste by 2029.

Reduce Wasted Food: On Saturday, March 2nd at Castro Valley Little League Opening Day, CVSan provided over 300 reusable silicone snack pouches to event participants. Participants learned about food and packaging waste and were directed to additional resources at

STEAM Kits: CVSan coordinated a Science, Technology, Education, Art, and Math (STEAM) Kit project with supplies that would have otherwise been landfilled. Over 300 students from 13 classrooms in Castro Valley worked with materials such as plastic straws and utensils, polystyrene, and metallic wrapping paper. Selected projects are on display at the Castro Valley Library during March and April.

Bike Repair Event: CVSan and the organization Bay Area BikeMobile repaired 33 bicycles at the CVSan Office on March 2nd! Repairing broken goods helps extend the useful life of the item and, in this case, helps reduce greenhouse gas emissions from cars. Visit to view their calendar and see where they’ll be making repairs next! Ready to move on from your bike? Schedule a Bulky & Reuse Pick-Up by calling Alameda County Industries at (510) 483-1400.

Reusable Napkin Giveaway: CVSan distributed over 100 organic cotton napkins to students at Canyon Middle School and Creekside Middle School during Zero Waste Week. 135 Students and parents completed an online pledge to refuse disposable napkins and committed to carrying their new napkins in their backpacks or lunchboxes.
