  • Financial Assistance – CVSan provides schools with signs, as well as indoor and outdoor recycling and food scrap recycling containers.  In 2019, CVSan donated over $5,000 in supplies to Castro Valley schools.  Click here to complete a Donation & Supply Request Form or to learn more about donations available.
  • Food Scrap Recycling – Recycling food scraps at school can be challenging, but it is often the single most effective waste reduction action a school can take.  Castro Valley schools that compost food scraps divert an average of 85% of their waste away from landfill!   Click here to learn more about the history of our Food Scrap Recycling program and what schools are doing now.
  • Waste Audits – A waste audit identifies materials going into the garbage that could have been recycled or composted.  Students, teachers, and parent volunteers sort through one day’s worth of garbage.  Waste audits are offered for a limited time (October through February) and are a Green Ribbon requirement.  Visit our Waste Audit page to sign-up.
  • Earth Day Clean-Up and Free Compost & Mulch – Sign up to participate in CVSan’s Earth Day Clean-Up event held in April each year to clean up and beautify your campus.  Registration is available in February and participating schools are eligible to receive free compost and mulch.
