REUSE – “Again!”, the CVSan Schools Program Theme for 2014/15

We are moving up the 4Rs hierarchy and “Again!” is the theme for the 2014/15 school year. “Again!” is a call to think about Reuse strategies wherever possible on campus. Reuse practices include repairing a broken toy or electronic, using a reusable container for lunch or leftovers, shopping/consigning/donating items for reuse, and hosting waste-free parties. For the Green Ribbon application, “Again!” means you will be rewarded for putting in the extra effort in the Reuse section.  Visit our Reuse page for more resources.

  • Technical Assistance – CVSan and Waste Management staff are available to perform a free site assessment at your school.  A recycling coordinator will evaluate your school’s potential to prevent waste, as well as recycle or compost materials that currently go in the garbage.  Contact CVSan at 510-537-0757 for more information.
  • Financial Assistance – CVSan provides blue and green indoor/outdoor recycling and food scrap recycling containers and signs to Castro Valley schools.  In fact, nearly $6,000 worth of supplies were donated to schools last school year.  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 73% of their waste away from landfill!  Click here for a step-by-step guide to starting a food scrap recycling program at your school.  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 the type of material going into the garbage that could have been recycled or composted.  Students, teachers, and parent volunteers sort through one day’s worth of garbage.  Visit our Waste Audit page to sign-up; waste audits are offered for a limited time (October through February) and are a Green Ribbon requirement.  
  • Earth Day Clean-Up with 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.
