The Master Composter Program is designed to extend composting information to the public through volunteers who have successfully completed a comprehensive training program. This free educational program is made available through the County of San Mateo.
Master Composters agree to give back to the community a minimum of 50 hours of volunteer service in the form of approved educational outreach throughout the County. This can be done in a variety of ways such as giving workshops at schools, community centers, staffing a booth at the County Fair or writing a news release for a paper.
