Community Composting Demonstration Site at Martial Cottle Park

Opportunities to Get Involved

Volunteer with us as we divert organic waste from entering the landfill and turn it into an enriching soil amendment! Check out the different composting systems we are testing at the site, including our continuous flow through (CFT) vermicompost system, aerated static pile (ASP) and classic three-bin system. 

You can get involved at our composting site by volunteering with us every Wednesday morning or third Saturday of the month or by joining our community composting program. More information on our community composting program can be found here.
