Master Composter Certficate Course

About:

The Master Composter Certificate Course educates and empowers New Yorkers to get involved in community composting via education, outreach, advocacy and more. This advanced education and outreach program is open to New Yorkers who are at least 18 years of age. We are grateful that funding for this program was restored for FY27 from the City Council. Currently funding is through June 30, 2027.

The Master Composter Certificate Course workshops, field trips, and volunteer opportunities are led by many community composting organizations around the five boroughs of NYC and you can participate in activities at a variety of locations.

The LES Ecology Center administers the program in close coordination with the other organizations. Current workshop instructors include Snug Harbor, Queens Botanical Garden, Lower East Side Ecology Center, NYBG Bronx Green Up and Big Reuse.

To become a Certified NYC Master Composter, participants need to create an account on Regpack via the Registration page. An important note if you access the site on a phone: the “Register” page will likely only show you the Regpack site; to view the list of other options and full web page, view the “Desktop Site” on your phone. (To do this, when you are on the website, go to the 3 dots in the corner and Select Desktop Site)
