NYC Compost Project hosted by Snug Harbor Cultural Center & Botanical Garden

The NYC Compost Project, created by the NYC Department of Sanitation in 1993, provides compost education and outreach to NYC residents, community groups, city agencies and non-profits.

The NYC Compost Project offers compost-related workshops and classes, runs the Master Composter Certificate Program, provides technical composting support, distributes DSNY compost & mulch, develops urban farms, and tables at public events throughout all five boroughs. The NYC Compost Project also operates neighborhood-based food scrap drop-off opportunities and ensures that those food scraps are composted locally.
