Composting on Columbia's campuses is becoming more widespread as partnerships with the Department of Sanitation (DSNY) and private carting companies make pickups easier and more frequent. Learn more about rules for composting and where you can find compost locations on and around campus.


Morningside Campus

What are the rules?

Foods that can be composted:

Fruit and vegetable scraps, non-greasy food scraps (rice, pasta, bread, cereal etc.), coffee grounds & filters, tea bags, egg and nut shells, pits, cut or dried flowers, houseplants and potting soil.

Where can I compost my food scraps?

The Broadway Greenmarket has a food scrap and textile collection site every Thursday and Sunday.

Who collects the food scraps?

GrowNYC collects food scraps at the Greenmarket on Broadway on Thursdays and Sundays. Additionally, the Columbia EcoReps collect food scraps from the dining halls to feed "The Rocket," a composter located in the basement of Ruggles Hall.

What happens to my food scraps?

Food scraps will be transported to one of several NYC compost sites to be transformed into a fertile soil amendment for use on local urban farming and gardening projects.
