Composting comes to Frist

There are a variety of opportunities to reduce, reuse and recycle items on and off campus. One of the key goals in Princeton's Sustainability Action Plan is to strive for zero waste through behavioral and operational strategies that include reduction, reuse and recycling. To learn what's recyclable on campus, visit the Recycling Guidelines page.

Choose to Reuse

One of the strategies to achieve our zero waste goal is to increase reuse of a broader range of items on campus. Here are a few opportunities to reduce your everyday waste by choosing to reuse:

Drink Local

With more than 250 filtered water bottle-filling stations on the Princeton campus, students, staff and visitors have easy access to free filtered water for their reusable water bottles and mugs. "Drink Local" water bottles can be purchased at the U-Store on University Place.

Reusable Mug Discount

Campus Dining provides offer discounts to Princeton campus community members who use their own reusable mugs instead of disposable cups in Cafe Vivian, the Food Gallery at FristChancellor Green Cafe, and Studio '34.

In September 2018, we launched a food scraps demonstration project called the Sustainable Composting Research at Princeton Lab or S.C.R.A.P. Lab. The S.C.R.A.P. Lab converts a portion of the campus’s uneaten food into a nutrient-rich soil amendment for campus grounds, while supporting academic research around organics recycling. The University started collecting food scraps at major dining venues on campus and Lakeside and Lawrence apartments graduate student housing. Composting at Frist Gallery was introduced in 2023, through a strong partnership between staff in Facilities and University Services, as well as the introduction of new compostable containers and utensils. Updates on the SCRAP lab can be found on the project's Blog.

Graduate Students have opportunities to compost at their apartment complexes. Contact your residence council or committee for more information about how and where to compost.

The University also partners with Organic Diversion, a food waste hauler based in Marlton, N.J. to recover uneaten food when it cannot be sold or donated. Organic Diversion diverts the food to either animal feed or composting, thereby promoting environmental health and justice by reducing reliance on landfills and incinerators.
