Zero Waste Guide

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 *ON HOLD DUE TO COVID-19*

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.

Reuse and Donation Options on Campus


The University sends its food waste to Organic Diversion, a food waste hauler based in Marlton, N.J. Organic Diversion is unique in the industry because of its collection methodology and technology, which turns a portion of the food waste it collects into renewable energy. Organic Diversion steps in when food cannot be sold or repurposed, and diverts it from landfills to reduce the impact on the environment.

In September 2018, the Office of Sustainability launched a food scraps demonstration project to support both the University’s sustainability goals and research and education mission. The Sustainable Composting Research at Princeton Lab or S.C.R.A.P. Lab involves a FOR Solutions Model 1000 composting system. The S.C.R.A.P. Lab is located behind the FitzRandolph Observatory building and 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.

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.
