Recycling Guidelines

There are a variety of opportunities to recycle and donate 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. 

Recycling on Campus App:

Princeton Facilities recently launched the “Recycling on Campus” mobile app to make recycling easier for the campus community. Through the app's search function, users will be able to quickly determine what can--and can't--be recycled on campus. They will also receive updates about campus recycling and related initiatives.

The app can be accessed free of charge from mobile devices through the iTunes Store and Google Play, or through digital assistants like Amazon Alexa and Google Home. Recycling on Campus is also available online.

Recycling Guidelines:

Everywhere on campus you can mix all acceptable recyclables - paper, plastic, metal, etc. - in any recycling bin, even if the label says otherwise; all bins will soon be accurately labeled. Be sure to read the recycling guidelines below and empty out containers (remove caps/lids) before placing them in the bins. 

Help us make recycling a success on campus by recycling properly and avoiding contamination. Visit our FAQ page on contamination and recycling for more information.

  • 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.
