Can I Recycle This?

There are a variety of opportunities to recycle and donate items on and off campus. Princeton is committed to reducing its total waste stream while increasing the percentage of recycling across all categories including "household" items, demolition and construction debris, and food waste. Learn more about the University's progress toward our waste reduction goals.

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 (keep caps/lids on) before placing them in the bins.
