The campus bio digester, called Sustainable Composting Research at Princeton (S.C.R.A.P.) Lab, encourages resource reuse by recycling nutrients back into the environment through the conversion of food waste into a soil amendment for campus greens. The goal of the original pilot project was to investigate the potential for decentralized food waste recovery and conversion for campuses, municipalities, and industry. The bio digester is now used regularly to compost on campus. 

Nutrient-rich compost produced by the campus biodigester provides a valuable soil amendment for campus greens. Enriching soil with compost supports healthy vegetation through the suppression of weeds and diseases, which can reduce reliance on synthetic lawn chemicals, thus improving the ecological health of the local environment.
