The Problem

Almost 25% of Mercer County trash is food and organic waste, which produces abundant methane when left to decompose in the landfill, and, so far, there is no proven or efficient strategy to fix this issue.

The Idea

The municipality of Princeton will use behavioral science to develop interventions to reduce food waste, and install a local food digester to turn the waste into compost for local farms, keeping organics out of landfills and reducing methane gas emissions.

What Mayor Liz Lempert is saying:

I am thrilled at this opportunity for Princeton to develop a decentralized system to recycle food waste back into compost. Our idea has the potential to significantly reduce greenhouse gas emissions and hauling costs while, at the same time, enhancing the health and productivity of our local soils.
