About Scraps to Soil

The Town of Greenwich, in partnership with Waste Free Greenwich, Greenwich Recycling Advisory Board and Greenwich Green & Clean, launched a municipal food scrap recycling program for the Town of Greenwich in June 2020. To date, residents have voluntarily dropped off over 780,000 lbs of food scraps at collection sites located at Holly Hill, Old Greenwich and Round Hill, diverting this valuable material from incineration to beneficial, nutrient-rich compost!

In spring 2026, "smart" bins for food scrap recycling will be launched at Binney Park and Cos Cob Park. These app-accessed, secure smart bins will be available 24/7, making participation in the program even easier and increasing the tonnages diverted. Registered residents utilize an app to unlock the enclosed, secure collection bins, which are designed to reduce contamination and enhance cleanliness. Detailed instructions for the Scraps to Soil Food Scrap Recycling Program are available below.

Funding for the smart bins was provided by the Materials Management Infrastructure (MMI) Grant program administered by the Connecticut Department of Energy and Environmental Protection (DEEP). Competition for the grant was strong, with 20 applications submitted requesting approximately $30 million in funding, and Greenwich was one of only nine applicants to receive an award. Similar programs have been launched in Manchester, West Hartford, Ridgefield, Kent and Wilton, among other neighboring towns. New York City and Washington, D.C. also have thriving, well established programs utilizing these smart bins for food scraps.

Please complete this short survey. Your valuable feedback will help the program run smoothly and efficiently and shape future initiatives to further reduce municipal waste.
