Greenlimbs’ Fifth Annual Treecycle Program  

Jan. 9 marks the fifth year that local environmental group Greenlimbs will host its Treecycle program. Inspired by the work of Northern Liberties Neighbors Association and Passyunk Square Civic Association, Greenlimbs’ Treecycle is a sustainable holiday tree disposal program that diverts holiday greens from landfills by installing collection sites in Pennsport, Queen Village, Society Hill, Washington Square West and Bella Vista. The trees and greens will be chipped and donated to city parks and vacant lots for beautification projects.

The Treecycle project is supported by Bartlett Tree Experts and Whole Foods Market. Since the program began in 2011, Greenlimbs estimates that it has recycled over 1,500 trees, providing mulch to schoolyards and senior centers and deterring weed growth in vacant lots. Visit for a full list of Treecycling sites and volunteer opportunities.

Philadelphia Prison System Recognized by EPA for Food Recovery Project

On Nov. 24, the Environmental Protection Agency recognized the Philadelphia Prison System with an honorable mention for innovation for its food recovery project. The Riverside Correctional Facility and House of Correction facilities produce an estimated 1.35 tons of wasted food per day. Their food waste is now being diverted from its usual course to the landfill and is instead sent to a composting facility or used to nourish the plant and vegetable gardens on prison grounds. 

After the compost is finished, it is donated to local communities and used in the Philadelphia Prisons Orchard Project, which produces fruit for donation and use within the prison system.

The new composting procedure was conceived by Laura Cassidy, executive assistant to the commissioner and Green Program coordinator/project manager in 2013. It is estimated to save the city $31,000 per year in landfill fees. It also works to provide inmates with hands-on job training in horticulture and urban gardening.
