F&M Compost Co-Op Diverts Costs and CO2 in Lancaster

A Franklin & Marshall College compost initiative has evolved into a co-op saving the City of Lancaster $5,215 per year — all while diverting 16,638 pounds of food waste from the solid-waste stream each month.

The Lancaster Composting Co-Ops (LCC) are a volunteer-led, community initiative enabling Lancaster residents to reduce household food waste by creating high-quality compost. Associate Professor of Environmental Studies Eve Bratman piloted the program.

"F&M students have been involved since the outset in helping to inspire and push along the work," she said.

The idea sprouted in Bratman's senior seminar for environmental studies in spring 2018. She proposed a pilot initiative and received funding from F&M's Center for Sustained Engagement with Lancaster to develop the initial model.

Residents began composting in April 2021, with three bin locations in the city of Lancaster (Musser Park, Lancaster Recycling Drop-Off Center, and Culliton Park). Bins have since been added at Linear Park and Buchanan Park, adjacent to F&M.

The program has grown to 250 households. Membership in LCC is free and open to the public; members are required to attend a brief orientation session and participate in occasional compost maintenance workdays.

Prior to this, Lancaster residents had no alternatives beyond their own backyards to divert organic food and garden scraps from the general waste stream.

Three students spent their summer evaluating and co-authoring a white paper documenting the LCC's first year in terms of cost savings and social impact: Senior Bennett Wasch, junior Caroline Kleis, and sophomore Athena Kotsopriftis.

"Having that quantitative and qualitative data has been really important for informing our efforts and for making the case," Bratman said.


Over 80% of Lancaster Compost Co-op members are Lancaster City residents. In total, 368 individuals' worth of food waste is delivered to LCC compost bins throughout the year.

On average, each individual household average drops off 35.33 lbs of food waste per month. This diverts approximately 16,638 pounds of food waste from the solid-waste stream each month. Annualized, that's nearly 200,000 pounds of food waste composted into beneficial soil (For context, that's roughly the same weight as 33 pickup trucks).

The program also alleviates roughly 39 tons of carbon dioxide equivalent monthly and 472 tons of that equivalent annually — equal to driving almost 100,000 miles every month.

Beyond the cost and carbon savings, the co-ops have expanded into microcommunities that share activities such as neighborhood work days and book clubs.

"Our report doesn't fully capture it, but what we're seeing is that it's not just about composting; it's about building community in all these other ways that are fostering social connections," Bratman said.
