Composting at Ole Miss

RKJ_2447-ATThe pilot composting program at Ole Miss began in the fall of 2013 after receiving funding from the Green Fund. The project was awarded $3,000 to collect pre-consumer food waste from the Marketplace at the Residential Colleges. In fall 2014 the compost program expanded to collect food waste from other campus dining facilities including the Marketplace, Rebel Market, Freshii, and Ole Miss Catering. During the Fall semester of 2015, the UM Composting Team composted more than 11,000 pounds of food waste. The program has again received funding to expand in fall 2016.

What is composting?

Composting is the process by which organic materials are broken down by microorganisms at relatively high, yet stable temperatures. This process results in the generation of nutrient-rich soil called humus.

Why does Ole Miss compost?

In a landfill, layers of trash block the flow of oxygen to decomposing food scraps. This results in the release of methane, a potent gas that traps heat in the atmosphere. Food in a compost pile breaks down naturally, greatly reducing the impact of your breakfast, lunch and dinner.

How does the UM Composting Program work?

The program employs a team of four Green Student Interns to collect food material, including fruits, vegetables, grains, eggs, coffee grounds and more, and combines it with dry, nitrogenous materials such as wood chips and leaves. These materials decompose for the duration of the semester on a plot of land at the Maynard W. Quimby Medicinal Plant Garden on campus. The decomposed material creates a rich soil amendment, which is then used at various gardens both on and off campus. If you are interested in using compost from the project in your garden, e-mail green@olemiss.edu.

Purchase Compost

If you’re interested in buying compost, it is now for sale.  Finished compost is currently being used in the UM Garden.  Compost can be bought for $6 per cubic foot or $40 per cubic yard.  E-mail green@olemiss.edu for any questions and orders.

Success

The 2013-2014 academic year saw an overwhelmingly successful implementation of the UM Green Fund’s pilot composting project. During both the fall and spring semesters, pre-consumer food waste from the Residential College’s kitchen was taken to the Medicinal Plant Garden to be composted. In total, the project diverted almost 3,511 lbs. of food waste from the landfill resulting in the creation of 19 cubic yards of compost. The project’s net positive impact on the atmosphere is equally noteworthy. An overall analysis of the Greenhouse Gas (GHG) emissions from the composting project (as opposed to the food waste decomposing in a landfill) found that the project reduced GHG emissions by 1.25 equivalent kg of CO2 per pound of food waste composted. The net total of GHG emissions reduced was over 8 tons! Special thanks to Dr. Cristiane Surbeck’s Civil Engineering 471 class for conducting the environmental analysis for the composting project.

Volunteer Opportunities

The UM composting program provides opportunities to get involved in the composting process. At least once a semester, students, faculty, and staff have the ability to help the Compost Team sift finished compost. Volunteers get to experience the composting process hands on as they work the materials in the matured compost pile through a wire screen that separates things like sticks, rocks, and unfinished compost from the final, nitrogen enriched soil. Sifting the compost is required for the compost to be distributed and important for ensuring a quality soil product because it guarantees that large particles, like sticks and rocks, will not affect the germination and growth of plant seeds

The Fall 2016 Siftsgiving event had a record number of volunteers who sifted an incredible amount of compost. The compost team thanks everyone who helped make Siftsgiving 2016 a success!

Wilson Fund

The compost program is partly made possible through generous donations from people like you. You can donate to the compost program through the Wilson Fund. To donate, visit www.umfoundation.com/umcompost. Donations of any amount are received with gratitude!
