The Central Oklahoma Sustainability Collaborative is happy to announce that will be offering a food waste drop off location for the 2022-2023 academic year as part of our recent food waste project grant.* Drop off your food waste in a paper bag or BPI-certified compostable bag (e.g., BioBags) in the Fertile Ground bin west of the Nigh University Center – at the docks outside NUC 151. It will be hauled off weekly and composted!

Why Compost?

An estimated 40% of food grown, processed, and transported in the U.S. will never be consumed. In fact, food reaches landfills and incinerators more than any other single material in the municipal solid waste stream. When that food is sent to landfills, it rots under anaerobic (no oxygen) conditions, giving off methane. Methane is a potent greenhouse gas with 21 times the global warming potential of carbon dioxide. [source]

By composting food waste, this material is broken down in an aerobic (oxygen-rich) process by microorganisms, resulting in no methane release and a nutrient-rich final product that can be used to enhance soil quality (nutrients and structure), filter water runoff, control for erosion, and retain more water for plant growth.

What Can be Donated?

These materials will be composted in a commercial facility, so we can accept more than a backyard composting operation.
