To combat the issue of food waste, U of I Housing collaborated with F&S Utilities & Energy Services, Operations, Maintenance & Alterations, and environmental compliance. The committee researched various food waste options, including composting, pulpers, and grinder systems used for anaerobic digestion -- including Grind2Energy systems.
These operate similarly to an industrial garbage disposal. However, it uses significantly less water than the digester system, up to 90-95 percent less. Additionally, it does not send the waste directly to the sanitary sewer. The food waste is pumped into a 5000-6000 gallon tank located on the outside of the building it serves. A tanker truck empties the waste and takes it to the local sanitary district. The industrial-strength waste is processed in an anaerobic digester, where it undergoes treatment without oxygen. The methane produced is collected and used to generate electricity at the treatment plant.
