Food waste composting
All food waste at the South Kensington campus is taken to the Rothenburg Unit located on Aryton Road to the rear of the Sherfield Building. The Rothenburg Unit is a food storage tank that macerates the food into a liquid and then stores it. Once the tank is full the tank is removed by a road tanker. The food waste is taken to anaerobic digestion plant where electricty is generated.
Sending food waste for anaerobic digestion contributes to reducing the amount of waste sent to incineration, and lowers the College’s carbon footprint. Energy is produced from the food waste being sent for anaerobic digestion.
