Fiberight and Southampton have just completed a BIV project on ‘Recovery of food waste from municipal solid waste (MSW)’ during pulping, with funding from the BBSRC FoodWasteNet NIBB (www.foodwastenet.org). The aims of the work were to test an alternative separation technology for Fiberight’s innovative MSW-based sugar platform process, and determine how much food waste can be recovered from different stages. The sidestreams can then be tested for their potential to produce energy and higher-value products. The process is thus a key part of a waste-based biorefinery.
