Abstract

Food waste (FW) can be utilized as a raw material to produce energy such as hydrogen via fermentation, which is a more attractive and environmentally friendly approach compared to incineration and land-filling. Food waste must be pretreated before being used in various biological processes. The choice of the pretreatment method usually depends on the composition of the food waste. Therefore, various pretreatment methods generally employed to treat FW, including physical, physiochemical, chemical and biological pretreatments, are summarized in this review. The different pretreatment methods are compared in terms of their efficiency and biohydrogen yield. Additionally, the energy efficiencies of the various pretreatment methods are compared, thereby leading to the selection of the most efficient pretreatment method.
