Life Cycle Analysis of the bioethanol production from food waste: A review

Food Waste because of its composition is considered as a promising feedstock for the production of biofuels and in particular bioethanol. From a technical point of view, the production of bioethanol from lignocellulosic materials is a well-studied process consisting of the stages of pretreatment, enzymatic hydrolysis, fermentation and product recovery. However, the legal framework regarding biofuels has established specific environmental criteria for their production which are regularly updated. The most common tool for the assessment of the environmental performance of a process or product is the Life Cycle Analysis. In the present review, the results of LCA studies on the production of bioethanol from food waste are presented. Significant differences are observed among the studies in terms of the methodological choices made. Despite the high heterogeneity observed which does not allow a direct comparison among them, there is strong evidence that the production of bioethanol from food waste is an eco-friendly process which can substantially contribute to Green House Gas emissions savings.
