Popis: Biorefineries contribute to a circular bioeconomy using renewable feedstock to produce commodity and specialty chemicals as an alternative to petroleum chemicals. Using waste streams such as food waste and agricultural waste as a feedstock for biorefineries is a promising approach for obtaining value-added products in an economically feasible and sustainable way. The conversion of biomass to chemicals offers diverse opportunities but poses new technological challenges. This paper aims to review the current state of food and agricultural waste valorisation by giving a brief technical overview, summarizing the current state of the bio-based market, and identifying the current barriers to scaling-up biorefineries. Utilizing lignocellulosic biomass in biorefineries calls for pre-treatment due to its complex structure, in which biomass is broken into monosaccharides, building blocks of value-added products. Different state of the art technologies for lignocellulose pre-treatment is introduced in the review followed by a brief explanation of the role of the hydrolysis and fermentation. The economic aspect of chemical production from biomass waste at an industrial scale is also introduced by giving an overview of some recent techno-economic studies.
