Özet

Agricultural wastes are one of the most abundant lignocellulosic wastes on Earth. Inevitably, this number will increase due to the increasing population needed to be fed. Unfortunately, this substantial amount of resource is underutilized and ends up in different routes: a) incineration b) left in the field to decay, and c) landfill. In all these possible scenarios, it is obvious that they are both non-ecofriendly or unsustainable for society and related industries. Agricultural wastes are noteworthy “inputs” for the circular economy since they possess high nutritional composition. The circular economy is defined as a system in which the “output” of an industry is reused as a “resource” for another industry.  Agricultural and agro-industrial wastes can be converted into value-added products such as enzymes, biofuels, pharmaceuticals, food/feed enhancers, green chemicals, bioplastics, etc. In this way, we can eliminate the problems related to waste management and lower our environmental impact. In addition, a circular bioeconomy can lower the production cost of bioprocesses, create regional job opportunities, and support farmers. This review discusses industrially important products produced via bioprocessing agricultural feedstocks and related examples from the literature are given.
