Abstract
Increasing population creates demand for biotechnological products, especially biofuels and bio-based chemicals, due to the difficulties in meeting them with natural resources, recently. By taking into the considerations of the dominancy of nonrenewable resources in industry, circular bioeconomy concept must be applied using biomass and organic wastes having high potential about biorefinery as sustainable resources. When considering biorefinery technologies, techno-economical, environmental, and social assessments must be given particular importance for providing the sustainability and the integration of biorefinery to commercial applications. In the design of new technologies and production systems for biofuels and bio-based chemicals, some approaches are supported by biotechnology improvements. For example, integration of the metabolic engineering and novel technologies for bioconversions with integrated or cascade approaches and optimization of bioprocesses for decreasing the cost of raw materials will pave the way for practicality of wide ranges of these products. Thus fuels and chemicals produced from several resources by biorefinery approaches could compete with the traditional ones, financially and ecologically. In this chapter, while it was given information about evaluation of several biomass and wastes into multiple value-added and sustainable products in biorefinery perspectives, also specific assessments with novel technologies were emphasized. © 2022 Elsevier Inc.
