MODERN CONCEPTS OF BIOPROCESSING: FROM LINEAR ECONOMICS TO CIRCULAR BIOECONOMICS

Abstract

The review examines modern concepts of biorefinery as a key element of the transition from a linear economy to a circular bioeconomy. The main models of biorefinery are analyzed: platform concepts based on biorefinery, cascading use of biomass, and integration into industrial symbiosis systems. Special attention is paid to methodological approaches, including life cycle analysis (LCA) and technical and economic analysis (TEA). As a result of data systematization, key trends have been identified: a shift in focus from biofuel production to the production of high-margin bioproducts, the integration of various technological flows, and the digitalization of processes. In conclusion, the prospects for the development of biorefinery are outlined, including the introduction of artificial intelligence, synthetic biology, and the development of hybrid (chemical and biological) conversion methods.
