Abstract
Directly, the utilization of petroleum-based fuels for energy supply in numerous applications has led to their depletion accompanied by an increase of global warming to the atmosphere. Hence, the paramount need for exploring new renewable energy sources has become in demand. Believing in the concepts of sustainable development to overcome these issues, the immense waste biomass has been recognized as a promising, clean and viable solution for future energy and fuels. In this regard, this review concisely presents the latest cutting-edge of different integrated refining strategies for the conversion of biomass to valuable liquid fuels (BTL) to reduce the dependency on conventional fuels. Economic insights for the production of biofuels have been distinctively assessed. From the economic point of view, thermochemical conversion methods of biomass to fuel are considered as promising integrated approaches because of their flexibility towards various types of biomasses and their efficiency to produce valuable products such as viable fuels, heat, and electricity. Bibliometric mapping has been thoroughly conducted to identify the latest literature studies within (bioenergy/biofuel) field. Dynamically, future efforts in the biomass management sector are also advised for producing green liquid fuels to meet the global energy demand through large commercial scales.
