The disposal of plastic solid waste (PSW) has become a major worldwide environmental problem. New sustainable processes have emerged, i.e. either advanced mechanical recycling of PSW as virgin or second grade plastic feedstock, or thermal treatments to recycle the waste as virgin monomer, as synthetic fuel gas, or as heat source (incineration with energy recovery). These processes avoid land fi...

This contribution is based on the monograph entitled “Recent Advances in Thermochemical Conversion of Biomass”, covering both general items as well as the primary processes, like fast pyrolysis, gasification, hydrothermal liquefaction, carbonization and secondary processes, like co-processing of bio-oil in fluidized catalytic cracking (FCC), Fischer-Tropsch synthesis and valorization of lignin ...

Bioenergy production is one of the most reliable strategies for replacing fossil fuels and reducing CO2 emissions. Gasification-based bioenergy generation has been extensively studied; however, it still facing challenges limited energy efficiencies, especially upon small-scale development. Concentrated solar thermochemical gasification biomass (CSTGB) where endothermic reactions are driven by c...

With the objective of gaining a better understanding of the system design tradeoffs and economics that pertain to biomass-to-liquids processes, 20 individual BTL plant designs were evaluated based on their technical and economic performance. The investigation was focused on gasification-based processes that enable the conversion of biomass to methanol, dimethyl ether, Fischer-Tropsch liquids or...

The use of gas fermentation for the production of low carbon biofuels such as ethanol or butanol from lignocellulosic biomass is an area currently undergoing intensive research and development, with the first commercial units expected to commence operation in the near future. In this process, biomass is first converted into carbon monoxide (CO) and hydrogen (H2)-rich synthesis gas (syngas) via ...
