Loop bioenergy production and carbon sequestration of polymeric waste by integrating biochemical and thermochemical conversion processes: A conceptual framework and recent advances

摘要: Abstract Large volumes of polymeric waste, including natural biomass residues and synthetic motivate the development a general, robust flexible process for mining energy resources contained in these wastes. By analyzing positive negative aspects current, conventional technologies recovery from an integrated concept hybrid technology combining biochemical (anaerobic digestion, gas fermentation, carbon chain elongation) thermochemical conversion processes (pyrolysis, gasification, hydrothermal carbonization) was proposed. The aims at simultaneously enhancing efficiency stability conversion, controlling gaseous aqueous pollution sequestering carbon. This paper presents detailed review state-of-the-art research relating to principles, technical feasibility practices involved each link between two processes.
