Abstract The global energy demand is projected to rise by almost 28% 2040 compared current levels. Biomass a promising source for producing either solid or liquid fuels. Biofuels are alternatives fossil fuels reduce anthropogenic greenhouse gas emissions. Nonetheless, policy decisions biofuels should be based on evidence that produced in sustainable manner. To this end, life cycle assessment (LCA) provides information environmental impacts associated with biofuel production chains. Here, we review advances biomass conversion and their impact assessment. Processes gasification, combustion, pyrolysis, enzymatic hydrolysis routes fermentation. Thermochemical processes classified into low temperature, below 300 °C, high higher than i.e. combustion pyrolysis. Pyrolysis because it operates at relatively lower temperature of up 500 which 800–1300 °C. We focus 1) the drawbacks advantages thermochemical biochemical various possibility integrating these better process efficiency; 2) methodological approaches key findings from 40 LCA studies pathways published 2019 2021; 3) bibliometric trends knowledge gaps using routes. integration hydrothermal circular economy.

In the past decades, considerable attention has been directed toward anaerobic digestion (AD), which is an effective biological process for converting diverse organic wastes into biogas, volatile fatty acids (VFAs), biohydrogen, etc. The microbial bioprocessing takes part during AD of substantial significance, and one crucial approaches deep adequate understanding manipulating it different products microbiology. Due to highly complexity microbiome, critically important study involved microorganisms in AD. recent years, addition traditional methods, novel molecular techniques meta-omics have developed provide accurate details about communities Better microbiomes could guide us identifying controlling various factors both improving diverting metabolic pathway production selective bio-products. This review covers platforms that results final from microbiological point view. also highlights distinctive interactions occurring among communities. Furthermore, assessment these existing digesters discussed more insights their structure, dynamics, pathways. Moreover, affecting each platform are highlighted. Finally, provides some applications bio-products deals with challenges future perspectives

Up-flow anaerobic sludge blanket (UASB) reactor belongs to high-rate systems, able perform reaction at reduced hydraulic retention time, if compared traditional digesters. In this review, the most recent advances in UASB applications are critically summarized and discussed, with outline on critical aspects for further possible future developments. Beside treatment of soluble biodegradable substrates, research is actually focusing refractory slowly degradable matrices, thanks an improved understanding microbial community composition hydrodynamics, together utilization powerful modeling tools. Innovative approaches include use nitrogen removal, as well hydrogen volatile fatty acid production. Co-digestion complementary substrates available same territory being extensively studied increase biogas yield provide smooth continuous operations a circular economy perspective. Particular importance given decentralized treatment, electricity heat local users integration other renewable energies. Proper pre-treatment application increases yield, while successive post-treatment needed meet required effluent standards, also from toxicological An increased full-scale technology desirable achieve sustainability scopes, efficient exploitation, fulfilling energy targets green-house gases emission reduction, particular tropical countries, where limited heating required.

Abstract The global amount of solid waste has dramatically increased as a result rapid population growth, accelerated urbanization, agricultural demand, and industrial development. world's is expected to reach 8.5 billion by 2030, while production will 2.59 tons. This deteriorate the already strained environment climate situation. Consequently, there an urgent need for methods recycle waste. Here, we review recent technologies treat waste, assess economic feasibility transforming into energy. We focus on municipal, agricultural, found that methane captured from landfilled-municipal in Delhi could supply 8–18 million houses with electricity generate 7140 gigawatt-hour, prospected potential 31,346 77,748 gigawatt-hour 2030 2060, respectively. Valorization food anaerobic digestion systems replace 61.46% natural gas 38.54% coal use United Kingdom, reduce land 1.8 hectares if provided animal feeds. also estimated levelized cost landfill waste-to-energy $0.04/kilowatt-hour $0.07/kilowatt-hour, payback time 0.73–1.86 years 1.17–2.37 years, Nonetheless, current treatment are still inefficient, particular treating containing over 60% water.
