Biohythane, Biogas, and Biohydrogen Production from Food Waste: Recent Advancements, Technical Bottlenecks, and Prospects

Energies, Journal Year: 2024, Volume and Issue: 17(3), P. 666 - 666

Published: Jan. 30, 2024

Food waste (FW) is a significant global issue with carbon footprint of 3.3 billion tonnes (Bt), primarily generated due to improper food supply chain management, storage issues, and transportation problems. Acidogenic processes like dark fermentation, anaerobic digestion, combination DF-AD can produce renewable biofuels (Bio-CH4, Bio-H2) by valorising FW, aligning the UN SDGs. FW an ideal substrate for acidogenic its high moisture content, organic matter, biodegradability. However, choice valorisation pathways depends on energy yield, conversion efficiency, cost effectiveness. are not economically viable industrial scale treatment reduced recovery from stand-alone processes. So, this study reviews comparative studies biogas, biohydrogen, biohythane production via processes, focusing recovery, environmental economic impact provide clear understanding yield all Additionally, review also explores recent advancements in digestate slurry management synergistic effects AD HTC Lastly, futuristic integrated bio-thermo-chemical process proposed maximum valuing vectors (Bio-H2, Bio-CH4, hydro-char) along biofertilizer production.

Valorization of Algal Biomass to Produce Microbial Polyhydroxyalkanoates: Recent Updates, Challenges, and Perspectives

Polymers, Journal Year: 2024, Volume and Issue: 16(15), P. 2227 - 2227

Published: Aug. 5, 2024

Biopolymers are highly desirable alternatives to petrochemical-based plastics owing their biodegradable nature. The production of bioplastics, such as polyhydroxyalkanoates (PHAs), has been widely reported using various bacterial cultures with substrates ranging from pure biowaste-derived sugars. However, large-scale and economic feasibility major limiting factors. Now, algal biomass for PHA offers a potential solution these challenges significant environmental benefit. Algae, unique ability utilize carbon dioxide greenhouse gas (GHG) wastewater feed growth, can produce value-added products in the process and, thereby, play crucial role promoting sustainability. sugar recovery efficiency is variable depending on pretreatment procedures due inherent compositional variability among cell walls. Additionally, yields, composition, properties synthesized vary significantly microbial producers algal-derived Therefore, microalgal pretreatments synthesis copolymers still require considerable investigation develop an efficient commercial-scale process. This review provides overview discusses strategies enhance its properties, focusing managing GHGs sustainable future.
