Electronic regulation to achieve efficient anaerobic digestion of organic fraction of municipal solid waste (OFMSW): strategies, challenges and potential solutions

Frontiers of Environmental Science & Engineering, Journal Year: 2024, Volume and Issue: 18(4)

Published: Jan. 1, 2024

Abstract Anaerobic digestion (AD) of organic fraction municipal solid waste (OFMSW) is prone to system breakdown under high loading rates (OLRs) condition, which subsequently reduces the efficiency process and results in substantial economic losses. In this perspective paper, substances metabolisms, electrons flow, as well microbial interaction mechanisms within AD are comprehensively discussed, underlying bottleneck that causes inefficient methane production identified, “electrons surplus”. Systems encountering severe electron surplus at risk failure, making it crucial proactively prevent phenomenon through appropriate approaches. On basis, present proposes three potential electronic regulation strategies surplus, namely, shunt, accelerating transfer regulating methanogenic metabolism pathway, presents specific methodologies for each strategy. Furthermore, solutions challenges may occur during also presented paper. This aims provide innovative approaches achieve efficient stable operation OFMSW anaerobic digestion, especially OLRs condition.

A Review on Start-Up Phase Optimization of Kitchen Waste Anaerobic Digestion

Fermentation, Journal Year: 2023, Volume and Issue: 9(7), P. 603 - 603

Published: June 27, 2023

Kitchen waste has been confirmed as an appropriate substrate for anaerobic digestion, although means of alleviating the difficulties and time-consuming nature start-up phase need to be further explored. Based on mechanism we discuss factors influencing kitchen waste. By controlling temperature, pH, organic loading rate, inoculation ratio other parameters, high activity methane-producing archaea bacteria can intensified, thereby increasing biogas yield. Furthermore, introduce methods pretreatment, operating condition optimization conductive material addition. Finally, put forward future perspectives research gaps related accelerating bioreactors utilized biodegradation.
