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.
