 This paper discusses the potential of agricultural residues such as lignocellulosic materials, LM, as renewable bioenergy sources, and the effectiveness of anaerobic digestion in biogas production. The study highlights the need for experimental investigation of physiochemical changes during pretreatment to develop mechanistic models for rational design of pretreatment processes. Various cutting-edge pretreatment technologies are being tested, including microerobic pretreatment, MP, which has gained attention due to its potential for LM degradation with limited oxygen supply and mild conditions. MP is environmentally friendly, technically and economically feasible, and uses fewer enzymes and less energy for methane production. The paper provides background knowledge necessary for finding a promising solution to methane production. This article was authored by Farak Raza Amin, Habiba Khalid, Henjom, and others.
