2023/12/1/ · 1. Introduction. With the promotion of “Zero-Waste City” in China, the centralized anaerobic digestion of kitchen wastes produces a large amount of biogas residue (Jin et al., 2021), and its treatment, disposal and resource utilization have become the main problems currently faced.Composting (or humification) is considered to be an
The effects of different proportions of cattle manure (CM) and biogas residue (BR) on the degradation of lignocellulose and humification during composting were investigated. The results showed that increasing the CM content prolonged the thermophilic period duration, thus promoting organic matter degradation and enhancing the humification

2023/10/19/ · The utilization of biogas and biogas residues is an important objective of animal manure resource management. Regarding the environmental friendliness and economic suitability of utilization modes, previous studies have evaluated and compared biogas or biogas residue individually, which may lead to incomplete environmental and
2023/12/1/ · Nitrous oxide (N 2 O) production is associated with ammonia-oxidizing bacteria (amoA-AOB) and denitrifying fungi (nirK-fungi) during the incorporation of biochar and biogas residue composting.This research examined the relative contribution of alterations in the abundance, diversity and structure of amoA-AOB and nirK-fungi
2019/11/30/ · DOI: 10.1016/j.biortech.2019.122518 Corpus ID: 208955119; Odor emission and microbial community succession during biogas residue composting covered with a molecular membrane. @article{Li2019OdorEA, title={Odor emission and microbial community succession during biogas residue composting covered with a molecular
2024/4/3/ · The impact of biogas residual biochar (BRB) on the humification and carbon balance process of co-composting of hog slurry (HGS) and wheat straw (WTS) was examined. The 50-day humification process was significantly enhanced by the addition of BRB, particular of 5% BRB, as indicated by the relatively higher humic acid content
2022/11/8/ · Composting is an excellent way to recycle biogas residues into a stable, non-toxic agricultural end product. In this study, the dynamic changes of physical–chemical parameters and bacterial community in three groups of bioaugmentation composting systems at different moisture contents (MC) of 50% (MC50), 60% (MC60) and 70%
