2022/10/8/ · In this study, biogas residue fermented by biogas engineering was used as compost raw material, and different quality biochar was added in the composting process to explore the effect of biochar on the transformation of heavy metals in the composting process. The composting process was comprehensively analyzed with the
2018/8/1/ · Dissolved organic matter (DOM) extracted from composting of biogas residue was characterized using spectroscopic techniques. Spectral parameters, specific UV absorbance at 254 (SUVA 254), ratios of spectral slopes (S R), and humification index (HIX) were used to assess the structural characteristics of the DOM.During composting,
2022/2/1/ · This experiment was carried out to explore the effects of biochar, biogas residue and their combination amendment on enzyme activities and their stoichiometry during agricultural waste composting. A comprehensive analysis of the variation in, and stoichiometric correlations between, β-glucosidase (BG), N-acetylglucosaminidase
The nirK gene was abundant through composting process. Biogas residues increased the abundance of denitrification genes, resulting in further release of N 2 O. Biochar enhanced nosZ gene abundance and accelerated the reduction of N 2 O. Nitrate reductase (NR), nitrite reductase (NiR), N 2 O reductase (N 2 OR), and ammonia monooxygenase (AMO
2020/1/3/ · Rice straw biogas residue contains high lignin content, so the decomposition of this material by natural compost is slow. This study investigated the effect of the combination of rice straw addition and microbial inoculation (Aspergillus niger CICIMF0410 and Phanerochaete chrysosporium AF96007) on the physiochemical
The maturity of food waste biogas residue during composting was investigated by multivariate interaction of environmental, maturity, and nutrient parameters, using structural equation modeling (SEM). Results showed that the temperature of T2 compost with the microbial consortium increased more rapidly. The pH ranges of T1 (without the microbial
2022/9/1/ · This study examined the effects of biochar, biogas residue, and their combined amendments on CO2 and CH4 emission, enzyme activity, and related functional genes during rice straw composting.
2021/6/15/ · Composting was carried out firstly in a forced aeration composting system (100 L), in which perlite and sawdust were used as additives in different proportions separately or together. Microbial degradation in the co-composting of pig manure and biogas residue using a recyclable cement-based synthetic amendment. Waste
2021/4/1/ · Biochar preparation is a promising strategy for the application of biogas residue. Modification of biochar to enhance its adsorption performance is worthy of consideration. In this work, the biogas residue was hydrothermally pretreated first, and then directly pyrolyzed to biochar (HBRBC). Pristine biochar and hydrochar were also
2022/10/1/ · Effect of diverse Lactobacillus amylophilus, Geobacillus thermoleovorans, and Bacillus subtilis inoculation patterns on the co-composting performance of food waste and biogas residue was explored. Experimental results revealed that, compared to the single-stage inoculation and non-inoculation groups, the multistage inoculation pattern
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

HomeBiogas has developed a revolutionary system that turns organic scraps into clean cooking gas and rich bio-fertilizer, allowing every household to be more sustainable, so you can be confident you’re doing your part for the planet. Shop.
2024/5/3/ · The impact of adding biogas waste (BW) to green waste (GW) composting to increase nitrogen supplementation and improve mature compost quality was investigated. Conducted over 90 days using static windrows, the experiment compared treatments with GW alone (T1) and GW supplemented with BW (T2 and T3). The results
2022/12/1/ · Besides, the introduction of biogas residues may regulate the changes of C, N, P and S elements in the compost system, and biochar and biogas residues can reduce greenhouse gas emissions (Lin et al., 2022, Biochar and biogas residue was used as composting amendments. Biochar was prepared by pyrolysis of rice straw, and
