Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste.Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor. The
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
2022/9/1/ · This study examined the effects of biochar, biogas residue, and their combined amendments on CO 2 and CH 4 emission, enzyme activity, and related functional genes during rice straw composting. Results showed that the biogas residue increased CO 2 and CH 4 emissions by 13.07 % and 74.65 %, while biochar had more obvious
2022/12/1/ · The absolute and relative abundances of various C, N, P and S functional genes during composting were shown in Fig. 1.Among the six categories of functional genes for C fixation, organic matter degradation, methane oxidation and N, P and S cycles, those involved in organic matter degradation and N cycling were more prevalent (Fig. 1
2012/11/1/ · The biogas residues (BR-A, BR-B, BR-C and BR-D) were collected from four large-scale municipal biogas plants. Approximately 10 L digested slurry were collected from each biogas plant, portioned into small bottles and stored at −20 °C until use.The composition of the main feedstock to each of the four biogas plant reactors was:
Abstract. 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
2022/12/1/ · The resource usage of biogas residue may be realized by composting and biochar generation of biogas residue, however there are certain issues. For (Omega Bio-tek, Norcross, GA, USA) was used to extract DNA according to the manufacturer's instructions. Primer 338 F/806 R was used to amplify the V3-V4 region of the bacterial 16
2022/12/1/ · Although biogas residue (BR) produced by methane fermentation is rich in nutrients, its unstable components such as reducing Fe 2+ or S 2-may cause phytotoxicity and environmental pollution [3]. Aerobic composting is a suitable method to realize the stabilization and harmlessness of BR.
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
2021/6/24/ · plants were grown in the mixture of compost (75, 50, 25% by volume) and additives (Hygromull, Cocofiber and. SPS-standard soil typ e 73 with 70% peat and 30% clay). Since plants may suffer from
Where is the manufacturer of biogas residue organic fertilizer dryer Manufacturers, Factory, Suppliers From China, The composting machine uses the function of microbial reproduction and metabolism to consume organic matter. During the composting process, the water gradually evaporates, and the physical and chemical properties of the material
2018/6/15/ · The results suggest that biogas residues and SMS compost is a good alternative to peat, allowing 100% replacement, and that 20–50% replacement produces tomato and pepper seedlings with higher morphological growth and
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
2021/4/20/ · Modified biochars prepared from straw, pig manure, and chicken manure biogas residues were used to adsorb and remove ammonium nitrogen (NH4+-N) and chemical oxygen demand (COD) in wastewater. The results showed that at 400–600°C, the adsorption performance of the biogas residue biochars increased with pyrolysis
The biogas fermentation broth can be used directly on the land or dehydrated to restore the land in the form of liquid fertilizer and compost. Recently, in the recycling of organic waste, it is recommended to carry out biogas fermentation first, and then compost the residue to improve the efficiency of compounding and recycling organic waste.
