2021/7/14/ · Biogas and biohydrogen are compatible gaseous biofuels that can be blended with natural gas for reticulated fuel supply to reduce greenhouse gas emissions. Sustainably grown woody biomass is emerging as a potential feedstock in the production of biofuels. Woody biomass is widely available, uses non-arable land for plantation, does not
2024/3/14/ · Anaerobic digestion is a potential treatment for industrial wastewater that provides valuable end-products, including renewable energy (biogas). However, waste streams may be too variable, too dilute at high volumes, or missing key components for stable digestion; all factors that increase costs and operational difficulty, making
2022/6/17/ · In this study, biochar derived from biogas residue was prepared, and the degradation efficiency of phenol by permanganate (KMnO 4 ) increased from 25.3% to 73.4% in 60 min in the presence of
2021/10/1/ · The effect of the IBS was more obvious due to its lower ORPs. Finally, the ORP decreased to −150 – −250 mV. Anaerobic condition was more conducive to FW fermentation, and the reactors with biogas slurry addition had more fermentation products. Feng et al. (2020) found that ORP was −18 – –223 mV for lactic acid
The subtitle "Waste-to-Biogas" makes it clear that the range of plants covered has been extended to include residual waste biogas plants. Biogas plants based on renewable raw materials are still not included. The new Biogas Compendium presents a total of 123 plants in Germany and 162 plants in other European countries.
The development of new biogas projects fell sharply after 2011 as the value of emission reduction credits awarded under the CDM dropped. Thailand produces biogas from the waste streams of its cassava starch sector, biofuel industry and pig farms. India aims to develop around 5 000 new compressed biogas plants over the next five years (GMI, 2019).
2019/10/29/ · Under different proportions of raw materials, the cumulative biogas production first increased and then decreased. The best biogas production is at a temperature of 50°C and a proportion of cow dung, deer manure, and mushroom fungus is 0.3:0.4:0.3. The unit total solid biogas production rate reached 0.23 L·g −1. The mixed
2022/5/1/ · Biogas residue (BR) is difficult to transport and compost due to its high moisture content. The purpose of this study was to elucidate the dewatering and microbial mechanisms underlying the
2024/5/16/ · Biogas is a renewable energy source generated through the anaerobic digestion (AD) of organic feedstocks. This study aims to quantify the biogas production potential (BPP) of fruit wastes via semi-continuous lab-scale mesophilic AD over a total of 100 days. The feed was composed of 80% banana peelings and 20% pineapple residues,
2022/6/22/ · Therefore, it is urgent to find appropriate way to improve the efficiency of dry anaerobic fermentation and reduce the great amount of biogas residue. In this study, a tentative experiment was conducted to investigate the effect of biochar prepared from biogas residue on the performance of dry anaerobic fermentation system.
2012/9/1/ · 1. Introduction. Energy crisis and global warming are considered to be two most serious problems worldwide [1].Biomass energy, as a renewable and sustainable form of energy, is becoming more important due to its environmentally-sound and energy-saving production [2].Development of a livestock industry is believed to be a key
2018/1/30/ · The company says that its recently developed BEKON MINI system enables dry fermentation to be conducted even in the smallest spaces and with low input quantities. The new biogas plant in Enger has an annual input capacity of 8 500 tonnes of biowaste consisting of kitchen and garden waste, from which some 1.1 million Nm3 of
2012/5/24/ · Biogas production from winemaking waste – yeast biomass and wine residue containing substrate (wine lees) was investigated. Laboratory scale 700 ml batch anaerobic digesters were used. The
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
2018/8/1/ · The anaerobic fermentation experiments were carried out at a temperature of 35 °C and the entire process lasted 30 days. Biogas slurry was sprayed twice a day for a minimum of 30 min each through a dump pump to increase heat and mass transfer. Biogas residues were collected after 30 days of anaerobic fermentation and then composted.
