Apr 29, 2023 · Most often, “waste materials” like human excreta, animal waste like livestock manure, sewage sludge, and crop residues are most frequently used as a raw material for biogas production. According to Polprasert ( 2007 ), biogas composition is determined by the type of organic raw materials used and the time and temperature of anaerobic
Apr 1, 2023 · Many studies have proven that a series of substrates with high C/N ratio are suitable for co-digestion with food waste in dry AD systems, including pig manure [51], yard waste [152], green waste [153], cardboard [151], and sewage sludge [149, 154].

Mar 24, 2022 · This paper reviews the pertinent literature from 1970 to 2020 and presents a bibliometric analysis of research trends in the application of solid-state fermentation in the bioprocessing of agro-industrial wastes.
Apr 1, 2024 · In recent years, ex situ fermentation system (EFS) has become increasingly popular for managing livestock waste. It can function dynamically through successive supplementation of collected animal manure and farm wastewater, and completes the resource transformation and harmlessness of waste (mitigating the need for raw manure transportation
Jan 23, 2024 · The C present in livestock manures is part of the renewable carbon cycle, meaning that CO 2 produced from burning waste biogas does not contribute to additional GHG emissions, unlike traditional waste management where C from waste is converted to CO 2 . As a result, the use of biogas derived from livestock manures should be viewed as
Apr 24, 2020 · Furthermore, anaerobic digestion of livestock waste has the potential to play a vital role in farming systems by adding value to agricultural waste and livestock excreta, and reducing their
As a comparison, livestock manure contributed to about 10% of all methane emission in 2015 in the U.S., but only 3% of livestock waste is exploited for biogas production. Using livestock manure in digesters to produce biogas could not only reduce up to 99% of manure pathogens but generate over 13 million megawatt-hours of energy each year.
Nov 1, 2020 · Fermentation process is used for the commercial production of bioethanol from sugar crops and starch crops (Hossain and Jalil, 2015a, Hossain and Jalil, 2015b). In this process, biomass is degraded into starch and the starch is turned into sugar via enzymatic hydrolysis.
Systems for you to make commercial organic fertilizer from composted animal manure. After composting, animal waste becomes nutrient-rich compost. After several days’ stabilization, you can apply it to plants and soil. In addition to personal use, you also can make commercial fertilizer from composted manure. There are two to make
Aug 15, 2023 · The rise in population, urbanization, and industrial developments have led to a substantial increase in waste generation and energy demand, posing significant challenges for waste management as well as energy conservation and production. Bioenergy conversions have been merged as advanced, sustainable, and integrated solutions for these issues, encompassing energy generation and waste upcycling
May 28, 2024 · Based on the data of Table 3, the financial net present value (NPV) of dark and photo-fermentation system is 584,400 CNY (79,843$/kg), the investment payback periods are estimated to be 6.86 years
Jul 27, 2023 · Conversion of livestock manure into organic fertilizer is a sustainable strategy in crop production. In contrast to composted manure, the agronomic characteristics of an anaerobic digestion by-product, digestate, have not been well characterized. This study aimed to investigate the effects of digestate and compost, derived from a pilot-scale livestock waste recycling system, on bioactive
