Jan 29, 2024 · The main source of GHG emissions from ruminant livestock production systems is the methane created during enteric fermentation and manure processing and storage. However, there is no single, better method for quantifying methane in animal or dung waste . Some approaches are more suited for small-scale situations, mostly because they were
Apr 29, 2023 · Animal waste treatment system is a Diversity and dynamics of the bacterial community involved in pig manure biodegradation in a microbial fermentation bed system ...
Livestock Water Recycling is the world’s leading provider of manure treatment technology. From our Innovation Center in Calgary, Alberta, we work with farms around the world to help reduce greenhouse gas emissions, concentrate and segregate nutrients for strategic fertilizer application, and recycle clean, reusable water.

Oct 22, 2024 · The results of the screening experiment reveal the potential of marine-derived fungi to ferment and hydrolyze livestock waste containing polysaccharides and cellulosic materials. The process involved autoclaving the livestock waste followed by inoculation with each isolated fungus separately.
May 1, 2022 · The usability of animal waste and by-products depends on their composition and a load of valuable elements. Table 1 present the elemental composition of various animal waste and by-products, which focuses on elements essential for plant growth. Due to the large variety, it is difficult to standardize the elemental content of various categories
Apr 15, 2020 · Previously, the domestic waste in rural areas was mainly kitchen waste, and the surplus kitchen waste was used to raise livestock, and the manure produced by livestock was mostly returned to the field as organic fertilizer (Xu et al., 2017). The construction of new socialist countryside has changed the traditional life mode in the countryside
Apr 15, 2023 · Due to its organic content, animal waste conversion to biofuel has become more popular over the past few decades. Around 25 % of solid waste and 10–15 % of liquid waste is generated from livestock industries. Animal waste quality relies on the waste digestibility, animal species and its age [1], [82]. Additionally, indigenous microbes found
Aug 1, 2023 · This review aims at providing comprehensive overview of the profiling of livestock wastewater from the dairy, swine and poultry sub-sectors along with the biological, physico-chemical, AI-based and integrated treatment methodologies, and valorisation for the generation of value-added products such as bioplastics, biofertilizers, biohydrogen and
Apr 15, 2021 · This study investigated the fate of antibiotic resistance genes (ARGs), metal resistance genes (MRGs), and class 1 integron-integrase gene (intI1) during thermophilic fermentation of swine manure in an ectopic fermentation system (EFS), which has been regarded as a novel system for efficiently treating both feces and urine.
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Feb 1, 2024 · Anaerobic digestion (AD) is used for the treatment of livestock waste or manure. Biogas fermentation, also known asbiogas technology or AD found to be an efficient waste management substitute because it produces renewable energy (methane), concurrently eliminating organic contaminants.
Mar 1, 2020 · Livestock and poultry farmers' livestock and poultry waste disposal are similar, but the probability of the livestock farmers adopting compost fermentation and direct return to treat livestock and poultry waste is greater than for the poultry farmers, as it is easier for the former to dispose of waste by discard randomly and fresh
Nov 29, 2023 · Anaerobic fermentation of organic waste, such as livestock manure, in biogas projects is an environmentally friendly and effective treatment method. The resulting biogas, mainly composed of methane, is a combustible gas with energy properties, while the digestate, containing nutrients such as nitrogen (N), phosphorus (P), potassium (K), and other organic matter, can be used for agricultural
Mar 19, 2024 · It features a mucosal immune system, including barriers and various immune cells, ensuring host defence (Malmuthuge 2017; Hooper et al. 2012). While many residing microbes are essential for host physiology, they also pose potential risks. The mammalian immune system maintains a balance with these microbes, ensuring mutual benefits.
