Materials and Thermophilic composting process and sampling
Mar 24, 2022 · Solid-state fermentation has, over the decades, attained global recognition because of its potential to contribute significantly to solving some of the world's persistent problems, including malnutrition in humans and livestock, environmental pollution, climate change, hunger, and improving global food security (Ezekiel and Aworh, 2013; Zepf and Jin, 2013; FAO, 2016; Meybeck et al., 2018
Although antibiotics were originally used to treat livestock that have specific diseases, the vast majority of them are now used in industrial food animal production (IFAP) to prevent infections from various pathogens that infect the livestock due to their close living quarters, lack of clean living spaces, and weakened immune systems from lack
Aug 1, 2023 · The production of organic fertilizer by aerobic composting of cattle manure is an important way of its resource utilization. This study evaluated the effects of adding mature compost on the decomposition and microbial communities in the aerobic composting of cattle manure.
Providing anaerobic digestion is a prospective technology for utilizing organic waste, however, for waste with a high content of nitrogen such as manure, dilution is necessary to decrease the ammonia inhibition effect which leads to the production of a huge effluent amount which is difficult to use. Dry anaerobic digestion has some advantages such as reduced reactor volume, higher volumetric
Dec 6, 2023 · News Joint manure fermenter may help reduce ammonia and greenhouse gas emissions article_published_on_label December 6, 2023. Implementing a low-emission barn system, where sludge is removed daily to be fermented and stripped, could significantly reduce greenhouse and ammonia emissions in the dairy farming sector.

Apr 29, 2023 · However, the study eventually found that anaerobic fermentation of 175 kg of cattle manure with 175 kg of water and 50 kg of poultry manure with 325 kg of water produced 6.33 and 0.83 m 3 /day of biogas, respectively (Recebli et al. 2015).
Jul 1, 2022 · Composting is an effective and necessary modality in the recycling of agricultural wastes such as livestock manure, furfural, and straw. However, the risks of heavy metals (HMs) and antibiotic resistance genes (ARGs) during industrial-scale composting process have not been adequately assessed, espec
Jan 2, 2024 · One hundred fifty tons of liquid manure was fermented in a liquid manure tank by an air ring blower at 0.03–0.045 m 3-air/min·m 3, and 14 t of solid manure was fermented in a solid manure
the methane production stage and VS removal efficiency of 52.7% for the whole fermentation process were achieved. 1 Introduction As the amount of the large scale livestock and poultry farms increased in China, the discharged manure increased accordingly and the environment pollution caused by manure became prominent gradually in recent years.
Oct 8, 2020 · Recently, dry anaerobic co-digestion is one of the mechanisms which have been increasingly used to improve the reactor’s performance for treating livestock manure with agricultural crop residues. Due to carbohydrate, protein and lipid existing in agricultural wastes, biogas yield decreased with higher reactor volume when using wet anaerobic digestion. In this regard, the aim of this work was
Dec 15, 2022 · Manure management and enteric fermentation of livestock are the major contributors to climate change, accounting for 48% and 46% (3% by swine and 43% by ruminant), respectively.
Mar 22, 2023 · Improving manure management. Developing new uses and markets for manure may result in both economic and environmental benefits. The ERS report, Increasing the Value of Animal Manure for Farmers (AP-109, March 2023), uses data from the USDA Agricultural Resource Management Survey (ARMS) to describe current manure production, handling, storage
