Jul 30, 2021 · Recycling livestock manure provides energy and prevent pollution, yet actual transformation processes are limited in terms of performance and cost. Here, we review inorganic additives used to improve anaerobic digestion. Additives include minerals such as zeolite and magnetite, metals such as bulk and nanoparticles, industrial wastes, and pH-regulating additives. We focus on microbial
Feb 23, 2021 · Livestock manure is one of the main sources of agricultural nonpoint source pollution and poses a great threat to the environment and human health. Sustainable management of manure via recycling is an effective means to tackle the problem. Based on field interviews in China, multiple case studies were employed to investigate alternative manure management systems. Four conclusions arose. First
Jul 30, 2024 · Solid storage can be part of a manure management system with solid-liquid separation or manure drying but combining these practices is not required. Best Use Cases: Suitable for any animal type. Typical in colder climates; covered facilities can aid with snow and rainfall events.

Jul 1, 2024 · This study investigates methane emissions from the livestock sector, representing by enteric fermentation and manure management, in Egypt from 1989 to 2021, focusing on spatial and temporal
Dec 15, 2022 · The major GHG emissions from livestock systems in the GLEAM model are: (1) CH 4 emissions from enteric fermentation in ruminants and pigs; (2) CH 4 emissions arising from manure management; (3) N
Jun 22, 2024 · The Inner Mongolia Autonomous Region is a crucial area in China with a significant advantage in animal husbandry, particularly in cattle and sheep farming. However, the disposal of the large quantities of manure produced during farming has severely impacted the industry’s healthy development. Proper treatment of the manure can convert it into organic fertilizer beneficial to farmland
May 2, 2023 · Anaerobic digestion of animal manure results in the production of renewable energy (biogas) and nutrient-rich biofertilizer. A further benefit of the technology is decreased greenhouse gas emissions that otherwise occur during manure storage. Since animal manure makes anaerobic digestion cost-efficient and further advance the technology for higher methane yields, it is of utmost importance to
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
Sep 1, 2024 · In present study, firstly, a heat pump system was designed to utilize the heat generated from aerobic fermentation of cattle manure (CM) and rape straw (RS) as heat source. The interrelationship between the temperature of the materials and the performance of the heat pump was explored.
May 13, 2012 · From the point of view of biogeochemistry, manure is a complex of organic matter containing minor minerals. When manure is excreted by animals, it undergoes a series of reactions such as decomposition, hydrolysis, ammonia volatilization, nitrification, denitrification, fermentation etc., from which carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ammonia (NH3) can be produced
Livestock manure In 2018, livestock manure deposited annually on agricultural soils was largest in Asia (40 million tonnes N, up 50 percent since 1990), followed by the Americas (30 million tonnes N, up 20 percent) and Africa (also 30 million tonnes N, however it doubled since 1990). Conversely in Europe
5 days ago · Microbe-aided thermophilic composting accelerates manure fermentation. Aerobic composting is a key strategy to the sustainable use of livestock manure, which is however constrained by the slow kinetics. Microbe-aided thermophilic composting provides an attractive solution to this problem.
Aug 22, 2021 · The results showed that the addition of biochar had different effects on anaerobic fermentation of livestock and poultry manure with high solid concentration, increased the content of CH4 and decreased the content of H 2 S. the addition of biochar provided enough granular surface to absorb a large number of inoculated microorganisms, which
