Apr 4, 2022 · A small percentage is occupied by energy of workers (1.7%). It is established, that at the production of compost from manure of cattle consumption of energy, in particular diesel fuel and human
Jan 20, 2018 · A sound biowaste management is a promising solution towards post-fossil carbon societies (Mihai and Ingrao, 2016), as it is characterised by good levels of energy, economic and environmental performance. In this context, manure composting can be considered as a solution to break down the aforementioned environmental impacts and other related ones.
May 1, 2020 · Factors affecting gaseous emissions, maturity, and energy efficiency in composting of livestock manure digestate. May 2020. Science of The Total Environment 731:139157. DOI:
The decrease in volume reduces hauling costs. Wiederholt et al., (2009) conducted a case study that compared the energy required of a 180-head feedlot operation that applied raw manure and composted manure to agricultural fields. They concluded that composting and applying livestock compost is more energy efficient than hauling raw manure.
Jan 26, 2022 · Manure is an organic fertilizer made from the dung of domestic livestock including horses, cows, and poultry. It may also contain urine and bedding material like straw or sawdust. Manure is an
Apr 11, 2023 · Composting is an ecological and economical alternative for organic waste treatment, which turns manure into fertilizer/organic amendment . Composting is not considered a new technology, but among the waste management strategies this method is considered a suitable option for manure management due to the economic and environmental benefits [ 26 ].
Apr 15, 2022 · Instead of being burned, the massive agricultural waste(s) can also be composted. Composting is the regulated biodegradation (microbe-mediated transformation) of animal and plant materials (organic waste) under aerobic conditions, where organic matter is broken down into smaller biodegradable components that can be used to improve crop growth and yield (El-Hagga et al., 2004; Sanchez et al
Dec 15, 2023 · Composting is the controlled, aerobic (oxygen-required) biological decomposition of organic materials by microorganisms. Organic (carbon-based) materials include grass clippings, leaves, yard and tree trimmings, food scraps, crop residues, animal manure and biosolids. Compost is a dark, crumbly, earthy-smelling, biologically-stable soil
manure (swine, poultry, dairy). With these variables, loss of N can range from 5-60%.2 Compost is a solid material with a consistency similar to manure, so it can be applied to fields with a spreader. A lab analyses of compost is necessary to determine nutrient content and land application rates. The results of research on composted manure as a
Aug 20, 2020 · This study investigated the interplay effects of key operational factors on maturity, gaseous emissions, and energy efficiency during composting of livestock manure digestate. Orthogonal experiments were conducted with three factors: digestion duration (15, 30, 45 days), corn stalk addition (15%, 25%, 35%, wet weight based), and aeration rate
Feb 1, 2022 · It reduces the redundancy of composting machinery, improves composting efficiency while ensuring the quality of composting products. Therefore, in view of the increasing demand for expanding intensive breeding and resource utilization of livestock and poultry manure, RC is an optimal solid manure composting method with low environmental costs

Oct 1, 2023 · Hence, using anaerobic digestate as a biofertilizer is a common practice in sustainable agriculture. The digestate quality was equivalent to other biofertilizers such as compost manure from aerobic composting and vermicomposting (Isha et al., 2020; Vijay et al., 2021a; D’ Silva et al., 2022b). But the quality of anaerobic digestate is
Apr 10, 2023 · Several factors increase the costs of using manure as a commercial fertilizer replacement. First, manure has a low nutrient value-to-mass ratio. This is partly because of its water content, which can be up to 90 percent of the total weight. The low quantity of nutrients per ton makes manure application and transportation time-intensive and costly.
