2019/8/1/ · However, aerobic composting of livestock manure is usually accompanied by the production of greenhouse gases and other gases, including methane (CH 4 ), carbon dioxide (CO 2 ), nitrous oxide (N 2

2021/1/1/ · In this work, agricultural wastes were treated by composting in an ectopic fermentation bed system (EFBS) with a continuous nitrogen addition technique. With decreasing of NH 4 +-N concentration and increasing of NO 3 −-N concentration were observed, and activities of protease, urease and nitrate reductase changed significantly during the

2023/8/4/ · Chicken manure and composts derived from it are valuable organic fertilizers that have a positive impact on soil fertility and significantly enhance crop yields. However, the

Bio-conversion of organic waste using composting technologies 507 Tiquia, S.M., Tam, N.F.Y. and Hodgkiss, I.J. (1996) ‘Microbial activities during composting of spent pig-manure sawdust litter at different moisture contents’, Bioresource Technology, Vol. 55, No

Bolong March 2005, Vol. 46, No. 3, p. 25 Analysis of alternative – agitated bed, aerated static pile and modified tunnel – show that properly applied facility configurations with biofiltration would reduce odors to acceptable levels at Colorado site. Todd O. Williams and Stacey Servo ODOR GENERATION and impact on surrounding communities is a

2021/7/15/ · It has always been challenging to model gas emissions from MMSs due to the variability in farming practices that affect the manure physio-chemical characteristics (Owen and Silver, 2015). Intergovernmental Panel on Climate Change (IPCC) emission factors (Tier 1, 2, and 3) are widely used to predict gas emissions; however, in some studies (Lory et al., 2010; Owen

Manure piles collect underneath each barn often building to a depth of 40 to 50 centimeters (1.5 feet). The chicken manure is allowed to create a solid heap underneath the barns. The manure creates a tremendous odor problem and the compost is slow to

2024/9/1/ · Livestock manure is an important component of animal agriculture, playing a pivotal role in its sustainability, impact on climate change, and contribution to circular economy [1, 2].Livestock manure presents a double-edged sword. While it serves as a rich source of

2024/12/1/ · This study explored the odor composition and emission in chicken manure composting process, employing chemical fixatives and biochar to mitigate odors effectively.

2016/9/1/ · Odor pollution has become a hindrance in the promotion of compost technology in treating sewage sludge from industries (Anderson et al., 2009). Odor compositions are complicated and can be divided into volatile inorganic compounds (VICs) and volatile organic

2024/11/12/ · The above results demonstrate that mature compost addition into swine manure and carcasses could increase the relative abundance and the number of microbial taxa involved with organic matter degradation (e.g., Ureibacillus), providing an appropriate temperature and pH environment for driving composting maturity.

2014/11/18/ · Which is better for managing source separated organics, anaerobic digestion or aerobic composting? “It’s not an either-or proposition,” suggest the authors. Tom Kraemer and Scott Gamble Bolong November 2014
