Jan 20, 2022 · Three open-air composting piles (10 m 3) using the turning composting system were established at Miguel Hernández University (Orihuela, Alicante, Spain). The piles were composed of different proportions of agro-industrial wastes (dry weight basis), as follows: Pile A: 47% vineyard pruning waste, 34% tomato waste and 19% leek waste; Pile B: 54%
Feb 15, 2018 · A total of 109 ARGs were detected in the manure and compost samples, thereby demonstrating that both are important ARG reservoirs. The diversity and abundance of ARGs were significantly higher in chicken and pig manure than bovine manure, but industrial composting was more efficient at reducing the ARGs in chicken manure than pig and bovine manure.
Jun 1, 1999 · Dairy cattle and pig manure mixed with sphagnum peat and a little barley straw was composted in a continuously working horizontal drum composting system in three successive series. Changes in microbiological and chemical parameters were monitored during the six days' processing in the drum and the subsequent three months' curing in heaps.The temperature of the composting mass in the middle of
Dec 1, 2022 · In this work, the removal of antibiotic resistance genes (ARGs) in the industrial-scale pig manure management system has been investigated. Additionally, the implications of mobile genetic elements (MGEs) and microbial community structure have been discussed. During the whole period of manure management, 19 ARGs and 7 MGEs were obtained from
Jun 1, 2021 · The composting efficiency was analysed by the impact of rice husk biochar amendment (0, 2, 4, 6, 8 and 10%) in the presence of salts for the co-composting of food waste and swine manure, in composting reactors for 50 days. Results revealed that biochar amendment had improved the degradation rates by microbial activities in comparison with control.
Nov 11, 2023 · The concept of recycling organic matter and waste nutrients back to agricultural land through the process of composting adheres to the basic principle of the circular economy. The studies on composting systems have laid a solid foundation for biodegradable solid waste management, and there are still significant gaps that require attention in future research. Addressing these gaps will lead to
Jan 1, 2002 · The temperatures of composting materials typically follow a pattern of a rapid increase to 120 – 140° F (49 - 60° C) which is maintained for several weeks, a gradual temperature decrease to 100° F (38° C) as active composting slows due to nutrient consumption, and a final leveling off at ambient air temperature.
Jan 14, 2022 · Composting is an important technology used to treat and convert organic waste into value-added products. Recently, several studies have been done to investigate the effects of microbial supplementation on the composting of agro-industrial waste. According to these studies, microbial inoculation is considered to be one of the suitable for enhancing the biotransformation of organic
If you want to compost animal manure (such as composting pig manure, cow dung composting and horse manure composting), you need to do the following works, including collect manure (and bedding) from barn, make a compost pile and turn them regularly until fermentation finishes. The detailed process is as below:
Composting is an effective manure management tool that reduces volume, kills pathogens, kills parasites and reduces weed seeds, and also improves soil health and fertility. However, soil and compost should be tested for nutrients.
Nov 20, 2023 · DOI: 10.1016/j.biortech.2023.130079 Corpus ID: 265335904; Responses of greenhouse gas emissions to aeration coupled with functional membrane during industrial-scale composting of dairy manure: Insights into bacterial community composition and function.
Dec 1, 2022 · In this study, we used both chicken and pig manure as the main composting substrates and applied biochar to construct multiple industrial-scale composting systems for processing.
Apr 30, 2024 · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk. In this study, the effects of process
Oct 15, 2023 · In a study evaluating the impacts of bentonite on nutrients transformation during the pig manure composting, OM contents were observed to decrease with the increasing amount of bentonite added (Li et al., 2012). This confirmed that OM content in the pig manure was diluted by the addition of bentonite containing negligible OM (Table 1).
Sep 5, 2023 · Different of Pig Waste Management. One common method is lagoon systems, which involve storing the manure in large open-air ponds. This allows for the natural breakdown of the manure through anaerobic digestion, but it can also lead to odor issues and potential pollution if not properly managed.
