Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation
Jan 1, 2024 · Aerobic composting is a reliable strategy for converting livestock and poultry manure into organic fertilizer, which can be applied to enhance soil organic matter and nutrients (Nguyen et al., 2023). However, aerobic composting is hindered by low compost maturity due to incomplete decomposition.
Nov 1, 2009 · Mahimairaja et al. (1994) found a N-loss of only 11.2% during 12 weeks of composting of poultry manure and maize straw, while the losses accounted for 25.5% of total-N in composting of poultry manure and cotton waste (Paredes et al., 1996).
Sep 1, 2022 · The SEM dynamic analysis confirmed that TCS was involved in this dynamic process. TOC is an essential nutrient for microbial growth and directly affects bacterial composition in composting systems. In aerobic composting of chicken manure with AMX, SEM analysis found that TOC significantly affected TCS and negatively affected community 1 (Fig. 5
The Earth Flow system provides optimum conditions for hot, aerobic composting. This dramatically reduces the time required for horse manure composting from 6-12 months to 10-14 days (additional curing time of 1-2 months is recommended after the primary In tank composting phase is complete).
Oct 7, 2022 · Aerobic composting. Aerobic composting is the most effective method of decomposition, resulting in mature compost in a short period (USEPA 2021).It is the biological breakdown and stabilization of organic materials under the circumstances conducive to thermophilic microbe multiplication and activity, resulting in a stable, pathogen-free product suitable for agriculture and forestry (Mehta and
Composting is an aerobic microbial process in which organic materials, such as animal manures, yard trimmings, food waste and crop residues are decomposed to create a stable, humus-like
Aerobic composting as an effective cow manure management Mar 15, 2020 · Livestock manure is considered as an important source for spreading antibiotic resistance genes (ARGs) into the environment, and therefore poses a direct threat to public health.
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Jan 20, 2021 · This article provides a comprehensive review on aerobic composting remediation of soil contaminated with total petroleum hydrocarbons (TPHs). The studies reviewed have demonstrated that composting technology can be applied to treat TPH contamination (as high as 380,000 mg kg −1) in clay, silt, and sandy soils successfully.
Under federal organic standards, certifiers may require testing of manure or compost if there is reason to suspect high levels of contamination. Weed seeds and plant diseases can be effectively controlled by high temperature aerobic composting of manures. Manure Handling: Raw Stacked or Composted
Nov 27, 2023 · Aerobic composting is an effective method of resource treatment for agricultural and forestry solid waste; however, while wheat straw is usually used as a conditioner and is not the main body as in aerobic composting, wheat straw is abundant in annual production, and fertilization is one of the main ways of resource utilization of wheat straw, how to use wheat straw as the main body of aerobic
This study aims to design an aerobic composting system with dynamic aeration, investigate the effects of dynamic aeration on the temperature rise and physicochemical characteristics during the aerobic composting of corn straw and pig manure, and optimise the control parameters of oxygen concentration.
Nov 17, 2021 · 3 to 5% extra total mixed ration (TMR) diet is required as residuals in dairy farms according to industry standards that are common around the world and a large amount of cow manure is produced as daily waste in dairy farms. Aerobic fermentation using waste TMR with cow manure can not only control environmental pollution problems, but also produce high-quality fertilizer in low cost. We
Feb 20, 2022 · Therefore, the compost products quality of two-stage aerobic composting of blue-green algae sludge, pig manure and rice straw were stable and reliable. Table 1 . Summary of technical indexes of the Chinese Agricultural Organic Fertilizer Standard (NY525-2012) and final compost products from different batches of continuous operation within six
