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

There are many ways to compost livestock mortalities. However, there are a few basics that are universal to all systems. Well-managed composting provides aerobic (oxygen-loving) microorganisms with the proper environment to grow and rapidly break down the mortality.

Mar 24, 2024 · An optimal balance of nitrogen (from chicken manure) and carbon (from materials like leaves or straw) facilitates aerobic decomposition. The carbon-to-nitrogen ratio (C) should be maintained around 20-30:1 for effective composting.

Sep 28, 2023 · Composting chicken manure is a cost-effective and eco-friendly way to create nutrient-rich soil for gardening. By breaking down the manure through composting, you can eliminate pathogens and odors while producing a valuable fertilizer that can improve soil structure and promote healthy plant growth.

Closed composting systems mainly can be divided into reactor composting systems, semipermeable membrane-covered composting systems, and greenhouse composting systems. A reactor composting system is environment-friendly and high-efficiency, but it has a high cost and a limited processing capacity (Ajmal et al. 2020).

Jul 18, 2020 · Composting is an integral part of waste management. In tank composting makes for a more efficient compost within a short period. Composting allows the transformation of waste into a useful product. However, the processes involved and the end product can differ concerning quality, performance, or safety. Composting, an exothermic process, is majorly regulated by temperature monitoring. Models

Abstract. Composting technology comprising hyperthermophilic pretreatment (at ≥85 °C for 2 to 4 h, HTPRT) and aerobic composting was adopted to accelerate organic matter transformation and enhance nitrogen retention in chicken manure composting.

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.

During the composting process, microorganisms degrade organic material such as dry poultry excrement, broiler manure or separated slurry in an aerobic environment. The dry matter content should be at least 30 percent. The final product is compost: a valuable, organic fertilizer that has good plant

Jan 1, 2024 · EFAC is superior to traditional composting and provides a novel strategy for co-composting and disposal of poultry manure and kitchen waste. This EFAC system can be applied to large-scale waste management by splitting a large composting system into several smaller systems.

Feb 21, 2024 · Proper composting treatment of poultry manure waste is recommended before its use as a fertilizer. This involves many bioprocesses driven by microorganisms. Therefore, it is important to understand microbial mechanisms behind these bioprocesses in manure composting systems. Many efforts have been made to study the microbial community structure and diversity in these systems using high

Feb 1, 2024 · Aerobic composting was conducted using substrate that consisted of maize straw, chicken manure, and mushroom residues for 15 d. The substrates were purchased from Sichuan Haolong Agricultural Development Co., Ltd. (Meishan, China). The maize straw was shredded, and the straw was 0.5–1 cm long.

Aug 1, 2023 · The production of organic fertilizer by aerobic composting of cattle manure is an important way of its resource utilization. This study evaluated the effects of adding mature compost on the decomposition and microbial communities in the aerobic composting of cattle manure.

Oct 1, 2020 · Introduction. The continuous expansion of animal husbandry and intensive poultry breeding generates a large amount of livestock manure, which results in serious environmental and economic problems if it is not effectively managed (Bluemling and Wang, 2018).

Oct 1, 2017 · In recent years, microbial-based aerobic composting has become an important means to efficiently degrade organic matter and nutrients included in poultry manure, reduce and detoxify waste stockpiles, and maximize resource utilization efficiency (Awasthi et al., 2016, Zhang et al., 2016).
