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
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.
Feb 29, 2024 · The lab-scale aerobic composting system used in this study includes the following five parts: reactor cabin, aeration pump, temperature sensor, heat exchanger, and data acquisition and control unit (Fig. 1). The reactor cabin was made of polypropylene with a height of 40 cm and an internal diameter of 37 cm, providing a working volume of 40 L.
Temperature. More than just composting: A Process to Further Reduce Pathogens. With aerated static pile composting, the pile temperature must exceed 55oC (131oF) for a minimum of three days to ensure pathogen destruction and to produce a safe product for unrestricted use on pastures and for sale into the community.
Jul 15, 2015 · Cattle manure UV-Vis, FTIR, Py-MS Vermicomposting Ge et al. (2015) Pig manure FTIR Composting Dairy manure UV-Vis, 13 C NMR Impact of organic farming Liu et al. (2015) Broiler litter, etc. FTIR
Feb 1, 2022 · of aerobic composting of solid manure: Performance and selection. In this study, static heap (SH) is chosen as the example of the most utilized original small farmer compost. Windrow composting (WC) is a common treatment procedure for intensive farms and fertilizer manufacturing industries.
Jan 1, 2024 · The initial material for the CCMC group was a mixture of chicken manure, mature compost, and rice husks. Chicken manure was collected from a local farm (Fuzhou, China), and kitchen waste was provided by the school canteen. The mature compost products were derived from the mature products of aerobic composting carried out by Tang et al. (2019
Jun 1, 2022 · The maximum oxygen concentration in SC was only 0.65% because the compost pile was in an oxygen-deficient environment during the aerobic composting with high moisture content and no turning (Amon et al., 2001). As a result, the methane concentration in SC was above 40% in the first five days and maintained 19.55% on day 40.
Dec 1, 2004 · Except temperature profiles, no significant difference was found during composting among the aeration systems. That is to say, the aeration systems could be all used in swine manure composting. But, the investment and operating costs of different aeration systems are significantly different (Table 4). It showed that active aeration system
Oct 7, 2022 · To ensure high performance of a composting process, optimum levels of moisture (40–60%), temperature (35–40 °C), particle size (3.1–12.7 mm), pH (5.5–8), and C/N (25:1–40:1) are required. Including components that take longer to compost, especially during co-composting, makes prolonged composting a challenge.
Apr 1, 2019 · Abstract With the aim to comparatively investigate the effect of the addition of additives such as biochar (BC), microbial inoculation (MI) and biochar/microbial inoculation (BCMI) on composting enhancement, nitrogen conservation, greenhouse gas emissions, the quality improvement of pig manure compost were comparatively investigated in a 42-day aerobic pig manure composting experiment. The
Dec 12, 2023 · On-farm composting takes place in the agricultural sector and may use a combination of crop residues, manure, straw, and other feedstocks generated on the farm to create compost. Farms may also choose to take in materials from residents or businesses in the surrounding community to increase their compost production or generate revenue in
Mar 15, 2018 · In this study, 100 mg/kg of amoxicillin (AMX) was added to pig manure during aerobic composting using a laboratory-scale reactor system, for better understanding the degradation of AMX and its potential risks. Qualitative and quantitative analysis of AMX and its main degradation products (DPs) were
Mar 15, 2020 · Here, we analyzed the fate of microbial communities and ARGs of cow manure treated by three conventional management strategies: aerobic composting, mechanical drying and precipitation, applying an integrated-omics approach combining metagenomics and metaproteomics.
2 days ago · Aerobic composting has been used as a mainstream treatment technology for agricultural solid waste resourcing. In the present study, we investigated the effects and potential mechanisms of the addition of a microbial agent (LD) prepared by combining Bacillus subtilis, Bacillus paralicheniformis and Irpex lacteus in improving the efficiency of cattle manure composting.
