rapid composting system for livestock waste

Feb 1, 2024 · Introduction. In recent decades, owing to rapid population growth, a large amount of solid waste has been generated, becoming a global concern. According to the World Bank, the generation of municipal solid waste is expected to reach 3.4 billion tons annually by 2050 (Nanda and Berruti, 2021), of which organic waste accounts for the major part, at approximately 46% (Yang et al., 2015).

Aug 23, 2023 · The strategy can be applied not only to composting and recycling livestock waste but also to handling pathogen-contaminated healthcare waste generated by hospitals [25,26,27,28,29]. This study has some limitations, including cases where pathogens were not detected even in general soil, possibly due to pathogen leakage during the sample

Feb 20, 2014 · The livestock waste is major source of noxious gases, harmful pathogens and odor; hence, it has public health and environmental concern. Hence, livestock waste is to be managed properly to mitigate production of these pollutants in order to protect environment. Proper utilization of livestock waste into biogas, compost and vermicompost making can be very useful to increase crop yield and

Composting animal manures is an effective way to kill pathogens. Grewal (2006) studied and compared the length of time that pathogens lived in simulated composted dairy manure, a simulated dairy manure pack and a simulated liquid dairy lagoon.

Improved composting processes, such as hyperthermophilic temperature composting, could effectively remove ARGs, and the HGT of ARGs and the microbial communities are identified as vital influencing factors. 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

Nov 25, 2020 · The chapter discusses various aspects of composting via analysis of the integrated waste management system and composting-related projects implemented at the community level in the Indian context.

Feb 1, 2018 · In composting systems using livestock wastes, the acquisition of bulking agents and the facilities construction were more than 60% of the total production costs (Table 6). On the contrary, in composting systems based on crop residues, the collection of such material was the more expensive operation (Table 6). Even if costs can seem high (if the

For livestock operations larger than 1000 head, a National Pollution Discharge Elimination System Permit is needed. If compost is sold, a siting permit is needed. If livestock waste is combined with landscape waste and exceeds greater than 10 percent of the total volume, an EPA organic waste-composting permit is required.

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

Apr 1, 2014 · This study was aimed at determining whether CH4, N2O, and NH3 emissions from composting are affected by bulking agents during rapid composting of pig manure from the Chinese Ganqinfen system. Three bulking agents, corn stalks, spent mushroom compost, and sawdust, were used in composting with pig manure in 60 L reactors with forced aeration for

Nov 15, 2017 · Compost technology is an advanced technology that involves the transformation of organic materials and organic waste/sludge into organic manures/fertilizers.

Mismanagement of the composting process can result in emissions of CH4, N2O, and NH3, which have caused severe environmental problems. This study was aimed at determining whether CH4, N2O, and NH3 emissions from composting are affected by bulking agents during rapid composting of pig manure from the Chinese Ganqinfen system. Three bulking agents, corn stalks, spent mushroom compost, and

Awasthi et al. (2015), showed that co-composting of the organic fraction of municipal solid waste (OFMSW) with wood as bulking waste, generated a well matured compost within 28 days. Likewise, Silva et al. (2016) used carbon sources and wood chips as bulking agents and assessed the feasibility of co-composting on the quality of poultry manure

Oct 26, 2021 · 3.1 Selection of IoT Gateways. Considering the scenario of multiple composting units located in a locality, an IoT-based integrated data management system can handle the entire data received from the multiple sensor nodes from multiple smart composting bins/piles and can process the same through suitable system architecture models (Fig. 2).

May 30, 2020 · Composting is the controlled conversion of degradable organic products and wastes into stable products with the aid of microorganisms. Composting is a long-used technology, though it has some shortcomings that have reduced its extensive usage and efficiency. The shortcomings include pathogen detection, low nutrient status, long duration of composting, long mineralization duration, and odor
