Mar 1, 2009 · The effects of three different mixtures of organic waste on composting in a rotary drum were examined by measuring changes in physico-chemical and biological parameters. It was observed that the time courses of the three mixtures: run A (grass cuttings, vegetable waste and food waste), run B (cattle manure, vegetable waste and sawdust) and run
Apr 21, 2022 · This optimized composting process increased the yield of organic fertilizer by 331 Mg year −1 and the increased profit was 464,400 yuan·year −1. Improving the current composting process is conducive to improving the environmental and economic benefits of chicken manure composting in southwest China.
Composting reduces the volume and density of manure approximately 50-65% (Figures 1 and 2). The decrease in volume reduces hauling costs. Wiederholt et al., (2009) conducted a case study that compared the energy required of a 180-head feedlot operation that applied raw manure and composted manure to agricultural fields.
Apr 29, 2023 · Although aerobic composting leads to more nutrient loss from the waste, it is considered more efficient and beneficial for agricultural production than anaerobic composting (Cai et al. 2019; Mehta and Sirari 2018).

compost maturity. An optimum compost C:N ratio satisfies the protein requirement of the growing microbial community (nitrogen) as well as the energy requirement (carbon) for the breakdown of complex carbon into simple digestible forms. A good C:N ratio for an initial compost mix is 25-30 and a finished compost matches that of the
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
