Jul 27, 2021 · More broadly, by reducing food waste, composting also helps to reduce greenhouse gas emissions that affect climate change. Food loss and waste generate an estimated 8-10 per cent of global greenhouse gas emissions while using land and water resources increasingly put pressure on biodiversity.
Composting . There are many of composting organic materials (Figures 1 and 2).These include active windrow (with turning), passive composting piles, passively aerated windrow (supplying air through perforated pipes embedded in the windrow), active aerated windrow (forced air), bins, rectangular agitated beds, silos, rotating drums, containers, anaerobic digestion, and
May 20, 2020 · Corn stalk addition of 25% and aeration rate of 0.24 L kg-1 DM min-1 could ensure desirable compost maturity and save energy consumption. Thus, digestion for 30 days, 25% corn stalk addition, and aeration rates of 0.24 L kg-1 DM min-1 can be potentially implemented in industry for environmental and cost efficient composting of digestate.
Aug 16, 2023 · Specifically, all else being equal, an improvement in the index of economic complexity by 1% increases energy efficiency by 0.1880–0.1744%. The developed economic complexity index increases energy efficiency due to advanced technology and skilled labour.
Dec 15, 2023 · Composting is the controlled, aerobic (oxygen-required) biological decomposition of organic materials by microorganisms. Organic (carbon-based) materials include grass clippings, leaves, yard and tree trimmings, food scraps, crop residues, animal manure and biosolids. Compost is a dark, crumbly, earthy-smelling, biologically-stable soil
Feb 1, 2022 · However, the impact of the composting facility and energy input on eco-efficiency is limited. In this study, a LCA approach was conducted to investigate the eco-efficiency of four widely applied composting strategies: static heaps (SH), windrow composting (WC), membrane-covered composting (MC) and reactor composting (RC).
Dec 1, 2023 · Waste to Energy (WtE) technologies comprises a group of techniques that convert waste into useful forms of energy, such as heat, electricity, and alternative fuels like biogas (Moya et al., 2017; Soltani et al., 2016) (Fig. 3). These techniques include incineration, co-processing, anaerobic digestion, landfill gas collection, and pyrolysis
Jan 1, 2022 · Composting economics refers to the business of composting—how to manage feedstocks and manufacture a marketable product in such a way as to produce a profit. It is essentially about making sure revenues and savings exceed the cost of production. Composting revenue comes primarily from fees collected to treat feedstocks (gate or tip fees) and
Feb 8, 2024 · With the increase of organic solid wastes (OSWs), current waste management practices, such as landfill, incineration, and windrow composting, have shown weaknesses in both resource recycling and environmental protection. Co-composting has been used to achieve nutrient and carbon recycling but is accused of high ammonia emission and low degradation efficiency. Therefore, this study developed a
Sep 7, 2022 · The use of waste from the production chains as energy sources is the most efficient mechanism to promote change in the sector toward sustainability of livestock production since biogas is a vehicle for bioeconomy and bioenergy, closing the cycles of the chain and thus ensuring circularity (Awasthi et al. 2019; Diamantis et al. 2021).
Jun 12, 2023 · The energy yield was increased by increasing the oxygen content by 21%. The maximum hydrogen yield, hydrogen and carbon gasification efficiency of supercritical water chicken manure gasification reached up to 22.47 mol/kg, 174.53 and 81.34%, respectively, at a temperature of 620 °C and reaction time of only 12 min(Cao et al. 2022). The co
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
Aug 29, 2018 · It also leads to up to 50–60% of reduction in the volume and density of manure thereby making its transportation more energy efficient than that of non-composted manure . Anaerobic digestion: Anaerobic digestion of manure is the processing of manure to produce energy, mainly biogas. Anaerobic digestion of manure can be made more efficient
