Rust – proof commercial composting machine for reducing greenhouse gas emissions

2023/11/1/ · Previous studies have shown that different kinds of manure directly affect gas emissions during composting due to their different characteristics and microorganism communities. For example, Wan et al. (2021) demonstrated that higher values of pH, NO 3 −-N, total C (TC) content, and C/N ratio were found in sheep and cattle manure composts, whereas

2024/11/1/ · The amounts of gases emitted from composting are key to evaluating global warming potential (GWP). However, few can accurately predict the quantities of relevant gas emissions. In this study, three developed machine-learning models were used to

2017/1/1/ · Greenhouse gas emissions and compost chemistry were monitored at a northern California compost facility (latitude 38.77564 N, longitude 121.88007 W). The green waste material, comprised of yard trimmings collected from surrounding cities north of San

method is suitable for measuring GHG emissions from composting facilities. The total emissions were found to be 2.4±0.5 kg CH 4-C Mg-1 wet waste (ww) and 0.06±0.03 kg N 2 O-N Mg-1 ww from a facility treating 15540 Mg of garden waste yr-1, or 111±30 kg 2

2020/4/15/ · Compared with the values in open composting, BSFL bio-treatment of food waste could lead greenhouse gas (especially CH 4 and N 2 O) and NH 3 emissions to decrease. Therefore, a higher pH value of the substrate can increase the larval output and help the mitigation of greenhouse gas emissions.

Previous studies revealed that superphosphate fertilizer (SSP) as an additive in compost can reduce the nitrogen loss and improve the effectiveness of phosphorus during composting. However, few studies have explored the influence of adding SSP with high levels on ammonia and greenhouse gas emission

2024/11/28/ · The rapid increase in the population, urbanization, increasing standard of living, indifference, and other factors can be used to explain the concerning rate of waste generation. Research suggests that most countries prefer to process and dispose of their waste via open dumping or landfilling due to its affordability and simple mechanism. However, leachate and

2025/1/15/ · The construction of Fenton-like reactions has been shown to stimulate HA production in agricultural waste composting by generating hydroxyl radicals (•OH) [5].Among the materials that provide H 2 O 2 for the Fenton-like reaction, calcium peroxide (CaO 2) has received widespread attention due to it can release H 2 O 2 slowly and effectively minimize the

2022/11/10/ · With the rapidly broadening development of living standards, the global demand for meat products has markedly increased, which consequently has led to the generation of large amounts of livestock manure. Approximately 3.8 × 10 10 tons of livestock manure and 1.0 × 10 9 tons of crop straw are produced annually in China, of which 70 % are comprehensive

2023/9/1/ · The attenuated denitrification process led to a 1.51-fold increase in the total nitrogen content and a 27.47% reduction in N 2 O emissions. Overall, adding siderophores is an efficient strategy to reduce greenhouse gas emissions and promote the compost quality.

2020/2/1/ · This research investigated the influence of biochar (B) and bean dregs (BD) amendments on carbon and nitrogen losses through greenhouse gas (GHG) emissions during pig manure (PM) composting. The treatments included 15% BD, 10% B and 15% BD+10% B (w/w dry basis of PM) amendments in the compost, whereas the CK (control) lacked any additives.

2023/4/28/ · 3.2.5 Total greenhouse gas emissions Total GHG emissions over the 143 days of composting amounted to 6280−8076 g CO 2-C eq m −2 (Table 1). We did neither observe a significant BC effect nor an effect of the type of manure used on total GHG emissions1).

2024/2/10/ · The most fundamental reason for the effect of biochar on GHG emissions is the interaction of biochar physicochemical properties with soil and soil microorganisms. Li et al. (2018) summarized the effects of biochar on soil GHG emissions in forest ecosystems and showed that the application of biochar in forest soils typically improved soil physical properties (e.g., soil

2024/7/1/ · Composting is a crucial method for effectively utilizing and safely treating livestock and poultry manure (Fan et al., 2021, Zhang et al., 2020). Various composting techniques have been developed to improve the composting process, reducing greenhouse gas

2024/5/1/ · Aerobic kitchen waste composting can contribute to greenhouse gas (GHGs) emissions and global warming. This study investigated the effects of biochar and zeolite on GHGs emissions during composting. The findings demonstrated that biochar could reduce N 2 O and CH 4 cumulative releases by 47.7 %and 47.9 %, respectively, and zeolite could reduce the …
