Summary: Global living standards are improving, but global warming poses challenges. Composting is an effective strategy for reducing greenhouse gas emissions, but it also results in greenhouse gas emissions. Currently, there is no summary of methods to reduce greenhouse gas emissions during composting.

Summary: In a 42-day microcosm experiment, we found that nanoplastics have significant effects on soil microbial community structure, nitrogen removal processes, greenhouse gas emissions, and ecosystem multifunctionality. Positively charged nanoplastics have a stronger impact on soil microbial community structure and functions. Nanoplastics at environmentally realistic concentration inhibit soil denitrification but enhance anammox. Nanoplastics decrease soil N2O flux, while increasing CO2 and CH4 emissions. Nanoplastics can increase ecosystem multifunctionality but also increase greenhouse gas emissions.

Summary: Wheat is a crucial crop for global food security, however, boosting wheat yield on current cropping areas may not be enough to meet future global food demands. Climate warming has allowed wheat to be cultivated in previously uncultivated areas at higher latitudes. However, growing wheat in these regions presents several challenges, including the release of greenhouse gases. It is crucial to conduct research and develop wheat production techniques that minimize environmental damage in high latitude areas.

Summary: This study successfully simulated the variability of CO2 residue using a machine learning model and found that cumulative temperature anomaly plays a key role in the simulation. The model shows reasonably good agreement with observations for regional sites and global mean CO2, but has limitations in capturing spikes.

Summary: Global land use changes to meet the food demands of a growing population are turning agricultural soils into carbon sources. Effective agricultural management practices are crucial to offset anthropogenic carbon emissions, with carbon sequestration in agriculture being a viable option. Agroforestry is seen as the most promising approach, while strategies like no-tillage are considered less advantageous.

Summary: This study investigated the effects of different amounts of superphosphate (SSP) on greenhouse gas emissions and the dynamic changes in nutrients during pig manure composting.The results showed that the addition of SSP had no negative effect on organic matter composting, and all treatments met the requirement of being harmless.Adding 6% SSP to pig manure compost effectively reduces NH3 and CO2 emissions and improves compost quality.

Summary: This study investigated the effects of continuous application of biochar and organic fertilizer on global warming potential (GWP), greenhouse gas intensity (GHGI), and crop yield in a saline-alkali farmland in northern China. The results showed that both biochar and organic fertilizer reduced greenhouse gas emissions, but biochar had a greater effect and also increased crop yield and improved soil quality.

Summary: The study found that the use of phosphogypsum, EDTA, ammonium sulfate, and magnesium peroxide can significantly reduce methane and nitrous oxide emissions from rice fields, decrease the global warming potential, and increase grain yield without any yield penalty. More research is needed to evaluate the impact of these chemicals on food security.

Summary: This article studied the generation and monitoring methods of greenhouse gases during composting. By monitoring the changes in oxygen, carbon dioxide, and temperature, it was concluded that composting is mainly aerobic fermentation. Photoacoustic spectroscopy technology can effectively identify and quantify greenhouse gases N2O and CH4.

Summary: Irrigation with marginal quality water alters soil carbon and nitrogen cycle and affects soil greenhouse gas emissions. Reducing the salinity of irrigation water from 5 to 2 g L-1 can mitigate soil greenhouse gas emissions and address water resource scarcity.

Summary: Composting can divert organic waste from landfills, reduce landfill methane emissions, and recycle nutrients back to soils. However, the composting process is also a source of greenhouse gas and air pollutant emissions, and reported emission factors are difficult to interpret and highly variable.

Summary: The study aimed to investigate the impact of Cornstalk on greenhouse gas emissions and bacterial diversity during composting, finding that adding Cornstalk reduced emissions of N2O, CH4, and NH3 while increasing CO2 emissions. The amendment also affected the mineralization of carbon and nitrogen, with potential for efficient recycling of immature manure.

Summary: The study found that adding bamboo biochar can reduce greenhouse gas emissions during sewage sludge composting, while different bacterial agents have varying effects on emissions. The nitrous oxide emissions are closely related to bacterial communities, with strong negative correlations with certain bacteria groups.

Summary: This study assesses the CO2 levels in India using ground-based and satellite measurements. The results show that the average annual increase in CO2 concentration in India is 2.1 ppm, with the highest trends observed in areas of mines and refineries. The CO2 trends in India are comparable to global tropical and mid-latitude regions.

Summary: The meat and dairy industry in Europe relies on grass production, but there is potential to use grass for producing alternative products like polyhydroxyalkanoates (PHA) due to pressures to reduce agriculture's environmental impact, potential decrease in meat and dairy consumption, and the need to lower food production costs. Research shows that utilizing grass as a carbon source for PHA production could lead to a viable future option with reduced energy demand and improved efficiency through process optimization.

However, diverse interpretations and assessments of its potential benefits hinder progress. This study synthesizes policy-relevant lessons and research directions for a sustainable circular economy and identifies three narratives that underpin the ambiguity in assessments.
