“…Under the action of a strong oxidant, nitrogen is fixed as nitrate nitrogen, which is more stable [ 93 ]. Moreover, some studies also indicated that Fe 2 O 3 has satisfactory performance in reducing the volatilization of sulfur-containing odors [ 17 ]. With Fe 2 O 3 correction, the emissions of volatile sulfur compounds, such as COS, CS 2 , MeSH, and Me 2 SS, were reduced by 46.7–80.8%, but this still needs to be verified in further research.…”

“…To further improve the feasibility of safe composting and expand the production scale, it is necessary to take corresponding measures to mitigate GHG emissions. Additionally, the process of composting is accompanied by an unpleasant odor, which mainly originates from the volatile compounds containing sulfur and nitrogen [ 16 , 17 ]. Therefore, the construction of composting equipment and facilities should be improved to regulate the compost production conditions more strictly.…”

Composting is a promising technology for treating organic solid waste. However, greenhouse gases (methane and nitrous oxide) and odor emissions (ammonia, hydrogen sulfide, etc.) during composting are practically unavoidable, leading to severe environmental problems and poor final compost products. The optimization of composting conditions and the application of additives have been considered to mitigate these problems, but a comprehensive analysis of the influence of these methods on gaseous emissions during composting is lacking. Thus, this review summarizes the influence of composting conditions and different additives on gaseous emissions, and the cost of each measure is approximately evaluated. Aerobic conditions can be achieved by appropriate process conditions, so the contents of CH4 and N2O can subsequently be effectively reduced. Physical additives are effective regulators to control anaerobic gaseous emissions, having a large specific surface area and great adsorption performance. Chemical additives significantly reduce gaseous emissions, but their side effects on compost application must be eliminated. The auxiliary effect of microbial agents is not absolute, but is closely related to the dosage and environmental conditions of compost. Compound additives can reduce gaseous emissions more efficiently than single additives. However, further study is required to assess the economic viability of additives to promote their large-scale utilization during composting.

“…65 Feces acidification increases hydrogen ions, inhibits NH 4 + -N to NH 3 , and prevents nitrogen loss. 66 Kupper and Hani 67 showed that compared to the control group spring, summer, and autumn NH 3 emissions fell 66%, 44%, and 71%. Aboltins and Melece 68 conducted a metaanalysis of 89 literatures on greenhouse gas and NH 3 emission reduction in the process of livestock and poultry manure treatment and concluded that manure acidification can simultaneously reduce CH 4 , N 2 O, and NH 3 emissions.…”

Agriculture waste has increased annually due to the global food demand and intensive animal production. Preventing environmental degradation requires fast and effective agricultural waste treatment. Aerobic digestion or composting uses agricultural wastes to create a stabilized and sterilized organic fertilizer and reduces chemical fertilizer input. Indeed, conventional composting technology requires a large surface area, a long fermentation period, significant malodorous emissions, inferior product quality, and little demand for poor end results. Conventional composting loses a lot of organic nitrogen and carbon. Thus, this comprehensive research examined sustainable and adaptable methods for improving agricultural waste composting efficiency. This review summarizes composting processes and examines how compost additives affect organic solid waste composting and product quality. Our findings indicate that additives have an impact on the composting process by influencing variables including temperature, pH, and moisture. Compost additive amendment could dramatically reduce gas emissions and mineral ion mobility. Composting additives can (1) improve the physicochemical composition of the compost mixture, (2) accelerate organic material disintegration and increase microbial activity, (3) reduce greenhouse gas (GHG) and ammonia (NH 3 ) emissions to reduce nitrogen (N) losses, and (4) retain compost nutrients to increase soil nutrient content, maturity, and phytotoxicity. This essay concluded with a brief summary of compost maturity, which is essential before using it as an organic fertilizer. This work will add to agricultural waste composting technology literature. To increase the sustainability of agricultural waste resource utilization, composting strategies must be locally optimized and involve the created amendments in a circular economy.

“…Improper disposal of swine manure that contains abundant nutrients and organic substances can cause serious environmental pollution, such as contamination of ground and surface water and transmission of pathogenic microorganisms [2]. Anaerobic digestion (AD) is an environmentally friendly, efficient, and low-carbon-emission method for treating livestock and poultry manure [3]. AD not only allows degraded swine manure to be used as an agricultural fertilizer but also produces clean energy biogas that is fed into the natural gas network [4].…”

Biochar has attracted increasing attention as an additive for enhancing the performance of anaerobic digestion (AD), but the effect of biochar on microbial regulatory mechanisms in enhancing AD performance is unclear. To investigate how biochar modulates the process of AD, different inoculum sources including cellulose–peptone–swine inoculum (CPI) and swine manure inoculum (SMI) were designed to determine the effect of biochar on the performance and microbial communities of anaerobic digestion of the feedstock concentration from 1 to 6%. The results showed that the methane yields of CPI seeds were higher 20.3–38.7% than those of SMI seeds without a biochar addition, whereas the biochar addition reduced 5.3 and 23.1% of the corresponding methane yield of CPI and SMI, respectively. The biochar enhances the accumulation of volatile fatty acids (VFAs) and weakens the potential ammonia inhibition by adsorption, and it can improve the degradation rate of organic content of soluble COD for different inoculum sources. Microbial community analyses showed that the biochar addition could facilitate the growth of Bacteroidetes and Clostridiales, and it enriched the relative abundance of hydrogenotrophic methanogens Methanobrevibacter and Methanobacterium. Overall, although the modulation of biochar possessed different effects on the anaerobic digestion performance, it contributed to the stability and degradation efficiency of the digestion system. The recycling implication of biochar is critical to realizing a low-carbon and renewable treatment system for organic wastes.
