“…Otherwise, the nitrogen content increases due to mineralization and the production of ammonium and nitrate [ 51 ]. Carbon serves as a source of energy, and nitrogen is needed to construct cell structures [ 31 , 58 ]. Azim et al [ 51 ] reported that the total nitrogen before composting is 1–4% of the total dry weight of compost.…”

“…The elements need to be in a certain proportion to maintain ordinary microbial turnover in order to produce a product of outstanding standards [ 31 ]. According to the literature [ 10 , 31 , 62 ], the optimal C/N ratio for composting is between 25 and 30:1 for all types of organic waste, but the ratio between 20 and 40:1 is also acceptable [ 63 ]. For microorganisms to develop quickly and to guarantee adequate energy consumption, the ratio should be approximately thirty [ 51 ].…”

“…The main advantages of this system are low cost and simple operation, but on the other hand, it is difficult to control the process variables which makes the composting time longer. The closed systems have advantages over the open ones: they take less space and provide better control of the process, which leads to high efficiency of the process [ 30 , 31 ].…”

Within the various approaches to organic waste handling, composting has been recognized as an acceptable method to valorize organic waste. Composting is an aerobic technique of microbial disruption of organic matter which results with compost as a final product. To guarantee the quality of the compost, key process factors (like the moisture content, temperature, pH, and carbon-to-nitrogen ratio) must be maintained. In order to optimize the process, nine composting trials using grape skins were conducted in the present study under various initial moisture content and air flow rate conditions over the course of 30 days. The processes were monitored through physicochemical variables and microbiological activity. Also, the kinetics of the organic matter degradation and microbial growth were investigated. Although the thermophile phase was only achieved in experiments 3 and 8, the important variables proved the efficiency of all nine composting processes. The organic carbon content and C/N ratio decreased after the 30 days of composting processes and a great color change was noticed too. The values for the germination index for all experiments were above 80%, which means that the final products are non-toxic for plants. Also, the greatest change in organic carbon content in was evident in experiment 3; it decreased from 71.57 to 57.31%. And consequently, the rate of degradation for that experiment was the highest, at 0.0093 1/day. Furthermore, the response surface methodology was used to identify optimal operating conditions for grape skin composting and the obtained conditions were 58.15% for the initial moisture content and 1.0625 L/min for the air flow rate.

“…71 Adding more than 10% of the dry weight (more than 4% of the wet weight) of calcium super phosphorus to pig manure composting reduces NH 3 , CO 2 , CH 4 , and N 2 O emissions and improves carbon and nitrogen storage, according to Xie and Tran. 72 Li and Wang 73 and Mei and Li 58 reported that when calcium superphosphate was added to chicken dung NH 3 emissions dropped 31.1% compared to the control. Few studies have examined carbon, nitrogen, and humic material changes during organic−inorganic co-composting, despite the necessity of using fertilizers to prevent nitrogen loss.…”

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.

Hydrogen is believed to be the most potential energy‐resources in the coming time due to its high energy density and zero greenhouse gas footprint. Among all types of hydrogen production processes, bio‐based hydrogen (biohydrogen) generation processes are found to be relatively cleaner than the other processes. In this review article current biohydrogen generation processes are critically reviewed to understand the critical factors associated with the hydrogen generation along with the challenges to be eliminated. In this review the factor like types of substrates, their pretreatment, bioreactor design, and other parametric influences on the overall biohydrogen production is discussed. Also, impact of different catalyst in hydrogen production has been discussed in this topic. The review indicated that most of the current hydrogen‐research are focused on the development of processes with high yield. However, one of the major drawbacks of biohydrogen process is purification of H2 from the gaseous mixture produced by microbial strains. To establish the biohydrogen production processes as promising as it considered to be there needs to have a robust purification system. Also, this review highlights that more rigorous research on the biohydrogen storage and its hazard analysis is necessary to meet the future expectation of hydrogen use in mass‐scale.
