“…Composting is an aerobic, thermophilic, solid-state fermentation process. Microorganisms provide the most important energy for the normal operation of the composting system (Pan et al 2021a). Inoculation of compost with exogenous microorganisms can effectively accelerate the maturation process of compost (Alfonzo et al 2021) and promote humus formation (Zhang et al 2021).…”

With the recent revolution in the green economy, agricultural solid waste resource utilization has become an important project. A small-scale laboratory orthogonal experiment was set up to investigate the effects of C/N ratio, initial moisture content and ll ratio (v cassava residue : v gravel ) on the maturity of cassava residue compost by adding Bacillus subtilis and Azotobacter chroococcum. The highest temperature in the thermophilic phase of the low C/N ratio treatment is signi cantly lower than the medium and high C/N ratios. The C/N ratio and moisture content have a signi cant impact on the results of cassava residue composting, while the lling ratio only has a signi cant impact on the pH value and phosphorus content. Based on comprehensive analysis, the recommended process parameters for pure cassava residue composting are a C/N ratio of 25, an initial moisture content of 60%, and a lling ratio of 5. Under these conditions, the high-temperature conditions can be reached and maintained quickly, the organic matter has been degraded by 36.1%, the pH value has dropped to 7.36, the E4/E6 ratio is 1.61, the conductivity value has dropped to 2.52 mS/cm, and the nal germination index increased to 88%. The thermogravimetry, scanning electron microscope, and energy spectrum analysis also showed that the cassava residue was effectively biodegraded. Cassava residue composting with this process parameter has great reference signi cance for the actual production and application of agriculture.

“…1 Currently, about 300 million tons of corn stover, known as one of the major agricultural residues, are produced in China. 2,3 In previous practices, corn stover was openly burned, resulting in severe atmospheric pollution and the loss of valuable resources. 4 To solve this problem, the Chinese government has made great efforts to forbid open burning and guided a multiple utilization strategy for corn stover.…”

“…Lignin, the most abundant aromatic biopolymer, is produced mainly as a by-product of the pulp and paper industry [3,4]. Black liquor is a complex mixture of depolymerized lignin, polysaccharides, extractives, and pulping chemicals [5,6]. Lignin is the main component of the black liquor and makes up 30-45% of the total solids present in the black liquor [7].…”

Black liquor is the by-product of the pulping process where the lignin, hemicellulose, and extractive materials are separated from wood to produce paper pulp. As one of the primary lignin sources, black liquor is considered an important energy source from biomass to produce biofuels and value-added chemicals. However, soda alkaline lignin has limited industrial applications due to its insolubility in water and lack of reactivity. Therefore, chemical modification is essential to enhance its industrial applications. In this study, alkali lignin from bagasse was modified through sulfonation, sulfomethylation, and amination processes using different reaction conditions. The structural analysis of obtained products was investigated by FTIR and 1 H-NMR. The molecular weight distribution and thermal stability of the watersoluble products were analyzed using gel permeation chromatography (GPC) and thermogravimetric analysis (TGA), respectively. The elemental analysis was used to measure the elements (CHNSO) of the obtained water-soluble derivatives. The chemical structure analysis of the samples with FTIR and 1 HNMR confirmed the modification processes. The results indicate that modification led to increased water solubility and a decrease in the precipitation pH of lignin samples, due to the introduction of sulfonate and amin functunal groups on lignin. In addition, the molecular weight and thermal stability of modified lignins were increased due to the presence of sulfonate and amine groups compared to unmodified lignin.
