Summary: The study found that removing the grain sink significantly increased sugar accumulation, biomass, and Brix degrees in sweet sorghum. Therefore, further development of sorghum varieties without a grain sink to maximize sugar yield for biofuel production is justified.

Summary: This study evaluated the effect of hydrothermal pretreatment on the availability of fermentable sugars in sweet sorghum bagasse (SSB) and the energy balance of the process. It was found that increasing the severity of pretreatment significantly increased the release of sugars and energy consumption. The PSSF process resulted in a bioethanol production of 22.17 g/L.

Summary: The study investigated the influence of different treatments on hemicellulose solubilization, xylose and glucose production from sweet sorghum bagasse, stalk, and leaves. Results showed that using 10% NaOH for pretreatment of bagasse and stalks resulted in the most effective hemicellulose solubilization, while biomasses pretreated with 10% H2O2 exhibited high enzymatic hydrolysis yield.

Summary: This paper investigates the effects of sewage sludge on biometric parameters, absorption of mineral elements, and thermal characteristics of sweet sorghum grown on Technosol. The study found that the use of sewage sludge treated with DAMET flocculant resulted in increased fresh biomass yield by 14.5-41% when applied at a maximum rate of 60 t/ha. Sweet sorghum actively absorbs nutrients from the soil, with nitrogen absorption increasing by 12-40% to 80-112% depending on the type and dose of sewage sludge application. Sewage sludge influences the thermal degradation process of sweet sorghum biomass, promoting decomposition at lower temperatures and higher rates.

Summary: In this study, a simple strategy was developed to prepare 2D sheet-like biochar by using the dimethyl sulfoxide/potassium hydroxide (DMSO/KOH) superbase system. The resulting biochar showed high graphitization degrees and could be compounded with cellulose nanofibers to solve the molding problem, which is beneficial for dyeing wastewater treatment.

Summary: Sweet sorghum is a crop grown commercially in Nigeria that has high bio-waste energy in its stalk. This study aimed to optimize the gasification of sweet sorghum stalk residue to maximize the yield of combustible gases. The research found that at the optimum conditions, the hot gas efficiency was 81%.

Summary: Nitrate application significantly promotes cadmium accumulation in sweet sorghum compared to ammonium, leading to higher dry weight and Cd concentrations. The effects of nitrate on Cd accumulation and antioxidant capacity under Cd stress are stronger than those of ammonium, indicating that nitrate is more suitable for Cd phytoextraction in sweet sorghum.

Summary: The study found that pretreatment with hydrogen peroxide can significantly improve the bio-oil yield of sweet sorghum stalk methanolysis and decrease the optimal temperature for maximum yield. Pretreated sweet sorghum stalks have more grooves, higher specific surface area, and enhanced physical and chemical structures, contributing to improved methanolysis and bio-oil properties.

Summary: The study explored the use of sorghum grain extract as a source for bioplastic films. The extract is rich in carbohydrates and proteins, making it an ideal material for bioplastic production. Additives such as carrageenan and sorbitol were used to improve the film's properties. The results showed that the incorporation of sorbitol reduced the tensile strength but increased flexibility, and the bioplastic films had a lower water vapor transmission rate compared to petroleum-based plastics.

Summary: Sweet sorghum is a high-yield crop with strong resistance that could support the development of the forage farming industry in China's salt-affected lands. The effects of nitrogen fertilizers on sweet sorghum cultivation in salt-affected lands are debated. This study analyzed the factors influencing biomass yield and nitrogen productivity of sweet sorghum in both inland and coastal salt-affected lands, finding that the recommended nitrogen application rates differ between the two areas.

Summary: Recycling renewable energy waste, such as nutrient-rich biomass ash, through composting for biofuel crop fertilization has been found to be effective in closing the nutrient loop and reducing greenhouse gas emissions. This study investigated the impact of nutrient-rich compost on energy crop production and carbon input to the soil in two different agroclimatic conditions. The compost treatments resulted in better biomass growth in both sweet sorghum cultivars and had a significant effect on biomass ash and juice yield. The results suggest that compost can improve plant growth, biomass fuel, and carbon storage in the soil, contributing to a more circular biofuel production system.
