“…This result shows that it is 15% cheaper to produce AC from HMPW through microwave activation compared to conventional activation, which again demonstrates that microwave activation saves money compared to conventional activation due to the lower energy input during activation. However, the cost reported in this study is higher (2fold) than £2.25 (Chauhan et al, 2023) for the laboratory-scale production of ACs from crop residues. This is related to the higher cost of electricity in the UK than in India (0.27 vs. 0.0043 kWh), although the cost of production is expected to reduce when production is carried out on a commercial scale.…”

“…The remnants of crops, primarily rice, wheat, and sugarcane, contribute signi cantly to the emission of harmful pollutants in India, posing serious health risks to the exposed population. Transforming these crop residues into value-added products for diverse applications could serve as a strategy to address biomass resource waste and reduce on-site crop burning [11]. Using rice straw in biofuel production can help reduce local air quality impacts by preventing burning and lowering greenhouse gas emissions [12].…”

The surplus biomass residue generated from biomass harvesting has enough potential for generating bioenergy and is a promising energy source for future use. Biomass possesses a high moisture content and low calorific value and therefore needs improvement to convert it into solid biofuel. In the present study, torrefaction of lignocellulosic biomass (rice straw) was carried out to enhance its physicochemical characteristics for producing high-grade biofuels and chemicals. For three sets of temperatures (200, 250, and 300°C) and residence times (30 minutes, 45 minutes, and 60 minutes), experiments were conducted in a batch reactor at a heating rate of 10°C.min− 1 in an inert environment. The torrefied products obtained were analyzed using various analytical techniques, such as proximate and ultimate analysis, calorific value measurement, and FTIR analysis. The results revealed that torrefaction at a mild temperature of 200°C and 30 minutes of residence time resulted in a maximum mass yield of 87% and an energy yield of 97%, which subsequently decreased at higher temperatures. The calorific value increased with increasing torrefaction temperature, with a maximum value of 19.50 MJ.kg− 1 occurring at 300°C and 60 minutes of residence time. Since H2O, CO, and CO2 are released upon torrefaction, a significant decrease in the number of hydroxyl groups was observed in the FTIR spectra. Despite the high calorific value at 300°C, 250°C and 30 minutes of residence time are the optimum torrefaction conditions for rice straw due to the significant mass and energy yield and the significant presence of amorphous carbon, as confirmed by Raman spectroscopy. This study will improve the physicochemical properties of rice straw for the production of high-value fuels, chemicals, and other high-strength materials.
