Non-wood pulping faces environmental and processing problems due to lack of suitable technology. To overcome the challenges, potassium hydroxide pulping was suggested, which can also be integrated with biorefinery. To make a viable biorefinery, all d

Pulping of rice straw was studied using mild nitric acid in mild conditions. Spent nitric acid was chosen as soil nutrient rather than followed by the liquor recovery. The rice straw was treated with 11.03% nitric acid at 90 °C for 3 h, yielded 53.0
