The aim of this work is to optimize the alkaline hydrolysis of rice straw lignocellulose using kanwa, with the goal of producing bioethanol. The alkaline pretreatment was carried out using a saline rock from North Cameroon (kanwa) under the following experimental conditions: temperature between 170 and 200°C, and duration between 20 and 60 minutes. Characterization revealed that the local material contained 91.75 ± 0.48% dry matter, 8.25 ± 0.48% water, 31.22 ± 2.04% cellulose, 9.92 ± 2.46% lignin, and 17.72 ± 0.51% hemicellulose.
