Abstract The surplus availability of rice straw, its limited usage, and environmental pollution caused by its inefficient burning has fostered research for its valorization to biofuels. This review elucidates the current status of rice straw potential around the globe along with recent advances in revealing the critical factors responsible for its recalcitrance and chemical properties. The role and accumulation of high silica content in rice straw has been elucidated with its impact on enzymatic hydrolysis in a biorefinery environment. The correlation of different pre‐treatment approaches in modifying the physiochemical properties of rice straw and improving the enzymatic accessibility has also been discussed. This study highlights new challenges, resolutions, and opportunities for rice straw based biorefineries. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd
