Abstract Biomass is one of the promising alternatives to petroleum‐derived materials and plays a major role in our fight against climate change by providing renewable sources chemicals materials. Owing its chemical structural complexity, transformation biomass into value‐added products requires profound understanding composition at different scales innovative methods such as combining physical processes. In this context, use mechanochemistry valorization currently growing owing potentials an efficient, sustainable, environmentally friendly approach. This review highlights latest advances (i. e., chitin, cellulose, hemicellulose, lignin, starch) functional using mechanochemical‐assisted methods. We focused here on methodology processing, influencing factors, resulting properties with emphasis achieving rather than breaking down biopolymer chains smaller molecules. Opportunities limitations associated were discussed accordingly for future directions.
