Résumé

bstract Cassava roots Treatment for food or starch, leaves a large amount of solid wastes such as peels and stillages which are indiscriminately discharged into the environment and amassed as waste dumps on sites where cassava (Manihot esculenta) is processed. All types of cassava wastes produced during the process or peeling are decomposed to generate obnoxious gas and unpleasant odor, enhancing the risk of environmental pollution which is dangerous for the living being and water resources. However, cassava peels as lignocellulosic wastes could be used as starting matter to be converted into the value-added bioproducts. This review article highlights and bring to date different conversion processes of cassava peels used to obtain biofuels (bioethanol and biogas) and activated carbon. The peels could be used to prepare animal feed and as substrate for mushrooms culture. Besides, it is possible to convert cassava peels starch into biodegradable bioplastic. Usin
