The present application relates to a process for manufacturing maleic anhydride that comprises the following steps: a) fermentation of renewable raw materials and optionally purification to produce a mixture comprising at least butanol; b) oxidation of the butanol to maleic anhydride at a temperature generally between 300 and 600 DEG C, using a catalyst based on oxides of vanadium and/or of molybdenum; c) isolation of the maleic anhydride obtained at the end of step b). It also relates to the maleic anhydride obtained from renewable raw materials, to the copolymers and the compositions comprising said maleic anhydride and also to the uses of this maleic anhydride.
