The invention proposes a method of the type comprising at least the following successive steps consisting in: A) preparing a paste (must) comprising the starchy plant starting material (MPV) capable of being fermented; B) bringing about the fermentation of said paste with a view to obtaining a fermented mixture (MF); D) distilling said fermented mixture (MF), at least in part, so as to obtain bioethanol and light vinasse (VL); E1) producing at least a first fuel for the coproduction of energy, in particular thermal energy, using at least a part of the light vinasse. The method comprises a step C1) of separating, by filtration and pressing, the liquid phase (PL) and the solid phase (PS) from the fermented mixture involved before the distillation.
L'invention propose un procédé, du type comportant au moins les étapes suivantes successives consistant à : A) préparer une pâte (Moût) comportant la matière première végétale amylacée (MPV) apte à être fermentée; B ) provoquer la fermentation de ladite pâte en vue d'obtenir un mélange fermenté (MF); D ) distiller au moins en partie ledit mélange fermenté (MF) pour obtenir du bioéthanol et de la vinasse légère (VL); E1 ) produire au moins un premier combustible pour la coproduction d ' énergie, notamment thermique, en utilisant au moins une partie de la vinasse légère. Le procédé comporte une étape C1) de séparation par filtration et pressage de la phase liquide (PL) et de la phase solide (PS) du mélange fermenté intervenant avant la distillation.
