A method wherein lignocellulosic biomass materials are converted into combustible fuel products. In particular, the method is a continuous process, involving wet oxidation or steam explosion, for fermentatively converting such biomass materials into ethanol using a process design that permits all or part of the process water from the ethanol fermentation process to be recycled to reduce the consumption of process water. The effluent from the ethanol fermentation step may be subjected to an anaerobic fermentation step generating methane and a water effluent in which the amount of potentially inhibitory substances is at a sub-inhibitory level, which in turn permits all or part of the effluent water from the anaerobic fermentation step to be recycled into the process.

L'invention concerne un procédé de transformation de biomasses cellulosiques en produits combustibles. Plus particulièrement, ce procédé est un procédé en continu, comprenant une étape d'oxydation en milieu liquide ou de vapocraquage, destiné à transformer ces biomasses en éthanol par fermentation à l'aide d'une conception de procédé permettant de recycler une partie ou la totalité de l'eau de traitement du procédé de fermentation d'éthanol afin de réduire la consommation d'eau de traitement. L'effluent provenant de l'étape de fermentation d'éthanol peut être soumis à une étape de fermentation anaérobique générant du méthane et un effluent d'eau renfermant une concentration sous-inhibitrice de substances potentiellement inhibitrices, permettant ainsi de recycler une partie ou la totalité de l'eau d'effluent provenant de l'étape de fermentation anaérobique du procédé.
