NOVELTY - Method for providing extruded pulp, involves providing plant material comprising plant cells, and vacuum extruding the plant material to break open the intact plant cells resulting in extruded pulp.    USE - The method is useful for providing extruded pulp, which is useful for producing biofuel(s), preferably ethanol, biogas and/or biodiesel (claimed).    ADVANTAGE - The method produces 19% more of ethanol.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) extruded pulp obtained by performing above-cited method;    (2) use of the extruded pulp or its extracted liquid phase or solid subject matter contained in the extruded pulp in aerobic or anaerobic fermentation for the production of one or more biofuel(s) such as ethanol, biogas and/or biodiesel;    (3) use of vacuum tank or vacuum chamber for preparing extruded pulp;    (4) multi-step method for subsequent production of ethanol and biogas using plant material, involves (a) providing a plant material comprising plant cells as feedstock, (b) subjecting the feedstock to the vacuum extrusion of provide an extruded pulp, (c) subjecting the obtained extruded pulp or its portion to aerobic fermentation in a batch process or as a continuous process in a fermentor to provide a fermented mixture, where the fermented mixture comprises ethanol, (d) separating the solid organic matter contained in the fermented mixture from the liquid phase and isolating the ethanol from the liquid phase using a distiller, and (e) using the solid organic obtained matter in step (d) as a fuel for anaerobic fermentation in a biogas reactor to produce biogas or as a feed additive for livestock, or as a fertilizer, where the distillation and/or the separation of the liquid phase from the residual solid matter and/or the separation of the ethanol from the liquid phase using a distiller is performed using energy produced from a biogas reactor, and the liquid separated from the residual solid matter and/or any aqueous effluents from the process is used as water for irrigation, cooling systems, or any other suitable use, such as in the preparation of new fermentation mixtures; and    (5) method for producing ethanol, involves (a) providing a plant material comprising intact plant cells, (b) vacuum extruding the plant material, and (c) fermenting the extruded pulp to provide a fermented mixture.
