Methods combine the operations of a bioethanol production unit and a biogas unit and comprise: (a) mashing corn meal from a dry milling step with at least 0.1 t of dry matter in the form of whole stillage and at least 0.1 mof outflow from the biogas unit per tonne of corn meal; (b) feeding the mash from (a) to a cooking stage with mash temperatures below the gelatinization temperature of the starch in the corn meal, followed by an ethanol-forming fermentation step and then feeding the fermented mash to a distillation step; and (c) feeding the whole stillage from (b) to the mashing step in (a) and to the biogas unit.

The present invention concerns a method for carrying out the combined operation of a bioethanol production unit and a biogas unit. The method comprises the following steps:

1) A method for obtaining a concentrated protein-rich phase from residues of bioethanol production. 2.1) Previously, the separation of a protein-rich phase from whole stillage from bioethanol production has been achieved either by the addition of chemicals or by process steps that are complex in terms of equipment and/or energy. 2.2) Whole stillage from bioethanol production is fed to a solid-liquid separation, and the liquid phase (thin stillage) resulting from this is partially returned to the mashing process. This recirculation increases the raw protein content in the process. Part of the thin stillage is diluted and fed to a simple separation process without the addition of chemicals and temperature treatment, with a protein-rich phase being obtained. 2.3) A protein-rich phase is obtained from residues of bioethanol production.
