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 includes a process for producing a protein product from plants and yeasts. The process comprises the steps of: The present invention also discloses a corresponding protein product from plants and yeasts with a crude protein content of at least 70 wt. % DS.

Protein product from plants and yeasts and production process for same

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.

The invention relates to a method for producing biogas from lignocellulose-containing biomass, preferably from straw, and to a plant for carrying out said method.

Method and plant for producing biogas from lignocellulose-containing biomass

The invention relates to a process for producing biogas from fibrous substrate by anaerobic fermentation. The process is characterised in that

Process for producing biogas from fibrous substrate

The invention relates to a method for obtaining at least one organic target product and biogas. The method is characterised in that a) organic substrate is introduced into an anaerobic fermentation process; b) in this anaerobic fermentation process a hydrolysis, acidification and methanation are performed using a mixed culture of bacteria and archaea without spatial separation; c) partial suppression of the anaerobic fermentation is realised, with the result that a part of the organic substrate is not completely decomposed to biogas or methane; d) at least one target product is enriched as an organic metabolite of at least one microorganism in the fermentation process by deliberate incomplete composition of the organic substrate; e) the biogas formed in the anaerobic fermentation process is recovered for further use; and f) at least one organic target product is obtained from the anaerobic fermentation process for further use.
