  • Method and plant for producing biogas from lignocellulose-containing biomass
    Patent number: 11352596
    Abstract: 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.
    Type: Grant
    Filed: December 16, 2013
    Date of Patent: June 7, 2022
    Assignee: VERBIO VEREINIGTE BIOENERGIE AG
    Inventors: Oliver Ludtke, Michael Schlimbach, Enrico Fichter, Jens Horn, Georg Pollert, Jan Kuhling
  • Method for material use of organic substrate
    Patent number: 10837033
    Abstract: 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.
