Process design and optimization for maximizing biogas yield (MaxBio)

Project


Project code: 22041618
Contract period: 01.08.2019 - 31.07.2021
Budget: 309,645 Euro
Purpose of research: Experimental development
Keywords: biogas, renewable ressources

Both cereal straw and farmyard manure currently represent the largest untapped resource of biomass that could potentially be used in biogas plants. In addition, large quantities of husks and cereal waste accumulate during harvesting and cleaning cereals, which are regionally available as a cheap alternative substrate. Even materials from measures for landscape preservation are not yet used to a large extent in biogas plants. While manure, especially poultry manure, can cause nitrogen overload in the digester, the challenge with lignocellulosic materials lies rather in the difficult handling and the limited degree of degradation. This is exactly where the project "NH3-Feed" comes in, by solving both challenges with a combined process. The aim is the process development and demonstration of the ammonia disintegration of different lignocellulosic residues in combination with mechanical comminution and pelletizing. The necessary ammonia is extracted from the ammonia removal of manure. This is intended to contribute to the improvement of use of both highly nitrogenous residues (e.g., poultry manure) and highly lignocellulosic residues (e.g., straw, husks and landscaping preservation materials).The research is carried out both in the laboratory of the IKTS and in the technical centre of ATS (large scale).
