High substrate concentrations, the path towards viable biofuels production from lignocellulosic material

​Why is the production of biofuels from agricultural and other residues not yet a global commercial reality? One major reason is that the production cost is still high. High gravity bioprocessing is a promising technology aiming at making lignocellulosic biofuel cost competitive with minimal environmental impact.

Operating at high gravity means to run the processes at very high substrate concentrations. Unfortunately, the increase in initial concentration of the raw material is not without challenges for the whole process. In the "HG Biofuels" project we investigate the production of bioethanol and biobutanol at high gravity conditions and we focus on possible ways to overcome these challenges in order to make this technology robust enough to process both agricultural and forst derived feedstocks giving high product yields.

​The project is sponsored by the Nordic Energy Research
​The project is a collaboration between Chalmers University of Technology, Copenhagen University, SEKAB E-technology, Inbicon and Statoil, coordinated by Chalmers University.
