To realize a biobased economy the production of energy carriers, biofuels, chemicals, materials and food ingredients need to come from biomass derived raw materials. Biorefineries, i.e. process concepts where biomass conversion processes are tightly integrated to provide the production of a palette of products. Biorefineries aims to be material and energy efficient. The majority of the research performed in the group relates to biorefineries in different aspects.
Researchers involved in the biorefineries encompass the whole industrial biotechnology group.
We are active in the Area of Advances Energy and Life Science Engineering. The funding from the Area of Advance Energy has been instrumental in building up the group and its infrastructure.
BioBUF - Upgrading of renewable domestic raw materials to value-added bulk and fine chemicals for a bio-based economy: technology development, systems integration and environmental impact assessment.
The aim of this collaborative project is to assess the potential of co-production of bulk and fine chemicals in a biorefinery concept where sub-processes are highly integrated in order to increase efficiency and minimise the losses. Life cycle assessment, process integration analysis, environmental and economic analysis are part of the core project, in order to predict the impact and the economic performance of the proposed biorefinery.
The acronym BioBuF stays for Biorefinery for Bulk and Fine chemicals. The aim of the BioBuF project is to assess the feasibility and potentials of a so-called biorefinery based on the use of renewable Swedish resources, such as microalgae and forestry residues. Adipic acid from biomass sugar streams and terephthalic acid from lignin are the two bulk chemicals of the envisioned biorefinery; whereas fine chemicals, such as pigments and anti-oxidants, will be derived from micro-algae.
The SEAFARM project aims at developing a sustainable system for the cultivation and use of seaweeds, proposing a renewable resource for a future biobased Swedish society. SEAFARM is a cross-disciplinary project including marine biologists, microbiologists, chemists, food scientists, engineers and economists from 5 Swedish universities and 13 collaborating partners from industry and authorities from three coastal regions in Sweden.
The realization of sustainable bioeconomy solutions depends on the efficient processing of biomass. High gravity technology is one important aspect to realize such processes. The aims of this work were to expand the knowledge-base on lignocellulosic bioconversion processes at high solids, to advance the current technologies for production of 2nd generation liquid biofuels, to evaluate environmental impacts of the proposed process by using Life Cycle Assessment (LCA) and to finally develop and present an economically and feasible process towards high gravity, i.e. operating at the highest possible raw material concentrations. The results and opinons preseted here is the result of the Nordic collaborative study within the framework of the “HG-Biofuels” project. Separate processes with Bioethanol or Biobutanol as target products were studied using the Nordic interesting raw materials wheat straw and spruce. During the project, the main scientific, economic and technical challenges of such a process were identified. Integrated solutions to these challenges were proposed and tested experimentally, using as model substrates, wheat straw and spruce wood at a DM content of 30% w/w. The LCA performed revealed the environmental impact of each of the process steps, underlying the importance of the enzyme dose used for the hydrolysis of the plant biomass, as well as the importance of the fermentation yield.
In the HG Biofuels project, Chalmers University of Technology, University of Copenhagen, Statoil, SEKAB and Inbicon collaborated on developing high-gravity processes for production of ethanol and butanol. The project were funded by the Nordic Energy Research under the scheme of Top-level research Intiative
