1. Process development for combined pentose and hexose fermentation
Sammanfattning : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.

2. Modelling Chemical Weathering in Different Scales
Sammanfattning : Chemical weathering is one of the most important processes supporting life on Earth. Chemical weathering continuously contributes macronutrients and micronutrients to the soil solution. These recycling, essential elements are used as building blocks for all organic living matter.

3. Process development for platform chemical production from agricultural and forestry residues
Sammanfattning : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pretreatment impair the economic feasibility of such biorefineries. LÄS MER
4. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts
Sammanfattning : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. LÄS MER
5. Downstream Processing Using Membrane Technology
Sammanfattning : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. LÄS MER
