16. Structural and functional investigation of underexplored carbohydrate-active enzyme families
Sammanfattning : The known consequences of the current fossil-based economy require a transition towards a bio-based economy. Development of biorefineries in which plant biomass can be utilized as a renewable source of energy and building blocks to produce both commodities and high-value products, is a key step in this transition.

17. Innovation for tackling grand challenges : Cleantech industry dynamics and regional context
Sammanfattning : Grand challenges such as climate change put focus away from innovations and innovation policy as engines of economic growth towards fulfilling societal goals and sighting sustainable development. The literature on the geography of innovation has provided valuable insights on innovation activities of firms and industries and how they are positively influenced by co-location. LÄS MER
18. 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
19. Strategies for Renewable Barriers with Enhanced Performance
Sammanfattning : Forest biomass is expected to play an increasingly important role in tomorrow´s global bio-economy as one of the main renewable sources of materials, chemicals and energy. In the framework of the biorefinery concept, the forestry industry is looking for new processes to utilize several fractions in the biomass (cellulose, hemicelluloses, lignin etc. LÄS MER
20. Technology and systems for stump harvesting with low ground disturbance
Sammanfattning : Tree stumps could make a significant contribution to the transition from a fossil- to a bio-based economy, but current stump harvesting operations have adverse ecological effects. The ground disturbance caused by the up-rooting leads to increased carbon emissions from the soil and increases risks of leaching of heavy metals and nutrients, while removal of stump wood increases nutrient removal and reduces amounts of dead wood in the forest.
