16. Improving Wood Fuel Pellets for Household Use : Perspectives on Quality, Efficiency and Environment
Sammanfattning : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. LÄS MER
17. On the determination and application of local filtration properties
Sammanfattning : Filtration is a mechanical unit-operation used for the separation of liquid and solid. In this work, the three sub-operations cake build-up, expression and washing have been studied. One difficulty often encountered in the design of filtration equipment is that the materials being filtered form more or less compressible filter cakes. LÄS MER
18. Energy and Resource Efficiency in Convective Drying Systems in the Process Industry
Sammanfattning : Growing concern about environmental problems has increased the public’s interest in energy usage. The subsidies for biomass, together with the rising energy prices have madebiomass a desirable product on the energy market. LÄS MER
19. Genome editing of oilseed species by CRISPR/Cas9 for trait improvement
Sammanfattning : The demand for vegetable oils for food and other applications is rapidly increasing due to a growing population and an urgent need to replace fossil oils. Furthermore, there are several challenges facing agricultural production, such as a shortage of arable land, climate change, and water pollution due to nutrient leaching from extensive use of fertilizers and tillage.

20. Membrane Filtration of Lignocellulosic Materials: In situ Monitoring of Membrane Fouling Using Fluid Dynamic Gauging
Sammanfattning : The transition of process industries from utilizing fossil-based resources to bio-based ones necessitates energy-efficient and selective operations. One practical operation that can be employed for processing streams containing lignocellulosic biomass, such as forest and agricultural residues, is membrane separation. LÄS MER
