6. Process integration studies on Kraft pulp-mill-based biorefineries producing ethanol
Sammanfattning : Large scale, sustainable production of biofuels will require commercialization ofprocesses using lignocellulosic feedstocks. These processes are still notcompetitive with existing pathways, however. The competitiveness oflignocellulosic biofuel production plants could potentially be improved if theywere integrated with already existing facilities. LÄS MER
7. Optimization of Investments for Strategic Process Integration and Pulp Mill Biorefinery Projects under Uncertainty
Sammanfattning : Energy-intensive industrial plants operate in a changing, uncertain environment. Long-term changes are expected in energy prices, political regulations and technology development. Pulp and paper companies, like many other industries, are under strong pressure to respond to these changes. LÄS MER
8. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill
Sammanfattning : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. LÄS MER
9. Anaerobic digestion in the kraft pulp and paper industry : Challenges and possibilities for implementation
Sammanfattning : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

10. Low consistency refining of mechanical pulp : process conditions and energy efficiency
Sammanfattning : The thesis is focussed on low consistency (LC) refining of mechanical pulp. Theresearch included evaluations of energy efficiency, development of pulpproperties, the influence of fibre concentration on LC refining and effects of rotorposition in a two-zoned LC refiner. LÄS MER
