12. Optimization of Investments for Strategic Process Integration and Pulp Mill Biorefinery Projects under Uncertainty
Abstract : 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. READ MORE

13. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol
Abstract : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. READ MORE

14. Mild Steam Explosion of Wood and Forest Residues in the Perspective of a Materials Biorefinery
Abstract : The main objective of this work was to explore the prospects of using mild steam explosion as a pretreatment step in a forest based material biorefinery. During the steam explosion saturated steam is applied to the biomass at elevated pressure leading to an autohydrolysis of the lignocellulosic tissue, which is followed by a rapid pressure discharge, disintegrating and opening up the structure.

15. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts
Abstract : 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. READ MORE
