11. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions
Abstract : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. READ MORE

12. Volumetric combustion of torrefied biomass for large percentage biomass co-firing up to 100% fuel switch
Abstract : The co-firing of biomass and coal plays an important role in increasing the biomass power capacity and reducing greenhouse gas (GHG) emissions. The challenges of the large percentage biomass co-firing (over 20% on energy basis) in existing pulverized coal boilers are keeping the same steam parameters and having a high boiler efficiency and a stable operating.

13. Technical Alternatives and Energy in LCA
Abstract : This licentiate thesis is based on two papers, a comparative LCA case study paper and a paper on energy issues in LCA. A case study was done in order to investigate which of two compared technologies for chemical recovery in the pulp industry (recovery boiler, RB, or black liquor gasification, BLG) is environmentally favourable.

14. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance
Abstract : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. READ MORE
