  1. 11. Effects of forest management on greenhouse gas fluxes in a boreal forest

    Författare :Patrik Vestin; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :Forest management; Greenhouse gas fluxes; Clear-cutting; Thinning; Stump harvesting; Selective cutting; Eddy-covariance; Flux-gradient; Greenhouse gas budgets; CO2; CH4; N2O;

    Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

  3. 12. Analysing performance of bio-refinery systems by integrating black liquor gasification with chemical pulp mills

    Författare :Muhammad Raza Naqvi; Yinyue Yan; Chou Siaw Kiang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-refinery; Biomass; Black liquor gasification; Bio-fuel; Pulp mill; CO2; Conversion efficiency; Integration; Synthesis gas;

    Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass utilization. The pulp and paper industry consumes a large proportion of the biomass worldwide including bark, wood residues, and black liquor. LÄS MER

  4. 13. Possibilities of CO2 emission reduction : process integration analysis and carbon trading schemes

    Författare :Chuan Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Climate change is one of the greatest challenges faced by today's society. With more evidence from scientists, the need to manage greenhouse gas emissions has been increasing in response to international climate change negotiations. LÄS MER

  7. 15. Climate change mitigation through CDM : bioenergy technology and energy efficiency in the steel industry

    Författare :Chuan Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Climate change is one of the most significant challenges to sustainable development facing the international community. Increased attention has been given by industries and governments from both industrialized and developing countries to reduce greenhouse gas (GHG) emissions through the clean development mechanism (CDM), one of the Kyoto Protocol's (KP) flexible mechanisms.
