  1. 1. Technical Alternatives and Energy in LCA

    Författare :Carina Rehnström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : 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.
