  1. 6. Analysis and Valorization of Bark from Silver Birch, Scots Pine, and Norway Spruce : Compositional analysis of bark from common Swedish trees in forestry, to optimize sustainability procedures and monetary value of bark residue

    University essay from Umeå universitet/Kemiska institutionen

    Author : Isak Lindbäck; [2022]
    Keywords : ;

    Abstract : Silver birch, Scots pine, and Norway spruce are the three most common types of trees in Sweden and make up to 90% of standing volume in Swedish forests (Skogsstyrelsen 2015, 3). With millions of cubic meters of wood being cut down annually, bark and other residues that cannot be used for sawn timber is left over and burnt for energy. READ MORE

  3. 7. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

  5. 9. Foderåtgång och tillväxt hos mjölkraskvigor utfodrade med bioraffinerad presskaka från gräs/klöverensilage

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Alma Hagskär; [2022]
    Keywords : ungdjur; ensilage; bioraffinerad presskaka; konsumtion; tillväxt; hull;

    Abstract : Bioraffinering är en process där ensilage eller grönmassa, med hjälp av en skruvpress, delas upp i en presskaka och en pressjuice. Presskakan kan utfodras till idisslare och pressjuicen kan utfodras till grisar, bioraffinering möjliggör därför utfodring av vall till grisar i större utsträckning och ger på så vis vallen ett bredare användningsområde.

    Abstract : Sverige har som mål att bli helt fossilfri till år 2045. Energymyndigheten har därför tagit fram ett förslag till Vätgasstrategi för att ställa om vätgasproduktionen till att vara helt fossilfri till 2045. Idag används ca 180 000 ton vätgas, vilket motsvarar ett energiinnehåll på ca 6 TWh. READ MORE
