Länsvis tillgång på skogsbiomassa för svensk biodrivmedels- och bioflygbränsleproduktion

This study includes an updated analysis of the regional potential of forest-based residues and by-products in form of logging residues after final felling’s, bark in sawmills and pulp mills, sawdust in sawmills, and lignin from black liquor in pulp mills, as feedstocks for future production of biofuels and biojet fuels. The analysis also include calculations of theoretical transportation distances within different regions depending on which feedstock that is utilized and to what extent the feedstock is practical available. Finally, a discussion is performed regarding potential dynamic effects from a large-scale introduction of forest biomass-based biofuel/biojet fuel production in Sweden with respect to how the feedstocks are utilized today and potential future changes in this utilization, including energy efficiency improvements. The results shows a significant aggregated feedstock potential for biofuel/biojet fuel production and that the transportation distances could be reasonable, especially when a co-location with large-scale forest industries is utilized. A number of counties are shown to be especially attractive for the location of large-scale biofuel/biojet fuel production facilities due to their high density of logging residues in combination with a high existence of large-scale forest industries (sawmills and pulp mills) generating large volumes of by-products, which, in turn, leads to limited transportation distances. Examples of such counties are Västernorrland, Gävleborg, Värmland, Kalmar, and Halland.
