Peter Axegård's presentation discusses the opportunities for a kraft pulp mill to become a biorefinery by extracting additional high-value chemicals and materials from the raw biomass. A kraft pulp mill produces mainly cellulose fibers but also generates lignin and hemicellulose that can be further processed. Lignin applications mentioned include carbon fibers, activated carbon, and binders. Hemicellulose sources like birch wood's xylan could be used to create new materials like co-polymers or extracted into chemicals like lactic acid. The presentation envisions a biorefinery model where the kraft pulp mill more fully utilizes components like lignin and hemicellulose to produce an array of bi
