| Abstract | The production of wood fibres, bio-based polymers and engineered wood products within integrated industrial production networks can be organized by industrial decision makers in future production planning with a varying degree in the integration of cross company supply and conversion chains. For instance, the supply with wood fibres in future composite and wood panel production lines can rely on individual or cooperative operation of refinery plants. Also, the feedstock of lignocellulosic biorefineries can primarily be mobilized from raw wood resources or can be sourced from saw mill by-products and/or secondary wood resources. Finally, a major option for coupled use and integration of value added chains between biorefineries and wood manufacturing industries is the production of intermediary and auxiliary materials such as bio-based resins and adhesives for glue-laminated and cross-laminated timber products. Considering these scenarios of varying intensity in coupled use and cascade use of wood resources a baseline scenario was developed and assessed in this study, which serves as a basis for further LCA studies on extended scenarios. If these horizontal and vertical integration options really contribute to favourable reduction of environmental impacts along the bio-based value chains in bioeconomy regions, thereby remains a major question for further in-depth assessments. A life cycle-based approach has been used to model and evaluate the technological processes that take part in wood-based bio-polymer and wood processing supply chains. This work analyses the negative environmental impacts of a future wood-based bioeconomy network and compares its impacts with those of a traditional fossil-based production system. Results show that for the future bioeconomy system for seven out of 11 impact categories a relative advantage between 25 % to 130% of the initial impacts of fossil-based counterparts is attainable. As expected the global warming potential and the abiotic depletion potentials are building the top group with 130 % and 70 % respectively. The inventory analysis shows that the integration of regional and cross company supply chains and the minimization of fossil-based additives and auxiliaries and utility service installations offer further options for leveraging optimization scenarios. |
