A rising demand leads to a gap of 30°million°m³ of wood in the year 2020. Furthermore, the expansive energy demand meets on an expansive market of wood product industry. The increased consumption of wood in the construction sector, chemical industry and in the wood product industry, additionally the increased demand in the energy area for a low climate impact energy supply are leading to a necessity for an overall strategy for the usage of the resource wood. The German government is willing to increase the energy supply with bioenergy and especially wood! Under the aspect of utilization efficiency the upstream arrangement of one or more material utilization steps should be prioritized to the energetic utilization. Due to this facts, the cascade utilization of wood is discussed as a solution in Germany.
But how can the cascade utilization of wood be realized in a regional context? Are there any regional or supra-regional strategies for the expansion of energetic wood utilization? Is it a fact, that the increase of energy out of the raw material wood has to be taken place only after an utilization as a material? And what does it mean in terms of regional politics and policies?
The analyzed area is the German federal state Saarland. Two wood products manufacturer and some biomass plants have a site this region. With this in mind the project analyses process chains and life cycles of wood utilizations with the special focus of energetic usage of the resource in comparison to alternative utilization ways. The existing situation of the wood market in the region will be evaluated on economical, ecological and social terms. “Free potentials” of wood in the region will be also analyzed concerning the possibilities of “mobilization” and the importance in the whole system. The results are applied and approved in another region of Germany aiming at a general validity and dissemination of the results.
The aim of the project is a new evaluation in terms of coexistence between energetic and material wood utilization. The project will develop a concept for a wood platform which involves wood from different sources and the coexistence of different utilization ways. Additionally a concept for the integration of agro-wood in the existing wood supply will be developed. After establishing the wood platform expansion in the sectors “green chemistry” and fuel production are planned.
IIWH investigated sustained available wood potentials, the current wood-use, prospective wood-demand and economic limiting factors relating to wood potentials in the model-region. Furthermore a socio-economic analysis of the wood and forest cluster containing the wood-based panel and sawmilling industry was carried out. Additionally a concept for the integration of wood from short rotation coppices in the existing wood supply was developed and the establishment of short rotation coppices, considering regional restrictions, were explored.
IFEU investigates the environmental impacts of a strategy for a cascade utilization of wood with the means of life cycle assessment. In this context, the equivalent products made out of other materials as well as the equivalent net energy from fossil energy carriers will be taken into account. Apart from forest wood, also short rotation wood is analysed.
