Microeconomic analysis for the establishment of an additional wood waste stream for model LC biorefining processes
The main objective is to perform a cost analysis for the procurement for waste wood based on current and projected gate costs considering different grading qualities and future demand scenarios based on socio-ecological market needs. This includes a processing cost analysis at recycling company levels for different recycled wood waste grades as secondary products comparing state-of-the-art with future demands for LCF for typical well established biorefining processes. An estimation of minimal sales proceeds for secondary wood waste chips to be valorized as LCF in a multiple feedstock biorefining process will be provided. Profitability calculations for an established biorefining process producing bio-ethanol and a model biorefining process with the output of bio-chemicals using LCF from secondary wood waste biomass shall be conducted. The microeconomic analysis in this WP is strongly linked with the matrix established in WP1 regarding multiple feedstock composition in recycled secondary waste wood chips, their qualities and sorting/selection criteria.

Environmental assessments by means of an LCA analysis to evaluate the impact of an additional wood waste stream for model LC biorefining processes
According to the ISO 14040 standard the first phase of an LCA is the definition of the goal and scope. In this step all general decisions for setting up the LCA system are made. An LCA is an iterative process and this allows redefining the goal and scope later in the study based on the interpretation of the results. In the wood waste recycling industry the system boundaries for LCA are of cradle to gate type and therefore the respective material flows within these boundaries shall be defined for representative waste wood recycling businesses in Germany, U.K, Slovenia and Finland. The LCI analysis includes data collection and the compilation of the data. The LCI includes collecting quantitative and qualitative data for every unit process in the system. The data for each unit process can be classified in: energy inputs, raw material inputs, ancillary inputs, other physical inputs, products, co-products, wastes, emissions to air, water and soil, other environmental aspects.
