The following Value Chain diagram presents the linkage of a farm model (EFEM) and a techno-economic location optimization model (BIOLOCATE) for evaluating the straw-to-energy and the innovative straw-to-chemical value chains in the German federal state of Baden-Wuerttemberg, taking into account the spatially distributed and price-sensitive nature of straw supply. The general results reveal the basic trade-off between economies of scale of the energy production plants and the biorefineries on the one hand and the feedstock supply costs on the other hand. The results of the farm model highlight the competition for land between traditional agricultural biomass utilization such as food and feed and innovative biomass-to-energy and biomass-to-chemical value chains.
