摘要：This working paper analyses the material flows in the German biofuel sector for the year 2007. Several statistics were evaluated to indicate which percentage of raw materials went into biofuel production and further energetic uses versus the sectors food and feed. Further the report mentions which by-products are generated and if possible these are quantified. By the use of trade statistics the quantities of imported raw materials were identified. Trade statistics for biofuels are hard to obtain; therefore only net imports of biofuels (consumption minus national production) were calculated which can lead to discrepancies regarding the actual imported and exported biofuel quantities.
