摘要：Reducing oil dependence with renewable resources“ – this is how the German Federal Government subtitles its strategy to strengthen the bio‐based economy (BMBF 2013). The bioeconomy encompasses all economic sectors that produce, process and trade bio‐based renewable resources. The raw materials are largely provided by agriculture, forestry, fisheries and aquaculture. But in which quantities are they produced? Which quantities are imported and exported? How are the raw materials currently utilised? Are there residual or waste materials that can be used? The purpose of this report is to provide an overview of production, trade and utilisation of products from the agricultural and forestry sectors as well as from aquatic resources and aquaculture. Future potentials as well as the possibilities of using residual and waste materials for energy production are assessed. The results show that the agricultural sector primarily produces food and feed. Notwithstanding, more than ten percent of the agricultural area in Germany is currently dedicated to the production of raw materials for energy and material uses. The potentials for the generation of energy from residual and waste materials are deemed to be small. A large share of products and by‐products from fisheries and aquaculture are consumed as food in Germany. Waste from fish processing can be completely used for the production of fish meal and oil. An increase of catch of the species that are relevant for the German fishery sector seems unlikely. Roughly three fifths of the consumption of raw wood in Germany are attributed to material use, the remaining two fifths to energetic use. The latter sharply increased in recent years, mainly driven by the growing demand of private households. Due to overexploitation, especially of spruce, in the past the potential use of raw wood in German forests is largely exhausted or restricted by environmental protection schemes.
