The biomass industry (based essentially on wood energy, or dendroenergy, in IDF) would benefit from better structuring, including the construction of a supplier network and the creation of multimodal platforms. As for waste-to-energy, the region could take industrial ecology initiatives further in such a way that waste from some firms constitutes resources for others, an approach demonstrated in cities such as Kalundborg (Denmark), Guigang (China) and Paju (Korea). As the leading agricultural region in France, which is in turn the leading agricultural producer in the European Union, Paris-IDF already possesses assets in organic farming, not to mention a strong growth potential. Development of this type of farming, which is generally more environmentally friendly than traditional agriculture methods, would serve to strengthen short delivery circuits, biodiversity, product quality, and hence the region’s attractiveness.
