This foresight study intends to contribute to maintaining and even strengthening the competitiveness of this sector in the future. The approach was to: (1)Identify and map future scientific and technological developments in the chemical sector from a socio-economical perspective, (2) Offer companies in the chemical sector in particular their R&D managers, a window-of-opportunity through which to gain a long-term perspective on the industry and anticipate their future needs in terms of RTD capacity.
