To answer the needs of the strategy of sustainable development, the industrialists of the Atlantic Area seek, now more than ever, procedures and products offering solid environmental advantages. The SUPERMAT project offers them a new prospect for development, founded on the technology of ‘supercritical fluids’. This method, consisting of bringing fluids to precise conditions of temperature and pressure, thus giving them properties which are in between those of a gas and a liquid, makes it possible to use new production procedures – and therefore to create new products – which are innovative and which respect the environment. The SUPERMAT project contributes to strengthening the performance and the competitiveness of the Atlantic Area in a sector of technological innovation which is still dominated by the United States and Japan.
