From a statutory point of view, ARRONAX is a « Groupement d’Intérêt Public » (GIP). ARRONAX is thus a public research institute with a private accounting. It is a kind of mixed economy system that allows it both to cooperate as equal with public research partners and to act as a company with respect to industrial customers (Siret: 13000411200012, DUNS: 295659028).
A GIP is a grouping of several public and private members, linked by a written agreement, approved by the State. Members of the ARRONAX GIP are the State and the Region Pays de la Loire, large national organizations of research, higher education and research institutions, hospitals. Members are gathered in an Administration Council which elects its president and vice president.
