The careful management of resources is a global economic issue addressed by the technologies promoted by Eren Groupe. Although some of these technologies have already proved their worth internationally, Eren Groupe intends to consolidate its position in the French market, before rolling out to the main industrialised or emerging countries in 2023, alone or in partnership with leading local players. The efficiency of its technical solutions, combined with the economic strength of its industrial service operator model, will enable Eren Groupe to establish itself as the leading international group dedicated to the conservation of natural resources.
