This new portal set up by CETIAT (Centre Technique des Industries Aérauliques et Thermiques) and the French Energy Agency ADEME (Agence de l’Environnement et de la Maîtrise de l’Énergie) offers complete and detailed guidance on the industrial waste heat recovery, especially in the French context. It provides an overview on this topic and details some issues, including the interest of heat recovery, the associated technologies and methodologies. The heat recovered from the industry may be used in surrounding buildings, using a district heating network.
