AMAG is a global player and supplier of primary aluminium and semi-finished aluminium products. It’s "Energy Efficiency Flagship Project" received the "Energiestar" award in the category "Large Scale Energy Innovation". As part of the aluminium casting process, the aluminium ingots are cooled. In the project planned by Siemens, the heat is recovered and temporarily stored in a 28 m high buffer tank. The energy is used to heat the buildings and halls with the support of two heat pumps. This project enables a 35 % reduction of the natural gas consumption and heat savings of 17,000,000 kWh.
