“The award-winning companies show that resource and energy efficiency are taken very seriously in the nonferrous metal industry,” said Garrelt Duin, Minister for Economics, Energy, Industry and Commerce of the state of North Rhine-Westphalia, at the awards ceremony in Essen. “They provide new knowledge and technology-based answers for climate protection initiatives and are a strong signal from NRW, as one of the leading locations of the nonferrous metals industry.”
“As a medium-sized family enterprise that is closely linked to the region, yet must also compete globally, we are committed to making the aluminum manufacturing process as efficient and sustainable as possible. In recent years, we have made investments in the double-digit million range to optimize our processes, and we will remain committed,” said Dr. Martin Iffert, CEO of TRIMET Aluminium SE.
The liquidus measurement technology enables the energy balance of the melted mass in electrolytic cells to be measured during the production of primary aluminum. Based on these measurements, an algorithm minimizes process variations, thereby optimizing energy consumption. In the Essen aluminum smelter alone, TRIMET was able to reduce the specific energy consumption of 360 electrolytic cells from 14.9 kilowatt hours per kilogram of aluminum produced to 13.9 kilowatt hours, thus achieving annual savings of approximately 160 gigawatt hours.
