Fray International Sustainability Award


WESER METALL - Recylex Group


The smelter in Nordenham on the Weser estuary has been producing lead for more than 100 years. Since the installation of the new vertical bath smelting furnace in the middle of the 1990s, Weser-Metall GmbH has been one of the most modern recycling companies in the lead sector. This is clearly highlighted by the use of approx. 70 % lead secondary raw materials (car batteries, etc.), and only approx. 30 % lead concentrates.
