Aurubis - Environmental Protection

Environmental Protection

Environmental and climate protection are among the key targets of Aurubis’ corporate strategy and are outlined in the company guidelines. State-of-the-art plant technologies which set international benchmarks are used in environmental protection. The expansion of recycling activities in the Group helps to close material cycles in an environmentally friendly way and is thus an important contribution to sustainable development. Beyond compliance with legal requirements, voluntary commitments like the chemical industry’s “Responsible Care” initiative are important instruments for continuously improving performance in environmental and health protection at Aurubis. A uniform environmental standard was created and implemented for the Aurubis Group. The environmental management system at all of the main sites in the Aurubis Group are ISO 14001 certified. The Hamburg and Lünen sites as well as Schwermetall Halbzeugwerk are EMAS certified.

A total of € 359 million has been invested in environmental protection measures at the Hamburg site in the past 30 years. Five agreements on improving environmental protection and increasing energy efficiency have been concluded with the Hamburg State Authority of Urban Development and Environment and successfully implemented. In February 2011 a sixth emission reduction agreement was concluded between Aurubis and the city of Hamburg. This sixth agreement comprises environmental protection measures with a capital expenditure totalling about € 20 million and is in effect until 2016.

Aurubis, formerly Norddeutsche Affinerie, is considered to be the biggest heavy metal emitter in northern Germany. In the early 1980s, arsenic and cadmium in particular were shown to be present in the wastewater discharge and in the stacks’ exhaust air. There was an arsenic scandal in Hamburg in 1985 when it was discovered that heavy metals had accumulated in the soil in eastern Hamburg, especially in agricultural areas. This became a scandal because the Hamburg authorities tried to conceal it. The environmental protection group Physik-Geowissenschaften took water and soil samples showing that arsenic, cadmium, copper, zinc and other heavy metals had accumulated in the harbour mud in front of the plant and was still entering the river Elbe in 2005 through cracks in the embankment.
