Dusseldorf – Luther advised Aurubis AG on a national flagship energy efficiency project: In the presence of Hamburg's environmental senator Jens Kerstan, the world's leading copper group signed an agreement on 17 February 2017 with enercity Contracting Nord GmbH concerning use of industrial waste to supply eastern Hafencity in Hamburg. The project is one of ten flagship energy-efficient thermal waste usage projects at the German Energy Agency (dena) and provides a meaningful contribution to thermal energy change. The idea behind the project makes sense. Industrial waste heat occurs as a by-product of copper smelting in the Hamburg Aurubis plant which allows the use of energy-efficient heating for eastern Hafencity. This industrial waste heat is virtually free of CO2 and, through its use, future emissions of more than 20,000 tonnes of CO2 can be avoided per year.
Enercity Contracting Nord GmbH, which specialises in decentralised heat supply solutions, is a company of Stadtwerke Hannover AG and takes on the waste heat from the Aurubis heat supply for its customers in eastern Hafencity.
For the city of Hamburg, the Aurubis and enercity project signifies a significant step in implementation of heat change. For the first time, an entire city district is being supplied almost entirely in a climatefriendly manner using industrial waste heat. The project is unique in its magnitude and sets new standards for intelligent heat supply in other cities in Germany as well.
