Providing heat from copper to urban areas

Copper producer Aurubis will be using its industrial residual heat to power the Hamburg district of Hafencity East. This is the first time that an entire district will be almost completely supplied from industry (in cooperation with the relevant heat supply company).

Using the heat from Aurubis’s copper smelting will save 20,000t of CO2 emissions per year. As well as saving 4,500t of CO2 in Hafencity East, the heat will be used in the Aurubis plant to replace natural gas currently used for producing steam.

Each of the three lines from Aurubis’s Hamburg sulphuric acid plant can provide 160 million kilowatt hours (kWh) on average annually. Only one line is needed to supply Hafencity East. Using Aurubis’s full potential in the future could supply nearly 500 million kWh of heat and cut around 140,000 tonnes of CO2 each year.
