Emissions and climate impact – own operations

Reducing climate impacts

In line with the company’s climate strategy, Gränges works to reduce energy intensity and promote the use of renewable energy. Emissions to air of greenhouse gases, nitrogen oxides, sulphur dioxide and particulate matter mainly come from the company’s furnaces where aluminium is re-melted either via combustion using fossil fuels or via induction using electricity. The company also emits oil to air and water as a result of the cold rolling operations where oil is used to cool down the mill and lubricate the interface between the rolls and the material.

Gränges strives to take a holistic approach in reducing the climate impact along the aluminium value chain. This for example implies that the company may need to accept slight increases in energy consumption as a result of using more recycled aluminium in the re-melting facilities compared to using primary ingots. The reduction in carbon emissions from sourced metal inputs more than offsets the increase in operational emissions.
