AMAG endeavours to exploit aluminium products’ energy-saving potential through a high level of recycling and low energy consumption during production. The casthouses and rolling mills are the main energy consumers at the Ranshofen production site.
Natural gas is utilised in the casthouses to melt and temper aluminium. In the rolling mill, most of the electricity consumed is harnessed to drive the mill stands, and electricity and natural gas utilised in the heat treatment of aluminium strips and plates.
The total energy consumed at the Ranshofen site amounted to approximately 653,200 MWh in 2020 (2019: 745,200 MWh). This is calculated as the consumption of fuel from non-renewable sources (natural gas, diesel, heating oil and propane) and electrical energy.
The lower consumption in the 2020 reporting year arises from the lower production volume compared to 2019.
With regard to energy sources in the electricity mix, AMAG relies on the utilisation of renewable energy sources in order to act in a manner compatible with climate protection. In 2020, for example, AMAG purchased a total of 76 % from hydro power. The share of wind energy and electricity from solid biomass and photovoltaics amounted to 24 %. As a consequence, no indirect CO2 emissions are generated from electricity production.
The following principles are adhered to in this context:
- Efficient energy utilisation through the use of suitable technologies and process optimisation
- Transparent calculation and evaluation of greenhouse gas emissions in compliance with all international and national requirements
- Securing cost-efficient energy supplies through active energy management
- Systematic and regular monitoring of legal requirements and in-house processes
