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:
The EU has committed itself to climate neutrality by 2050, and Austria has set itself this target by 2040 in order to counteract the temperature increase of two degrees Celsius. The reduction of CO2 emissions requires specific approaches and measures from companies. AMAG's declared objective is to reduce specific CO2 emissions and the impact of its business activities on the environment, and thereby contribute to the achievement of national and European decarbonisation targets. AMAG's customers are sustainably supported by the use of alloys with the lowest possible CO2 footprint, a high level of aluminium recycling expertise and a high scrap utilisation level.
In order to categorise the CO2 footprint, the emissions are assigned to three so-called "scopes". AMAG is intensively engaged in reducing such emissions, and is implementing the following measures to this end:
The expansion of recycling competences will continue to shape AMAG's successful course in the future, and will become even more important for the company and its stakeholders in relation to the achievement of climate targets.
In the 2020 reporting year, direct greenhouse gas emissions (Scope 1) amounted to 92,100 tonnes (2019: 104,400 tonnes). No Scope 2 emissions have been generated since the 2018 reporting year thanks to the purchase of electricity from hydroelectric power and other renewable sources.
Specific CO2 emissions (Scope 1 + 2) in relation to production volume (tonnes of CO2/t) grew to 0.168 CO2/t in 2020 (2019: 0.163 tonnes of CO2/t). As with specific energy consumption, this increase is primarily due to reduced plant utilisation and required standby operations due to the COVID-19 pandemic.
For reasons of materiality, only upstream emissions from the purchase of primary aluminium, rolling slabs and metal alloys are included in the calculation of Scope 3 emissions. The factor of 8.6 tonnes CO2eq/t of aluminium used in Europe, as used in the European Aluminium's "Environmental Profile Report", was applied for the calculation.
This covers direct processes and auxiliary processes, thermal energy, electricity and transport. In the 2020 reporting year, Scope 3 emissions amounted to 1,072,000 tonnes of CO2eq (2019: 1,200,000 tonnes of CO2eq).
The water supply at the Ranshofen site is ensured by two service water wells and one drinking water well. AMAG is located on a groundwater body - a stream of water that drains into the Inn River at a rate of approximately 20-40 l/sec and 100 m flow below the plant premises.
The permitted use of industrial water is based on a withdrawal quantity determined by the authority for AMAG. Groundwater withdrawal is accompanied by extensive monitoring, including groundwater level measurements. The groundwater can be utilised directly in AMAG without chemical treatment and without transportation over long distances.
A large proportion of the water extracted is utilised for cooling as part of casting, rolling and heat treatment processes and is thereby only thermally loaded - specifically, this means that a large part of the water that is utilised is only heated, and neither consumed nor contaminated. A very small proportion of the water used is chemically contaminated. This operational effluent is treated in effluent treatment plants and the discharge is continuously monitored by measuring essential parameters via probes. If the measured value is exceeded due to impurities, the water is automatically directed into a separate basin, from where it is disposed of. In addition to ongoing measurement via probes, effluent samples are examined for a large number of parameters as part of certified monitoring by internal and external laboratories. Rainwater is largely drained at the AMAG site.
The total water withdrawal for AMAG in 2020 stood at approximately 3,277,000 m3 (2019: 3,656,000 m3). For the purpose of multi-year comparison, the total water withdrawn in 2007 was added to the bar chart below.
For many years, measures have been implemented as part of sustainable rainwater management.
To this end, numerous seepage reservoirs and seepage troughs for rainwater have been created on the plant site.
The total area of the realised or planned drainage possibilities extends to around 4 hectares. Around 128 hectares of roof and other areas are drained via these seepage areas.
The construction of rainwater seepage reservoirs reduces the volume of rainwater that was previously discharged into the River Inn via a collection channel. As a consequence, a large volume of rainwater from various roof and open spaces on the factory premises is cleaned in a controlled manner and drains away on site. The rainwater drainage is very similar to the natural water cycle: by passing through the seepage reservoirs and troughs, the water is cleaned by a specially installed soil filter. The rainwater treated in this way is fed directly into the body of water on the plant site.
In the manufacture of products, as well as in the performance of production processes and other activities, attention is paid to environmentally sound waste management. A particular focus is placed on disposal of hazardous waste (such as used oil, emulsions, workshop waste and filter dust) in compliance with statutory requirements. Waste law managing directors have been appointed for the collection of hazardous waste, and individuals have been appointed with responsibility for non-hazardous waste. Waste officers are responsible for monitoring compliance with waste legislation, and are required to report to management in this capacity. Waste is recorded entirely according to waste type and volume for the purpose of traceability in accordance with the Waste Documentation Ordinance, and is handed over to licensed companies for disposal and treatment within the framework of the legal provisions.
Specific waste volumes in relation to production volume amounted to 16.6 kg/t in 2020 (2019: 16.3 kg/t). In the 2020 reporting year, waste quantities were recalculated by recording waste from construction activities separately, and no longer under production-specific waste quantities (retrospectively also for the 2019 and 2018 reporting years). A new, quantitative target definition was implemented for the production-specific waste volumes.
AMAG currently owns around 300 hectares of land. The industrially built-up area amounts to around 100 hectares. A total of 178 hectares form part of the company’s own forestry operation, which in turn forms part of the Lachforst forest complex and is managed under the supervision of a forest warden.
This entails special requirements – as does the proximity to the nature reserves "Unterer Inn" and "Buchenwald" only a few kilometres away, the fauna-flora-habitat area (FFH area) "Auwälder am unteren Inn" and the "Salzachmündung" bird sanctuary in Bavaria, which are subject to stringent nature conservation guidelines.
By maintaining green spaces on the company premises, a contribution is made to the preservation of biodiversity. AMAG’s forestry operations are not regarded as commercial forests, where the focus is on economic returns. Rather, the aim is to achieve sustainable management that continuously promotes the forest’s ecological value. Open spaces are designed according to their nature conservationand open space design potential.
The preservation of green spaces thereby forms one of the basic requirements of biodiversity-promoting and climate-adapted green space management. Work is underway at present on a green space maintenance concept which, in addition to economic aspects, includes an optimised contribution to the promotion of biological diversity.
Since the 2017 reporting year, we have published a summarized non-financial statement in our management report, thereby fulfilling our reporting obligation in accordance with the Sustainability and Diversity Improvement Act (NaDiVeG). It summarizes the essential information for AMAG on the five required aspects of environmental issues, employee issues, social issues, respect for human rights, anti-corruption and bribery.
