Sustainability

Green too as regards raw materials
Here at HAI we act extremely responsibly when purchasing “green primary aluminium” or when procuring sustainably produced billets for making profiles.

Supply contract for Natur-Al™ products 

That’s one of the lowest Co₂ footprints in the world for this metal. The entire Co₂ footprint per tonne of aluminium is four tonnes. That’s less than a quarter of the average for the sector as whole.

For HAI as a recycler and recycling smelter, the CO₂  content of the primary aluminium that is obtained has a massive impact on the overall footprint. This supply agreement is a clear statement that the HAI Group is not cutting any corners when it comes to its sustainability commitments. Thanks to the combination of Natur-Al™ aluminium and our recycled materials we can produce billets and rolling slabs using less than two tonnes of CO₂ₑ per tonne of metal. This underlines our efforts to do our bit to improve the future for everyone.  

Consistent green electricity strategy
By buying 100% CO₂-neutral hydroelectricity HAI is committing itself to the green energy transition in this area too.

Simply converting to green electricity has enabled us to significantly improve our overall CO₂ footprint. In 2020 we managed to save about 3,400 tonnes of CO₂ just at the Soest site, and as much as 17,600 tonnes at Ranshofen. As a way of visualising this, the annual CO₂ saving of 21,000 tonnes of CO₂ is equivalent to the footprint of 3,000 people (in Austria each person produces about 7 tonnes of CO₂ every year).

Since January 2021, both sites in Romania are also supplied with electricity generated from renewable energy sources. The majority of the corporate group has thus completed the energy transition.

In addition, in 2019 a 6,300 m² photovoltaic power plant for generating solar electricity was installed on the roofs of the buildings at the Ranshofen site – one of the largest self-consumption PV systems in Austria. In 2019 the system produced 1.268 MWh of green, solar electric power. This means that the Ranshofen location saves roughly 500 tonnes of CO₂ each year. At the beginning of 2021 the system in Ranshofen was expanded again – by a further 3,000 m². Further projects at other company sites are already set to go.

New e-fuel stations are also an important part of our sustainable strategy: once the production of components for battery trays for the EQC (Mercedes-Benz’s first electric-powered SUV) is running at full speed, the mobility revolution will also become a reality at HAI within the company itself. There are already several e-cars in use within the car pool at HAI, including two Mercedes EQCs. At the company’s site in Ranshofen there are also nine charging stations for company cars and for visitors with electric cars.

Using the best technologies to achieve even greater sustainability
Sustainable energy management is also a top priority at HAI. We believe that it is crucial for a company within the aluminium sector to take a responsible approach to its high energy requirements. That’s why at HAI all the processes and procedures are subject to continuous improvement.

In terms of the use of energy and energy consumption this means:

These measures are reviewed and evaluated as part of regularly carried out energy audits, and any new recommendations that are made as a result are implemented.
