Driving a sustainable Future with from HAI
With , HAI makes it easy for customers to credibly reduce their own carbon footprint.
Emissions up to 80%
Lorenz Kögler, Plant Manager HAI Casting Ranshofen, talks about the high recycling rate at HAI. He gives exciting insights into the use of scrap and know-how in the Ranshofen foundry of the HAI Group.
Lorenz Kögler: „Such a high scrap rate requires an optimal infrastructure. At HAI, sales planning and scrap purchasing are located in one department. This guarantees a sufficient supply of suitable scrap for production. It is very helpful that our plants can process different qualities and that we have the possibility to process certain scrap in-house.”
Lorenz Kögler: „Recycling scrap massively reduces the carbon footprint and also reduces energy use. In addition, scraps are cheaper than primary aluminum. What many people don’t know is that scrap, when handled properly, has a higher metal purity than primary metal. However, the process of reprocessing is very complex and it takes extensive expertise to achieve the highest quality.”
Lorenz Kögler: „Thanks to our ability to use a wide variety of scrap types, we are much more flexible in purchasing. A special furnace technology enables us to also use contaminated scrap. This allows us to act very flexibly when purchasing scrap. The prerequisite for this is storage according to type as well as careful incoming inspection. Since HAI was founded, we have consistently built up and expanded our expertise and infrastructure for this purpose. At HAI, we are continuously working on increasing the scrap quota.”
Lorenz Kögler: „At HAI, very experienced employees inspect the delivered scrap. Here, work has to be done with random samples, which is why a lot of experience is needed to obtain reliable test results. The inspection scope is adapted to quality standards of the suppliers in order to combine efficiency with quality.”
Lorenz Kögler: „First of all, there needs to be grade-specific storage. Then it comes down to the optimal mix of scrap types to achieve the desired customer analysis. This requires a lot of experience and technical know-how. HAI has developed a software together with a plant manufacturer, which focuses on the lowest consumption of primary aluminum. For the high scrap rate and quality at HAI, the cooperation of all departments is aware of the importance of the scrap quota. We approach purchasing, preparation and further processing with the usual HAI dynamism.”
Lorenz Kögler: „There is always room for improvement! We have achieved the 80% with consistency, continuous optimization and innovations. We will continue to work on increasing the scrap rate, because our customers’ expectations and emission targets are also evolving. It’s always a matter of staying tuned and keeping pace!”
The HAI aluminium cycle
“Recycling and the sustainable manufacturing of our products that is associated with it have become key issues for the future. For us it’s important to ensure that scrap aluminium from all our product segments is efficiently recycled so as to increase our recycling rates and consequently make a contribution to climate neutrality and the circular economy.”
