Karl Hoffmann, Global Sales Director at STEINERT GmbH, Germany, brings over 30 years of experience in environmental technology. Leading the company’s global Metal Recycling Division since 2018, he spearheads innovation in sensor-based sorting systems that enable recyclers to achieve superior aluminium recovery and quality.
In an interview for “Sustainability & Recycling: Aluminium's Dual Commitment” e-Magazine, Hoffmann delved into the pivotal role of sorting in enhancing aluminium recycling efficiency, product quality and sustainability. He further highlights STEINERT’s advancements in digitalisation, automation and alloy-specific sorting technologies, underscoring their growing importance in achieving global decarbonisation and circular economy goals.
AL Circle: What role does sorting play in ensuring efficient aluminium recycling? Has the industry, in your view, fully recognised its importance and invested adequately in advanced sorting technologies?
Karl Hoffmann: Sorting is the backbone of efficient aluminium recycling. The consistent and comprehensive use of innovative sorting technology, including the sorting of aluminium alloys, enables high yields of high-quality secondary aluminium to be produced.
While the industry increasingly recognises its importance, we still see varying levels of investment in advanced sorting technologies worldwide. At STEINERT, we have been pioneering sensor-based sorting solutions that enable recyclers to unlock the full value of their aluminium streams.
AL Circle: Can efficient sorting directly enhance the output and quality of recycled aluminium? In other words, is it fair to say, “the better the sorting, the better the quality of low-carbon aluminium”?
Karl Hoffmann: Absolutely. The quality of recycled aluminium is directly linked to the efficiency of the sorting process. The cleaner and more precisely sorted the fractions, the higher the output and the lower the need for energy-intensive refining steps. Put simply: the better the sorting, the better the quality of low-carbon aluminium. Our solutions help recyclers consistently deliver secondary aluminium that meets the demanding standards of industries such as automotive and packaging.
AL Circle: With recycling initiatives gaining momentum globally, do you anticipate rising demand for sorting technologies? What sales growth or targets are you aiming for over the next five years?
Karl Hoffmann: In light of global recycling initiatives and decarbonisation targets, demand for advanced sorting technologies is rising sharply. We anticipate strong growth in all key regions as recycling companies seek to expand their capacities and improve quality. Over the next five years, STEINERT intends to further expand its market presence and drive growth in order to respond to both the urgency and the opportunities in aluminium recycling.
