Aluminum is omnipresent in our trendy world, however its manufacturing comes with a heavy carbon footprint. With Trump’s tariffs driving up costs, we’re reminded that it shouldn’t be wasted—and Iceland might maintain the important thing to its circularity.
DTE, a Reykjavik-based startup rooted within the tiny island’s world-class aluminum trade, has partnered with American aluminum heavyweight Novelis to assist it dramatically improve its use of recycling content material to 75%.
That’s an formidable purpose, although aluminum is—on paper—infinitely recyclable. “In precept, it’s true, however it’s extra difficult than that,” DTE CTO Kristjan Leosson advised Fortune.
That’s as a result of aluminum is available in many types, from airplane wings to constructing frames. “In case you have used beverage cans and also you soften them, you don’t make used beverage cans out of that alloy,” Leosson mentioned. “It’s important to handle all these streams of various recycled aluminum in such a approach that you just make the very best worth finish product once more.”
The tech behind smarter smelting
That’s the place DTE’s proprietary expertise may also help. With superior sensors offering real-time information, the younger firm offers its purchasers the power to investigate the composition of aluminum as it’s melted down, which makes it simpler to include scraps with out compromising high quality.
This stage of precision is particularly necessary as producers work to fulfill rising demand for high-strength aluminum alloys for use in sectors like aerospace, protection, renewable vitality infrastructure, and semiconductors.
Karl Ágúst Matthíasson, DTE’s co-founder and newly appointed Chief Technique Officer, presents a useful analogy to clarify this problem. Chatting with Fortune, he in contrast aluminum scraps to leftovers: When you style them actively sufficient, you would reuse yesterday’s premium lobster soup as inventory for the premium soup of the day.
Stretching the analogy additional, simply as eating places try to supply components domestically, reusing aluminum scrap means counting on a useful resource that doesn’t must be imported. It’s an argument that carries new urgency within the U.S., as the necessity to safe entry to crucial supplies—particularly these important to sectors like protection—add as much as provide chain pressures.
A geopolitical tailwind
“In a approach, the tariffs are an incentive for the recycling enterprise within the West and in all places to make recycled aluminum, so it not directly promotes demand for our product,” mentioned Jakob Asmundsson, a seasoned Icelandic government who grew to become DTE’s CEO earlier this 12 months.
Simply as eating places try to supply components domestically, reusing aluminum scrap means counting on a useful resource that doesn’t must be imported.
However these tailwinds aren’t only a product of the present second, as evidenced by DTE’s relationship with Novelis previous to the brand new Trump presidency. Other than being DTE’s shopper, the aluminum trade participant took half within the $16 million Collection A2 spherical of financing raised by the startup in 2023.
In a brief documentary produced by CBS Information round that point, Novelis senior vp Derek Prichett, cited high quality as one key advantage of DTE, and security as the opposite. Through the use of DTE’s expertise, Prichett mentioned, Novelis “can maintain operators away from our furnaces, away from liquid metallic and out of hurt’s approach.”
Certainly, the most typical different to DTE’s providing—handbook sampling of molten metals for testing every so often—is each wasteful and extremely hazardous. It’s no shock, then, that these harmful, labor-intensive strategies are anticipated to be steadily changed by automation.

Based on Matthíasson, automation will solely be potential with the type of real-time information that DTE supplies to the aluminum trade. Whereas old style for a very long time, the sector has now woken as much as the truth that it must be extra sustainable—an pressing realization, on condition that it accounts for about 2% of each world electrical energy consumption and CO2 emissions. And that’s precisely the place Iceland is available in.
Iceland’s low-carbon edge
The Icelandic electrical energy grid is totally run on renewable vitality from hydro and geothermal sources. Regardless of ongoing controversy over the environmental impacts, this has attracted aluminum smelters which might be capable of produce metallic with considerably decrease CO2 emissions than they’d elsewhere. However Iceland’s contribution doesn’t cease there.
Similar to DTE, different Icelandic startups have emerged out of the island’s aluminum trade. SnerpaPower, whose cofounder labored for Rio Tinto’s native aluminum smelter, develops good administration programs that assist optimize vitality use in power-intensive industries. In the meantime, Arctus Aluminium is within the pilot part of a course of that may minimize CO2 emissions altogether.
Because the U.S. seems to reshore and decarbonize its aluminum provide chains, these Icelandic innovators might play a job by exporting their experience—not aluminum itself, and doubtlessly sidestep the tariffs introduced in by the White Home.
Whereas Iceland’s aluminum exports go nearly totally to Europe, making U.S. tariffs largely irrelevant, the actual alternative might lie in American gamers like Novelis tapping into Icelandic expertise to hit their circularity targets, slicing each prices and emissions within the course of.
“Enhancing the sustainability of the aluminum trade is a fancy process, and goes to require numerous totally different components to resolve the issue. And we really feel that this expertise is a kind of components that may assist us get the place we have to go,” Prichett mentioned of DTE.
