AI helps recycling startups profit from 20% aluminum price surge
▼ Summary
– The conflict with Iran has driven aluminum prices to multi-decade highs, as about 10% of global aluminum is produced in the Gulf region.
– The U.S. relies heavily on imported aluminum, with much domestic production coming from recycled metal, making the material a critical mineral.
– Recycling startups like Amp and Sortera use AI and advanced sensors to sort aluminum from waste streams with over 90% accuracy.
– Sortera opened a new facility in Tennessee that doubles its processing capacity to 240 million pounds, with aluminum making up 90-100% of that.
– Only about 20% of aluminum is recovered in the U.S., and startups aim to capture material from garbage that bypasses recycling systems.
Rising gas prices have dominated headlines since the Trump administration escalated its conflict with Iran in late February, but that’s far from the only commodity feeling the pressure. Because roughly 10% of the world’s aluminum is produced in the Gulf region, prices for the metal have surged to levels not seen in decades, creating a lucrative opportunity for a new wave of recycling startups.
Even before the Iran conflict, the U. S. government had already classified aluminum as a critical mineral. The country relies heavily on imports to meet demand, and much of the domestic supply comes from recycled material. For startups focused on recovering aluminum, the current price spike is a major tailwind.
“Aluminum might be 1% of the garbage stream, but it often trades for over $1,000 per ton,” Matanya Horowitz, CTO of waste sorting startup Amp, told TechCrunch. “It actually ends up being one of the most significant individual commodities.”
Aluminum is among the most recycled materials in the United States, yet the EPA reports that only about 20% is actually recovered. Waste sorting startups have been betting that AI-powered sorting can dramatically improve those figures.
Sortera, a metals recycling startup, recently opened its second facility in Tennessee, the company exclusively told TechCrunch. The new plant doubles its processing capacity to 240 million pounds, with 90% to 100% of that volume being aluminum. That represents a meaningful share of the 4.3 million metric tons the U. S. consumed last year.
The Indiana-based company specializes in sorting aluminum scrap. It relies on a suite of sensors , including lasers, cameras, and X-ray fluorescence , to feed AI algorithms that classify each potato chip-sized piece of scrap by its specific grade. By separating grades with higher precision, Sortera can command a better price per pound.
Amp takes a different approach, deploying its AI-driven sorting system across both recycling and general waste streams.
Its sensors, which include visible light and infrared cameras, identify everything from wrappers to foil and distinguish plastics from aluminum. As materials flow along conveyor belts, robotic arms and air puffers pluck or blow them into separate bins. Amp says its system achieves over 90% accuracy in recovering specific materials, including aluminum.
“Half of the aluminum in a metro area , in places with successful recycling programs , are just in the garbage, not even touching the recycling system,” Horowitz said. For the metals industry, facilities like those being built by Sortera and Amp could help shore up domestic supplies of a critical mineral that flows through nearly every sector of the economy.
“These types of projects are some of the biggest sources of domestically produced aluminum that are coming online in a given year,” he added.
