Aluminum: AI Boosts Recycling Amid Soaring Prices

Aluminum Prices on the Rise

Current geopolitical tensions, particularly the war in Iran, have led to a dramatic increase in aluminum prices, reaching unprecedented levels not seen in decades. This situation is partly explained by the fact that about 10% of the world's aluminum production comes from the Gulf region, which has directly impacted the market.

Aluminum, a Critical Mineral for the United States

Even before the escalation of the conflict in Iran, aluminum had been designated by the U.S. government as an essential mineral. The United States heavily relies on imports to meet its aluminum demand, and a significant portion of domestic production is based on recycling. For startups specializing in recycling, this situation represents a significant business opportunity.

The Importance of Aluminum in Recycling

Matanya Horowitz, Chief Technology Officer of the waste sorting startup Amp, emphasized that while aluminum accounts for only about 1% of the waste stream, its value often exceeds $1,000 per ton. This makes it one of the most valuable materials to recycle.

Aluminum Recycling in the United States

Aluminum is one of the most recycled materials in the United States, but only about 20% of it is actually recovered, according to the Environmental Protection Agency (EPA). Waste sorting startups see artificial intelligence as a solution to improve these recovery rates.

Sortera and the Expansion of Its Capabilities

Sortera, a startup specializing in metal recycling, recently opened a second site in Tennessee, thereby doubling its processing capacity to 240 million pounds. This site primarily processes aluminum, which accounts for between 90% and 100% of its production. This initiative significantly contributes to the 4.3 million metric tons of aluminum used by the United States last year.

Sortera's Advanced Sorting Technology

Based in Indiana, Sortera focuses on sorting aluminum waste using a range of sensors, such as lasers, cameras, and X-ray fluorescence. These technologies power AI algorithms capable of classifying each piece of waste, even as small as a chip, to accurately identify the quality of the aluminum. This precision allows Sortera to maximize its profits per pound of sorted aluminum.

Amp's Innovative Approach

Amp, on the other hand, uses an AI-powered sorting system to process both recycling streams and general waste. This system relies on sensors, including visible and infrared cameras, to identify various materials, from packaging to aluminum foil, and to distinguish plastics from aluminum. Waste moves along conveyor belts where robotic arms and blowers separate materials with over 90% accuracy, according to Amp.

Untapped Potential in Recycling

Horowitz also noted that in metropolitan areas with effective recycling programs, half of the aluminum ends up in the trash without even going through the recycling system. Recycling facilities like those of Sortera and Amp could play a crucial role in increasing the supply of aluminum, a critical mineral for the economy.

Conclusion on the Impact of New Facilities

According to Horowitz, these projects represent some of the largest sources of locally produced aluminum coming online each year, thereby strengthening national supply and reducing dependence on imports.
