A report from the Center for Strategic Industrial Materials argues that recovering more aluminum from scrap could help address U.S. supply pressures, with far less energy than producing virgin metal. New sorting technologies show promise, but the scale of their impact and the policies needed to expand their use remain uncertain.
A new policy push is urging U.S. officials to improve aluminum recycling, as supply constraints and tariffs put pressure on domestic metal supplies. A report from the Center for Strategic Industrial Materials says better sorting could recover more aluminum now lost in waste, offering a lower-energy source of metal than new production in smelters.
Recycling aluminum uses about 5% of the energy required to produce virgin aluminum in a smelter, according to the report cited by Canary Media. Yet millions of tons of scrap still go to U.S. landfills, while some metal is exported for sorting or processed into lower-value products. The report’s authors say inconsistent recycling policies and difficulties separating valuable material contribute to the loss.
Much of the challenge is technical. Scrap can contain aluminum mixed with copper, brass and titanium, and recyclers may need to distinguish among aluminum alloys made for specific uses. Conventional sorting systems can miss material, particularly when a plant is overloaded or equipment is faulty, Greyparrot co-founder Ambarish Mitra told Canary Media.
Companies are testing tools intended to improve recovery. Sortera Technologies raised $45 million last year to build a second facility, in Lebanon, Tennessee, using technology to separate valuable alloys from mixed scrap. Greyparrot installs AI-equipped cameras at recycling plants to track materials. At a Circular Services facility in Brooklyn, which handles much of New York City’s curbside recycling, Greyparrot found that 89% of aluminum passing through was recyclable, Mitra said. That figure describes material at that particular plant, not a national recovery rate.
Recycling Could Reduce Supply Pressure
Recovering more scrap could add to domestic aluminum supplies without requiring the same energy-intensive production as primary metal. That matters as aluminum demand grows for cans, solar panels, vehicles, power cables and data centers, while proposals for new or reopened U.S. smelters depend on access to large quantities of low-cost electricity.
The Center for Strategic Industrial Materials also frames recycling as a supply-chain security issue. Its director, Benjamin Carlson, said greater use of recycled aluminum could leave more virgin metal available for military and aerospace applications that require high-purity material. The proposal is not a substitute for all primary production: the report’s argument is that recovering scrap could complement it and reduce dependence on imports and smelter-made metal.

Why Aluminum Scrap Gets Lost
Aluminum is recyclable, but recovering it at useful quality requires more than collecting cans. Scrap from vehicles, equipment and other products can include different metals and alloys, and mixing those materials can reduce the value of what remains after processing. U.S. scrap is often shipped overseas for hand sorting or shredded and melted into lower-value products, according to the Canary Media report.
Current sorting lines also have practical limits: material moves quickly, and systems can miss recyclables when they are overloaded or components fail. Greyparrot’s cameras are designed to monitor what passes through a facility and identify missed material. Sortera’s approach targets separation of specific aluminum alloys. These examples show companies applying new tools, but the source material does not establish how widely the systems are operating or their overall national effect.
““It’s a secure supply chain issue.””

How Much Scrap Can Be Recovered?
The available figures do not show how much additional aluminum advanced sorting could recover across the country, how much of that material would meet buyers’ quality requirements, or how quickly it could reach the market. Greyparrot’s 89% finding applies to aluminum passing through one Brooklyn facility; it should not be read as a U.S. average or as proof that 89% of aluminum waste nationwide is recoverable.
The report calls for policy action, but the supplied material does not identify adopted federal incentives, funding levels, or a timeline for legislation. It also does not quantify the costs of installing and operating newer equipment against the value of the recovered metal.
Policy and Plant Results Ahead
The Center for Strategic Industrial Materials is calling for federal incentives and more research funding for advanced sorting technologies. Whether policymakers adopt those proposals, and whether states change recycling rules, remains unknown based on the available reporting.
Further evidence will come from how technologies perform as they are used at more facilities: whether they raise recovery rates, produce aluminum that buyers can use, and reduce the amount of valuable material sent to landfill. For now, the report identifies a potential supply source, while the scale and economics of recovering it remain open questions.
Key Questions
Why is aluminum scrap ending up in landfills?
Scrap can be mixed with other metals or contain different aluminum alloys that are difficult to separate. The report also points to uneven recycling policies and sorting systems that can miss material.
How much energy does recycled aluminum use?
The source report says recycling aluminum uses about 5% of the energy needed to make virgin aluminum in a smelter.
Does the 89% figure apply to all U.S. recycling plants?
No. Greyparrot said it found that 89% of aluminum passing through one Circular Services facility in Brooklyn was recyclable. The figure is not a national average.
What policy changes are being proposed?
The Center for Strategic Industrial Materials is urging federal incentives and increased research funding for advanced sorting technologies. The supplied report does not say those measures have been adopted.
