When Waste Stops Being Waste and Becomes a Strategic Reserve
The starting point for these thoughts was a White House decision that, at first glance, could easily disappear within the constant flow of news about international trade, energy and competition between the world’s major powers.
On 30 July 2026, the US government designated a range of materials recoverable from end-of-life products as resources essential to national defence and security. These include the black mass produced during battery processing, rare-earth permanent magnets, swarf and residues from metalworking, as well as other waste and scrap containing critical minerals and materials.
The decision does not, by itself, impose a general ban on exports. It does, however, authorise the Secretary of Commerce to intervene, under the Defense Production Act, in how these materials are distributed and allocated.
What might previously have been treated simply as industrial residue or electronic waste has therefore acquired a different legal and strategic significance. It is no longer merely something that must be removed and managed safely. It is a potential source of lithium, cobalt, nickel, copper, graphite, tungsten and rare earth elements—the materials required for batteries, semiconductors, electricity grids, electric vehicles, defence systems and digital infrastructure.
Waste is beginning to be treated as a strategic national reserve.
The circular economy moves to the centre of geopolitics
For many years, the circular economy was discussed primarily in environmental terms. We spoke about reducing waste, protecting the natural environment, improving recycling and limiting the excessive consumption of raw materials.
All of these remain critically important. But they no longer represent the entire picture.
Critical minerals have moved to the centre of energy, economic and national-security policy. In its 2026 outlook, the International Energy Agency warns that the processing of these materials remains highly concentrated in a small number of countries, while export restrictions are turning theoretical supply-chain risks into real disruptions.
Lithium prices more than doubled within a relatively short period. Cobalt prices increased by approximately 130%, while tungsten prices rose sixfold. In Europe, certain rare earths and critical metals now cost several times more than they do within the Chinese domestic market.
This is not simply another fluctuation in commodity markets. It reflects an industrial reality in which a limited number of countries control a very large proportion of mineral extraction, processing and conversion into materials that industry can actually use.
In such an environment, every battery, electronic device, motor, cable or industrial component that reaches the end of its useful life is no longer merely a waste-management problem. It is a potential point at which a valuable material can re-enter production.
That fundamentally changes the meaning of waste.
Knowing how much waste we collected is not enough
Having worked professionally with waste-management systems, I believe this is where one of the greatest misunderstandings surrounding the circular economy begins.
We often evaluate the success of a system by measuring how much material was collected or how much was reported as having been sent for recycling. These indicators are useful, but they do not answer several more important questions.
What materials are actually contained within that stream? At what concentration and in what condition? Where were they generated? Who owns them? How are they transported? At which facility do they eventually arrive? Which technology can recover them? Is there an industry ready to purchase and use the resulting secondary material?
A country does not have a circular economy simply because it collects waste.
It has a circular economy when it knows which materials it possesses, where they are located, who controls them, how they can be separated, where they can be processed and who has an economic incentive to keep them within the productive cycle.
Without this knowledge, circularity remains more of a policy ambition than a real industrial capability.
The problem is not only technological
Battery-recycling technology has already matured considerably. According to the US Government Accountability Office, recycling could help reduce dependence on imports of copper, cobalt, lithium and nickel within two to three years.
The GAO, however, identifies the central problem: US recycling facilities still lack sufficient capacity, while significant quantities of suitable material are either sent to landfill or exported for processing.
This reveals a reality that is often hidden behind announcements of new technologies.
You may have an effective recovery process without reliable access to the right material. You may have collection systems without domestic processing facilities. You may have facilities without buyers for the recovered product. You may have ambitious targets without economic incentives capable of making the activity commercially sustainable.
A recycling plant without sufficient and predictable feedstock risks becoming a stranded investment. Collection without domestic processing may simply export value to another country. Processing without adequate quality standards may produce materials that cannot re-enter demanding industrial applications.
The circular economy is not a single technology. It is an entire chain that must operate without critical gaps.
Even the value of waste changes
There is another aspect that is often avoided: not every form of recycling is automatically economically viable.
The value of recovered materials is influenced by international commodity prices, chemical composition, purity, transport costs, safety requirements and the technology needed to separate them.
Changes in battery chemistry offer a characteristic example. Lithium iron phosphate batteries have gained a significant share of the market because they rely less on expensive materials such as nickel and cobalt. This can be an advantage during manufacturing, but it reduces the residual value of the battery at the end of its life and makes the economics of recycling more difficult.
The material remains important. Its recovery, however, may not be sufficiently financed by the value of the products obtained from it.
This is where public policy, extended producer responsibility schemes, mandatory targets, guaranteed markets and long-term offtake agreements become important. Economic incentives do not always emerge naturally from the market. Sometimes they must be deliberately designed.
Data is part of the infrastructure
When dealing with strategic materials, traceability is not a supplementary administrative function. It is part of the productive infrastructure itself.
The International Energy Agency and the OECD have stressed that the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for building more resilient and responsible supply chains.
The same logic must apply when materials move from product status to waste status.
We need reliable data about composition, quantities, origin, location, movements, treatment operations and final outcomes. We need common classifications, interoperability between systems and the ability to verify that a material actually arrived at the destination reported for it.
Data does not recover lithium or cobalt by itself. It does, however, determine whether the right material reaches the right facility, at the right time and with the right quality for recovery to become possible.
Without this digital infrastructure, it is remarkably easy to produce flawless compliance reports without knowing whether we have created any real circularity.
The world already possesses enormous reserves outside its mines
According to the Global E-waste Monitor produced by the ITU and UNITAR, the world generated 62 million tonnes of electronic waste in 2022. Only 22.3% was documented as having been formally collected and recycled in an environmentally sound manner.
This waste contained metals with an estimated value of $91 billion. Yet only part of that value was recovered, while electronic-waste recycling currently satisfies only around 1% of global demand for rare earth elements.
These figures illustrate both the size of the opportunity and the scale of the failure.
We have created enormous material reserves within our cities, homes, warehouses, businesses, waste-management facilities and landfill sites. Urban mining is not merely an attractive environmental metaphor. It is the recognition that significant quantities of raw materials are now embedded in products we have already manufactured.
The problem is that we do not always know where they are, what condition they are in or whether they can be returned to production at a competitive cost.
Export restrictions are not enough
The US decision may help retain critical materials within the country. But it should not be mistaken for an automatic solution.
If a country restricts the export of a material without possessing adequate processing capacity, effective collection systems and industrial buyers, it risks creating accumulated stockpiles that it cannot use.
Industrial sovereignty is not achieved simply by keeping waste within national borders. It is achieved when that waste can be converted back into a reliable raw material and used within a domestic or allied production chain.
The same applies to Europe, which has set a target for recycling capacity to cover 25% of its annual consumption of strategic raw materials by 2030. This is an important objective, but achieving it will require much more than regulation: processing facilities, investment, energy, expertise, markets for secondary materials and reliable data across the entire chain.
From waste management to resource management
The most important change is not technological. It concerns the way we understand what waste actually is.
For decades, the central question was how to remove it safely and at the lowest possible cost. Today, we must also ask which materials we are losing, who ultimately captures their value and from whom we will need to purchase them again in the future.
Waste management is gradually becoming a form of economic and industrial intelligence. Information about material flows may prove just as important as the facilities that eventually process them.
A country, company or city that knows precisely which materials it possesses, where they are located and how they can be returned to production acquires a different level of resilience.
Perhaps, then, we should stop treating waste as the end of economic activity.
It is the beginning of a new value chain—provided that we have built the systems capable of seeing it, recording it and using it.
Because anyone who treats waste only as a cost risks paying for it twice: once to remove it, and again to import the materials they allowed to disappear.
