Basel Action Network E-Waste Report Exposes AI’s Hidden Hardware Problem

Basel Action Network now estimates that AI-linked equipment could create up to 617 million tonnes of electronic waste by 2050. The Basel Action Network e-waste report reaches that figure by counting far more than processors and servers. It includes the electrical, cooling, networking, storage, and backup systems that keep AI data centers operating.

That broader boundary produces a projection many times larger than earlier research focused mainly on computing hardware. At the upper end, the retired equipment would fill about 23 million 40-foot shipping containers. Lined up, those containers would circle the planet roughly six times.

The headline number is a forecast, not a measured outcome. Yet the report exposes an immediate problem for cloud providers, equipment manufacturers, recyclers, and regulators. AI’s physical footprint does not end with electricity and water. Every new data center also creates a future stream of obsolete machinery, hazardous materials, and recoverable metals.

The AI E-Waste Estimate Just Became Much Larger

The new estimate changes the accounting boundary, not merely the growth assumption.

The nonprofit Basel Action Network, or BAN, published its analysis on September 15, 2026. It projects that 395 million to 617 million tonnes of AI-related electronic equipment will be retired between 2025 and 2050.

The upper estimate equals about 23 million shipping containers. Even the lower estimate represents a waste stream far beyond the server-focused projections that have shaped discussion so far.

BAN estimates annual retirements could reach between 8.6 million and 13.1 million tonnes by 2030. The organization describes this as roughly 40 to 60 times some estimates centered on servers and graphics processors.

That difference begins with what BAN places inside the system boundary. A data center needs servers, but it cannot function with servers alone. It also requires switches, storage devices, power distribution equipment, batteries, generators, cooling machinery, cables, and other specialized hardware.

The report says server-focused research overlooks about 87 percent of a data center’s broader electromechanical infrastructure. BAN therefore applies a full-infrastructure model that assigns about 70,000 tonnes of equipment to each gigawatt of data center capacity.

Capacity projections then drive the forecast. The model draws on estimates that global data center capacity could reach 219 gigawatts by 2030. Extending equipment replacement across later expansion scenarios produces BAN’s cumulative range through 2050.

The method also includes what the organization calls “AI waste contagion.” This category covers related telecommunications equipment and personal devices that AI development might cause owners to replace earlier.

That is the model’s most expansive and uncertain component. A server retirement can be connected directly to a data center upgrade. It is harder to determine whether an AI feature caused a consumer to replace a phone or computer.

BAN’s central finding remains important even if that category receives a cautious reading. The full-infrastructure estimate identifies equipment that narrower studies often leave outside their models.

A discarded graphics processor is visible and easy to associate with AI. Retired cooling pumps, switchgear, backup batteries, network switches, and power systems attract less attention. Together, they can outweigh the computing equipment inside the same facility.

This expanded scope explains why the report is not simply another warning based on faster model growth. BAN argues that much of the future waste was missing before anyone debated the growth rate.

The result reframes every announced AI campus as a delayed waste-management commitment. Construction determines not only near-term electricity demand, but also the quantity of equipment that someone must eventually reuse, recycle, store, or discard.

Why AI Data Centers Create a Hardware Replacement Cycle

AI infrastructure becomes waste through repeated replacement, not one distant demolition event.

Data centers contain equipment with different useful lives. Servers may be upgraded while a building remains operational. Batteries, cooling components, drives, and networking gear follow separate maintenance and replacement schedules.

AI accelerates that cycle because operators compete on performance per watt, computation density, and service cost. A newer accelerator can process more work within a constrained power envelope. That can make functioning older equipment commercially unattractive before it physically fails.

The resulting waste is not limited to broken hardware. It includes equipment retired because a newer system offers better economics. Some devices can enter secondary markets, but others have specialized designs or limited resale demand.

Large AI clusters also reshape the systems around them. Higher rack densities require different cooling arrangements, power delivery, networking, and physical layouts. Replacing the computing layer can therefore force changes elsewhere in the facility.

This creates a conflict between rapid deployment and long equipment life. Cloud providers want each generation of hardware online quickly. Waste reduction works best when equipment stays useful longer, receives repairs, or moves into a second-life application.

Earlier research captured part of this pressure. A 2024 peer-reviewed study estimated that generative AI could accumulate 1.2 million to 5 million tonnes of e-waste from 2020 through 2030. Its model focused particularly on large language model computing equipment.

The same generative AI study found that circular strategies could reduce modeled waste by 16 to 86 percent. Those strategies included extending hardware life, reusing equipment, and improving material recovery.

A separate 2026 academic analysis reached a lower near-term estimate. It projected that AI servers could produce 131,000 to 224,800 tonnes of e-waste annually by 2030.

That server-focused reassessment concluded that AI might contribute less to global e-waste than earlier estimates suggested. It also stressed the lack of supply-chain data and realistic server-lifespan information.

At first glance, that conclusion conflicts with BAN’s numbers. The studies are not measuring exactly the same thing, however. One emphasizes AI servers, while BAN attempts to count the surrounding infrastructure and induced device replacement.

This distinction matters because “AI e-waste” has no universally accepted accounting boundary. Analysts can count accelerators, entire servers, full facilities, connected telecommunications assets, or consumer devices affected by AI adoption.

Each choice answers a different question. A server-only model can estimate the direct hardware burden of computation. A full-system model is better suited to examining the waste obligations created by an infrastructure buildout.

BAN’s report therefore does not automatically invalidate the academic estimates. It challenges whether their boundaries are wide enough for policy and long-term waste planning.

The competing results reveal a deeper transparency problem. Outside researchers generally lack complete equipment inventories, retirement schedules, refurbishment rates, and final disposal records from major data center operators.

Without those records, models must combine public capacity projections with assumptions about equipment mass and lifespan. Small changes compound across decades, especially when forecasts extend to 2050.

The uncertainty is real, but it does not make the hardware disappear. It shows why operators should report physical assets with the same seriousness applied to energy consumption and carbon emissions.

The Basel Action Network E-Waste Report Puts Recyclers Under Pressure

The AI buildout is creating specialized waste faster than recycling systems are becoming transparent and accountable.

The world generated 62 million tonnes of e-waste in 2022, according to the Global E-waste Monitor. Only 22.3 percent was documented as formally collected and recycled in an environmentally sound manner.

The global waste inventory projects annual e-waste generation will reach 82 million tonnes by 2030. That growth was already expected before BAN applied a broader definition to AI infrastructure.

BAN estimates AI-related equipment could eventually represent 15 to 20 percent of global e-waste. It compares that share with a projected worldwide total of 211 million tonnes annually by 2050.

Those figures should not be treated as a guaranteed outcome. They combine long-term data center growth, equipment intensity, replacement cycles, and global waste projections. Every component can change.

Still, the scenario shows the capacity problem facing recyclers. Data center equipment contains valuable copper, aluminum, steel, circuit boards, and other recoverable materials. It can also contain batteries and substances requiring controlled handling.

Collection is only the first challenge. Modern electronic products combine materials in ways that complicate separation. Recovering bulk metals is generally easier than extracting smaller quantities of critical materials from integrated components.

Recyclers also need reliable information about what is arriving. Equipment inventories, component composition, service history, and data-security requirements affect whether hardware can be reused or must be dismantled.

Data-bearing devices create another obstacle. Companies may destroy usable storage equipment to prevent information leakage. Secure erasure and verified chain-of-custody systems can preserve reuse options, but they require planning before retirement.

The AI sector has incentives to recover some equipment value. Accelerators, servers, and network devices can remain useful for less demanding workloads. Parts can also support repairs or secondary deployments.

However, reuse depends on software support, energy efficiency, compatibility, and buyer access. A functioning server might carry little practical value if its operating costs exceed those of newer equipment.

That tension makes design decisions important. Modular systems allow operators to replace individual components instead of entire assemblies. Standard parts and repair documentation can also extend useful life.

Manufacturers influence those choices, but hyperscale customers possess leverage. Cloud providers order equipment in enormous volumes and often help shape custom designs. Their procurement rules can require repairability, material disclosure, and take-back services.

Recycling plans must also cover the facility around the server. Power supplies, cooling equipment, batteries, cables, and network systems follow different reuse and recovery channels. A single contractor may not manage every stream well.

The pressure therefore lands across an entire chain. Data center owners decide when equipment leaves service. Manufacturers control design information. Logistics providers move retired assets, and recyclers determine which materials return to production.

Any break in that chain can turn recoverable equipment into exported scrap or landfill waste. The scale in BAN’s forecast makes fragmented accountability increasingly difficult to defend.

Export Rules Expose AI’s Waste Geography

The hardest question is not only how much equipment gets retired, but where it goes afterward.

Electronic waste often moves across borders because labor, treatment costs, and environmental controls vary widely. A shipment labeled for reuse can contain equipment that has little remaining value.

The Basel Convention governs international movements of hazardous and other controlled wastes. Its electronic-waste amendments took effect on January 1, 2025, expanding prior-informed-consent controls for international e-waste shipments.

Under that process, an exporting country generally needs written consent from relevant importing and transit countries before a controlled shipment proceeds. The rules aim to prevent unwanted waste from reaching places without safe treatment capacity.

The United States has signed but not ratified the Basel Convention. That places the largest market for AI infrastructure outside the treaty’s full party framework, although domestic and destination-country rules can still restrict shipments.

BAN has long focused on this regulatory gap. Its investigations have tracked discarded electronics leaving wealthier markets for processing in countries with weaker enforcement or substantial informal recycling sectors.

A 2025 investigation identified shipments of American electronics moving to destinations in Southeast Asia and the Middle East. Authorities in several receiving countries were already increasing seizures and enforcement activity.

The export investigation described workers dismantling equipment without adequate protection. Such processing can release toxic smoke, contaminated dust, and hazardous residues.

AI equipment will not automatically follow those routes. Major operators can require certified processing, audit vendors, and maintain records from retirement through final treatment.

The risk grows when equipment passes through brokers and multiple downstream companies. Each transfer can weaken visibility into whether an asset was reused, recycled properly, stored indefinitely, or dumped.

Corporate recycling totals do not always answer that question. A company might report the percentage diverted from landfill without disclosing final destinations or the recovery rate for individual materials.

Likewise, “recycled” does not mean every component became a new product. The term can cover processes ranging from careful material recovery to low-value shredding with substantial residual waste.

The report’s policy argument rests on closing these visibility gaps. BAN wants stronger controls on waste exports, independent recycling certification, and clearer responsibility for equipment through its entire life cycle.

Extended producer responsibility offers one route. Such rules make producers responsible for financing or organizing collection and treatment after products reach the end of their useful lives.

That approach can shift waste costs toward companies that influence design. It may also encourage products that last longer, separate more easily, or retain value in secondary markets.

However, data center infrastructure does not fit neatly into consumer-device programs. Custom equipment, business-to-business sales, leased hardware, and global cloud operations require rules designed for industrial technology.

International alignment matters for the same reason. A strict program in one market has limited reach if retired equipment can move through another jurisdiction with weaker reporting.

The expansion of AI infrastructure makes this regulatory mismatch harder to ignore. Hardware operates inside national borders, but supply chains and waste markets are global.

The Biggest Number Is Also the Most Uncertain

BAN’s forecast is a warning scenario, not a precise measurement of waste that has already been produced.

The organization is an environmental watchdog with a clear policy position on hazardous-waste exports. Its analysis should be assessed as advocacy research, not confused with a peer-reviewed scientific consensus.

Several assumptions can move the projection sharply. Future data center capacity might grow faster or slower than expected. Equipment intensity per gigawatt could change as facilities improve density and efficiency.

Hardware lifespans are equally important. Extending an average service life reduces the number of replacement cycles before 2050. Shorter cycles increase both manufacturing demand and retirement volumes.

The model must also distinguish replacement from waste. A retired accelerator sold to another operator has left its original data center, but it has not reached end of life. Treating retirement and disposal as identical would overstate immediate waste.

BAN frames its range around electronic equipment retired from service. Readers should therefore avoid interpreting every tonne as material sent directly to a landfill during the forecast period.

Second-life use can delay disposal by years. Yet it does not eliminate the final waste obligation. Equipment eventually reaches a point where repair, resale, or redeployment is no longer practical.

The “AI waste contagion” category introduces another layer of uncertainty. AI features may encourage device upgrades, but consumers replace devices for many overlapping reasons. Separating those causes is difficult.

Forecasts through 2050 also depend on technologies that do not yet exist. Future accelerators might use fewer materials per unit of computation. New cooling designs could reduce equipment mass, or denser deployments could require more specialized systems.

Policy can change the result as well. Repair requirements, recycled-content standards, producer-responsibility laws, and export controls would alter both waste volumes and treatment pathways.

These uncertainties weaken claims of exactness, but they strengthen the case for better disclosure. Operators could replace assumptions with measured data by publishing equipment counts, mass, age, reuse rates, and verified destinations.

Comparable reporting would also resolve disagreements between narrow and broad estimates. Researchers could show server waste separately from supporting infrastructure without collapsing both into one number.

A useful disclosure framework would track at least four stages: equipment purchased, equipment deployed, equipment retired, and equipment reaching final treatment. Reuse should remain separate from recycling.

Companies should also report material recovery rather than relying only on unit counts. One reused server and one recycled cooling system represent different environmental outcomes.

The strongest response to BAN’s forecast is not to accept every upper-bound assumption. It is to demand enough operational evidence to replace uncertain estimates with auditable records.

Until then, both industry assurances and external projections remain difficult to verify. The information gap favors optimistic claims because the waste appears years after infrastructure announcements receive public attention.

Three Signals Will Show Whether the Forecast Holds

Capacity growth, equipment longevity, and verified recovery will determine whether AI approaches BAN’s upper estimate.

The first signal is the pace and composition of data center construction. Announced capacity does not always become operational capacity. Delays involving power connections, financing, permits, or chip supply can change retirement projections.

More important, developers should publish equipment intensity alongside megawatts. Two facilities with equal power capacity can contain different quantities of cooling, backup, networking, and computing hardware.

If deployed capacity approaches current high-growth forecasts without lower material intensity, BAN’s range becomes more plausible. Slower construction or lighter infrastructure would weaken the upper case.

The second signal is the actual service life of AI hardware. Operators rarely provide consistent public data showing how long accelerators, servers, and supporting systems remain deployed.

Watch for evidence that older accelerators are moving into inference, research, or secondary-market workloads. A functioning resale channel would reduce near-term waste and improve the economics of longer hardware use.

Manufacturer support also matters. Software compatibility, spare parts, repair access, and firmware updates can decide whether older equipment remains useful.

If cloud providers replace systems after only a few years without substantial redeployment, annual waste will rise quickly. Longer service and documented second lives would push outcomes toward the lower end.

The third signal is verifiable downstream recovery. Corporate sustainability reports should identify how much equipment was reused, refurbished, recycled, and sent for final disposal.

Those reports should also name treatment regions and describe audit methods. A recycling percentage without destination data cannot show whether hazardous material moved into poorly controlled processing.

Regulators can reinforce this signal through shipment records and enforcement. The Basel e-waste rules provide a framework for consent and international tracking, although national participation and enforcement remain uneven.

Transparent reporting would let customers compare cloud providers on more than speed, model access, and electricity claims. Enterprise buyers could include equipment-life and recovery requirements in infrastructure procurement.

Developers and knowledge workers have less direct control, but their purchasing decisions still influence demand. Choosing appropriately sized models and extending device life can reduce pressure at the edge of the system.

The Basel Action Network e-waste report ultimately challenges the idea that AI exists mainly as software. Every model depends on physical systems with finite working lives and complicated destinations.

The 617 million-tonne estimate may fall as technology, policy, and reuse practices improve. It may also prove conservative if capacity and replacement cycles accelerate together.

What matters next is whether operators disclose enough evidence to tell the difference. Ask providers how long their equipment stays in service, where retired systems go, and how recovery is verified. Those answers will reveal whether AI’s hardware boom is building a circular supply chain or simply postponing a much larger waste crisis.
