## **The mounting tide of e-waste**
The modern digital age has a dirty side, and it’s not just overflowing landfills—it’s a specific and rapidly growing category of trash: electronic waste, or e-waste. From cellphones to computers to massive server farms, our society is discarding electronics at an unprecedented rate. This problem is poised to explode further due to a single, dominant industry trend: Artificial Intelligence.
Solomon Njoroge’s story is a stark illustration of this global issue. He began picking through trash at the Dandora dumpsite, a sprawling 40-acre landfill outside Nairobi, before he could even remember his teens. He has witnessed firsthand the human cost, seeing fellow waste pickers fall victim to asthma, cancer, miscarriages, and respiratory diseases. The Dandora dump is not a single villain’s doing; it is the physical manifestation of decades of collective choices by governments, corporations, and individuals on how to deal with unwanted goods.
The modern era has added a potent new toxin to this equation: electronics. Discarded gadgets are now the fastest-growing category of waste on the planet. According to projections, humans will generate 82 million metric tons of e-waste annually by 2030. The AI boom is set to turbocharge this problem. Researchers from the United Nations University estimate that the hardware turnover from AI data centers alone could generate about 2.5 million metric tons of waste annually—the equivalent of 250 Eiffel Towers.
> “Inasmuch as we are working for development or greatness to change the world… [hyperscalers] should also consider that there are people somewhere, suffering from what they are calling greatness,”
This is the central conflict. The data centers powering AI are often massive, warehouse-like facilities filled with thousands of servers, networking equipment, and storage drives. These hyperscale centers have lifespans measured in years, not decades. As the AI race accelerates, these powerful systems are being replaced faster than ever. This rapid turnover creates a logistical and environmental nightmare. Much of this hardware contains toxic materials like arsenic, lead, cadmium, and mercury. When improperly disposed of, these substances leach into soil and water, contaminating ecosystems and food chains far beyond the original dump site.
The question becomes: where does all this hardware go? In the United States alone, over 1,500 data centers are in various stages of development. While not all will end up in a landfill, the sheer volume of hardware requires a solution. Often, that solution is shredding. While this can prevent data leaks, it creates its own set of hazards, releasing toxic dust into the environment if not handled with extreme care.
The UN has acknowledged the scale of the challenge. In a resolution proposed by Kenya, member states agreed that AI must be developed and deployed sustainably. This calls for greater transparency in the environmental impact of the entire AI value chain.
### **Circularity: The promise of a circular economy**
A key concept being championed by major tech companies is “circularity”—the idea that products and their components should be designed for reuse, refurbishment, and recycling. Microsoft, for instance, has pledged to achieve zero waste by 2030. To this end, it has built “Circular Centers” on the campuses of its data centers. These facilities are dedicated to decommissioning hardware. Old servers and components are either refurbished for internal use, sold to third parties, sent to specialized recycling partners to recover valuable metals, or donated to other organizations.
Google’s 2025 environmental report highlights its “reverse supply chain,” through which it harvested and reused or resold 8.8 million hardware components in 2024. The goal is to keep valuable materials in the economy for as long as possible, reducing the need for virgin resources and the creation of e-waste.
However, this transition is not happening fast enough for the people living and working on the front lines of the e-waste crisis.

## **A seat at the table: The vital role of waste pickers**
For Solomon Njoroge and the thousands of waste pickers like him, grand corporate sustainability plans are meaningless without their inclusion. Handling e-waste is back-breaking, dangerous work. Waste pickers burn wires to recover copper, dissemble complex electronics for circuit boards and precious metals, and sort materials for resale. In many parts of the world, this work is a necessity, providing the only income available for people living in extreme poverty.
This work also provides a crucial environmental service. By recovering metals and components, waste pickers reduce the need for new, resource-intensive mining and keep toxic chemicals out of the environment. As one expert noted, these workers are “recovering precious materials that otherwise we’d have to go and mine fresh out of the ground.”
Yet, their contribution is often invisible and unrecognized. They operate in unsafe conditions, without proper personal protective equipment (PPE), ID cards, or safe access to dumpsites. Their children are pulled from school and exposed to the same toxins, leading to severe health problems.
> “Waste pickers are not illegal or informal,” he said, “they are front-line climate workers.”
For Njoroge, a sustainable e-waste future is inseparable from a just transition for the people who manage it. He envisions waste pickers not as a problem to be solved, but as essential partners in the solution. Their involvement is critical when governments and NGOs craft policies around e-waste. Their lived experience is vital for creating safe, effective, and humane systems.
He is looking toward the UN’s 2027 Intergovernmental Negotiating Committee meetings, hoping that a global agreement on managing e-waste will finally recognize the people who are already managing it.

## **Conclusion**
The data center boom fueled by artificial intelligence is locked in a race for speed and scale, but it is leaving a trail of electronic waste that the planet can ill afford. The environmental hazards of e-waste are real and growing, from toxic soil and water contamination to the release of harmful chemicals into the air.
While the tech industry is beginning to embrace concepts like circularity and sustainable design, true solutions cannot be engineered in a vacuum. They must be co-created with the waste pickers who are already on the ground, managing the consequences of our digital consumption. A just and sustainable future for e-waste management depends on recognizing these workers not as a problem, but as the frontline experts in the fight against pollution.

## **FAQ**
**Q: What is e-waste, and why is it a problem?**
**A:** E-waste, or electronic waste, is any discarded electronic device, such as phones, computers, and servers. It is a major environmental hazard because it contains toxic chemicals like lead, mercury, and cadmium. When improperly disposed of, these substances pollute soil, water, and air, posing serious risks to human health and ecosystems. E-waste is also the fastest-growing category of waste globally.
**Q: How is the AI boom contributing to the e-waste problem?**
**A:** The AI boom requires the construction of massive data centers filled with servers, GPUs, and networking hardware. These systems have a relatively short lifespan and are replaced frequently to keep up with technological demands. This rapid turnover generates a massive amount of hardware that becomes e-waste, with estimates suggesting AI data centers could produce millions of metric tons of waste annually.
**Q: What is “circularity,” and are tech companies using it to solve this problem?**
**A:** Circularity is an economic model aimed at eliminating waste and the continual use of resources. In the context of e-waste, it involves designing products for longevity, reusing components, and recycling materials. Companies like Microsoft and Google are implementing circularity strategies, such as “Circular Centers” and “reverse supply chains,” to refurbish, resell, and recycle hardware from their data centers.
**Q: What is the role of waste pickers in the e-waste crisis?**
**A:** Waste pickers are individuals who manually sort, dismantle, and recover materials from discarded electronics. They play a vital role in the informal recycling sector, recovering valuable metals and preventing toxic waste from entering the environment. However, they often work in dangerous conditions without proper protection or recognition for their environmental contribution.
**Q: What is needed to create a sustainable and just solution for e-waste?**
**A:** A comprehensive solution requires a multi-faceted approach. This includes designing hardware for longevity and recyclability (circularity), developing better formal recycling systems, implementing stricter regulations on e-waste disposal, and, most importantly, including waste pickers in the planning and implementation of these solutions. Their expertise and labor are essential for a truly sustainable and just e-waste management system.
