Why e-waste is becoming an issue
Level
What happens to your old phone when you're done with it? Or that drawer full of tangled chargers and forgotten devices? As our appetite for new technology grows, so does the pile of discarded electronics we leave behind, creating one of the fastest-growing waste streams in the world: electronic waste, otherwise known as e-waste.
“ E-waste is a growing environmental threat. From toxic components that can leach into soil and water to the valuable raw materials being lost, the way we manage our electronic waste has far-reaching consequences for both people and the planet. ”
In this article, we'll unpack the growing problem of e-waste, exploring what’s driving it, the risks it poses, and the solutions that could help us build a more sustainable future in a digital world.
What is e-waste? A quick overview
“ E-waste, short for electronic waste, refers to discarded electronic devices that are no longer wanted or useful. Think old smartphones, laptops, TVs, fridges, and even that drawer full of tangled cables and broken chargers. Such equipment often still contains valuable materials, but is frequently thrown away instead of being reused or recycled. ”
It’s the waste stream no one wants to think about, but it’s growing fast. In our rush to upgrade to the latest tech, perfectly functional devices are often pushed aside. New models hit the shelves every year, making older ones feel outdated long before they stop working. And with this cycle of constant consumption comes a surge in electronic waste.

Why is e-waste a problem?
“ The scale of e-waste produced globally is hard to ignore – and it’s only getting worse. In 2022 alone, the world generated 62 million tonnes of electronic waste, according to the UN. That’s a staggering 82% increase since 2010. And the trend isn’t slowing down. By 2030, global e-waste is expected to hit 82 million tonnes. ”
So what’s driving this surge? A mix of factors: constant tech innovation, shorter product lifespans, and our growing appetite for electronic devices. Together, they’ve made electrical and electronic waste the fastest-growing solid waste stream on the planet.
But the real issue isn’t just the volume, it’s what happens to all that waste. Right now, only about 17% of e-waste is properly recycled. The rest often ends up in landfills or is handled informally, releasing toxic substances into the environment and wasting valuable materials like gold, copper, and rare earth metals that could be recovered.
Close
What is e-waste made of?
E-waste isn’t just a pile of broken gadgets, it’s a complex mix of valuable materials and electronic components, many of which also contain toxic substances.
On one hand, discarded electronics contain precious metals like gold, copper, silver, and lithium - valuable secondary raw materials that could be recovered and reused. On the other hand, they also house hazardous elements like lead, mercury, and cadmium, along with flame retardants and other chemicals that pose serious risks to both human health and the environment.
Recycling e-waste isn’t as simple as tossing it in the bin. Safely separating and recovering these materials requires specialized equipment and procedures to avoid contamination and protect workers.
Here’s a breakdown of what commonly makes up e-waste:
| Component | Examples | Value or Risk |
|---|---|---|
| Precious metals | Gold, silver, copper, platinum, lithium | Valuable – can be recovered and reused in new electronics |
| Plastics | Casings, circuit board insulation | Some can be recycled, but may contain flame retardants |
| Glass | Screens, CRT monitors | Recyclable, but can contain lead and other heavy metals |
| Hazardous substances | Lead, mercury, cadmium, brominated flame retardants | Toxic – harmful to humans and ecosystems if not properly handled |
| Other components | Batteries, capacitors, wiring | Contain valuable or dangerous materials, depending on the type |
E-waste trends
The latest UN Global E-waste Monitor (2024) reveals some striking trends about how electronic waste is evolving and the growing scale of the problem. It’s not just phones and laptops piling up, but also smaller, everyday gadgets and even newer products like disposable vapes that are adding to the crisis.
Here are some of the most eye-opening findings from the report:
Disposable vapes are creating a new waste stream
Once overlooked, disposable e-cigarettes have now emerged as a growing e-waste issue. With sales expected to grow by 31% annually until 2030, these devices are often tossed in the trash due to the lack of systems for recycling batteries, metals, and plastics they contain.
Small electronics make up a third of global e-waste
Items like microwaves, smart speakers, electric toothbrushes, and IoT gadgets are responsible for roughly one-third of global e-waste. But with only 12% currently recycled, most end up in landfills.
Mobile phones and laptops remain major contributors
Small IT equipment accounts for over 11 billion pounds of e-waste. Software updates and end-of-support policies (like Microsoft ending Windows 10 support) accelerate device obsolescence, potentially rendering 400 million PCs unusable.
The US leads in per capita e-waste
The average American produces 47 pounds (21.3 kg) of e-waste each year, among the highest globally. The country generates nearly 8 million tonnes annually, yet only 15% is recycled.
Rare earth elements are rarely recycled
Despite being vital for electronics and green tech, less than 1% of rare earth elements are recovered through recycling – the rest come from environmentally damaging mining operations.
New tech production far outpaces recycling
Global recycling efforts recover around 30 billion pounds of materials each year, but the rate of new electronics production is five times higher, highlighting the urgent need for reuse and repair strategies.
Regional breakdown: E-waste generation vs recycling:
The UN’s data shows stark regional disparities in both how much e-waste is generated per person and how much of it is actually recycled:
| Region | E-waste generated per capita (kg) | Formally recycled per capita (kg) | Recycling rate |
|---|---|---|---|
| Europe | 17.6 | 7.53 | 42.8% |
| Oceania | 16.1 | 6.66 | 41.4% |
| Americas | 14.1 | 4.2 | 30.0% |
| Asia | 6.4 | 0.76 | 11.8% |
| Africa | 2.5 | 0.018 | 0.7% |
| World average | 7.8 | 1.75 | 22.3% |
The environmental and health impacts of e-waste
The effects of e-waste aren’t always easy to see, but they’re far-reaching. When electronic devices are dumped or dismantled without proper safeguards, the consequences can be devastating for the environment and for human health, especially in parts of the world where informal recycling is widespread.
Environmental impact: what happens when electronics break down
Most electronic devices are made from a mix of materials – metals, plastics, and chemicals – some of which are highly toxic materials if not handled correctly. When e-waste is dumped in landfills or burned to extract metals, these materials don't just disappear. They leak into the soil, the water, and the air.
Here’s how e-waste damages the environment:
Toxic chemicals in soil and water
Electronics often contain heavy metals like lead, mercury, and cadmium. When devices break down in landfills, these substances can seep into the soil and contaminate groundwater, affecting crops, drinking water, and entire ecosystems.
Air pollution from open burning
In many informal recycling sites, burning is used to recover valuable metals like copper. But this process releases dangerous toxins like dioxins and furans—persistent organic pollutants linked to cancer, hormonal disruption, and respiratory diseases.
Impact on biodiversity
The chemicals released through improper e-waste disposal don’t just affect humans—they also harm wildlife. Animals and plants can absorb these toxins, leading to genetic mutations, reproductive problems, and disruptions across the food chain.
Health risks: the human cost of improper recycling
“ Much of the world’s e-waste is sent to developing countries where informal recycling is common. Workers, often unprotected and underpaid, manually dismantle electronics using unsafe methods. The health risks are immense, especially for children involved in this work. ”
Organizations like the World Health Organization and the International Labour Organization have warned that stronger safeguards are needed to protect human health, particularly for vulnerable groups such as children and pregnant women, due to the long-term effects of exposure to e-waste toxins.
Key health impacts include:
Direct exposure to toxic substances
Handling electronics without protective gear exposes workers to chemicals that can cause skin rashes, lung damage, neurological issues, and more.
Long-term and chronic health effects
Prolonged exposure to heavy metals and flame retardants is linked to cancer, kidney failure, developmental disorders, and reproductive health problems.
Severe risks to children
Children are especially vulnerable. In some regions, they’re directly involved in dismantling and burning electronics, exposing their developing bodies to toxins that can lead to lifelong health issues and developmental delays.
“ The environmental and health issues associated with e-waste don’t stop at the border. Much of the world’s electronic waste is exported from wealthier nations to countries with fewer regulations and limited recycling infrastructure. This raises serious ethical questions about who bears the risks and how we can ensure a more just and sustainable global system for dealing with waste. ”

Why is e-waste becoming such an issue?
To tackle the growing mountain of electronic waste, we first need to understand what’s driving it. The rise in e-waste isn’t just a byproduct of our digital lives, it’s fuelled by a mix of rapid tech innovation, consumer habits, and global economic forces that make proper recycling difficult.
Let’s break it down:
Shorter lifespans by design: New models of smartphones, laptops, and other devices are released so often that older ones quickly become outdated, even if they still work. In many cases, this is by design. Known as planned obsolescence, this trend pushes people to upgrade frequently, creating a steady stream of waste.
Harder to repair: Modern electronics are often built in ways that make repairs difficult or expensive — glued parts, hard-to-access batteries, and proprietary tools. As a result, fixing a broken device can cost more than buying a new one, so most people just replace.
Chasing the latest tech: We live in a culture where having the latest gadget is a status symbol. Marketing hype, new features, and peer pressure all play a role in encouraging frequent upgrades — even when devices are still fully functional.
Low awareness of disposal options: Many consumers don’t realize that electronics need to be recycled separately, or don’t know where or how to do it. As a result, old devices are often tossed in the trash, stored in drawers, or handed off to informal recycling channels that lack safety standards.
Recycling isn’t always easy: Proper e-waste recycling is expensive and complex. Not every region has the infrastructure to support it, and in some places, the cost of setting up safe recycling systems is prohibitive. Without convenient, affordable options, even willing consumers are left without good choices.
A global waste trade: Large volumes of e-waste are exported from developed to developing countries, where environmental regulations may be weaker and recycling costs are lower. But this shift often means e-waste is handled in unsafe conditions, posing serious risks to workers and local ecosystems.
All of these factors combine to create a growing global challenge, one that won’t be solved by consumers alone, but through systemic change in how we design, buy, and dispose of our electronics.

The toxic trade: exporting e-waste to developing nations
While wealthier countries often tout their recycling efforts, a troubling reality persists: a significant portion of electronic waste is exported to developing nations under the guise of second-hand goods or for recycling.
“ In 2022 alone, approximately 5.1 million tonnes of e-waste crossed international borders, with an estimated 65% (about 3.3 million tonnes) shipped from high-income to low- and middle-income countries through undocumented or illegal channels. ”
This practice, sometimes referred to as "toxic colonialism", disproportionately burdens communities in countries like Ghana, Nigeria, and Malaysia.
In places such as Agbogbloshie, Ghana, workers, including children, dismantle electronics using rudimentary methods like open-air burning or acid baths to extract valuable metals. These processes release hazardous substances, including lead, mercury, and dioxins, contaminating the environment and posing severe health risks.
Despite international agreements like the Basel Convention, which aims to regulate hazardous waste movements, enforcement remains inconsistent. Loopholes allow exporters to label e-waste as reusable electronics, circumventing regulations. Recent crackdowns, such as Malaysia's seizure of over 100 containers of illegal e-waste in 2024, highlight the ongoing challenges in curbing this illicit trade.
“ The export of e-waste to developing countries not only endangers local communities but also undermines global environmental justice. Tackling e-waste dumping requires stronger international cooperation, stricter enforcement of existing laws, and a commitment from developed nations to manage their electronic waste responsibly. ”

E-waste legal regulations
As the volume of electronic waste continues to climb, governments around the world are racing to keep up with legislation. From global treaties to new national rules, efforts are underway to reduce the environmental and health impacts of e-waste, but progress is uneven.
The Basel Convention regulates how hazardous waste, including e-waste, moves across borders — aiming to prevent wealthier countries from dumping toxic waste in low-income nations without consent.
As of 2025, the Ban Amendment is in force for most signatories. It prohibits hazardous waste exports from OECD to non-OECD countries — but enforcement varies.
New this year: Starting January 2025, both hazardous and non-hazardous e-waste fall under Prior Informed Consent (PIC) procedures. Exporters now need written approval from destination countries before shipping e-waste — a move meant to improve transparency and ensure environmentally sound management of electronic waste.
The WEEE Directive remains the EU’s main regulation on e-waste. It requires producers to fund the collection and recycling of electrical or electronic equipment and sets minimum recovery targets.
As of 2025, the directive is under review as part of the European Green Deal. Updates are expected to improve collection rates and support circularity.
E-waste types are also classified under the European Waste Catalogue, helping standardize tracking across member states. New Battery Regulations also apply, covering sustainability from raw materials to recycling.
The UK’s WEEE regulations remain closely aligned with the EU post-Brexit. Producers must fund take-back schemes and meet collection and recycling targets.
From January 2025, importers face new responsibilities under the updated WEEE framework. The UK has also announced a ban on single-use vapes, coming into effect in June 2025, to curb electronic waste from disposable e-cigarettes.
The US still lacks a federal e-waste recycling law. Instead, 25 states and Washington D.C. have enacted their own rules — some based on extended producer responsibility, others using upfront recycling fees.
However, momentum is building nationally. In early 2025, bipartisan legislation was reintroduced to set consistent rules for e-waste exports and domestic recycling — with the goal of limiting shipments to developing nations.
Outside the EU, UK, and US, many governments are stepping up efforts — but progress is mixed.
India: The E-Waste (Management) Rules now require manufacturers to meet growing Extended Producer Responsibility (EPR) targets — currently 20% of prior year sales. A new provision mandating minimum payments to authorized recyclers has triggered pushback from tech brands over cost concerns.
China: China aims to build a nationwide recycling system by the end of 2025. It plans to reuse 60% of urban household waste. Oversight is improving, but informal streams remain widespread.
Southeast Asia & Africa: In many regions, informal recycling remains dominant. Workers handle toxic materials without protection, and regulatory enforcement is limited. Infrastructure and funding gaps still pose major obstacles to safe, scalable e-waste management.
While regulations are improving globally, a clear gap remains between rules on paper and what happens in practice, particularly in countries receiving large volumes of exported e-waste from wealthier nations, highlighting the urgent need for more coordinated efforts to address the global e-waste problem.
Why e-waste regulation is still falling short
Even in countries with strong laws on paper, managing e-waste effectively is a major challenge. Enforcement is often patchy, infrastructure is lacking, and illegal exports continue to undermine progress.
Here are some of the key barriers:
But globally, progress is uneven. Many countries still lack clear targets, enforcement mechanisms, or producer responsibility schemes.
What can we do to reduce e-waste?
As the mountain of electronic waste continues to grow, so does the urgency to find smarter, more sustainable ways to deal with it. Fortunately, there are promising solutions emerging from new technologies and policy reforms to better design and more informed consumers.
Recycling is getting better and smarter. New technologies now allow recyclers to extract valuable materials like gold, silver, copper, and rare earth metals from old electronics more efficiently and safely than ever before.
These innovations reduce the amount of waste ending up in landfills and help cut down on the environmental cost of mining new resources. For example, researchers are developing specialized methods to recover metals from circuit boards, part of a broader shift toward more efficient waste processing, ensuring that such precious materials don’t go to waste and could dramatically lower emissions tied to raw material extraction.
E-waste is partly a behavioral issue. Many people still don’t know what to do with their old electronics or why it matters.
That’s why public awareness is key. From school campaigns and collection drives to clearer labeling and easy drop-off points, making recycling simple and accessible can go a long way. On the flip side, consumers can also make more conscious choices by buying repairable, longer-lasting products and resisting the pressure to upgrade too often.
Policy can make or break e-waste management. Governments play a critical role in:
- Setting strong recycling and collection targets
- Enforcing rules around producer responsibility
- Supporting eco-design standards and innovation
- Cracking down on illegal exports
International cooperation is especially important, since e-waste often crosses borders. Aligning efforts across countries can help ensure that waste is treated safely, no matter where it ends up.
More tech companies are starting to take responsibility for the products they put out into the world. That includes:
- Take-back programs, where consumers can return old devices for recycling
- Designing products for disassembly, making them easier to repair or recycle later
- Using recycled materials in new devices
These moves not only help reduce waste but also support a shift toward a circular economy, where materials are reused rather than discarded.
“ The future of e-waste management depends on a mix of technology, responsibility, and collaboration. That means better product design, smarter systems for recycling and reuse, and stronger global partnerships to tackle the problem at scale. ”
