This is the story of a cellphone. It is purchased by the owner and is used frequently. It has seen many texts, emails, photos, videos, scrolling on social media, and plenty of apps that have come and gone. One day, the owner decides to upgrade to a newer phone. The old phone is discarded and ends up on a ship making its way to China. From there, it goes to an informal recycling center to be dismantled for valuable parts, all while local communities may bear the environmental and health consequences.
What Is E-Waste and Informal Recycling?
E-waste refers to electronic products that have become broken, unwanted, or obsolete. This can include cell phones, tablets, personal computers, household appliances, and other electronic devices. Informal recyclers recover parts and materials from e-waste without the infrastructure, protections, or standardized methods typically associated with formal recycling facilities.
Informal recycling of e-waste can be extremely dangerous because of the toxic materials electronic products may contain. According to the World Health Organization , e-waste can release as many as 1,000 different chemical substances into the environment.
E-waste can be especially harmful to children. Toxic substances can reach a developing fetus through the placenta and may also be transferred through breast milk. Children can also be exposed through waste scavenging, sorting, environmental contamination, or simply by living near informal recycling activity. These exposures may negatively affect critical systems including the nervous, respiratory, and immune systems.
These concerns are particularly relevant to China because of the country’s enormous volume of electronic waste. According to a 2020 United Nations report cited by Reuters , China led the world in e-waste generation with approximately 10.1 million metric tons. That level of domestic generation alone creates significant demand for collection, dismantling, and recycling.
Case Study: Guiyu
The Chinese town of Guiyu exemplifies the dangers historically associated with improper e-waste recycling. It developed an international reputation as a hub for informal recycling, with reports indicating that approximately 75% of households in a population of around 150,000 had been involved in the trade since the 1980s.
Historically, significant quantities of e-waste reaching Guiyu were smuggled into China from developed Western and Asian countries, bypassing laws restricting or banning e-waste imports.
Domestic e-waste has also been collected through hawkers. These collectors travel through neighborhoods and industrial areas offering to take unwanted electronics from residents and businesses. Many are members of economically disadvantaged communities or migrants from rural areas who travel to cities seeking employment.
Once collected, e-waste may be processed using hazardous informal methods. One example is circuit-board baking, or CBB, which is used to extract valuable components from circuit boards and may involve heating, incineration, or chemical processing. Such activities have historically taken place in backyards, workshops, and even residential spaces.
These practices contributed to contamination of the air, water, and soil around Guiyu with heavy metals and other toxic substances.
The pollutants released into the surrounding environment have been associated with negative health effects among residents. Research examining maternal exposure to metals associated with informal e-waste recycling in Guiyu has found associations with lower birth weight and, to a lesser degree, smaller head circumference. Exposure is therefore not limited to individuals directly working in recycling workshops; people living nearby can also come into contact with environmental contaminants.
The Struggle for Effective Solutions
China has long struggled to implement effective solutions to informal e-waste recycling. The country was among the early signatories of the Basel Convention, signing it in 1990 before the agreement entered into force in 1992. The convention is an international agreement intended to minimize hazardous waste, promote responsible waste management, control transboundary waste movement, and combat illegal waste trafficking.
However, international regulation has faced challenges involving definitions of e-waste, distinctions between waste and reusable goods, recycling exemptions, enforcement, and the difficulty of regulating individuals and private firms operating within informal markets.
In 2000, China’s State Environmental Protection Administration issued what became the country’s first major prohibition on imports of many categories of e-waste. Enforcement remained difficult, however, and recyclable materials such as copper and aluminum created incentives and potential pathways for continued imports.
In 2012, Chinese officials introduced certification for formal recyclers and expanded an Extended Producer Responsibility, or EPR, system commonly known as the fund policy. The program sought to make producers financially responsible for products after their useful lives ended.
These measures nevertheless struggled because of enforcement challenges and competition from the informal sector.
Even with formal e-waste recycling structures in place, China found it difficult to eliminate informal recycling. One reason was that some recycling centers lacked the necessary equipment or adequate government support to process particular forms of electronic waste. Material that could not be handled formally could therefore find its way back into informal channels.
Another challenge was that informal recyclers could sometimes outperform formal systems in convenience, collection expertise, accessibility, and the amount of compensation offered to consumers for unwanted electronics.
Effective Solutions
In 2017, China made significant progress in cracking down on imported waste through the Implementation Plan on Banning Imports of Foreign Garbage and Advancing the Reform of the Solid Waste Import Administration System.
The policy tightened restrictions on imported waste and changed the treatment of materials associated with the recovery of metals such as copper and aluminum. Reports indicate that these changes, together with domestic enforcement and formalization efforts, substantially reduced Guiyu’s traditional informal recycling industry. International attention to the environmental conditions in Guiyu also placed pressure on authorities to formalize much of the area’s recycling infrastructure.
Researchers have proposed going further by creating a stronger closed-loop economy for electronics. Tingting Tian and colleagues have identified several potential components of such a system.
- Improve the existing fund policy with economic incentives, including mechanisms such as consumer deposits that could expand the funding pool while encouraging formal e-waste recycling.
- Establish policies requiring certain products to incorporate recycled materials.
- Invest in the construction and modernization of formal e-waste recycling centers, including systems that make use of e-commerce and digital collection networks.
- Encourage technological innovation within the formal recycling industry.
One example of what a more formalized circular-economy system can achieve is China’s Ziya Circular Economy Park. The park has been supported by broader circular-economy development efforts and the United Nations Development Programme’s Shifting to Zero Waste Against Pollution initiative.
According to the United Nations Development Programme , the park generated approximately $2.45 billion in output in 2024 while recovering roughly 1.5 million tons of valuable materials such as copper and aluminum. The project has also become part of international circular-economy cooperation involving Central Asian countries.
Broader recommendations for improving the circular economy have also been developed by the International Labour Organization. These include using public procurement and investment to encourage circularity, providing resources to sustainable enterprises, developing education and training programs, enforcing occupational health and safety standards, and improving data collection so that governments and researchers can better monitor circular-economy employment and activity.
Protecting pregnant workers and people of reproductive age from hazardous e-waste exposure is particularly important because toxic substances associated with improper recycling can affect fetal development. Ultimately, effective solutions must protect workers and surrounding communities while creating viable economic alternatives to unsafe recycling practices.
Conclusion
If there is anything to learn from China’s experience with informal e-waste recycling, it is that the environmental cost of technology does not disappear when a device leaves a person’s hands.
Consumers, manufacturers, recyclers, and governments all have roles to play in ensuring electronics are handled responsibly. For individuals, one of the most practical steps is making sure unwanted electronics are taken to reputable recycling programs rather than simply discarded.
When electronics are collected responsibly, valuable materials can be recovered and returned to productive use. Building that kind of circular system can reduce pollution, protect communities, conserve resources, and help ensure that the next generation of technology does not come at the expense of the people living where yesterday’s devices are dismantled.
