Assessment of Electronic Waste Management Environmental Pollution and Associated Health Risks in Gazipur City Bangladesh
This study assesses the 2024 E-waste generation and management landscape in Gazipur City, Bangladesh, revealing that informal recycling practices pose significant environmental and health risks due to inadequate infrastructure and weak policy implementation, while proposing a framework for sustainable management through Extended Producer Responsibility and circular economy strategies.

Every day, the world produces a mountain of discarded electronics. From the refrigerator that stops cooling to the television that refuses to turn on, these items are not just trash; they are complex mixtures of valuable metals and dangerous poisons. When these devices are thrown away without care, they release toxic substances like lead and mercury into the soil and air, harming the people who live nearby and the workers who try to break them down. In many developing nations, the system for handling this waste is not run by large, regulated companies but by a vast network of individuals who buy, sell, and dismantle old electronics in their own backyards or small workshops. This informal system keeps valuable materials in circulation and provides jobs, but it often does so at a terrible cost to human health and the environment. Understanding how this system works, where the waste goes, and what it costs the community is essential for building a safer future.
In the bustling industrial city of Gazipur, Bangladesh, a team of researchers set out to map this hidden world of electronic waste. They focused on a single year, 2024, to measure exactly how much waste was generated and to follow its journey from the moment a household or business decided to discard an item. The city, located just north of the capital, Dhaka, is a hub for manufacturing and a rapidly growing urban center, making it a critical place to study how a modernizing society deals with its obsolete technology. The researchers did not rely on guesswork; they walked through neighborhoods, visited repair shops, and spoke directly with hundreds of people, from families in their homes to the owners of scrap markets and the officials tasked with managing the city. By combining these conversations with direct observations of how waste was handled, they built a complete picture of the flow of materials through the city.
The study found that Gazipur generated a massive amount of electronic waste in 2024, totaling over 6,200 tons. This means that for every person living in the city, about 2.4 kilograms of electronic waste was created over the course of the year. The biggest contributors were large household appliances, specifically refrigerators, televisions, and microwave ovens. These items make up the bulk of what people throw away. When a family in Gazipur decided to get rid of an old device, they rarely took it to a certified recycling center. Instead, the most common path was to sell it to an informal collector or a scrap dealer, known locally as a "Bhangari" shop owner. Nearly half of the households surveyed said they sold their old electronics this way, hoping to get a small amount of money back. Another significant portion of the waste simply sat in people's homes, stored away for years because it still held some value or because the owners did not know what else to do with it.
Once the waste left the home, it entered a complex chain of informal activity. The researchers found that the informal sector was the backbone of the entire system. It was these collectors and shop owners who gathered the waste, sorted it, and often repaired it to sell again. This repair work is a positive aspect of the system, as it extends the life of products and keeps them out of the trash. However, when the items could no longer be fixed, they were passed to dismantlers. Here, the process became dangerous. To extract valuable metals like copper from wires, workers often burned the plastic insulation off the cables in open fires. To pull precious metals from circuit boards, they used strong acids. These activities were done without protective gear, releasing thick clouds of toxic smoke and spilling hazardous chemicals onto the ground.
The human cost of these practices was stark. The researchers discovered that only a tiny fraction of the workers involved in this process wore any kind of safety equipment. Most of them worked with their bare hands, breathing in fumes from burning plastic and handling sharp, dirty metal. Many of these workers reported suffering from respiratory problems, skin rashes, and chronic coughs. The study suggests that these health issues are a direct result of their daily exposure to the toxic substances released during the dismantling process. The danger is not limited to the workers; the smoke and runoff from these informal workshops contaminate the air, soil, and water that the entire community shares.
Despite the existence of national rules designed to manage hazardous waste, the system in Gazipur remains largely unregulated. The researchers found that the city lacks the necessary infrastructure to handle this volume of waste safely. There are very few formal recycling facilities, and the government agencies responsible for enforcement struggle to oversee the thousands of small, scattered workshops. Most businesses and institutions in the city also rely on the informal sector to get rid of their old electronics, often burning wires or dumping waste with regular trash because they have no other option. The study highlighted that while the government has created policies to make manufacturers responsible for the waste their products create, these rules have not yet taken hold in practice.
The path forward, according to the researchers, requires a shift from this fragmented and unsafe system to an integrated one. This would involve building proper collection centers where people can drop off old electronics, creating safe recycling facilities that can extract materials without poisoning the environment, and bringing the informal workers into the formal system. By training these workers, providing them with safety equipment, and paying them fairly, the city could protect their health while still recovering valuable resources. The study concludes that without these changes, the amount of waste will only grow as the city expands, and the risks to public health and the environment will continue to rise. The solution lies in recognizing the value of the informal sector while transforming its methods to ensure that the recovery of resources does not come at the cost of human well-being.
