Bangladesh, with its rapidly growing economy and urbanization, has become a key player in South Asia’s electronics manufacturing industry. Among its cities, Dhaka stands out as the hub for electronic manufacturing, contributing significantly to the nation’s electronic waste (e-waste) crisis. This article explores why Dhaka has emerged as the center of this industry, how it contributes to e-waste, and the potential environmental and health challenges that arise from this growth.
Why Dhaka is the Hub for Electronic Manufacturing in Bangladesh
1. Economic Growth and Urbanization
As the capital and largest city of Bangladesh, Dhaka is the economic powerhouse of the country. Its booming urban population, estimated at over 22 million people, drives the demand for consumer electronics. Additionally, the city’s infrastructure, access to skilled labor, and proximity to international trade routes make it the preferred location for electronic manufacturers.
2. Presence of Leading Manufacturers
Dhaka is home to many domestic and international electronics companies producing goods such as televisions, refrigerators, air conditioners, and smartphones. Companies like Walton and Singer have established major production facilities in and around the city, fueling its reputation as an electronics manufacturing hub.
3. Government Initiatives
The Bangladeshi government has introduced policies to encourage domestic manufacturing and reduce import dependence. These incentives include tax breaks and subsidies for companies operating in the electronics sector, many of which are based in Dhaka.
How Dhaka Contributes to E-Waste in Bangladesh
Dhaka’s role as an electronics hub has led to an exponential increase in e-waste generation. Below, we break down the key factors contributing to this phenomenon.
1. High Consumption of Electronics
Dhaka’s affluent urban population frequently upgrades their electronic devices, creating a significant volume of discarded electronics. These items often include mobile phones, computers, and home appliances.
2. Manufacturing Waste
The production processes in Dhaka’s electronics factories generate waste, including defective units, circuit boards, and packaging materials. Without proper disposal mechanisms, much of this waste adds to the city’s growing e-waste problem.
3. Informal Recycling Practices
Most e-waste recycling in Dhaka is handled by the informal sector. Workers often use unsafe methods such as open burning or acid baths to extract valuable materials, which not only reduces recycling efficiency but also creates hazardous byproducts.
E-Waste Statistics in Dhaka and Bangladesh
To understand the scale of the problem, consider the following statistics:
| Category | Statistic | Source |
| Annual E-Waste | 2.81 million tonnes | The Financial Express |
| Contribution by Dhaka | Largest share in the country | Prothom Alo |
| Key E-Waste Sources | Refrigerators (40%), TVs (30%) | The Financial Express |
| Growth Rate | 20% annual increase | The Financial Express |
| Informal Sector | 50,000 children involved in recycling | Prothom Alo |
Environmental Impacts of E-Waste in Dhaka
1. Soil and Water Pollution
Toxic components such as lead, mercury, and cadmium from e-waste often leach into the soil and groundwater. This contamination affects agricultural productivity and water quality, endangering the health of local communities.
2. Air Pollution
Burning e-waste to recover metals releases harmful chemicals into the atmosphere, contributing to air pollution. These emissions include dioxins and furans, which are known carcinogens.
3. Urban Waste Management Crisis
E-waste adds to Dhaka’s already overwhelmed waste management system. Landfills, originally intended for household waste, are now overflowing with electronic components, exacerbating the city’s waste disposal challenges.
Health Risks Associated with E-Waste in Dhaka
1. Exposure to Hazardous Substances
Workers in informal recycling sectors, including children, are exposed to toxic chemicals such as arsenic, beryllium, and brominated flame retardants. Prolonged exposure can lead to respiratory diseases, neurological damage, and cancers.
2. Impact on Vulnerable Populations
Children involved in e-waste processing are at higher risk due to their developing bodies. Studies indicate that these children suffer from impaired cognitive development and chronic illnesses.
3. Broader Public Health Concerns
Improper disposal of e-waste releases pollutants that can spread through air and water, affecting not just workers but also the general population in Dhaka and beyond.
Efforts to Address E-Waste in Dhaka
1. Government Policies
The E-Waste Management Rules 2021 were introduced to regulate e-waste collection, recycling, and disposal. However, enforcement remains weak due to resistance from industry stakeholders and lack of infrastructure.
2. Private Sector Initiatives
Several companies have begun setting up take-back programs and partnering with formal recycling firms to manage their e-waste. For example:
- Walton has introduced an e-waste recycling program targeting discarded appliances.
- Grameenphone has launched awareness campaigns on responsible e-waste disposal.
3. Role of NGOs and International Agencies
Organizations such as the United Nations Development Programme (UNDP) are working with local stakeholders to promote sustainable e-waste management practices in Dhaka.
Recommendations for Sustainable E-Waste Management in Dhaka
1. Strengthen Regulatory Frameworks
- Enforce existing laws with penalties for non-compliance.
- Introduce Extended Producer Responsibility (EPR) to make manufacturers accountable for e-waste recycling.
2. Develop Formal Recycling Infrastructure
- Establish government-funded recycling plants.
- Provide incentives for private investment in e-waste recycling facilities.
3. Promote Public Awareness
- Educate consumers about the environmental and health risks of e-waste.
- Encourage responsible disposal through campaigns and incentives.
4. Integrate Informal Workers
- Offer training programs to informal recyclers.
- Provide safety equipment and formal employment opportunities.
Conclusion: A Shared Responsibility
Dhaka’s status as a hub for electronic manufacturing has brought economic benefits but also significant environmental and health challenges due to rising e-waste. Addressing this issue requires a collaborative effort from the government, private sector, and public to implement sustainable solutions. By investing in proper recycling infrastructure, enforcing regulations, and raising awareness, Dhaka can mitigate the adverse impacts of e-waste and set an example for other cities facing similar challenges.
