A significant portion of this waste originates from the shipbreaking industry, contributing over 2.7 million metric tons each year . The remaining e-waste comes from discarded consumer electronics, including mobile phones, televisions, and computers.DOE Portal+2jrrecyclingsolutionsltd.com.bd+2pmc.ncbi.nlm.nih.gov+2lightcastlepartners.com+1DOE Portal+1
Mobile Phones: A Growing Concern
With the widespread adoption of mobile technology, Bangladesh sees approximately 30 million mobile phones discarded annually. Over the past 21 years, mobile phones have contributed approximately 10,504 metric tons of toxic e-waste in the country . This surge is attributed to rapid technological advancements and consumer trends favoring frequent device upgrades.
Environmental and Health Impacts
The improper disposal and recycling of e-waste, particularly mobile phones, pose significant environmental and health risks.
Environmental Impacts
- Soil and Water Contamination: Toxic metals from e-waste can leach into the soil and groundwater, leading to long-term environmental degradation.
- Air Pollution: Open burning of e-waste releases harmful dioxins and furans into the atmosphere, contributing to air pollution.
Health Impacts
- Occupational Hazards: Workers in informal recycling sectors are exposed to hazardous substances without adequate protection, leading to respiratory issues, skin disorders, and other health problems.
- Community Health Risks: Communities near e-waste recycling sites face increased risks of cancer, neurological disorders, and developmental issues in children due to environmental contamination.
A study revealed that more than 15% of child workers involved in e-waste recycling in Bangladesh die due to exposure to toxic substances, and over 83% suffer from long-term illnesses .
Current E-Waste Management Practices
E-waste management in Bangladesh is predominantly handled by the informal sector, which accounts for up to 97% of e-waste recycling activities . This sector employs low-paid workers who often lack awareness of safety measures, leading to unsafe processing methods such as:thefinancialexpress.com.bd
- Manual Dismantling: Using rudimentary tools without protective gear.
- Open Burning: To extract valuable metals, releasing toxic fumes.thefinancialexpress.com.bd+2DOE Portal+2ipen-china.org+2
- Acid Bath Leaching: Using hazardous chemicals to recover metals, resulting in chemical exposure and environmental contamination.DOE Portal
These practices not only endanger workers but also contribute to environmental pollution, affecting broader communities.
Regulatory Framework and Challenges
In response to the growing e-waste problem, the Bangladeshi government introduced the Hazardous Waste (E-Waste) Management Rules in 2021 . These regulations aim to:
- Define Responsibilities: Assign duties to producers, dealers, refurbishers, collection centers, consumers, dismantlers, and recyclers.jnu.ac.bd
- Establish Procedures: Set guidelines for authorization, storage, transportation, and disposal of e-waste.jnu.ac.bd
- Promote Safe Practices: Encourage environmentally sound recycling and disposal methods.
However, enforcement remains a significant challenge due to:
- Lack of Infrastructure: Insufficient formal recycling facilities to handle the volume of e-waste.
- Informal Sector Dominance: The prevalence of informal recycling makes regulation difficult.
- Public Awareness: Limited understanding among consumers and workers about the hazards of improper e-waste handling.
