Emerging concerns associated with E-waste exposure in Bangladesh

Area of Science:

• Environmental Science
• Public Health
• Waste Management

Background:

• Rapid urbanization and industrialization are escalating global electronic waste (E-waste) generation, posing significant management challenges.
• Bangladesh faces a critical need for effective E-waste management strategies and increased public awareness.
• This research provides a comprehensive analysis of Bangladesh's E-waste situation, its environmental and health impacts, and current governmental policies.

Discussion:

• Improper E-waste management in Bangladesh has led to severe environmental contamination, with soil lead levels reaching 587 ppm in 2023, far exceeding WHO guidelines.
• Air and dust pollution are significant concerns, with high concentrations of Zinc (2175 ppm) and Nickel (1986 ppm) detected.
• Water contamination is a persistent issue stemming from inadequate E-waste landfilling practices.

Key Insights:

• The study quantifies the severe environmental degradation caused by unchecked E-waste in Bangladesh.
• Existing management strategies like public-private partnerships (PPP) and willingness to pay (WTP) require augmentation.
• Incorporating take-back and collection (TBC) and recognition-based (RB) systems can significantly improve E-waste handling.

Outlook:

• This research offers a foundational framework for developing a comprehensive E-waste management policy in Bangladesh.
• Implementing suggested strategies can substantially mitigate the adverse environmental and health effects of E-waste.
• The findings aim to guide authorities in establishing a sustainable E-waste management system for a healthier future.
