Haphazard recycling of the used lead-acid battery (crude smelting process) around a mega city like Dhaka contaminates air, water and soil with toxic substances is a clear threat with various health hazards to people, especially children.

Recycling might be the best way unless we have a sustainable alternative(s). There should be a proper guideline on how to recycle used lead-acid batteries and only approved recyclers should do this business by preventing environmental contamination.
