This is a linked post to work I completed as a volunteer researcher for LABRI. Available on the LABRI blog, where it was published.
Summary. Used lead-acid battery (ULAB) recycling is a key source of childhood lead exposure in Southeast Asia. An estimated one million children in the Philippines and eight million in Indonesia carry blood lead levels high enough to cause developmental harm, and regional productivity losses from lead exposure are estimated at 115 billion USD per year. The post maps the regulations governing ULAB management across all eleven Association of Southeast Asian Nations (ASEAN) countries, produced as volunteer policy research for the Lead-Acid Battery Recycling Initiative (LABRI).
Key findings:
- Transboundary controls are the most consistent dimension of regulation. Nearly all ASEAN countries restrict ULAB imports under the Basel Convention, although enforcement remains uneven and borders are porous.
- Environmental standards for lead in air and water exist almost everywhere but vary widely across the region.
- For ULABs, regulatory specificity varies, ranging from dedicated tracking regimes in Malaysia and Singapore to broad hazardous waste provisions elsewhere.
- Extended Producer Responsibility, which requires manufacturers or importers to manage products at end of life, is unevenly adopted across the region.
Why this matters. ULAB recycling is one of the major causes of lead exposure in low- and middle-income countries. Brazil cut informal recycling by more than half in five years by combining a sales tax exemption with mandatory reverse logistics and producer responsibility obligations. This suggests that similar policy tools could work in ASEAN if adapted to national contexts.
Epistemic status. The analysis is desk research on regulatory frameworks. The comparison reflects the strength of rules on paper rather than verified outcomes on the ground, and data gaps are significant. Myanmar and Laos, for example, have no national blood lead surveys, and ULAB generation and recycling rates are difficult to verify across the region. The mapping is best read as a regulatory baseline rather than a performance ranking.
