Recycled lead used in U.S. auto batteries linked to poisoning in African communities

Key Concepts

• Recycled Lead: Lead extracted from used batteries, often for reuse in new batteries.
• Supply Chain Opacity: The lack of transparency and traceability in the complex network of producers, intermediaries, and consumers involved in a product's journey.
• Lead Poisoning: A serious health condition caused by exposure to lead, leading to irreversible neurological damage, particularly in children.
• Smelters: Facilities where metal ores are melted down to extract the metal.
• Pickers: Individuals who collect discarded batteries for recycling.
• Breakers: Workers who manually dismantle batteries to extract lead.
• Noxious Clouds/Lead Dust: Harmful airborne particles released during lead recycling processes.

Investigation into U.S. Car Battery Lead Supply Chain

This report details an investigation by The New York Times and The Examination, a nonprofit newsroom, into the supply chain of lead used in U.S. car batteries. The investigation uncovered a disturbing reality: recycled lead, often promoted as an environmental success story, is linked to dangerous lead poisoning in communities in Nigeria where the recycling takes place.

Lead Recycling Process in Nigeria

The investigation traced the supply chain of U.S. car batteries to villages in Nigeria. The process involves:

1. Collection: Individuals known as "pickers" collect discarded car batteries across Nigeria.
2. Dismantling: These batteries are brought to yards where "breakers" use machetes to break open the plastic casings.
3. Lead Extraction: Workers, often using their bare hands, extract the lead from inside the batteries.
4. Transportation: The extracted lead is then transported by truck to smelters in specific towns.
5. Smelting: At these smelters, the lead is placed in extremely hot furnaces and melted down into liquid form.

Health Impacts and Environmental Contamination

The smelting process releases significant pollution:

• Noxious Clouds and Lead Dust: The furnaces produce thick, black smoke and lead dust.
• Environmental Contamination: This lead dust and soot rain down on people's homes, laundry, and the dirt where children play.
• Community Exposure: Residents living in villages adjacent to these factories are directly exposed to this lead pollution through inhalation.

Evidence of Lead Poisoning

The investigation conducted blood tests on 70 individuals from these Nigerian villages who agreed to participate. The results were alarming:

• High Lead Levels: Seven out of ten individuals tested showed harmful levels of lead in their bodies.
• Reported Health Issues: Villagers consistently reported symptoms indicative of lead poisoning, including:
  • Constant stomach pain
  • Children not sleeping
  • Coughing
  • Sinus infections
  • Distended bellies
  • Relentless headaches
• Impact on Children: Schools located near the factories reported children having difficulty concentrating, a symptom linked to lead poisoning's irreversible brain damage.

The Opacity of the Global Supply Chain

Peter Goodman, global economics correspondent for The New York Times and part of the reporting team, highlighted the deliberate opacity of this supply chain:

• Global Phenomenon: The issue is not confined to Nigeria; similar practices are occurring in numerous other developing countries. Nigeria is identified as the fastest-growing source of recycled lead exported to the U.S.
• U.S. Regulations and Demand: Stricter environmental regulations in the U.S. have driven domestic lead smelters out of business to prevent lead poisoning within the country. Simultaneously, increased demand for lead, driven by growth, has outstripped the capacity of remaining domestic plants.
• Seeking Overseas Sources: This combination of factors has led U.S. automakers and battery manufacturers to seek lead from overseas, including Nigeria, to supplement their supply.
• Denial of Responsibility: The intricate network of participants and countries involved allows each entity to plausibly deny responsibility for the conditions at the ground level in places like Nigeria.

Economic Desperation and the "Bargain"

The investigation also shed light on the economic realities driving these practices:

• Meager Opportunities: The villages are described as being full of people "coaxing substance from meager opportunities."
• Dependence on Factories: Despite the dangers, the lead recycling factories provide crucial employment.
• Low Wages: Jobs in these facilities are extremely low-paying, with one individual interviewed earning approximately one dollar a day for working from 7 AM to 7 PM, six days a week.
• Acceptance of Risk: Even those aware of the health risks, like the man tested with very high lead levels, did not want the factories closed due to the lack of alternative economic opportunities.
• The "Bargain": The supply chain tends to shift the "dirtiest and most dangerous things" to places where leaders will make a "bargain," accepting risks like lead poisoning in exchange for jobs.

Desire for Change

Despite their economic dependence, the villagers expressed a strong desire for improvement:

• Minimizing Pollution: They want to see the pollution minimized and are eager for the implementation of equipment that limits lead exposure in their communities, similar to what is present in the U.S.

Conclusion

The investigation reveals that the U.S. automotive industry's reliance on recycled lead from developing countries like Nigeria, while seemingly an environmental solution, comes at a severe human cost. The opaque global supply chain allows for the externalization of dangerous lead recycling processes, leading to widespread lead poisoning and health crises in communities that have few other economic options. The findings challenge the narrative of recycled lead as a purely positive environmental practice and highlight the ethical implications of globalized manufacturing.
