Growing evidence of severe lead contamination linked to battery recycling is raising fresh concerns about environmental and public health impacts in Kenya and across Africa, as demand for lead-acid batteries continues to rise.
A series of studies and field reports indicate that soil, air and water contamination around recycling sites can reach levels far above internationally accepted safety thresholds, with long-term consequences for nearby communities.
Research into battery recycling operations across several African countries, including Kenya, has found widespread contamination of surrounding land. Soil samples taken near formal recycling plants showed average lead concentrations of around 2,600mg/kg in nearby communities – more than 30 times higher than levels considered safe for children.
At some sites, contamination is significantly worse. Measurements inside facilities have reached tens of thousands of mg/kg, with peak levels reported as high as 140,000mg/kg.
These findings point to battery recycling as a major source of environmental lead exposure, particularly in regions where regulatory oversight and pollution controls are limited.
Kenya case highlights long-term impacts
Kenya has become a focal point for these concerns. In the coastal settlement of Owino Uhuru, near Mombasa, a former lead-acid battery recycling plant – operated from 2007 by Kenya Metal Refineries EPZ, a local subsidiary of an India-based company – has been linked to widespread poisoning among residents. Community members allege that waste from the site, which processed and exported recovered lead, contaminated surrounding soil and water, contributing to illness and more than 20 associated deaths. Although the facility closed in 2014, contamination persists in soil and water supplies, with communities continuing to report health effects.
Mother of four, Faith Muthama, 40, told Associated Press that she has suffered long-term health problems: “Life has never been the same. I still struggle to do heavy chores as I suffer from breathing difficulties. When I was tested in 2012, I was found with high lead levels in my blood.”
Investigations have shown that exposure pathways include contaminated dust, soil ingestion and polluted drinking water – particularly affecting children, who are most vulnerable to lead toxicity.
Separate occupational studies have also highlighted risks within the industry itself. Measurements at Kenyan recycling and manufacturing plants have recorded airborne lead concentrations far exceeding recommended limits, alongside elevated blood lead levels in workers.
Structural issue linked to battery demand
The issue is closely tied to the growth of lead-acid battery use across Africa. These batteries remain widely used in automotive applications, backup power systems and increasingly in off-grid solar installations.
As a result, recycling capacity is expanding – but often without the corresponding investment in emissions control, waste handling or site remediation.
Industry analysts note that lead-acid batteries are among the most recycled products globally, but poorly managed operations can turn recycling sites into significant pollution sources if best practices are not followed.
Lee Crawford, senior research fellow at the Centre for Global Development, told Associated Press:“Off-grid solar could account for a substantial share of batteries entering the recycling stream in Africa. That’s on top of existing demand from vehicles like cars and motorbikes.”
Regulatory gaps and industry implications
A recurring theme across studies is the lack of dedicated regulatory frameworks governing lead battery recycling in many African countries. In several cases, facilities operate under general environmental legislation rather than sector-specific standards, limiting enforcement of emissions controls and remediation obligations.
Experts are calling for tighter controls, including mandatory pollution abatement systems, routine monitoring of blood lead levels in nearby populations, and financial provisions for site clean-up after closure.
