Sri Lanka faces a growing environmental crisis as the Centre for Environmental Justice (CEJ) has sounded the alarm over the staggering volume of sulfuric acid being released into the country's environment each year. According to the organization, more than 5,000 metric tons (MT) of sulfuric acid are discharged annually as a direct consequence of informal and poorly regulated lead-acid battery recycling operations across the island. The warning has sparked urgent calls for stronger regulatory enforcement, improved waste management infrastructure, and greater public awareness about the dangers posed by hazardous battery waste.
The Scale of the Problem
Lead-acid batteries are among the most widely used energy storage devices in Sri Lanka, powering everything from motor vehicles and motorcycles to backup power systems and industrial equipment. While these batteries are essential to modern life, their disposal and recycling present serious environmental and public health challenges. Each lead-acid battery contains a significant quantity of sulfuric acid, which serves as the electrolyte enabling the battery to function. When batteries are improperly dismantled or recycled without adequate containment measures, this acid is released directly into the surrounding soil, waterways, and drainage systems.
The CEJ estimates that the cumulative volume of sulfuric acid released through these processes exceeds 5,000 metric tons every single year in Sri Lanka alone. This figure represents a massive environmental burden, particularly for communities living near informal recycling sites, scrap yards, and battery repair workshops where safety standards are often minimal or entirely absent.
Environmental and Health Consequences
The release of sulfuric acid into the environment carries severe consequences for both ecosystems and human health. When acid enters soil, it alters pH levels dramatically, rendering land infertile and destroying the microorganisms that sustain healthy agricultural conditions. Contaminated soil can persist in a degraded state for years, affecting food production and local livelihoods long after the initial pollution event.
Water contamination is equally alarming. Sulfuric acid runoff into rivers, streams, and groundwater sources acidifies these vital resources, killing aquatic life and making water unsafe for drinking, irrigation, and livestock use. Communities that depend on wells and surface water sources near recycling hotspots are particularly vulnerable to exposure through contaminated drinking water.
Human health impacts are wide-ranging and serious. Prolonged exposure to sulfuric acid fumes and contaminated water has been linked to respiratory illnesses, skin conditions, eye damage, and gastrointestinal problems. Workers involved in informal battery recycling operations face the greatest direct risks, often handling corrosive materials without proper protective equipment. Children living near these sites are also at heightened risk, as developing bodies are far more susceptible to the toxic effects of acid exposure and the heavy metals frequently associated with battery waste, particularly lead.
Informal Recycling: The Root Cause
At the heart of this crisis lies the widespread prevalence of informal battery recycling in Sri Lanka. While formal recycling facilities equipped with proper acid neutralization systems and containment infrastructure do exist, a significant proportion of used batteries are handled by informal operators who lack both the equipment and the knowledge to manage hazardous materials safely. Economic pressures often drive battery owners to sell used batteries to the cheapest available buyer, frequently informal collectors who prioritize profit over environmental responsibility.
The CEJ has highlighted that the absence of a comprehensive, enforced extended producer responsibility (EPR) framework for battery manufacturers and importers allows this situation to persist. Without mandatory take-back schemes or clearly defined accountability for end-of-life battery management, the burden of disposal falls disproportionately on communities and the environment rather than on the industries that profit from battery sales.
CEJ's Recommendations and Calls to Action
The Centre for Environmental Justice has outlined several key recommendations to address the sulfuric acid pollution crisis. Foremost among these is the urgent establishment and enforcement of a formal, regulated battery collection and recycling system that ensures all used lead-acid batteries are processed through facilities capable of safely handling hazardous materials, including proper acid neutralization and disposal.
The organization is also calling on Sri Lanka's Central Environmental Authority and relevant government ministries to strengthen monitoring and enforcement activities targeting illegal and informal recycling operations. Regular inspections, meaningful penalties for violations, and accessible reporting mechanisms for communities affected by pollution are all cited as essential components of an effective regulatory response.
Additionally, the CEJ is advocating for public education campaigns to raise awareness among battery users, mechanics, and small business owners about the proper channels for battery disposal and the serious risks associated with improper handling.
A Moment for Decisive Action
The CEJ's warning serves as a critical reminder that environmental protection requires proactive governance, industry accountability, and informed public participation. With over 5,000 metric tons of sulfuric acid entering Sri Lanka's environment every year, the cost of inaction is measured not only in ecological damage but in the health and wellbeing of communities across the country. Addressing this challenge demands immediate, coordinated action from regulators, industry stakeholders, and civil society alike before the damage becomes irreversible.
