Sri Lanka must rethink plastics before waste crisis deepens, says OUSL Vice Chancellor

Sri Lanka is standing at a critical crossroads in its battle against plastic pollution, and the window for meaningful action is narrowing fast. Senior Professor P. M. C. Thilakerathne, Vice Chancellor of The Open University of Sri Lanka (OUSL), has issued a stark warning: the country can no longer afford to treat its plastic problem as a simple waste-disposal challenge. The crisis runs far deeper, threatening coastal ecosystems, marine fisheries, local communities, and the broader public health of the island nation.

Beyond the Bin: A Systemic Problem Demanding Systemic Solutions

For years, Sri Lanka's response to plastic pollution has largely focused on collection drives, landfill management, and periodic bans on single-use plastics. While these efforts are not without merit, Professor Thilakerathne argues they fall dangerously short of addressing the root causes. The country must move beyond simply collecting and disposing of plastic waste and instead rethink the entire lifecycle of plastic — from production and consumption to recovery and alternatives.

This shift in thinking is not merely academic. Sri Lanka generates thousands of tonnes of plastic waste annually, and a significant portion of it finds its way into waterways, rivers, and ultimately the ocean. The consequences are visible and measurable: polluted beaches, declining fish stocks, and microplastics entering the food chain in ways that science is only beginning to fully understand.

Coastal Communities and Fisheries Under Threat

The impact of plastic pollution on Sri Lanka's coastal communities cannot be overstated. The island's fishing industry, which supports the livelihoods of hundreds of thousands of families, is increasingly at risk. Marine debris entangles fishing gear, damages boats, and contaminates catches. More insidiously, microplastics — tiny fragments broken down from larger plastic items — are being found in fish and shellfish consumed by Sri Lankan households every day.

Coastal tourism, another vital pillar of the economy, also suffers when beaches are strewn with plastic waste. Visitors expecting pristine shorelines are instead confronted with debris washed ashore from both local and international sources. The reputational damage to Sri Lanka as a tourist destination compounds the economic losses already felt by fishing communities.

Public Health Consequences Cannot Be Ignored

The public health dimension of Sri Lanka's plastic crisis is increasingly difficult to ignore. Plastic waste that is burned informally — a common practice in rural areas where formal waste collection is limited — releases toxic chemicals into the air, contributing to respiratory illnesses and long-term health complications. Open dumping near water sources creates breeding grounds for disease-carrying mosquitoes, exacerbating existing public health challenges.

Microplastics have also been detected in drinking water sources, raising serious concerns about long-term human exposure. While research into the full health implications is ongoing globally, the precautionary principle demands that Sri Lanka act decisively rather than wait for definitive harm to be proven beyond doubt.

Rethinking Production, Policy, and Public Behaviour

Professor Thilakerathne's call to rethink plastics encompasses three interconnected dimensions: production, policy, and public behaviour. On the production side, manufacturers and importers must be held accountable through extended producer responsibility frameworks that make them financially and operationally responsible for the end-of-life management of their products. Sri Lanka has taken tentative steps in this direction, but enforcement and ambition remain limited.

On the policy front, stronger and more consistently enforced regulations are essential. Bans on certain categories of single-use plastics must be accompanied by viable, affordable alternatives to ensure compliance rather than resistance. Incentive structures that reward businesses and individuals for reducing plastic use and improving recycling rates would help shift behaviour at scale.

Public awareness and education also play an indispensable role. Sri Lankans across all demographics need to understand not just the environmental impact of plastic pollution, but the direct consequences for their health, food security, and economic wellbeing. Institutions like the OUSL are uniquely positioned to lead this educational charge, reaching communities across the country through distance and open learning programmes.

Regional and Global Context

Sri Lanka's plastic crisis does not exist in isolation. The country is part of a broader regional challenge, with South Asia collectively contributing significantly to global ocean plastic pollution. International frameworks, including the ongoing negotiations for a global plastics treaty under the United Nations Environment Programme, offer Sri Lanka both an opportunity and an obligation to align domestic policy with global best practices.

Engaging with these international processes, accessing green financing, and building partnerships with research institutions and development organisations could accelerate Sri Lanka's transition toward a more circular approach to plastics — one where materials are kept in use for as long as possible and waste is minimised by design.

The Time for Half-Measures Has Passed

The message from OUSL's Vice Chancellor is clear and urgent: half-measures and incremental adjustments are no longer sufficient. Sri Lanka must embrace a fundamental rethinking of how it produces, uses, and manages plastics. The cost of inaction — measured in damaged ecosystems, lost livelihoods, compromised health, and a degraded environment for future generations — is simply too high. The moment to act with ambition and urgency is now.
