Lanka faces looming threat to its environment from haphazard disposal of non-biodegradable face masks

Published

Sri Lanka’s environment is facing a looming threat owing to the haphazard disposal of millions of used face masks and personal protective equipment, reveals a recent study by the University of Kelaniya.

“Mostly, face masks are made of petroleum-based non-renewable polymers that are non-biodegradable, hazardous to the environment and create health issues. It is reported that Sri Lanka generates around 14 to 70 million of face mask waste a week,” said Prof Rangika Bandara, Director of the Centre for Sustainability Solutions of the university’s Department of Zoology and Environmental Management.

She said: “We should understand that disposable face masks which are commonly known as surgical face masks or K-95 masks contain polypropylene which is a popular kind of plastics. According to study findings, a K-95 mask contains about 9 grams of polypropylene and this value is around 4.5 gram in a surgical face mask. By looking at these numbers, it is estimated that as a country Sri Lanka emits 47-185 tons of polypropylene per week to the environment through face masks only.”

“Plastic is considered as a non-biodegradable material as it takes over 500 years to get rid of it from the environment. Disposing facemasks inappropriately on different land surfaces will gradually end up in rivers, lakes, ponds, forests and other vegetation, agricultural fields and finally in oceans by washing them off with runoff and surface flooding and also by wind,” she said.

Prof Bandara said that disposal of used face masks along with other disposable personal protective equipment posed serious risks to valuable global eco-systems creating threats to public health.

According to the health experimental results, wearing a face mask will reduce the risk of transmitting coronavirus by 47% by acting as a particle filter and by minimising the number of times an individual touches the face/mouth/nose with unwashed hands. Therefore, WHO has recommended wearing a suitable face mask appropriately at public places and when interacting with COVID infected or suspected cases. Also, according to the WHO estimates nearly 89 million face masks are needed worldwide to control COVID-19 each month. We should understand that disposable face masks which are commonly known as surgical face masks or K-95 masks contain polypropylene which is a popular kind of plastics. According to study findings, a K-95 mask contains about 9 grams of polypropylene and this value is around 4.5 gram in a surgical face mask.

Prof. Bandara said: “While the soil is contaminated with plastics, soil texture and structure will be altered and become unsuitable for plant growth hence with time, we will not be able to harvest expected yields from agricultural fields. On that day the damage will become irreversible. Not only the soil but also clogging drainage and irrigation channels by waste face masks can be expected. Currently, most of the irrigation and drainage channels in the country, especially in urban areas are already clogged by invasive aquatic weeds such as Eichornia (japan jabara) and Salvinia creating a huge social and environmental problem. Inappropriate disposal of face masks will trigger the problem as they associate with water weeds creating a mesh thereby further blocking water passages. If that is the case, flash floods in cities even in light rains would be unavoidable which is a significant economic loss and greater impact on livelihood specially those who have settled along the water canals.

“Studies carried out in the Mediterranean Sea and ocean bottoms near Hong Kong have shown lining of ocean bottom by layers of face masks which inhibit transfer of oxygen between water and soil in the bottom. With time ocean bottom will create an anaerobic condition which will badly affect the survival of benthic organisms like sea anemones, sponges, corals, sea stars, sea urchins, worms, bivalves, crabs, When the ocean is polluted by facemasks those in settle ocean bottom as well as among aquatic weeds and corals which disturb and disturbed the normal behavioural patterns of aquatic living organisms. Macroorganisms like fishes, jellyfish, and turtles will indigest face masks. This will destroy the eco- system balance and ocean productivity will go down posing a risk to the fisheries industry.

“Plastics will be broken into tiny particles less than 5 micrometres in size and form micro plastics in the form of fibres and/or particulate matter in the ocean, freshwater and marine environment. Different packaging plastic materials, bottling plastic materials and containers from the food processing industries are primary sources of micro plastics pollution. Polypropylene mixed face masks would be another source of micro plastic, especially in ocean and soil. Ultimately, Micro plastics will enter the human body through terrestrial and aquatic food chains causing numerous diseases including different types of cancers.

“As a nation, we have to develop a strategic plan to deal with the post-covid crises. One of the strategies should focus on proper disposal of PPE waste including waste face masks.

If we take examples from the world, countries like China, Canada, Hong Kong, Japan have already identified face masks as an emerging waste category and place bins with a new colour code in public places to separate waste face masks from other type of waste at the point of generation. Incineration of waste face masks is a viable option. Incinerating means burning face masks at high temperatures greater than 1000-1200 centigrade in an incinerator or dumping them in a sanitary landfill after boiling or subjecting to a heat treatment. By practicing this kind of a waste management strategy, we can stop sending waste face masks into different eco-systems. As a nation, we should recognise the importance of waste face masks management by understanding waste face masks and other disposable PPEs as an emerging waste category and should make a waste management plan immediately without further delays. Making this effort a priority by allocating required resources is an investment. Otherwise, we will be desperately looking for solutions to reclaim degraded ecosystems as we drop our agricultural production, fisheries production, increment of vector-borne diseases and other non-communicable diseases, unknown ideologies, losing corals and biological diversity.

Court vacancy row throws Parliament into turmoil; sittings disrupted

Published

Opposition MPs protesting in Parliament yesterday

Parliament proceedings were disrupted yesterday when Opposition MPs staged a protest demanding an immediate debate on the delay in filling vacancies in the Supreme Court and the Court of Appeal, prompting Speaker Dr. Jagath Wickramaratne to suspend sittings.

The tense situation arose when around 20 Opposition MPs sought an emergency debate, under Standing Order 19 (1), citing concerns over judicial vacancies and proposals to increase the retirement age of judges. Kalutara District SJB MP Ajith P. Perera informed the House that a written request, signed by 20 Opposition members, had been submitted to the Speaker earlier in the day.

Responding to the request, Leader of the House and Minister Bimal Rathnayake said the government was unable to accommodate the debate as the day’s agenda included the second reading of the Value Added Tax (Amendment) Bill, two Orders under the Special Commodity Levy Act and regulations under the Imports and Exports (Control) Act, all scheduled for a vote before adjournment.

Kurunegala District SJB MP Dayasiri Jayasekera argued that the Speaker had the authority to grant the request without seeking the concurrence of the government. He maintained that the matter was of urgent public importance and should take precedence over other matters.

As exchanges between government and Opposition members intensified, several MPs, including Opposition and SJB Leader Sajith Premadasa, Harsha de Silva and Dayasiri Jayasekera, voiced strong objections. A number of Opposition MPs moved towards the Well of the House, while some attempted to approach the Mace. Parliamentary security personnel, led by Sergeant-at-Arms Kushan Jayaratne, intervened and prevented any breach of security.

Amid the escalating commotion, Speaker Wickramaratne announced a 10-minute suspension of sittings.

When the House resumed, the Speaker ruled that proceedings would continue in accordance with Standing Orders and called on the government to proceed with the business listed on the Order Paper. Despite continued protests from the Opposition benches, Deputy Minister of Finance and Planning Dr. Anil Jayantha moved the scheduled motions, and the debate on the VAT (Amendment) Bill and related measures resumed.

Climate, pollution, forest loss now hitting economy: BASL chief

Published

BASL President Rajeev Amarasuriya (extreme right) at the launch of Environmental Law Conference 2026 at the Grand Monarch, Thalawathugoda

Climate change, pollution, deforestation and water degradation are no longer abstract environmental concerns but mounting economic threats already affecting Sri Lanka’s power generation, food security, trade, fisheries and tourism, Bar Association of Sri Lanka (BASL) President Rajeev Amarasuriya warned on Saturday.

Addressing the Sri Lanka Public Interest Environmental Law Conference 2026 at Grand Monarch, Thalawathugoda, Amarasuriya said Sri Lanka could no longer afford to treat environmental protection as a secondary policy concern when droughts, shrinking forest cover, polluted water and marine degradation were beginning to carry a direct economic cost.

The conference, organised by the BASL together with the Centre for Environmental Justice (CEJ), brought together judges, lawyers, academics and environmental activists to examine the role of public interest litigation in resolving environment-related disputes and strengthening environmental governance.

In one of the strongest business-focused interventions at the event, Amarasuriya argued that environmental law must now be viewed as an essential part of economic policy, particularly in a country where electricity generation, agriculture, fisheries, tourism and maritime trade are heavily dependent on natural systems.

He said Sri Lanka’s environmental vulnerabilities were now closely intertwined with the performance of key sectors of the economy. Water use in agriculture, for instance, has a direct impact on hydropower generation, while drought conditions can simultaneously hit crop production and reduce electricity output.

Amarasuriya noted that in favourable years, more than 40% of Sri Lanka’s electricity can come from hydropower. Prolonged droughts, therefore, do not merely create ecological stress; they also threaten the energy mix, increase generation costs and deepen wider economic pressures.

Agriculture, he said, remains one of the biggest users of freshwater in Sri Lanka, and pressure on water resources can directly reduce water availability for hydropower generation. The result is a double blow to the economy — stress on food production and added pressure on electricity supply.

He also highlighted the long-term economic implications of forest loss, noting that Sri Lanka has lost more than half of its natural forest cover over the last century. That decline, he warned, is not simply a biodiversity issue. It weakens watersheds, undermines climate resilience, affects water security and damages sectors such as tourism and agriculture that rely heavily on healthy ecosystems.

Amarasuriya said the Sustainable Development Goals should be seen not as separate environmental targets but as part of an integrated development strategy. SDG 13 on climate action, SDG 7 on affordable and clean energy, SDG 2 on climate-smart agriculture and food security, and SDG 15 on forests, biodiversity and mangroves all point to the same reality — that environmental stability is inseparable from economic resilience.

He stressed that forests, wetlands and mangroves are not peripheral ecological assets but productive national resources that strengthen biodiversity, protect coastlines, sustain fisheries and shield communities from climate shocks.

The BASL President also sounded a warning over cross-border pollution, saying Sri Lanka had experienced pollution washing up on its northern shores from beyond its borders, particularly through sea currents from South India. Such incidents, he said, illustrated a basic truth of environmental law: pollution does not stop at political boundaries.

Ocean currents and atmospheric movements allow waste, oil spills and other pollutants generated in one jurisdiction to affect another, he said, adding that Sri Lanka’s strategic position in the Indian Ocean increases its exposure to such risks.

That exposure is heightened by the island’s location on one of the world’s busiest East-West shipping routes. While that gives Sri Lanka major commercial advantages, it also raises the risk of marine pollution incidents and shipping-related environmental damage.

At the same time, he noted that more than 80% of marine pollution originates from land-based activities before entering the sea, showing how failures in waste management and environmental regulation on land can quickly become marine and economic crises.

Amarasuriya said the marine environment should be viewed not only as a natural asset but as a key pillar of trade and national income. Around 90% of Sri Lanka’s international trade is carried by sea, making clean oceans, healthy coastal waters and safe shipping routes essential to the economy.

“Protecting our marine environment is therefore not only an environmental responsibility, but an absolute economic necessity,” he said.

He devoted a significant part of his address to the blue economy, describing it as one of Sri Lanka’s most valuable but under-utilised strategic assets. As an island nation, Sri Lanka’s exclusive economic zone is nearly eight times larger than its land area, creating major opportunities in fisheries, shipping, tourism and other ocean-based industries.

Sri Lanka’s coastline stretches about 3,620 kilometres, while the fisheries sector directly supports the livelihoods of more than 600,000 people. Yet marine pollution, overfishing, habitat destruction and climate change are steadily eroding that economic potential, he warned.

Sustainable fisheries, marine conservation and responsible maritime governance are therefore essential not only for environmental reasons but also to protect jobs, export earnings, food supplies and long-term ocean-based growth.

Amarasuriya also identified water pollution as one of the most serious and persistent threats to the country’s economy and public health. Rivers, reservoirs, groundwater and coastal waters are under pressure from industrial waste, untreated sewage, agricultural runoff and plastic pollution, he said.

The damage is not confined to ecosystems. Polluted water raises health risks, affects productivity, undermines local economies and threatens agriculture, which accounts for a major share of freshwater use in Sri Lanka. With a large proportion of Sri Lankans depending on groundwater and freshwater sources for daily use, contamination of those resources has direct implications for food security, health and livelihoods.

He said stronger regulation, better waste management, improved infrastructure and more effective public participation were urgently needed to prevent further deterioration.

Rejecting the argument that environmental protection is an obstacle to development, Amarasuriya said the opposite was true. Healthy forests, wetlands, fisheries, biodiversity-rich agriculture and clean coastal ecosystems are central to long-term economic growth and stability.

For a country like Sri Lanka — small in size, rich in natural assets and heavily dependent on tourism, agriculture, fisheries and maritime trade — environmental decline translates directly into economic vulnerability, he said.

He noted that more than half of global GDP depends directly or indirectly on nature and ecosystem services, and said Sri Lanka was a clear example of that relationship. The country’s tourism industry, in particular, has long depended on beaches, wildlife, wetlands, forests and biodiversity, while agriculture and fisheries are equally tied to the health of land and water resources.

Environmental protection should therefore be treated as an investment in economic resilience rather than a burden on development, he said.

The conference opened with a welcome address by CEJ Chairman Hemantha Withanage, while Supreme Court Justice Yasantha Kodagoda, PC, delivered the keynote address on public interest litigation in environment-related disputes.

Justice Kodagoda stressed that environmental disputes should not be approached mechanically through litigation alone. Lawyers, he said, must first identify whether a genuine dispute exists, who the disputing parties are, what outcome is sought and whether judicial adjudication is in fact the most suitable mechanism. Environmental disputes may involve the State, private polluters or both, he observed, and in some instances the State itself may be the polluter.

He urged lawyers to think beyond reflexive court action and to consider negotiation, mediation, conciliation and other forms of dispute resolution where appropriate, noting that litigation can be costly, unpredictable and not always the best route to environmental justice.

The first panel discussion, moderated by Attorney-at-Law Vishwa De Livera Tennakoon, examined advancing environmental rights through human rights frameworks and writ jurisdiction, with contributions from Dr. Lalanaath de Silva, President’s Counsel M.A. Sumanthiran, Deputy Solicitor General Dr. Avanti Perera and Prof. Kokila Konasinghe of the Faculty of Law, University of Colombo, who joined virtually.

The second panel, moderated by Dr. Asanka Edirisinghe, Senior Lecturer at the Faculty of Law of General Sir John Kotelawala Defence University, explored how judicial interventions have widened the scope of environmental law. Panellists included Ritwick Dutta, Executive Director and Managing Trustee of the Legal Initiative for Forest and Environment (LIFE), India, who joined online, Dr. Ravindranath Dabare, Attorney-at-Law and Co-Founder of CEJ, and Attorney-at-Law Nuwan Bopage.

The afternoon session also featured a guest speech by Supreme Court Justice Janak de Silva, while the vote of thanks was delivered by CEJ Executive Director Dilena Pathragoda.

Amarasuriya, in his concluding remarks, called for a stronger role for the legal profession, the judiciary, civil society and the media in protecting natural resources, saying environmental protection could not be left solely to governments or international organisations.

Climate change, cross-border pollution, the blue economy, food security and water pollution, he said, were not isolated concerns but interconnected national challenges requiring integrated legal, policy and institutional responses.

Sri Lanka still possessed extraordinary natural assets — forests, mangroves, biodiversity, reservoirs and renewable energy potential — but unless they were managed wisely, the country would pay a rising economic price for environmental neglect, he warned.

GSP+ in jeopardy: GL

Published

on

Prof. Peiris

Former External Affairs Minister Prof. G.L. Peiris has warned that the European Union’s GSP-plus concessions will be jeopardised if the NPP government fail to introduce an internationally acceptable anti-terrorism law in place of the Prevention of Terrorism Act (PTA).

Prof. Peiris issued the warning at a media briefing called by the People’s United Opposition at the Flower Road Office of former President Ranil Wickremesinghe on Monday (22).

Prof. Peiris said lawyers, civil society and professionals strongly opposed the new anti-terrorism law proposed by Justice and National Integration Minister Harshana Nanayakkara six months ago. Having realised that it couldn’t secure the required public support, on behalf of the government, Minister Nanayakkara declared, in Kilinochchi, recently, that another anti-terrorism law would be placed before the people, within two months. According to the top law academic, what has been rejected was far worse than the PTA currently in use.

Sri Lanka first received–GSP-plus in July, 2005, but was revoked in 2010 over war crimes allegations. The EU granted the same in May, 2017.

Declaring that they were in the dark regarding the latest proposed law, the former parliamentarian said that an anti-terrorism law, compatible with international standards, couldn’t be produced without wider consultations among all interested parties.

Sri Lanka has ratified all 27 core international conventions on human rights, labour standards, environmental protection and good governance.

Prof. Peiris said that during his second tenure as the Foreign Minister, the then government tendered a written assurance to the Geneva-based United Nations Human Rights Council (UNHRC) that a new anti-terrorism law would be introduced.

Referring to four-member delegation of the United Nations Subcommittee on Prevention of Torture (SPT) visiting Sri Lanka from 15 to 24 June, 2024, Prof. Peiris emphasized the responsibility on the part of the government to adhere with universally accepted human rights norms.

At the onset of the briefing Prof. Peiris flayed the government over the way opposition activist Sugeeshwara Bandara had been arrested by police in Kollupitiya, very similar to operations directed at the underworld. Pointing out that the police also took into custody Binoy Hettiarachchi, a media coordinator at the Flower Road Office, Prof. Peiris alleged that the NPP government was suppressing political opposition.
