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

World Environment Day marked by National Celebration under President’s Patronage
The National commemoration of World Environment Day 2026, held under the theme “Let us take action to mitigate the impacts of climate change”, was held this morning (05) at the Temple Trees under the patronage of President Anura Kumara Dissanayake.
The environmental policy of the present Government, which is guided by a vision of a sustainable environment that ensures the survival and well-being of all living beings, prioritises maintaining a balance between socio-economic development and environmental protection, with a view to fostering a healthy society and a balanced ecosystem. Accordingly, within the framework of sustainable development and in line with the principles of the United Nations Framework Convention on Climate Change, Sri Lanka is actively contributing to global efforts to reduce greenhouse gas emissions.
In line with this programme, a “Climate Week” was declared from 30 May to 05 June in conjunction with the 2026 World Environment Day National commemoration. A series of environmental programmes were organised across the country with the participation of the “Clean Sri Lanka” initiative and contributions from the public sector, private sector and civil society organisations.
Furthermore, in conjunction with this year’s World Environment Day commemoration, five forests, Ritigala, Aliyawetunuwewa, Mulagala, Konkatiyawa and Kallanchiya were declared reserved forests by the Department of Forest Conservation under the patronage of the President.
The introduction of the enhanced National Green Reporting Guidelines, the declaration of the Magama Sand Dunes as a sensitive area by the Department of Coastal Conservation and Coastal Resources Management, the clearance of the Elephant crossings by the Department of Wildlife Conservation and the designation of the Kuda Bubula Spring and Kapurella Hot Water Wetland as protected areas were also announced.
In addition, the first issue of the environmental magazine “Soba” for 2026, the “Soba Ketha” environmental publication and a resource book on plastic waste management were officially launched.
A certificate confirming that the World Environment Day national commemoration had been conducted as a carbon-neutral programme was also formally presented to the President.
The President also participated in the presentation of prizes and certificates to the winners of the art competition organised by the Climate Change Division, as well as to the winners of the eco-friendly innovations and designs competition organised by the Central Environmental Authority under the World Environment Day theme.
President Anura Kumara Dissanayake also joined a group photograph with environmental researchers.
Addressing the event, Minister of Environment, Dr. Dammika Patabendi stated that…
The United Nations designated World Environment Day in 1972. Today marks the second World Environment Day being commemorated under the National People’s Power Government. In collaboration with the Department of Forest Conservation, five forests have been declared as protected areas in conjunction with this year’s World Environment Day under the “Vanaspati” programme. These include Ritigala, Aliyawetunuwewa, Mulagala Reserve, Konkatiyawa Reserve and Kallanchiya five forests located in the Anuradhapura District. The Government began designating protected areas from World Environment Day 2025, when Nilgala, Kottawa, Thulhiri Kanda, Weerawila and Udaliyadda forests were declared as reserves.
The “Vanaspati” programme was officially launched on 15 June last year. Through this initiative, the Ministry of Environment and the Department of Forest Conservation successfully declared 29 forests as protected areas in 2025. In 2026, a further 50 reserves were declared on World Forest Day, focusing primarily on four districts including Ampara, Nuwara Eliya and Badulla. In addition, two more forests were declared protected in conjunction with the recent ‘Ehi Passiko’ Peace Walk. With today’s declaration of five additional forests, a total of 86 forests have been declared as protected areas within one year, which is a significant achievement.
We have made significant efforts to address human–elephant conflict. One of our key aspirations has been to create designated corridors that allow elephants to move safely through their natural habitats. Today, we have succeeded in opening three elephant corridors in the Hambantota and Monaragala districts. In addition to this, substantial work has been undertaken in recent years to establish elephant management reserves and facilitate the opening of such corridors. Although an elephant management reserve was declared in Hambantota several years ago, the necessary legal regulations and operational mechanisms had not been put in place. We have now gazetted the required regulations and appointed an operational committee and implementation work is currently underway. During this process, we identified shortages in human and physical resources within institutions such as the Department of Wildlife Conservation and the Department of Forest Conservation. As a solution, we have taken steps to fill existing vacancie.
Furthermore, arrangements have been made to strengthen institutional capacity by providing essential infrastructure, including the procurement of motorcycles, tractors, mini-tractors, and cab vehicles to support field operations and improve efficiency.
We are currently working on formulating a policy for the management of tame elephants. In addition, efforts are underway to develop the Pinnawala Elephant Orphanage into an elephant breeding and research centre, addressing a key gap in the country’s conservation infrastructure. In the context of environmental protection, it is evident that many of the existing laws and regulations are outdated. Accordingly, steps are being taken to amend and modernise these legal frameworks.
Deputy Minister of Environment ,Anton Jayakody, Acting Secretary of the Ministry of Environment , R.H.M.P. Abeykoon, Chairman of the Central Environmental Authority , Professor Thilak Hewawasam, Director General of the Department of Wildlife Conservation S.M.L.R.P. Marasinghe, along with environmentalists, researchers, university and school students, were among those present on the occasion.

Elders’ home devastated by fire was a ‘house of horror’: Witnesses
Death toll rises to 12: Director remanded
Some residents were allegedly chained
Police have come under public pressure to investigate allegations of inhumane treatmenf the residents at an elders’ home in Batagoda, which was also reportedly used as a care centre for persons with special needs, following a devastating fire that has so far claimed 12 lives.
Eyewitnesses who were among the first responders told the media that several residents had been chained inside rooms at the Senehase Kedella Elders’ Home when the fire broke out on Wednesday. They claimed that rescue efforts were hindered as iron chains could not be removed, and that some residents died while being restrained.
Authorities have not yet verified these claims, and Police said investigations are continuing.
Police spokesman ASP F.U. Wootler, contacted for comment, said there were rumours to that effect, but the Police were not in a position to verify the claims until a report from the Government Analyst was received. He said eight survivors with burn injuries were being treated in hospital.
Meanwhile, the Director of the facility had been arrested and was due to be produced before the Horana Magistrate’s Court, Police said adding that he was remanded till June 11.
The death toll from the fire has risen to 12 as of Thursday morning following the recovery of additional charred remains during ongoing forensic examinations at the site. Six others sustained serious injuries and are being treated at the Horana Base Hospital.
Police said 72 residents were inside the facility at the time of the blaze. Of them, 10 died inside the building, seven were injured and hospitalised, while 51 were rescued and relocated.
Survivors were initially housed at Batagoda Junior School before being transferred with Army assistance to another branch of the same care network in Galpatha.
A magisterial inquiry was conducted on Thursday morning. Horana Magistrate Lakmini Vidanagamage visited the scene. The burnt remains were examined and removed under judicial supervision.
Separately, allegations have emerged that residents were required to pay an admission fee of Rs. 75,000, along with a monthly charge of Rs. 35,000 to the centre. Police have not commented on these claims.
The director was taken to the scene as part of ongoing investigations, while forensic experts continue examinations to determine the cause of the fire, which remains undetermined.Anguruwatota Police are conducting investigations.
