Is plastic recycling a myth?

Published

on

So, plastic recycling remains a myth, a catchphrase used by governments and industries, globally, to whitewash yet another tragic byproduct of industrialisation. The worst part of this mythmaking is that it puts the burden on the consumer, when there is very little they can do. The establishment touts three “Rs”: reduce, reuse, and recycle. They all have huge limitations under real life conditions.

Plastic recycling was the topic of several recent newspaper articles; they all stressed the obvious need for action. However, they have failed to mention several hidden realities pertaining to this subject, and the goal of this write-up is to draw attention to the other side of the story. There is no argument that plastic waste litters the beaches and reduce their appeal to the tourists, but it is more widespread than that: plastic is found in inaccessible places of the globe like the Mariyana trench, the Antarctic icecap, and the highest peaks of the Himalayas. Besides the visible pollution of the environment, plastic is found in most living organisms; the human body, breast milk and the placenta included. This has enormous health and evolutionary consequences, yet less than nine percent of the plastic used is recycled globally, leaving billions of tons of plastics to rot unmitigated, snowballing a problem that has epic consequences not unlike the climate change or nuclear war.

Cellulite, the first known plastic material, was introduced in 1862; this is a polymer of a naturally occurring cellulose. The first totally synthetic plastic Bakelite was produced in 1907. The shortage of natural rubber during World War II led to the manufacture of numerous plastics in vast quantities, and this trend continues with ever increasing demands and innovations. This industry has introduced a plethora of chemical entities that have never ever existed on planet earth before. Mother Nature is resilient, and she will deal with them in her own way. However, the potential consequences of such adjustments should not be taken lightly; the most long-lasting living beings on this planet, the dinosaurs that lived for 165 million years, could not adjust to the effects of dust and smoke generated by a meteor impact. Let us not forget that despite their unparalleled sophistication, sense of superiority and invincibility, modern humans have inhabited the earth only for 160 thousand years: a mere blip in the 4.5-billion-year history of the planet that could end up just being that if they do not heed reality.

The curse of plastics goes way beyond spoiling the beauty of a serene beach or a sacred, pristine mountain top. This has to do with the way plastics degrade, or the way they resist degradation, depending on if it is looked at macroscopic or microscopic level. Cellulose being a natural substance, it decomposes naturally. There are microbes that can chew them up and return them back to carbon dioxide and water for reuse by plants. Plastics being brand new, nature had not had a chance to develop a way to do the same, there are no enzymes that can chew up plastics. Therefore, they do not rust or rot the way metals and wood would do and disappear.

When plastics degrade, that is when they physically break up, they produce minute pieces known as microparticles. These can vary in size, but they are generally considered to be particles smaller than one hundred microns. For comparison, the diameter of a human hair typically ranges from about 50 to 70 microns. Because of this microscopic size, these particles can spread throughout the environment and penetrate many barriers including living tissues. They can enter the body through ingestion, inhalation, or contaminated food, water, and beverages. In fact, plastic microparticles have been found in almost all living organisms, particularly in marine life, and all human tissues.

One may ask if they are non-reactive, or inert, what harm could they do? First, since they do not degrade, they accumulate in the tissues, this is a significant problem for long living organisms. The second is a more complex reason: all enzymes, the proteins that carry out all biochemical reactions in living organisms, do so based on their shape, like the shape of a key is specific to the lock it can unlock. An enzyme assumes a specific shape to accommodate its substrate to carry out its biochemical conversion. When the products of enzymatic transformations build up, it changes the shape of the enzyme and stops the reaction. This is an important feedback mechanism that maintains the biochemical balance, or homeostasis of the body. The trouble is that some plastic microparticles can mimic these natural substances thereby changing the activity of enzymes and disturbing the natural balance.

A wide range of diseases are now known to be caused by plastic contamination: Auto-immune conditions, Birth defects, Cancer, Cardiovascular diseases, Chronic inflammation, Diabetes, Inflammatory bowel disease, Liver and kidney problems, Low birth weight, Neuro-degenerative diseases, Rheumatoid arthritis, Stroke, and Thyroid gland disruptions are some examples. Ironically, despite the improvements in living standards, and advances in medicine, these ailments are on the rise; there are no doubts about the obvious reasons.

Recycling is a catch phrase universally used whenever these issues are raised. Unfortunately, the same properties that make plastic so useful render their recycling equally difficult, if not impossible. Once plastic is melted, it loses some of the properties designed for a particular product, making it less suitable for the manufacture of the same product. For example, polythene bags can be turned into composite lumber or playground equipment, but not bags of the same quality. This and the logistical challenges involved in collecting, sorting, and preventing contamination makes recycling less practical and more expensive than using fresh plastic raw materials. Because of this inherent limitation, less than 9% of the plastics produced globally are truly recycled. Incineration is a much more dangerous practice, as it releases more dangerous toxins to the environment in addition to more microparticles.

So, plastic recycling remains a myth, a catchphrase used by governments and industries, globally, to whitewash yet another tragic byproduct of industrialization. The worst part of this mythmaking is that it puts the burden on the consumer, when there is very little they can do. The establishment touts three “Rs”: reduce, reuse, and recycle. They all have huge limitations under real life conditions.

The burden should be on industry, instead. They have a habit of creating problems in the name of progress and palming them off to consumers, particularly those in the developing world. Plastics are not alone, there are other examples: antibiotics, internal combustion engine, pesticides – DDT in particular, and nuclear fission are some, but there are many more. In the case of plastics, it is not for the lack of alternatives; the world functioned just fine before 1907. The four hundred metric tons of plastic produced annually will sit somewhere long after humans are gone, and until the sun turns into a red giant and gobbles up the earth. Sadly, in the current context, innovation means making more money, and not the betterment of the human condition. “Continue to contaminate your bed, and you will one night suffocate in your own waste,” Chief Seattle, the patriarch of a native American tribe, wrote to then US president in 1855, regarding the European occupiers’ lack of respect for nature. He warned that they too would pass – sooner than some other tribes. It is time humanity came to this realization.

Combining local resources,traditional knowledge and science to build a food-secure Sri Lanka

World Food Day 2026: Innovating today for a better food future

by Dr. Kaushalya Wijayasekara

What will be on the Sri Lankan dinner table ten years from now? Will our children be able to get nutritious food at a price their families can afford? Will farmers be able to grow enough despite changing weather and rising costs? And how much of the food we produce will actually reach the consumer, instead of being lost or wasted along the way?

These questions can’t wait. A farmer faces unpredictable weather. A family faces rising food costs. Fruit goes unsold after a good harvest. Some children do not get enough nutrition. The future of food is tied to the future of Sri Lanka itself.

World Food Day 2026 is a chance to look beyond the immediate problems and ask whether we can build a food system that feeds our people well, gives farmers better opportunities, protects the environment and makes better use of what we already have. The answer can be yes, but we will have to think differently.

We are not starting from zero. Sri Lanka has diverse crops, fisheries, traditional food knowledge, indigenous varieties, research institutions, universities and a young generation able to create new solutions. What we need is to bring these together and act. Producing more will not secure our food future on its own. It will depend on how intelligently we produce, process, preserve, distribute and consume food.

Making more of what we already have

Innovation does not always mean inventing something new. Often it means finding better uses for the resources we have.

Sri Lanka grows traditional rice varieties, kurakkan, green gram, cowpea, jackfruit, breadfruit, cassava, sweet potato, coconut and palmyrah. All of them have great potential for modern, nutritious, value-added foods. Jackfruit and breadfruit can be made into flour and other convenient products. Traditional rice varieties can go into new foods that suit changing consumer needs. Palmyrah, with its strong cultural heritage, can create new income through better processing, packaging, quality assurance and market development.

The aim is to connect our traditional food knowledge with modern consumer needs and technology, while keeping our food heritage.

Stop wasting the food we produce

Reducing food loss and waste should be a major priority. Seasonal fruits such as mango, banana, papaya and pineapple can be lost in large quantities when production exceeds demand or when storage, transport and processing facilities are inadequate. With suitable technology, these fruits can become dried products, pulps, powders, beverages and other shelf-stable foods.

Agricultural and fisheries by-products are resources too. They could be turned into food ingredients, animal feed, bio-based products and other useful materials, which would move us toward a more circular food economy.

Technology alone is not enough. We need stronger local processing facilities, cold storage, efficient transport, collection centres and market information systems, especially close to where food is produced. Cutting food loss raises the value of what our farmers and fishers already produce.

Nutrition and food safety come first

Food security means more than having enough food. People also need food that is safe and nutritious.

Sri Lanka can develop affordable, nutritious foods from local pulses, grains, vegetables, fruits and fish. Children and other vulnerable groups should get particular attention. Schoolchildren in particular deserve a focus: safe, nutritious, locally sourced products for school feeding programs would support child nutrition, local farmers and domestic food industries at the same time.

Food safety must stay at the centre of food innovation. Good hygiene, quality control, laboratory testing, traceability and appropriate food safety systems are what make new products safe as well as attractive and nutritious.

A food system that can cope with climate change

Climate change is already affecting agricultural production, water availability, crop yields and food prices. We need food systems that can handle changing conditions. That means climate-resilient crops, efficient water use, soil and water conservation, better storage and resource-efficient food processing.

Traditional knowledge matters here. Generations of Sri Lankan farmers have developed practices suited to local climates and ecosystems. Combining that experience with modern science can give us solutions that fit local conditions and are sustainable. Technology alone will not build the future of food. Science, experience and local knowledge together can.

Give young people a bigger role

Sri Lanka’s universities have an important part to play in shaping our food future. Young people should be encouraged to identify real problems in the food system and work on practical solutions in areas such as food waste, sustainable packaging, nutrition, food safety, modernising traditional foods and digital technologies.

A good research project should not always end as a research paper. Where appropriate, research should be supported to move on to products, technologies, enterprises and community solutions. That needs stronger partnerships between universities and industry, along with mentoring, research funding, business support and market connections. If young researchers and entrepreneurs can turn their ideas into viable food innovations, both consumers and producers will benefit.

A pathway designed for Sri Lanka

We do not need to copy food-system models from other countries. We can build a pathway that suits our own resources, culture and needs. It would bring together local resources, traditional knowledge, scientific research, appropriate technology and entrepreneurship, with farmers, fishers, universities, research institutions, food industries, entrepreneurs and policymakers working side by side.

The goal goes beyond selling raw materials. We need to create more value, reduce waste, improve nutrition, generate jobs and strengthen rural livelihoods. This matters especially for small and medium-scale food enterprises, which can drive local economic development when they get the right technical, financial and market support.

The choices we make today

The food future will not create itself. It will be shaped by what we grow, what we research, what we process, what we consume and what we choose not to waste.

So, the question for World Food Day 2026 is this: what can we do today so that every Sri Lankan has safe, nutritious, affordable and sustainable food tomorrow?

The answers are already around us, in our farms, fisheries, food businesses, universities, laboratories and communities. We have the resources, the traditional knowledge, the scientific expertise and talented young people. What we need now is to connect them and act.

A better food future begins with the choices we make today.

20th Anniversary of Digampathana blast – the day Sri Lanka Navy cried

Aftermath of the terror attack

The Digampathana suicide truck attack on 16th October 2006 remains the deadliest single strike in Sri Lanka Navy history, leaving scars that time cannot erase.

It was a seemingly ordinary Monday morning on 16 October 2006, but the calm of that day would soon be shattered in a way none of us could have imagined. As the Commandant of the Naval and Maritime Academy and Flag Officer Commanding Naval Fleet at Trincomalee, I was aware that a number of my cadets were travelling that morning, part of a convoy of fifteen buses carrying naval personnel from Trincomalee, Colombo, and other bases, heading toward Dambulla to rendezvous with another group. The convoy also included trucks and escort vehicles, a routine movement planned and coordinated with the army to ensure the roads were clear. The morning started quietly. Some personnel greeted friends, handed over their weapons, or strolled to a nearby tea shop. It all seemed so ordinary—too ordinary for what would come next.

Sri Lanka Navy sunk LTTE Ships carrying arms, ammunition and warlike materials thousand miles away from Sri Lanka in Indian Ocean in September and October 2007.

By late morning, both convoys had reached the small ground at Digampathana, near the Sigiriya junction, and personnel mingled briefly, unaware that a carefully orchestrated act of terror was waiting. Then, suddenly, an empty half-truck veered directly into the convoy. It exploded with a ferocity I can still recall as if it were yesterday. Nuts, bolts, and high explosives tore through the air. Pandemonium erupted instantly. I later learned that 107 of our naval personnel were killed on the spot and another 153 critically injured. The scene was indescribable—bodies scattered, vehicles mangled, personal effects strewn across the ground. I remember later hearing that the head of the suicide bomber was recovered more than 100 meters away from the blast, a grim testament to the sheer force of the explosion.

I was in my office at the Naval and Maritime Academy when my mobile phone rang. A young midshipman from the 21st intake called, his voice trembling: “Sir, there was a huge explosion at the convoy point! Many are dead … my batch mate Wijesundara is among them.” I immediately jumped into my jeep with my escort Chief Petty Officer and driver and rushed to Digampathana, relying on every ounce of my driving skill to reach the scene. The journey, which usually took little more than an hour, felt endless that day, each passing mile weighed down by dread.

When I arrived, I was confronted with a sight that no training can prepare you for. The injured were being rushed to Dambulla Hospital, where doctors and nurses worked tirelessly, improvising in ways that saved lives despite the overwhelming chaos. I went back to the site after visiting the hospital. The remains of our naval personnel were scattered across the ground, and someone had begun collecting weapons and protective gear. I immediately contacted Surgeon Rear Admiral Nico Jayasekara and received his instructions: collect all body parts in separate bags and transport them to the Trincomalee Naval Hospital mortuary. This gruesome work had to be done with care and dignity, and it filled the icebox in my vehicle. Through DNA testing initiated by Rear Admiral Nico, we were able to identify every naval personnel lost that day, bringing some closure to grieving families.

The Navy Commander at the time, Vice Admiral Wasantha Karannagoda, was devastated. I had worked closely with him and knew how deeply he cared for his men. He ensured that the fallen were honoured with full ceremonial naval funerals at Welisara Naval Base, attended by families and comrades. Sixty-seven funerals were conducted in a single day—a number that still haunts me.

The Digampathana attack remains the largest single loss of naval life in our history. It was a day of sorrow, but also a day that reinforced our resolve. The tragedy galvanized the Navy to target the LTTE Sea Tiger wing with renewed determination and reshaped our maritime operations forever. Every time I think of that day, I remember not just the lives lost, but the courage, professionalism, and dedication of those who survived, those who treated the injured, and those who ensured the fallen were honored properly. May the souls of our naval hero’s rest in peace, their sacrifice guiding us and inspiring generations of naval personnel to come.

‘Murder at Whitby Abbey’

Published

Tales of Mystery and Suspense – 24

I was intrigued by the title of a book I found in a book drop at the condominium of a friend, Murder at Whitby Abbey, and I brought it home with me though I will not be able to return it in the near future. It was described on the cover page as ‘a standout in the crowded medieval mystery field’, though I fear I do not know of other books in this field, apart from the Cadfael series, which I have dealt with earlier.

The book, by Cassandra Clark, is set during the reign of Richard II and has as a backdrop his precarious position, which led to his being replaced, and murdered, by his cousin Henry, who reigned as Henry IV. It is a gloomy book, the action taking place in the twelve days of Christmas leading up to the Epiphany. And the gloom is pervasive, even though this is supposed to be a time of festivity, with mummers performing, and many of those in the guest house where the heroine stays going to town to enjoy themselves, with much drinking and much music, which also fills the guesthouse.

The heroine Hildegarde is a nun, sent to try to acquire a relic being sold by Whitby Abbey, though this was also a penance set by the Abbot of the monastery that governed her abbess because she had had sex with a man. Soon after she and her companions reach the Abbey set high on a cliff, she finds that there are other bidders, and soon suspects that the hierarchy, not perhaps the Abbot who seems a weakling, but his rapacious bursar, is determined to make money, and not above creating false relics to sell to several aspirants.

After Hildegarde and her Cistercian companions – Whitby is a Benedictine Foundation – two monks, Gregory and Egbert, and a young priest Mark, reach the abbey, they find that Aelwyn, a monk they had met on their way to the guesthouse had died. This was in the apple store, and they realize, when they find the surplices of novices stuffed into the air vents, that he had been left to suffocate in the overwhelming scent of apples.

Clark

The Cistercians are asked to look into the death, perhaps because they are likely to get no cooperation from the Abbey folk, but perhaps because those in charge are keen to know what happened. And the infirmarer, an old monk, suggests Hildegarde talk to a man called Edred who worked for the bursar, and had been a friend of Aelwyn’s. But Edred too is killed, before he can keep an appointment he had made with Hildegarde, drowned in a pool near the farmhouse of the Abbey.

Meanwhile tensions arise between the fisherfolk and the abbey for the bursar wants to charge them for using the beach that technically belongs to the abbey to dry their fish and their nets. This leads to physical battles, when the guards used by the abbey, under the command it seems of the bursar whose determination to make money is not resisted by the abbot and the prior, try to storm the area where the fishermen live.

Hildegard finds out more about what had happened through two youngsters, one of whom Torold is the son of Aelwyn by a woman who worked as a prostitute for a cartel, and with whom Mark fell in love. The other works on the farm and had seen Edred meet someone near the pool, after which that someone left the place by himself. And the boy had also found in the pool a sort of dagger with the seal of the abbey.

He and his dog, and Torold who follows her, rescue Hildegarde from a man at arms who has waylaid her and tries to rape her earlier. Escaping into the abbey she was nearly been raped then by the bursar, but she managed to escape, in the process setting fire to him and the muniments room, which led, when he was rescued, to the discovery of a box with the money he said had been stolen, blame being cast on both Aelwyn and Edred.

Matters come to a head when the fisherfolk try to storm the abbey, being resisted by the men at arms stationed on the towers. But then Hildegarde realizes that behind the murders was the bursar’s clerk, whom she pursued to the cathedral. There is great drama then as she escapes from him when he tries to kill her, and then from the man at arms who had tried to both rape and kill her, but they both fall from the scaffolding she had climbed, the latter coming from a tower where he had been stationed.

Both of them think they run the rapacity of the abbey, the latter claiming to work for the nobles opposed to Richard, who is presented throughout the book as devoted to his subjects, not to power or money. But though the villains die, the bursar continues, having got over the hysteria the fire had caused and his acknowledgment then of guilt – and though the abbot and the prior seem less vicious, whether they will be able to assert themselves is questionable.

Before the climax, when the others in the guesthouse were leaving, Hildegarde found that two of them were in possession of the relic, for which they seem to have paid well. Hildegarde herself had made a derisory offer, but before she leaves the abbot gives her the relic, perhaps in gratitude for what she and her fellow Cistercians had discovered, the abbey having made as much money as it needed and more from the gullible other buyers.

Mark’s inamorata is saved from the stews because she moves in with Edred’s widow whom the bursar had thrown out of the rooms he occupied when her husband was found dead. Hildegarde had paid for lodgings, in a house run by the man who ran the brothels, but he had a kindly side and was going to finance them to make nets for the fishermen.

So, the Cistercians set off for their home as swiftly as they can to get there on the day of the Epiphany, having stopped en route to pray for King Richard whose birthday it was.
