POLIPTO: AUTOPSY OF AN INCREDIBLE CLAIM
Dr U. Pethiyagoda.
Friends have wondered about my uncharacteristic interest in the claim made as far back as February 10/ 2009 (yes, eleven and more long years ago), that waste plastics, principally low gauge shopping bags (sili sili bags) could be economically converted to a diesel-type product. It is useful to record portions of what now seem like a tissue of untruths.
The spectacular claims (on record) included:-
(1) This was a World first, involving a unique “catalyst” discovered locally.
(2) The discoverer was not a formal chemist but a self-inspired retired Police Officer.
(3) The process was chemico-industrially endorsed by the academics of Moratuwa University.
(4) The Ministry of Environment and the Central Environmental Authority, assumed sponsorship.
(5) A commercial entity “Polipto” was established with 60% capital from the State, 30 % from CEA and 10% from Moratuwa University.
(6) Some Rs 6 million was proposed as initial expenses, later supplemented by Rs 25 million more from the Treasury
Meanwhile, the process was claimed to be energy-productive, the yield was 800 ml diesel-like fuel per 1.0 kg of polythene. The fuel was of combustible quality, such that it was claimed that the “Inventor” ran his (unmodified) car on the raw fuel with no ill effects! Shades “Dhammika Peni?” The secret “catalyst” is safely stored in the Vice-Chancellor’s custody at Moratuwa University. (It is regrettably not on record that it has been recently tested for efficacy). One prays that it is still active – otherwise all else will be lost. Meanwhile, a Production Unit has been set up and said to be in operation at Yatiyantota. The Inventor was hired as a well-paid Consultant. It is rumoured (never revealed for some obscure reason) to have cost (some) Rs 70 million.
It is the performance of this Unit that has found recent mention in Parliament. Interestingly, as far back as April 2010, just prior to some Election, Mr Champika Ranawaka (Minister of Environment at that time?) was actually pictured in the newspapers, feeding “Polipto” Diesel into Three-wheelers (free) from a commercial petrol pump! Could he too have been as deceived then, as all of us certainly were?
When this claim for indigenous Science first reached the Press, I had to be cautiously exhilarated. Cautiously, because I was aware that intense research interest has been drawn to similar procedures elsewhere because of their obvious and spectacular value. Our process was special because it promised a positive energy (and therefore commercial) value – which no other process had. On the basis of my rudimentary chemistry, the claim seemed to be in conflict with the very fundamental Law of the Conservation of Energy, that I had learned to appreciate. Here is an energy expending process converting hydrocarbon (crude oil?) to plastic and this being reversed to hydrocarbon with a net gain of Energy. Can’t be, it seemed to my simple mind! No colleague has yet been able to relieve my mind of this doubt. The age of Alchemy, which hoped to transform base elements to Gold is long gone.
“Polymerization” is one of the most versatile, useful and spectacular chemical phenomena in nature. Plastics (Polymers) provide great innovativeness and complexity of chemical designing talent. The variety that Industrial Chemical ingenuity has brought into our life through polymers, is staggering. Correspondingly, handling of a variety of compositions, are structures and configurations have to be complex. Hence there is a need for great and appropriate humility when claims for chemical reversal are made. To understand one’s limitations is not an inferiority complex. To believe that such a tangled chemical web can be unraveled by something akin to a “kema” has to look like wishful hope!
The local claims were wildly extravagant. They envisaged a diesel-like distillate which could be directly combusted in existing motor engines and yielding a national saving of two thousand million rupees (Rs 2,000,000,000/=) each year. It would have been kind to dismiss this as the occasional Hogwash/Bullshit. But, let it be remembered that this was implicitly endorsed by the University of Moratuwa and the Central Environmental Authority. Will they even now have the dignity and stature to admit to a serious error of judgment? Or, would they prefer it to be more honestly recorded as deceit or fraud?
That Industrial Chemists, equipped with respectable University qualifications, could be so naïve is astonishing. The reputation of an esteemed University has been sullied. Enormous expenditure (as yet obstinately undisclosed) has been incurred, an industrial (pilot) plant of unrevealed utility has been established at Yatiyantota – ancillary commitments are unknown.
Meanwhile, an interesting question has been asked by Mr. Udaya Gammanpila (UG) regarding “Polipto” and answered by Mr Chandima Weerakkody (CW), Minister of Petroleum in Parliament on May 18, 2016 (Hansard, p154 – 156) . For his response, the Minister has been poorly briefed – with an answer designed to confuse, conceal and obscure. UG, at the time of the happenings (which he now innocently questions!), was both Chairman of CEA (sponsors) and “Polipto” (executors). The grand full page pretext of (very appropriately April 1) 2010 showing Minister Ranawake pumping “Polipto” diesel into three- wheelers was most probably orchestrated by UG or his acolytes themselves! Only the public was deceived. Curiously, the questioner MP was Chairman of CEA at the time. His interest this matter is natural and commendable.
The pretext now of the product being “furnace fuel” is fraudulent. This conflicts with the earlier claim was that the distillate had run the inventor’s car successfully without need for any modification. This scoffs at the need for petroleum companies to engage in expensive, sophisticated research to design additives to enhance the performance of traditionally produced auto- fuel. In fact it insults them! So, “Polipto diesel” has now become furnace fuel – could it eventually go full cycle and end up as molten plastic? No surprise if it does!
To focus on just one point of CW’s answer in Parliament:- the plant is said to produce 800 litres daily, which will increase to 2,000 litres in a few weeks. With all this, it is only now that negotiations are being held on sale arrangements with the Ceylon Electricity Board! Will the private sector ever venture into a production process like that?
An earlier assertion was that 1 kg of shopping bags yields 800 ml of fuel (itself a dubious claim). If so, 2,500kg (2.5 tons) of “bags equivalent” is needed daily to yield 1,000 Litres. Can one visualize this bulk of bags and imagine its daily collection from the vicinity of Yatiyantota? Indeed, how does this quantity match up with the total annual production of polythene bags in the whole country? There is no evidence of systematic collection anywhere!
What of the daily collection costs? These and other realities cannot be airily dismissed. Energy costs at plant? Labour? Containers? Transport? Other consumables? And finally, product cost per litre? Remember that we were earlier promised “Polipto Petrol” at Rs75 to 80 per litre!
I have tried very hard to extract relevant cost data. I have encountered only stubborn silence, obstruction and where possible insult! It is only right that I now name names, distasteful though I find it.
Both Champika Ranawake and Tissa Vitarana have been given ample opportunity to provide details but have haughtily disdained. Wimaladharma Abeywickrema and his side-kick Roshan Gunawardene have dodged, insulted and been untruthful. Udaya Gammanpila has been duplicitious and Charitha Herath have all ignored legitimate requests for cost data. It is a pity that such an important scientific claim has only led to concealment. However, the greatest guilt in my book, has to pass to the University of Moratuwa staff who have sold their scientific integrity, and forsaken the reputation of their Institution – for what I do not know. They at least have exploited the non-sophistication of the purported inventor, Mr.Withanage.
If the rest of the scientific world had taken our claim seriously, there would be plentiful egg on several faces.
Even now, if my doubts and reservations are proven to be wrong I shall be grateful to be shown so. But the strongest proof would be the demonstration that waste polythene can be economically converted to a fuel combustible in an internal combustion engine. Then, all concerned will have my humble, sincere, abject and unqualified apology. Alternatively, let us be told candidly, that we were taken for a ride that stopped short of its destination. And, if possible – “WE ARE SORRY AND PROMISE NOT TO DO THIS AGAIN”. What, one wonders would be the fate of “Polipto”? If humble enough to accept a suggestion, by all means eliminate discarded polythene from the environment, melt and remold it into utility items where aesthetic excellence is not over-important. There will be a market.
Since I composed this essay, I chanced on a TV documentary which featured an enterprise for recycling empty water bottles (PET) into household brush-ware (brooms, brushes etc). This was commendable, organized use of a waste product – the way to go.

Relief without recovery
The escalating conflict in the Middle East is of such magnitude, with loss of life, destruction of cities, and global energy shortages, that it is diverting attention worldwide and in Sri Lanka, from other serious problems. Barely four months ago Sri Lanka experienced a cyclone of epic proportions that caused torrential rains, accompanied by floods and landslides. The immediate displacement exceeded one million people, though the number of deaths was about 640, with around 200 others reported missing. The visual images of entire towns and villages being inundated, with some swept away by floodwaters, evoked an overwhelming humanitarian response from the general population.
When the crisis of displacement was at its height there was a concerted public response. People set up emergency kitchens and volunteer clean up teams fanned out to make flooded homes inhabitable again. Religious institutions, civil society organisations and local communities worked together to assist the displaced. For a brief period the country witnessed a powerful demonstration of social solidarity. The scale of the devastation prompted the government to offer generous aid packages. These included assistance for the rebuilding of damaged houses, support for building new houses, grants for clean up operations and rent payments to displaced families. Welfare centres were also set up for those unable to find temporary housing.
The government also appointed a Presidential Task Force to lead post-cyclone rebuilding efforts. The mandate of the Task Force is to coordinate post-disaster response mechanisms, streamline institutional efforts and ensure the effective implementation of rebuilding programmes in the aftermath of the cyclone. The body comprises a high-level team, led by the Prime Minister, and including cabinet ministers, deputy ministers, provincial-level officials, senior public servants, representing key state institutions, and civil society representatives. It was envisaged that the Task Force would function as the central coordinating authority, working with government agencies and other stakeholders to accelerate recovery initiatives and restore essential services in affected regions.
Demotivated Service
However, four months later a visit to one of the worst of the cyclone affected areas to meet with affected families from five villages revealed that they remained stranded and in a state of limbo. Most of these people had suffered terribly from the cyclone. Some had lost their homes. A few had lost family members. Many had been informed that the land on which they lived had become unsafe and that they would need to relocate. Most of them had received the promised money for clean up and some had received rent payments for two months. However, little had happened beyond this. The longer term process of rebuilding houses, securing land and restoring livelihoods has barely begun. As a result, families who had already endured the trauma of disaster, now face prolonged uncertainty about their future. It seems that once again the promises made by the political leadership has not reached the ground.
A government officer explained that the public service was highly demotivated. According to him, many officials felt that they had too much work piled upon them with too little resources to do much about it. They also believed that they were underpaid for the work they were expected to carry out. In fact, there had even been a call by public officials specially assigned to cyclone relief work to go on strike due to complaints about their conditions of work. This government official appreciated the government leadership’s commitment to non corruption. But he noted the irony that this had also contributed to a demotivation of the public service. This was on the unjustifiable basis that approving and implementing projects more quickly requires an incentive system.
Whether or not this explanation fully captures the situation, it points to an issue that the government needs to address. Disaster recovery requires a proactive public administration. Officials need to reach out to affected communities, provide clear information and help them navigate the complex procedures required to access assistance. At the consultation with cyclone victims this was precisely the concern that people raised. They said that government officers were not proactive in reaching out to them. Many felt they had little engagement with the state and that the government officers did not come to them. This suggests that the government system at the community level could be supported by non-governmental organisations that have the capacity and experience of working with communities at the grassroots.
In situations such as this the government needs to think about ways of motivating public officials to do more rather than less. It needs to identify legitimate incentives that reward initiative and performance. These could include special allowances for those working in disaster affected areas, recognition and promotion for officers who successfully complete relief and reconstruction work, and the provision of additional staff and logistical support so that the workload is manageable. Clear targets and deadlines, with support from the non-governmental sector, can also encourage officials to act more proactively. When government officers feel supported and recognised for the extra effort required, they are more likely to engage actively with affected communities and ensure that assistance reaches those who need it most.
Political Solutions
Under the prevailing circumstances, however, the cyclone victims do not know what to do. The government needs to act on this without further delay. Government policy states that families can receive financial assistance of up to Rs 5 million to build new houses if they have identified the land on which they wish to build. But there is little freehold land available in many of the affected areas. As a result, people cannot show government officials the land they plan to buy and, therefore, cannot access the government’s promised funds. The government needs to address this issue by providing a list of available places for resettlement, both within and outside the area they live in. However, another finding at the meeting was that many cyclone victims whose lands have been declared unsafe do not wish to leave them. Even those who have been told that their land is unstable feel more comfortable remaining where they have lived for many years. Relocating to an unfamiliar area is not an easy decision.
Another problem the victims face is the difficulty of obtaining the documents necessary to receive compensation. Families with missing members cannot prove that their loved ones are no longer alive. Without official confirmation they cannot access property rights or benefits that would normally pass to surviving family members. These are problems that Sri Lanka has faced before in the context of the three decade long internal war. It has set up new legal mechanisms such as the provision of certificates of absence validated by the Office on Missing Persons (OMP) in place of death certificates when individuals remain missing for long periods. The government also needs to be sensitive to the fact that people who are farmers cannot be settled anywhere. Farming is not possible in every location. Access to suitable land and water is essential if farmers are to rebuild their livelihoods. Relocation programmes that fail to take these realities into account risk creating new psychological and economic hardships.
The message from the consultation with cyclone victims is that the government needs to talk more and engage more directly with affected communities. At the same time the political leadership at the highest levels need to resolve the problems that government officers on the ground cannot solve. Issues relating to land availability, legal documentation and livelihood restoration require policy decisions at higher levels. The challenge to the government to address these issues in the context of the Iran war and possible global catastrophe will require a special commitment. Demonstrating that Sri Lanka is a society that considers the wellbeing of all its citizens to be a priority will require not only financial assistance but also a motivated public service and proactive political leadership that reaches out to those still waiting to rebuild their lives.

Supporting Victims: The missing link in combating ragging
A recent panel discussion at the University of Peradeniya examined the implications of the Supreme Court’s judgement on ragging, in which the Court recognised that preventing ragging requires not only criminal penalties imposed after an incident occurs but also systems and processes within universities that enable victims to speak up and receive support. Bringing together perspectives from law, university administration, psychology and students, the discussion sought to understand why ragging continues to persist in Sri Lankan universities despite the existence of legal prohibitions. While the discussion covered legal and institutional dimensions, one theme emerged clearly: addressing ragging requires more than laws and disciplinary rules. It requires institutions that are capable of supporting victims.
Sri Lanka enacted the Prohibition of Ragging and Other Forms of Violence in Educational Institutions Act No. 20 of 1998 following several tragic incidents in universities, during the 1990s. Among the most widely remembered is the death of engineering student S. Varapragash at the University of Peradeniya in 1997. Incidents such as this shocked the country and revealed the consequences of allowing violent forms of student hierarchy to persist. The 1998 Act marked an important legal intervention by recognising ragging as a criminal offence. The law introduced severe penalties for individuals found guilty of engaging in ragging or other forms of violence in educational institutions, including fines and imprisonment.
Despite the existence of this law for nearly three decades, prosecutions under the Act have been extremely rare. Incidents continue to surface across universities although most are not reported. The incidents that do reach university administrations are dealt with internally through disciplinary procedures rather than through the criminal justice system. This suggests that the problem does not lie solely in the absence of legal provisions but also in the ability of victims to come forward and pursue complaints.
The tragic reminders; the cases of Varapragash and Pasindu Hirushan
Varapragash, a first-year engineering student at the University of Peradeniya, was forced by senior students to perform extreme physical exercises as part of ragging, resulting in severe internal injuries and acute renal failure that ultimately led to his death. In 2022, the courts upheld the conviction of one of the perpetrators for abduction and murder. The case illustrates not only the brutality of ragging but also how long and difficult the path to justice can be for victims and their families. Even when victims speak about their experiences, they may not always disclose the full extent of what they have endured. In the case of Varapragash, the judgement records that the victim told his father that he was asked to do dips and sit-ups. Varapragash’s father had testified that it appeared his son was not revealing the exact details of what he had to endure due to shame.
More than two decades after the death of Varapragash, the tragedy of ragging continues. The 2025 Supreme Court judgement arose from the case of Pasindu Hirushan, a 21-year-old student of the University of Sri Jayewardenepura, who sustained devastating head injuries at a fresher’s party, in March 2020, after a tyre sent down the stairs by senior students struck him. He became immobile, was placed on life support, and returned home only months later. If the Varapragash case exposed the deadly consequences of ragging in the 1990s, the Pasindu Hirushan case demonstrates that universities are still failing to prevent serious violence, decades after the enactment of the 1998 Act. It was against this background of continuing institutional failure that the Supreme Court issued its Orders of Court in 2025. Among the key mechanisms emphasised by the judgement is the establishment of Victim Support Committees within universities.
Why do victims need support?
Ragging in universities can take many forms, including verbal humiliation, physical abuse, emotional intimidation and, in some instances, sexual harassment. While all forms of ragging can have serious consequences, incidents involving sexual harassment often present additional barriers for victims who wish to come forward. Victims may hesitate to complain due to weak institutional mechanisms, fear of retaliation, or uncertainty about whether their experiences will be taken seriously. In many cases, those who speak out are confronted with questions that shift attention away from the alleged misconduct and onto their own behaviour: why did s/he continue the conversation?; why did s/he not simply disengage, if the harassment occurred as claimed?; why did s/he remain in the environment?; or did his/her actions somehow encourage the accused’s behaviour? Such responses illustrate how easily victims can be subjected to a second layer of scrutiny when they attempt to report incidents. When individuals anticipate disbelief, minimisation or blame, silence may appear safer than disclosure. In such circumstances, the presence of a trusted institutional body, capable of providing guidance, protection and support, become critically important, highlighting the need for effective Victim Support Committees within universities.
What Victim Support Committees must do
As expected by the Supreme Court, an effective Victim Support Committee should function as a trusted institutional mechanism that places the safety and dignity of victims at the centre of its work. The committee must provide a safe and confidential point of contact through which victims can report incidents of ragging without fear of intimidation or retaliation. It should assist victims in understanding and pursuing available complaint procedures, while also ensuring their immediate protection where there is a risk of continued harassment. Recognising the psychological harm ragging may cause, the committee should facilitate access to counselling and emotional support services. At a practical level, it should also help victims document incidents, record statements, and preserve evidence that may be necessary for disciplinary or legal proceedings. The committee must coordinate with university authorities to ensure that complaints are addressed promptly and responsibly, while maintaining strict confidentiality to protect the identity and well-being of those who come forward. Beyond responding to individual cases, Victim Support Committees should also contribute to broader awareness and prevention efforts, within universities, helping to create an environment where ragging is actively discouraged and students feel safe to report incidents. Without such support, the process of pursuing justice can become overwhelming for individuals who are already dealing with the emotional impact of abuse.
Making Victim Support Committees work
According to the Orders of Court, these committees should include representatives from the academic and non-academic staff, a qualified counsellor and/or clinical psychologist, an independent person, from outside the institution, with experience in law enforcement, health, or social services, and not more than three final-year students, with unblemished academic and disciplinary records, appointed for fixed terms. Further, universities must ensure that committees consist of individuals who possess both expertise and genuine commitment in areas such as student welfare, psychology, gender studies, human rights and law enforcement, in line with the spirit of the Supreme Court’s directions, rather than consisting largely of ex officio positions. If treated as routine administrative positions, rather than responsibilities requiring specialised knowledge, sensitivity and empathy, these committees risk becoming symbolic rather than functional.
Greater transparency in the appointment process could strengthen the credibility of these committees. Universities could invite expressions of interest from individuals with relevant expertise and demonstrated commitment to supporting victims. Such an approach would help ensure that the committees benefit from the knowledge and dedication of those best equipped to fulfil this role.
The Supreme Court judgement also introduces an important safeguard by giving the University Grants Commission (UGC) the authority to appoint members to university-level Victim Support Committees. If exercised with integrity, this provision could help ensure that these committees operate with greater independence. It may also help address a challenge that sometimes arises within institutions, where individuals, with relevant expertise, or strong commitment to addressing issues, such as violence, harassment or student welfare, may not always be included in institutional mechanisms due to internal administrative preferences. External oversight by the UGC could, therefore, create opportunities for such individuals to contribute meaningfully to Victim Support Committees and strengthen their effectiveness.
Ultimately, the success of the recent judgement will depend not only on the directives it issued, the number of committees universities establish, or the number of meetings they convene, or other box-checking exercises, but on how sincerely those directives are implemented and the trust these committees inspire among students and staff. Laws can prohibit ragging, but they cannot by themselves create environments in which victims feel safe to speak. That responsibility lies with institutions. When universities create systems that listen to victims, support them and treat their experiences with seriousness, universities will become places where dignity and learning can coexist.

Big scene … in the Seychelles
Several of our artistes do venture out on foreign assignments but, I’m told, most of their performances are mainly for the Sri Lankans based abroad.
However, the group Mirage is doing it differently and they are now in great demand in the Seychelles.
Guests patronising the Lo Brizan pub/restaurant, Niva Labriz Resort, in the Seychelles, is made up of a wide variety of nationalities, including Russians, Chinese, French and Germans, and they all enjoy the music dished out by Mirage, and that is precisely why they are off to the Seychelles … for the fifth time!
The band is scheduled to leave this month and will be back after three weeks, but their journey to the Seychelles will continue, with two more assignments lined up for 2026.
In August it’s a four-week contract, and in December another four-week contract that will take in the festive celebrations … Christmas and the New Year.

Donald’s birthday
celebrations
According to reports coming my way, it is a happening scene at the Lo Brizan pub/restaurant, Niva Labriz Resort, whenever Mirage is featured, and the band has even adjusted its repertoire to include local and African songs.
They work three hours per day and six days per week at the Lo Brizan pub/restaurant.

Donald Pieries:
Leader, vocalist,
drummer
Led by vocalist and drummer Donald Pieries, many say it is his
musical talents and leadership that have contributed to the band’s success.
Donald, who celebrated his birthday on 07 March, at the Irish Pub, has been with the group through various lineup changes and is known for his strong vocals.
He leads a very talented and versatile line up, with Sudham (bass/vocals), Gayan (lead guitar/vocals), Danu (female vocalist) and Toosha (keyboards/vocals).
Mirage performs regularly at venues like the Irish Pub in Colombo and also at Food Harbour, Port City.
