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.

Why record export earnings may not be good news



By Gomi Senadhira

The press release by the Central Bank on the external sector performance ,in June 2022, perhaps was the first piece of good news we had received for a long time. According to the press release, “Earnings from merchandise exports, in June 2022, increased by 23.9 percent over the corresponding month, in 2021, recording US dollars 1,248 million, which is the highest ever monthly export earnings recorded. An increase in earnings of both industrial and agricultural exports contributed to this favourable outcome, …. Cumulative export earnings, from January to June 2022, also increased by 14.3 percent, over the same period in the last year, amounting to US dollars 6,514 million.” So, most of us would think we have enough dollars to cover our essential imports. But, apparently, that is not the case.

Earlier, the Central Bank Governor, Dr. Nandalal Weerasinghe, had said that exporters only converted about 20% of their export earnings into Sri Lankan Rupees and the rest was not brought back to Sri Lanka. That amounts to the US $800 million a month! The Governor had also said “… At least 40% of the total export earnings should be added to the formal financial system of the country. So exporters have a responsibility, at a very difficult time like this, to bring back their foreign exchange, through the banking system, and if that happens, then we can resolve the fuel crisis comfortably.”

(Diesel shipment that arrived in Colombo, on 16 July, still not paid for want of dollars – The Island July 30th) It appears as if the Governor is pleading with the exporters to bring back at least 40% of their export earnings. More notably, from Dr Weerasinghe’s statement, it is clear that the exporter had only converted 20% of their export earnings to rupees during the last five months. Did they convert their export earnings to rupees during the last year, or in the previous years? For how long has this been going on? When the Central Bank says “… exporters have a responsibility, at a very difficult time like this, to bring back their foreign exchange, through the banking system,” does that mean the foreign exchange earned, with the exports, is brought through the hawala network, or other similar arrangements?

Exporters deserve credit for the great service they provide and should be rewarded, appropriately. But not disproportionately. The export earnings are not earned by the exporters alone. These earnings are earned by all those who contribute to manufacturing the export products. All of them should be getting their fair share of the export proceeds. If not, there is something terribly wrong with the system. Is this normal in international trade?

During the last few years, some of the studies by Indian scholars, including Utsa Patnaik and Shashi Tharoor, have placed in the public domain some of the less known facts on the effects of the British colonial rule on India. They explain how the British seized India, “… one of the richest countries in the world – accounting for 27% of global GDP in 1700 – and, over 200 years of colonial rule, reduced it to one of the world’s poorest,” and how during the period British Raj siphoned out $45 trillion from India.

How was this done? Patnaik explains, “In the colonial era, most of India’s sizeable foreign exchange earnings went straight to London—severely hampering the country’s ability to import machinery and technology in order to embark on a modernisation path, similar to what Japan did in the 1870s. …, a third of India’s budgetary revenues was … set aside as ‘expenditure abroad’. The secretary of state (SoS) for India, based in London, invited foreign importers to deposit with him the payment (in gold and sterling) for their net imports from India, which disappeared into the SoS’s account in the Bank of England. Against these Indian earnings he issued bills… to an equivalent rupee value—which was paid out of the budget, from the part called ‘expenditure abroad’.” Patnaik underlines that this was “something you’d never find in any independent country,”

But it appears something very similar is happening in Sri Lanka, many years after the independence! If the exporters do not “bring back their foreign exchange ,through the banking system,” or only bring back 20% of it, then how do they pay for goods and services obtained locally? The local value addition for most of our exports is 70% to 80% or higher! The only major exception is cut and polished diamonds. Tea exporters buy tea with rupees. Some of the imported inputs, like fertiliser, or diesel, are sourced locally! The garment industry had moved up the value chain during the last 40 years and provide many value-added services, like designing, locally.

How do the exporters pay for all these goods and services, if they keep more than 60% of their export earnings outside the country? Do they get it through “hawala” or similar arrangements? During the British Raj, payments to local producers were done with the taxes collected by the Raj. In present-day Sri Lanka, how does one manage to raise a large amount of cash to operate such a system?

If a sizeable chunk of Sri Lanka’s foreign exchange earnings goes straight to banks in London, New York, Zurich, or elsewhere, severely hampering the country’s ability to import essential items, doesn’t that mean, Sri Lanka’s wealth is getting siphoned out through our exports? And there is not much of a difference between what happened during the colonial period and the post independent Sri Lanka!

So, June’s record export earnings also mean nearly US$ billion was siphoned off during the month! A new record for the month of June! And that means Patnaik was wrong when she said this was not “something you’d never find in any independent country”

That is not good news.

Improving trend needs to be sustained on multiple fronts



by Jehan Perera

The government appears to have secured political stability in the short term.  So far President Ranil Wickremesinghe’s efforts to restore stability appear to be working. Political stability is necessary for decisions to be made and kept.  It is a necessary element for international support to come in.  One of the IMF’s conditions to provide the country with the multi-billion-dollar loan it seeks is political stability that would ensure that commitments that are made will be kept.  The protest movement has not mobilised public demonstrations on the very large scale of the past after the appearance of Ranil Wickremesinghe in leadership positions, initially as prime minister and subsequently as president. This would be seen as an achievement by the government.  The present governmental line that protests should be within the law is difficult, and also frightening, to challenge when a state of emergency is in force.

The government has shown its ability to wield the emergency law with deterrent effect. Under the state of emergency that President Wickremesinghe declared on July 18, the period that a person may be detained before being brought before a magistrate has been increased from 24 to 72 hours. The authorities have been granted additional powers of search and arrest, and the military has been empowered to detain people for up to a day without disclosing their detention. The state of emergency also gives the president and the police broad powers to ban public gatherings, allows the police or military to order anyone to leave any public place or face arrest, and makes it an offense to cause “disaffection” or to spread “rumours.” However, in a sign that Sri Lanka’s system of checks and balances is still working, the Colombo Chief Magistrate’s Court has rejected a request by the police to ban a public protest planned by political parties and multiple organisations on September 9.

Human Rights watch has pointed out that “these provisions are vague, overly broad, and disproportionate in violation of the rights to freedom of expression, peaceful assembly, association, and movement.”  The midnight strike on the protestors who had camped for over three months at the main protest site at Galle Face would make any reasonable person think twice before getting into physical confrontation with the government.  The social media coverage of events that night showed men in black uniform and wearing masks, attacking the unarmed protestors.  As these men did not wear identification badges, there is a question whether they were part of the official security forces or drawn from other groups that work with them.  This response brought discredit to the perpetrators and disturbed both Sri Lankan people and the international community that have the welfare of Sri Lanka at heart.

The government has also used the full power of the draconian law to ensure that the leadership of the protest movement is neutralised. Several of them have been arrested, some of them given bail, others remanded, which would send a chilling message to the others.  The government has also shown its willingness to offer high positions to those who are prepared to join it.  This has led to a situation where two trade union leaders active in the protest movement have been treated very differently.  One has been offered a high post while the other has been put into prison, although he has now been given bail.  In a signal that he is sensitive to public pressure and human rights concerns, President Wickremesinghe had spoken to leader of the Ceylon Teachers Union, Joseph Stalin, after he was remanded and reportedly said he admires the members of the protest movement who talk of a system change.


Apart from the appearance of political stability there is also the appearance of economic stabilisation.  The shortages of cooking gas, petrol and diesel, and the 13-hour power cuts were among the main catalysts of the protest movement.  It was during the period of long power cuts, when staying at home became unbearable, that neigbourhood groups began to converge in urban centres to hold candlelight protests.  However, at this time the supply of gas, petrol and diesel has improved significantly and the kilomere-long lines in front of fuel stations are much less common.  Credit has gone to the QR code system put in place that gives to each vehicle a weekly quota.

The challenge for the government is to ensure that the economic situation continues to be stable without experiencing the acute shortages of key items that causes distress to the general population.  The QR code system can only work if there is petrol and diesel to be distributed.  The current imports of cooking gas, petrol and diesel appear to have been made possible by a World Bank loan which was re-purposed to the purchase of essential items.  However, these funds will dry up soon.  The question is what will happen after that.  There is apprehension that the country will fall once again into a situation of severe shortage.  The government needs to take the people into its confidence regarding the future.  The government also needs to be trusted if it is to be believed.

The World Bank has given an indication that they are still to be convinced regarding the provision of further assistance to Sri Lanka.  Earlier this month, the World Bank issued a statement “expressing deep concern about the dire economic situation and its impact on the people of Sri Lanka yesterday said it does not plan to offer new financing to Sri Lanka until an adequate macroeconomic policy framework is in place.  Issuing a statement, the World Bank Group said it is repurposing resources under existing loans in its portfolio to help alleviate severe shortages of essential items such as medicines, cooking gas, fertiliser, meals for school children and cash transfers for poor and vulnerable households.  To date, the World Bank has disbursed about US$160 million of these funds to meet urgent needs.”  This is extremely concerning as the World Bank is closely connected to the IMF on which Sri Lanka is pinning its hopes for a big loan.


The issue of political stability is highlighted by the government as being necessary to obtain international assistance and also as a justification for quelling the protest movement through emergency laws.  There is explicit blame being apportioned to the protest movement for creating instability in the polity that is deterring the influx of foreign assistance and investments.  However, the fuller picture needs to be seen.  The IMF as much as the World Bank, and indeed other potential sources of donor support, want their resources to be used for the intended purpose and not be squandered or siphoned away corrupt practices and in sustaining loss-making state institutions.

The hoped-for IMF-supported programme to provide assistance to Sri Lanka is being developed to restore macroeconomic stability and debt sustainability, while protecting the poor and vulnerable, safeguarding financial stability, and stepping up structural reforms to address corruption vulnerabilities and unlock the country’s growth potential. IMF mission team to Sri Lanka last month specifically mentioned the need to reduce corruption stating that “Other challenges that need addressing include containing rising levels of inflation, addressing the severe balance of payments pressures, reducing corruption vulnerabilities and embarking on growth-enhancing reforms.”

Both the international funding agencies and the protest movement are on the same page when it comes to opposing corrupt practices.  The main slogans of the protest movement during their heyday was the ouster of the then president, prime minister and cabinet of ministers, and indeed the entire parliament, on account of the corruption that they believed was responsible for having denuded the country of its foreign exchange reserves. This was not simply the replacement of one set of corrupt leaders by another. There are disturbing signs that some of those accused of corruption are once again on the ascendant.

The underlying demand of the protest movement was and continues to be the very “systems change” that the president has said he admires in his reported discussion with remanded trade union leader Joseph Stalin. Civil disobedience to obtain a government that is transparent and law abiding, that does not steal the wealth of the country, is a noble goal, no less sacred than the civil disobedience struggles engaged in by Mahatma Gandhi in India and Martin Luther King in the United States.  The ingredients for a rebound of the protest movement continue to be in place and hopefully the evidence of a systems change will become more convincing.

Brenda Mendis… ‘Gindara Kellek’



I first got to know Brenda Mendis when she was very much a part of the group Aquarius, before joining Mirage..

With Aquarius, her dynamism bloomed, on stage, when she partnered two other female vocalists – from the Philippines.

And…yes, they certainly did rock the scene; the three girls were the talk-of the-town and they were featured at some of the best venues in the city.

She was also, at one time, associated with the band 2Forty2.

Brenda now operates with an outfit called C Plus Band, and with whatever free time, that comes her way, the talented artiste is now working on originals.

The latest is the song ‘Gindara Kellek’ and this is what Brenda has to say:

“I have known this guy Chathurangana de Silva for a very time and he has been involved in composing certain songs for the C Plus Band.

“We then got down to discussing about putting together a song which could be classified as a fast genre in music, and Chathurangana, along with Sampath Fernandopulle, came up with the suggestion for the lyrics, and they did so, based upon a proper observation of my lifestyle and the personality portrayal of myself, and that’s how “Gindara Kellek’ came into the scene.”

Brenda went on to say that the composing was done during a tight schedule.

“As I am the female vocalist, on a full time basis, with the C Plus Band, it took us more time than what is usual spent at a recording session, because of our public performances.”

‘Gindara Kellek’ is not Brenda’s maiden effort. She has been involved in quite a few other originals, including ‘Tharu Peedena Seethale,’ ‘Obai Mage Thaththe,’ ‘Mage Raththaran,’ ‘Kaprinna (Chooty),’ ‘You Never Know,’ ‘Mea Nilwan Nimnaye, and ‘Sitha Igilee Gihin.’ And, they are all uniquely different to each other, she says.

With the country going through a tough period, Brenda, spends her free time working out and reading.

“I would take this opportunity, through your very popular music page, to thank all those who helped me throughout my journey in this wonderful field of music.

“I shall continue to keep music lovers happy, with my music, and I would also thank my followers for supporting me and for being with me throughout my career in showbiz.”
