A bright future to our nation by developing process industry to its peak
The process industries, such as the chemical process industry, pulp and paper, food, pharmaceutical, and others, are vital to the economy of any country. It is important for a country to be able to convert raw materials into valuable and useful products rather than relying on imports in order to be a strong nation. Developed countries often have large-scale process plants that turn their natural resources into commercial realities.
Sri Lanka has had well-established process industries in the past, including a urea production facility at Sapugaskanda, a sulfuric production plant at Ranala, and a paper production plant at Embilipitiya. These industries contributed significantly to the country's GDP and saved a lot of foreign exchange by producing many of the essential industrial raw materials within the country. However, most of these large-scale production facilities, including the urea and sulfuric plants, have been closed down due to various reasons, such as environmental issues, lack of research and development, inadequate technological input, and poor maintenance.
The process industry in Sri Lanka today has not been able to meet the needs of the people. Despite having raw materials, production facilities, and a skilled workforce, the country still imports paper from other countries. Sri Lanka has the potential to produce sulfur as an intermediate product of petroleum refining and has abundant oxygen in the atmosphere, but still imports sulfuric acid from other countries. The production of ammonia and sulfuric acid is essential for the manufacture of fertilizers, and it would save a significant amount of foreign exchange and reduce the cost of fertilizers. Ammonia is also used in the production of plastics, fibers, explosives, and intermediates for dyes and pharmaceuticals. Sulfuric acid is used in ore processing, fertilizer manufacturing, oil refining, wastewater processing, and chemical synthesis. Even for basic water treatment, the country has to import alum, which was a main product of the Ranala sulfuric acid plant. These two base materials could greatly impact the economy. Sri Lanka produces salt but still does not meet all its own needs, and even in the salt production process, the valuable brine solution (an intermediate product of salt processing) is pumped back into the sea without being used. In contrast, Dow Chemicals started by producing bromine from brine solution in the 1900s and has since become the second largest chemical company in the world, with a turnover larger than the GDP of Sri Lanka. The brine solution is electrolyzed in the "chloralkali process" to produce bromine, sodium hydroxide, chlorine, and hydrogen, as well as hypochlorite and chlorate, which are valuable and essential chemicals in the industrial world.
Sri Lanka is confident that it has oil resources and plans to start exploring them. However, in order to make the most of these resources, it is important to process crude oil within the country using local resources and to maximize product yield, which is not currently happening. While Sri Lanka does have some process industries, most of them rely on raw materials imported from other countries. It is acceptable to import certain materials if the country does not have them, but as Sri Lanka is a resource-rich nation, it is important to maximize the output from its own resources. The country wastes foreign exchange by importing a wide range of products, including food items, on which it depends for 60% of its basic food needs and spends more than 2 billion rupees per year. Despite being an agro-based society with many sources of food and potential for a proper food industry, Sri Lanka still imports food. The country also relies on petroleum-based fuels for transportation, power generation, and household use, rather than developing renewable alternatives such as bio diesel, bio gas, ethanol, and others.

Biodegradable Polythene using Cassava Starch
Non degradable polythene has been a heavy burden on environment. It causes decreasing soil fertility, clogging irrigation systems, affecting aesthetical beauty & destructive to wildlife & other biological system. So as chemical & process undergraduates we were delighted when we were given chance to engage with designing of biodegradable polymer.
Our country is basically agriculture based one. Because of too many reasons most of farmers loose profits from their yield. Same product comes into market in very large quantities in narrow time period. So farmers can not demand their product; unfortunately this scenario has been converted to grab the effort of farmers into intermediate traders’ wallet. We select cassava as the main row material in order to minimize the above tragic situation. When our research become a commercial reality it will help to give a high bid for farmers’ product.
We were given chance to select approach to the design project. We were given three alternatives to produce biodegradable polymer.
1. Using only starch
2. Using starch plus biodegradable polymer
3. Using starch plus non – biodegradable polymer (This alternative was given for worst case. That mans if we could not found any way to follow above two alternatives we would able to follow this option. )
Using only Starch
In environment lecture we were given a water bottle to observe which is made out of corn starch. Mervyn Dias from Plastic Packaging (Pvt) Ltd (PPCL) was introduced to us by our project coordinator. He discussed about his experiences in production of starch based polymers. These two junctures enhance our enthusiasm on this project & implies us to select total starch to produce our biodegradable polymer.

Developing University – School Interaction
_ Pictures will come soon _
Student society of Chemical Engineers Society Sri Lanka, ChESS organized a workshop for Advanced Level student of Embilipitiya area. This is organized in order to increase the interaction in between school & university community. We covered up industrial chemistry part of the Advanced Level syllabus. We present some of industrial chemistry practical using recorded video clips. All video clips were made up in university with our equipment & student. We did a presentation with a little video clip on bio gas generation additionally.
This program was totally funded by IRQUE project. So we were able to perform that workshop in ultimate condition with out warring about money. We gave them high quality education material. We additionally distribute some books on Bio Gas Generation which were given by Prof. Ajith de Alwis. Finally we gave them a MCQ paper with 15 questions related to areas which were covered up in work shop. Three Students with highest marks were gifted with special prizes.
This program was a success because of our unity, commitment of our lectures & our department staff. Every one in our department did their best towards this program. We scarify lot of our academic works to do this program. But finally we realize the value of our program by reading feed back forms.

Plasma arc decomposition of solid waste into non hazardous gasses & vitrified solids
This is somewhat high end approach to solid waste management. This is done using extremely hot flame generated by a plasma torch. This will be trusty way to get rid of some hazardous waste such as PCB (Polychlorinated biphenyls). The temperature of the flame is in a range of 10000 0F. Quite unbelievable temperature which is generated by special electrode consuming about three megawatts range electricity. But today prof. Ajith de Alwis said in Solid Waste Management lecture that the emitting gasses of this plasma reactor can be used to produce electricity which covers the consumption of electrical energy of reactor. In that case we only need a back up source of 3 megawatts electricity for considerably short time period. The rest of energy to run the plasma arc furnace can be obtained using emitting gasses. This is a good approach on solid waste management because this kind of high end technology will boost interest on environmental engineering & other related fields.
This video will give you a nice idea on plasma reactor which convert waste into valuble energy

Open Source Research Centre for Chemical & Process Engineering
Chemical & Process in also a field which can be developed further by doing R&Ds and continuous improvements. I think if there is open source research center which share their designs, experimental data & observation among each other, definetly there will be a boost in our industry.
As example we can do a research on environmental impact on solid waste in sri lanka & design a good systematic approach to get rid of it. We can freely published all information that we gathered & designed to all chemical & process engineers all over world. They can evaluate our work and they can add their comments & views. They also can contribute further on that research if they like to do so.
This will make rapid growth in our industry. If there is such a program developing countries can get maximum advantage, because our R&Ds are backing because of financial weaknesses.
We can not do this kind of effort with out financial strength. But we can ask founds from IChemE, World Bank, ADB, UN. This kind of effert do not want to make as opportunity to grab money. But we have to do something other than ordinary do to uplift our industry.

Our Identity can be seen from Outer Space
"The Great Wall of China is often cited as the only man-made structure that can be seen from space. However, there is now another contender for this title - the Fresh Kills Landfill on Staten Island, New York. As the largest garbage dumping site in the world, covering an area of 2200 acres, the Fresh Kills Landfill is a modern-day marvel that can be seen from outer space.
In addition to its impressive size, the Fresh Kills Landfill is also a major contributor to greenhouse gas emissions. As the largest single source of methane, a gas that is 25 times more potent than the most common greenhouse gas, carbon dioxide, the landfill has a significant impact on the Earth's climate.
The Fresh Kills Landfill was opened in 1948 and has continued to grow over the years. In fact, in 2001 its peak was 25 meters taller than the Statue of Liberty. It is not only the largest landfill in the world, but also the highest man-made hill. While the Fresh Kills Landfill may not have the same historical significance as the Great Wall of China, it is a testament to the modern world's ability to create structures that can be seen from space."
The Fresh Kills Landfill is a garbage dumping site located on the New York City borough of Staten Island. It is the largest landfill in the world, covering an area of 2200 acres. The Fresh Kills Landfill was opened in 1948 and has continued to grow over the years. In fact, in 2001 its peak was 25 meters taller than the Statue of Liberty, making it the highest man-made hill in the world.

As the largest single source of methane, a gas that is 25 times more potent than the most common greenhouse gas, carbon dioxide, the landfill has a significant impact on the Earth's climate.
Despite its environmental and health impacts, the Fresh Kills Landfill has continued to operate and receive waste from New York City and the surrounding areas. However, efforts have been made to reduce its size and impact through waste reduction and recycling programs. In 2001, the landfill was closed to new waste, and the city has been working to transform the site into a public park and recreational area.

Can she save this world behalf of us?
“When we plant trees, we plant the seeds of peace and seeds of hope." Prof. Wangari, Maathai, founder of the Green Belt Movement and 2004 Nobel Peace Prize Laureate.
We cut down trees for several needs. Although trees involved in our life cycle in numerous ways we do not mind on planting trees. But pioneers who see this world with a widen & perspective vision have started several campaigns to save this planet behalf of us.
United Nations Billion Tree Campaign is a brainchild of professor Wangari Mathai who is the first African woman won the Nobel Peace Prize. She is also the founder of
Professor Wangari Mathai expressed her idea on her campaign by saying “People talk too much. We are no longer talking, we are working. The challenge now is to tell the world to go dig holes and plant seedlings. I've no doubt we will achieve our goal.”

Success Story of DOW
Although the beginning of DOW is dated back to 1897, the success story of DOW is very interesting. It was founded by dedicated chemical industrialist Herbert Henry Dow. He showed his capabilities of innovation by making an incubator for chicken eggs before he was 12. After several years his father and he innovated a small steam turbine for US Navy. After graduating from high school he enrolled into Case School of Applied Science (Now it is known as
Herbert Henry Dow continued his researches in
A government-supported German bromine cartel, Bromkonvention began to sell bromine which was the main product of DOW at a very low cost than DOW price. This was planed tactic to eliminate DOW from
Now DOW is the second largest chemical company in world. It is known as Chemical Companies’ Chemical Company.

Biography of a great environmentalist & political activist
"I have warned people against false beliefs and misinformation such as attributing this disease to a curse from God or believing that sleeping with a virgin cures the infection. These prevalent beliefs in my region have led to an upsurge in rape and violence against children. It is within this context, also complicated by the cultural and religious perspective that I often speak. I have therefore been shocked by the ongoing debate, generated by what I am purported to have said. It is therefore critical for me to state that I neither say nor believe that the virus was developed by white people or white powers in order to destroy the African people. Such views are wicked and destructive"
We can understand her society background which is being changed by herself.
What is our scenario? It is not worst like this. Our people Sri Lankan have good values & our society has the ability to change. Then why there are poverty, war, conflicts ... etc available with in the society? I think we do not have good leaders to show us the path. Majority of our political activists are not educated well. They do not love our motherland. They do not need to develop our nation. That is why we are under developing.
Mohandas Karamchand Gandhi created a path to follow for Indians, Mohammad ali jinnah created a country for his people, Lee Kuan Yew influenced their people to develop. But for us? We need good leaders to uplift our nation. Most of educated and best people are not active in our society. Because of violence nature of our political environment most of best people are not involving in politics.

Do you know about Cassava well?
Most people think that cassava is not rich with nutrients. But it contains lot of starch & significant amounts of calcium (50 mg/100g), phosphorus (40 mg/100g) and vitamin C (25 mg/100g). The cassava roots do not contains protein, but cassava leaves contains protein.
Do you know that cassava can turn into ethanol which is a good alternative fuel for motor vehicles? Cassava based ethanol production researches have been conducted in various countries using pilot plant modules. It is proven that we can produce 185 - 200 lts of ethanol from 1 MT of cassava roots. The normal harvest of cassava is 29 MT root per hectare. So we can achieve a production of 5365 - 5800 ethanol from 1 hectare of manioc farm.
In Sri lanka we can see farmers suicide because of inability to sell their harvest. According to my humble knowledge turning cassava or some other starch based thing into ethanol is not a rocket sciences. We have fuel crisis, energy crisis & farmers burning financial problems to be solved. There are more alternatives for this kind of burning problems. We need only one thing to solve this problem. That is desire & kindness to help people. That is only factor that a scientist or an engineers driven to solve peoples problems.
