guy a petrochemical plant which uses fossil fuels worldwide petrochemical

fossil fuels worldwide petrochemical

fossil fuels worldwide petrochemical plants released billions of tons of co2

plants released billions of tons of co2

plants released billions of tons of co2 into the atmosphere every year I looked

into the atmosphere every year I looked

into the atmosphere every year I looked it up

it up

it up a typical petrochemical plant release

a typical petrochemical plant release

a typical petrochemical plant release more co2 than all the seven billion

more co2 than all the seven billion

more co2 than all the seven billion people on the earth right now and guess

people on the earth right now and guess

people on the earth right now and guess what there are hundreds of petrochemical

what there are hundreds of petrochemical

what there are hundreds of petrochemical plants out there so can you imagine the

plants out there so can you imagine the

plants out there so can you imagine the impact of this industry in climate

impact of this industry in climate

impact of this industry in climate change and global warming so I have been

change and global warming so I have been

change and global warming so I have been thinking about waste and pollutants for

thinking about waste and pollutants for

thinking about waste and pollutants for quite some time in fact from my high

quite some time in fact from my high

quite some time in fact from my high school days I grew up in Sri Lanka and

school days I grew up in Sri Lanka and

school days I grew up in Sri Lanka and on my way to high school I used to pass

on my way to high school I used to pass

on my way to high school I used to pass by this oil refinery so from far I could

by this oil refinery so from far I could

by this oil refinery so from far I could see how the waste and pollutants release

see how the waste and pollutants release

see how the waste and pollutants release into the atmosphere

after my high school I moved to

after my high school I moved to Singapore to pursue my university

Singapore to pursue my university

Singapore to pursue my university studies to become a chemical engineer

studies to become a chemical engineer

studies to become a chemical engineer over there I had the opportunity to

over there I had the opportunity to

over there I had the opportunity to in a petrochemical plant I we our

in a petrochemical plant I we our

in a petrochemical plant I we our business the waste and pollutants

business the waste and pollutants

business the waste and pollutants release into the atmosphere now in

release into the atmosphere now in

release into the atmosphere now in Belgium I am working with waste of base

Belgium I am working with waste of base

Belgium I am working with waste of base from fossil fuels like co2 so I always

from fossil fuels like co2 so I always

from fossil fuels like co2 so I always get the question why can’t we get rid of

get the question why can’t we get rid of

get the question why can’t we get rid of fossil fuels and use renewable energies

fossil fuels and use renewable energies

fossil fuels and use renewable energies it turns out fossil fuels form the

it turns out fossil fuels form the

it turns out fossil fuels form the fundamental building block of our

fundamental building block of our

fundamental building block of our society they’re cheap abundant contains

society they’re cheap abundant contains

society they’re cheap abundant contains large amount of energy so even though we

large amount of energy so even though we

large amount of energy so even though we desire a world where we no longer need

desire a world where we no longer need

desire a world where we no longer need fossil fuels we are not quite there yet

fossil fuels we are not quite there yet

fossil fuels we are not quite there yet so can we at least deal with the waste

so can we at least deal with the waste

so can we at least deal with the waste from fossil fuels can we consider co2 as

from fossil fuels can we consider co2 as

from fossil fuels can we consider co2 as a resource not as a waste

a resource not as a waste

a resource not as a waste Buckminster Fuller an American professor

famous for his buckyballs just looks like the chemistry of food chemist

like the chemistry of food chemist

like the chemistry of food chemist football of chemistry put it best when

football of chemistry put it best when

football of chemistry put it best when he said pollution is nothing but the

he said pollution is nothing but the

he said pollution is nothing but the resources we are not harvesting we

resources we are not harvesting we

resources we are not harvesting we allowed we allow them to disperse

allowed we allow them to disperse

allowed we allow them to disperse because we have been ignorant of their

because we have been ignorant of their

because we have been ignorant of their value so using chemistry we can convert

value so using chemistry we can convert

value so using chemistry we can convert co2 into high-value products well this

co2 into high-value products well this

co2 into high-value products well this sounds like a science fiction or coming

sounds like a science fiction or coming

sounds like a science fiction or coming up with a really complex process but

up with a really complex process but

up with a really complex process but actually the way we do is quite simple

actually the way we do is quite simple

actually the way we do is quite simple co2 has one carbon and two oxygen atoms

co2 has one carbon and two oxygen atoms

co2 has one carbon and two oxygen atoms so what are these high value products

so what are these high value products

so what are these high value products like petrol and diesel so they

like petrol and diesel so they

like petrol and diesel so they essentially long chains of carbon and

essentially long chains of carbon and

essentially long chains of carbon and hydrogen atoms

hydrogen atoms

hydrogen atoms I guess everyone here played with Legos

I guess everyone here played with Legos

I guess everyone here played with Legos before right so when you play with Legos

before right so when you play with Legos

before right so when you play with Legos we take one Lego block at a time and we

we take one Lego block at a time and we

we take one Lego block at a time and we connect this Lego blocks to get a great

connect this Lego blocks to get a great

connect this Lego blocks to get a great structure can we do the same with co2 so

structure can we do the same with co2 so

structure can we do the same with co2 so if we can take the carbon atom from co2

if we can take the carbon atom from co2

if we can take the carbon atom from co2 we can use it as a carbon one building

we can use it as a carbon one building

we can use it as a carbon one building block so we can take this carbon

block so we can take this carbon

block so we can take this carbon building blocks connect with hydrogen

building blocks connect with hydrogen

building blocks connect with hydrogen and we can get this high value products

and we can get this high value products

and we can get this high value products like

like

like DISA bit of a challenge because co2 is

DISA bit of a challenge because co2 is

DISA bit of a challenge because co2 is very stable meaning it doesn’t like to

very stable meaning it doesn’t like to

very stable meaning it doesn’t like to break its carbon and oxygen bonds so to

break its carbon and oxygen bonds so to

break its carbon and oxygen bonds so to help with this we need something called

help with this we need something called

help with this we need something called catalyst so catalysts will activate the

catalyst so catalysts will activate the

catalyst so catalysts will activate the co2 and it will break its carbon and

co2 and it will break its carbon and

co2 and it will break its carbon and oxygen bonds so catalysts are materials

oxygen bonds so catalysts are materials

oxygen bonds so catalysts are materials which increases the speed of reaction

which increases the speed of reaction

which increases the speed of reaction without being consumed I like to think

without being consumed I like to think

without being consumed I like to think catalyst as the person who helps to

catalyst as the person who helps to

catalyst as the person who helps to register marriage during your wedding

register marriage during your wedding

register marriage during your wedding ceremony so the marriage registrar has a

ceremony so the marriage registrar has a

ceremony so the marriage registrar has a key role in determining how fast the

key role in determining how fast the

key role in determining how fast the ceremony takes place but not permanently

ceremony takes place but not permanently

ceremony takes place but not permanently change because of the ceremony

change because of the ceremony

change because of the ceremony unlike the couple who are permanently

unlike the couple who are permanently

unlike the couple who are permanently changed because of the marriage

changed because of the marriage

changed because of the marriage sometimes for the better sometimes for

sometimes for the better sometimes for

sometimes for the better sometimes for not so better so the next question comes

not so better so the next question comes

not so better so the next question comes to our mind how can we design a catalyst

to our mind how can we design a catalyst

to our mind how can we design a catalyst which can help us to convert co2 into

which can help us to convert co2 into

which can help us to convert co2 into high-value products traditionally

high-value products traditionally

high-value products traditionally scientists synthesize hundreds of

scientists synthesize hundreds of

scientists synthesize hundreds of materials and do thousands of

materials and do thousands of

materials and do thousands of experiments to find a good catalyst this

experiments to find a good catalyst this

experiments to find a good catalyst this is trial and error approach it takes

is trial and error approach it takes

is trial and error approach it takes lots of lots of time money and energy

lots of lots of time money and energy

lots of lots of time money and energy well I design catalyst using computers

well I design catalyst using computers

well I design catalyst using computers the aim is to really understand the

the aim is to really understand the

the aim is to really understand the chemistry happens at atomic level which

chemistry happens at atomic level which

chemistry happens at atomic level which is something experiments can’t do so

is something experiments can’t do so

is something experiments can’t do so this commission is completely safe and

this commission is completely safe and

this commission is completely safe and we only need to solve shooting the

we only need to solve shooting the

we only need to solve shooting the equation so before you ask shooting is

equation so before you ask shooting is

equation so before you ask shooting is the scientists with the Cathy Nawabs but

the scientists with the Cathy Nawabs but

the scientists with the Cathy Nawabs but solving shooting the equation is also

solving shooting the equation is also

solving shooting the equation is also difficult therefore we can only consider

difficult therefore we can only consider

difficult therefore we can only consider small catalyst structures and to solve

small catalyst structures and to solve

small catalyst structures and to solve these small català structures mini

these small català structures mini

these small català structures mini giant supercomputers like this so with

giant supercomputers like this so with

giant supercomputers like this so with the help of this giant supercomputers we

the help of this giant supercomputers we

the help of this giant supercomputers we can convert co2 into high value products

can convert co2 into high value products

can convert co2 into high value products so we are developing catalysts to

so we are developing catalysts to

so we are developing catalysts to convert this and I hope one day we can

convert this and I hope one day we can

convert this and I hope one day we can sit together and drink a beer which is

sit together and drink a beer which is

sit together and drink a beer which is made from co2 so does this mean co2 is

made from co2 so does this mean co2 is

made from co2 so does this mean co2 is good should we continue to make more co2

good should we continue to make more co2

good should we continue to make more co2 they know because we are releasing way

they know because we are releasing way

they know because we are releasing way too much co2 into the atmosphere then

too much co2 into the atmosphere then

too much co2 into the atmosphere then what we can actually can capture and

what we can actually can capture and

what we can actually can capture and utilize so here are two ideas were

utilize so here are two ideas were

utilize so here are two ideas were sharing

sharing

sharing first there’s nothing called waste just

first there’s nothing called waste just

first there’s nothing called waste just like the case of co2 our history is full

like the case of co2 our history is full

like the case of co2 our history is full of examples of things where we once

of examples of things where we once

of examples of things where we once considered it to be a waste but later we

considered it to be a waste but later we

considered it to be a waste but later we realized there of their good resources

realized there of their good resources

realized there of their good resources second is a message of hope I know all

second is a message of hope I know all

second is a message of hope I know all the news out there about pollution is

the news out there about pollution is

the news out there about pollution is negative and there and rightfully so but

negative and there and rightfully so but

negative and there and rightfully so but that doesn’t mean there’s no hope

that doesn’t mean there’s no hope

that doesn’t mean there’s no hope scientists are working around the clock

scientists are working around the clock

scientists are working around the clock and hopefully the solutions are around

and hopefully the solutions are around

and hopefully the solutions are around the corner thank you very much
