Conclusion

WHY THIS TOPIC ?

Sustainability is a problem for the industry

Increasing awareness of people

Related with my field studies

WHAT İS GREEN CHEMİSTRY?

Major aims:• Prevention of wastes• Increase energy efficiency• Cheaper processes• Reduced risks

WHY GREEN CHEMİSTRY ?

Classical methods pollute environment

‘Old school’ chemistry is not efficient enough

Maximized sustainability

WHAT İS A CATALYST ? They speed up chemical reactions

Used alot in chemical industry

Increases productivity

Lowers capital use

WHAT İS WASTE ? Wastes are materials that we can’t

make use of them

They are produced undesirably while we are trying to get our product

They pollute our environment

PLANT İNTEGRATİON

“One plant’s waste is other plant’s raw material” approach

Eliminates the waste

Reduces the operating costs

APPLİCATİON 2ENVİRONMENTALLY FRİENDLY CATALYSİS

APPLİCATİON 2ENVİRONMENTALLY FRİENDLY CATALYSİS

Also called “green catalysis”

Has alot of advantages when compared to classical type of catalysis

Recently found method (~15 years)

CLASSİCAL CATALSİS METHOD

Named as “Homogeneous Catalysis”

They are dumped to environment after use

Causing huge pollution problems

Financially ineffective

NEW METHOD OF CATALYSİS

Named as “Heterogeneous Catalysis”

Can be used over and over

Increases productivity

Saves alot of money

EXAMPLE SYNTHESİS

CURRENT SİTUATİON

• Environmentally Friendly Catalysis:

• Subsequently reduced the catalyst costs

• Has earned the second biggest share in the market

• With high selectivity, operating costs went down

APPLİCATİON 3BİOMASS

BİOMASS

Bio-Mass;Uses the living organisms (vegetables and

plants) to get useful energy

Has a great potential to;Be developed in the industrySolve the current sustainability problems

Completely “green”

CONCLUSİON Green chemistry is very environmental

friendly and efficient

Green Chemistry Applications Industrial integrationEnvironmentally friendly catalysisBiomass

Apply green chemistry to; reduce fuel oil consumption prevent the damage to environment

END PRODUCT

I designed the end product such that:All people can access Information will be easy to followPeople will be aware of situation after

visitingHopefully people who are aware, will take

action

PROBLEMS İ HAD WHİLE RESEARCH

Since it is a new topic,Available data for industry changes in time

Amount of information is scarce;Some companies keep their data as secretAvailable sources are hard to reach
