WHY THIS TOPIC ?
Sustainability is a problem for the industry
Increasing awareness of people
Related with my field studies
![Page 4: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/4.jpg)
WHAT İS GREEN CHEMİSTRY?
Major aims:• Prevention of wastes• Increase energy efficiency• Cheaper processes• Reduced risks
![Page 5: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/5.jpg)
WHY GREEN CHEMİSTRY ?
Classical methods pollute environment
‘Old school’ chemistry is not efficient enough
Maximized sustainability
![Page 6: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/6.jpg)
WHAT İS A CATALYST ? They speed up chemical reactions
Used alot in chemical industry
Increases productivity
Lowers capital use
![Page 7: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/7.jpg)
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
![Page 13: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/13.jpg)
APPLİCATİON 2ENVİRONMENTALLY FRİENDLY CATALYSİS
Also called “green catalysis”
Has alot of advantages when compared to classical type of catalysis
Recently found method (~15 years)
![Page 14: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/14.jpg)
CLASSİCAL CATALSİS METHOD
Named as “Homogeneous Catalysis”
They are dumped to environment after use
Causing huge pollution problems
Financially ineffective
![Page 15: Applications of green chemistry](https://reader036.fdocuments.us/reader036/viewer/2022062307/556b1b73d8b42adb338b4a37/html5/thumbnails/15.jpg)
NEW METHOD OF CATALYSİS
Named as “Heterogeneous Catalysis”
Can be used over and over
Increases productivity
Saves alot of money

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

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”

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
