General idea of Green chemistry and it's principles. It's need and importance in today's world. Benefits and examples of green solvents and their significant importance and uses.

1. GREEN CHEMISTRY
BY MUSKAN T.

2. OUR AGENDA
•WHAT DO MEAN BY GREEN CHEMISTRY
•WHEN WAS THE FIRST TIME THIS WORD USED
•WHO GAVE THE WORD GREEN CHEMISTRY
•WHAT WAS THE NEED TO DEVELOP GREEN CHEMISTRY CONCEPT
•WHAT ARE ITS PRINCIPLES
•HOW AND WHERE THIS CONCEPT IS USED MAINLY
•BY THE END OF THIS PRESENTATION I M SURE YOU ALL WILL BE ABLE TO
ANSWER THIS QUESTION

3. WHAT IS GREEN CHEMISTRY
•DEFINITION
•GREEN CHEMISTRY IS THE DESIGN OF CHEMICAL PRODUCTS
AND PROCESSES THAT REDUCE OR ELIMINATE THE USE OR
GENERATION OF HAZARDOUS SUBSTANCES

4. NEED FOR GREEN CHEMISTRY
•WITH THE ADVANCEMENT IN CHEMISTRY WORLD ,THERE WAS A RAPID INCREASE IN
HAZARDOUS WASTE WITH ADVERSE SIDE EFFECTS LEADING TO ENVIRONMENAL DAMAGE .
•DUE TO INCREASING USE OF HARMFUL CHEMICALS ,THERE WAS AN URGENT NEED TO
REDUCE CHEMICAL POLLUTION IN ORDER TO TACKLE ITS ADVERSE EFFECTS ON HUMAN LIFE
AND MARINE LIFE .
•IN 1970,U.S ESTABLISHED EPA (ENVIRONMENTAL PROTECTION AGENCY) WITH A AIM TO
PROTECT HUMAN AND ENVIRONMENTAL HEALTH BY SETTING AND ENFORCING
ENVIRONMENTAL REGULATIONS.

5. 3 WS (WHEN,WHERE AND WHO GAVE THIS
CONCEPT)……….???
• THE CONCEPT OF GREEN CHEMISTRY WAS FIRST ORIGINATED BY TREVOR KLETZ IN 1978
IN HIS PAPER
• IN 1990 ,THIS CONCEPT GOT FORMALLY ESTABLISHED AS A RESPONSE TO POLLUTION
PREVENTION ACT 1990 BY US EPA .
• LATER ON IN 1991 ,PAUL ANASTAS FOR THE FIRST TIME COINED THE TERM’ GREEN
CHEMISTRY’.
• PAUL ANASTAS IS WIDELY KNOWN AS FATHER OF GREEN CHEMISTRY .
• IN THE YEAR 1996 ,THE NAME GREEN CHEMISTRY WAS OFFICIALLY ADOPTED .

7. GOALS OF GREEN CHEMISTRY :-
•TO REDUCE THE AMOUNT OF POLLUTION GENERATED.
•TO PREVENT THE PRODUCTION OF POLLUTANT
•TO REGULATE THE QUANTITY AND TYPE OF EMISSIONS
•TO AVOID THE CREATION OF TOXIC BY PRODUCTS AND WASTE.
•TO IMPROVE THE YIELD EFFICIENCY OF CHEMICAL PRODUCTS .

8. IMPORTANCE OF GREEN CHEMISTRY
•IN 1998, PAUL ANASTAS AND JOHN C. WARNER PUBLISHED TWELVE PRINCIPLES OF
GREEN CHEMISTRY
•THE PRINCIPLES COVER SUCH CONCEPTS AS :-
1. THE DESIGN OF PROCESSES TO MAXIMIZE THE AMOUNT OF RAW MATERIAL THAT ENDS UP IN
THE PRODUCT.
2. THE USE OF RENEWABLE MATERIAL FEEDSTOCKS AND ENERGY SOURCES
3. THE USE OF SAFE, ENVIRONMENTALLY BENIGN SUBSTANCES, INCLUDING SOLVENTS, WHENEVER
POSSIBLE.
4. THE DESIGN OF ENERGY EFFICIENT PROCESSES.
5. AVOIDING THE PRODUCTION OF WASTE, WHICH IS VIEWED AS THE IDEAL FORM OF WASTE
MANAGEMENT.

9. PRINCIPLES OF GREEN CHEMISTRY
•1 .WASTE PREVENTION
•2.ATOM ECONOMY
•3.LESS HAZARDOUS CHEMICAL SYNTHESES
•4.DESIGNING SAFER CHEMICALS
•5.SAFER SOLVENTS AND AUXILIARIES
•6.DESIGN FOR ENERGY EFFICIENCY

10. PRINCIPLES OF GREEN CHEMISTRY
•7.USE OF RENEWABLE FEEDSTOCKS
•8.REDUCE DERIVATIVES
•9.CATALYSIS
•10.DESIGN FOR DEGRADATION
•11.REAL-TIME ANALYSIS FOR POLLUTION PREVENTION
•12.SAFER CHEMISTRY FOR ACCIDENT PREVENTION

12. BENEFITS OF GREEN CHEMISTRY

13. EXAMPLES AND USES
• 1.GREEN SOLVENTS:- GREEN SOLVENTS, ALSO KNOWN AS ENVIRONMENTALLY FRIENDLY BIO
SOLVENTS WHICH ARE DERIVED FROM THE PROCESSING OF CROPS.
• THE MAJOR APPLICATION OF SOLVENTS IN HUMAN ACTIVITIES IS IN PAINTS AND COATINGS.
• TRADITIONAL SOLVENTS ARE OFTEN TOXIC OR ARE CHLORINATED. GREEN SOLVENTS, ON THE
OTHER HAND, ARE GENERALLY LESS HARMFUL TO HEALTH AND THE ENVIRONMENT AND
PREFERABLY MORE SUSTAINABLE.
• A GREEN SOLVENT IS THE SOLVENT THAT MAKES A PRODUCT OR PROCESS HAVE THE LEAST
ENVIRONMENTAL IMPACT OVER ITS ENTIRE LIFE CYCLE.
• EXAMPLE :-WATER,SUPERCRITICAL CARBON DIOXIDE (SCCO2),PEG (POLYETHYLENE GLYCOL)
EHTHYL LACTATE ,ETC.
• 2.GREEN PAINTS
• 3.GREEN PLASTICS
• 3.GREEN CARPETS

15. CONCLUSION
•GREEN CHEMISTRY IS NOT THE SOLUTION TO ALL THE ENVIRONMENTAL
PROBLEMS BUT IT IS A MOST FUNDAMENTAL APPROACH TO PREVENT
POLLUTION.
•IT IS SUSTAINABLE , ENERGY EFFICIENT ,ECONOMICAL ,LESS HAZARDOUS
,TIME CONSUMING,NON TOXIC AND MOST IMPORTANTLY IT CONTROLS
POLLUTION AND MINIMISES THE TOXIC BY- PRODUCTS AND WASTES FROM
ENVIRONMENT .
