3. WHAT IS GREEN CHEMISTRY??
• GREEN CHEMISTRY IS ALSO CALLED
SUSTAINABLE CHEMISTRY.
• IT SEEKS TO REDUCE AND PREVENT
POLLUTION AT IT’S SOURCE.
• “GREEN CHEMISTRY IS THE DESIGN
OF CHEMICAL PRODUCTS &
PROCESSES THAT REDUCE OR
ELIMINATED THE USE & GENERATION
OF HAZARDOUS SUBSTANCES.”

4. HISTORY OF GREEN
CHEMISTRY
• THE POLLUTION PREVENTION ACT
PASSED IN 1990 IN UNITED STATES
EXPLORED THE IDEA OF GREEN
CHEMISTRY.

5. FATHER OF GREEN CHEMISTRY

6. PRINCIPLES OF GREEN
CHEMISTRY
• PAUL ANASTAS &JOHN C.WARNER
DEVELOPED 12 PRINCIPLES OF
GREEN CHEMISTRY TO EXPLAIN
WHAT THE DEFINITION MEANS
IN PRACTICE.

7. THE PRINCIPLES COVER SUCH
CONCEPTS AS:
 IT IS BETTER TO PREVENT WASTE
THAN TO TREAT OR CLEAN UP WASTE
AFTER IT IS FORMED;
 THE USE OF SAFE,ENVIRONMENT-
BENIGN SUBSTANCES,INCLUDING
SOLVENTS,WHENEVER POSSIBLE;
 THE DESIGN OF ENERGY EFFICIENT
PROCESSES;
 THE BEST FORM OF WASTE
DISPOSAL:NOT TO CREATE IT IN THE
FIRST PLACE.

8. IMPORTANCE OF GREEN
CHEMISTRY
• PREVENT WASTE
• DESIGN SAFER CHEMICALS & PRODUCTS
• USE RENEWABLE FEEDSTOCKS
• USE CATALYSTS,NOT STOICHOMETRIC
REAGENTS
• MAXIMIZE ATOM ECONOMY
• INCREASE ENERGY EFFICIENCY
• DESIGN CHEMICALS & PRODUCTS TO DEGRADE
AFTER USE
• ANALYZE IN REAL TIME TO PREVENT POLLUTION
• MINIMIZE THE POTENTIAL FOR ACCIDENTS.

9. HOW GREEN CHEMISTRY
SUPPORTS A TRANSITION TO
SUSTAINABLE AGRICULTURE
• GREEN CHEMISTRY & SUSTAINABLE
AGRICULTURE ARE INHERENTLY
INTERTWINED.
• FARMERS NEED GREEN CHEMISTS
TO MAKE SAFE AGRICULTURAL
CHEMICAL INPUT.

11. CONCLUSION
 FOCUS ON RENEWABLE ENERGY LEANS
TOWARD TYPES & DELIVERY
SYSTEMS;SOLAR,WIND,GEOTHERMAL, FUEL
CELLS,PHOTOVOLTAICS & TURBINES..
 THE NEXT LEVEL OF GREEN CHEMISTRY IS TO
FULLY SUPPORT THE RENEWABLE ENERGY
INDUSTRY & SOLVE IT’S PROBLEMS OF
MATERIALS, STORAGE & EFFICIENCY.
 GREEN CHEMISTRY SOLVING GLOBEL
WARMING IN ACTION.
