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.”

HISTORY OF GREEN CHEMISTRY

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

FATHER OF GREEN CHEMISTRY

PRINCIPLES OF GREEN CHEMISTRY

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

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.

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.

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.

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.
