  13. 14. <ul><li>WIDE VARIETY OF MULTI-LAYER FILMS FOR PACKAGING USES SUCH AS FLAVOURED CEREALS, COFFEE PACKS AND PET FOODS </li></ul><ul><li>WINDOW FILMS FOR ENVELOPS </li></ul><ul><li>LAMINATION FILMS </li></ul><ul><li>RIGID THERMOFORMED CONTAINERS </li></ul>
  14. 15. END USE PRODUCTS <ul><li>PACKAGING OF DAIRY PRODUCTS </li></ul><ul><li>CANDY WRAPS </li></ul><ul><li>FAST FOOD CUPS </li></ul><ul><li>FRESH FOOD CONTAINERS </li></ul><ul><li>ICE CREAM HOLDERS </li></ul>
  15. 16. <ul><li>FLAVOURED CEREAL PACKAGING, COFFEE PACKS </li></ul><ul><li>SNACK FOOD, MILK AND FRESH YOGURT </li></ul><ul><li>COMPOST BAGS </li></ul><ul><li>ALL THE PRODUCTS ARE COMPLETELY BIODEGRADABLE IN COMMERCIAL COMPOST CONDITIONS </li></ul>
  16. 17. EMERGING APPLICATIONS <ul><li>BLOW MOLDING : IJECTION STRETCHED BLOW MOLDED BOTTLES </li></ul><ul><li>EMULSIONS : WATER BASED EMULSIONS FOR PAPER AND BOARD COATING, PAINTS, BINDERS FOR NON-WOVENS, ADHESIVES </li></ul><ul><li>LACTIC ACID DERIVATIVES AS </li></ul><ul><li>CHEMICAL INTERMEDIATES FOR HOT MELT ADHESIVE, SURFACTANT, ACRYLIC ESTER </li></ul>
  17. 18. <ul><li>REDUCE FOSSIL FUEL USE </li></ul><ul><li>CONVENTIONAL HYDROCARBON POLYMERS UTILIZE OIL AS THEIR FEEDSTOCK SOURCE </li></ul><ul><li>MONOMER FOR PLA IS DERIVED FROM ANNUALLY RENEWABLE RESOURCE </li></ul><ul><li>ENERGY FROM SUN AND CARBON DIOXIDE FROM AIR ARE HARNESSED IN AGICULTURE CROPS </li></ul>ENVIRONMENTAL BENEFITS
  18. 19. <ul><li>ONE THIRD OF THE ENERGY REQUIREMENT OF PLA IS DERIVED FROM THESE RENEWABLE RESOURCES </li></ul><ul><li>PLA UTILIZE 20 - 40% LESS FOSSIL FUEL THAN OTHER POLYMERS DERIVED DIRECTLY FROM HYDROCARBONS </li></ul><ul><li>FOSSIL FUEL PROVIDES ENERGY TO RUN PLA PRODUCTION CHAIN e.g. MILLING , FERMENTATION , POLYMERIZATION AND TRANSPORTATION </li></ul>
  19. 20. CARBON CYCLE <ul><li>CARBON DIOXIDE IS MAJOR CONTRIBUTOR TO GLOBAL WARMING </li></ul><ul><li>BECAUSE CARBON DIOXIDE IS REMOVED FROM AIR WHEN CORN IS GROWN , PLA HAS THE POTENTIAL TO RESULT IN REDUCED IMPACT ON GLOBAL WARMING COMPARED TO MOST HYDROCARBON BASED POLYMERS </li></ul>
  20. 21. BIODEGRADABILITY OF PLA <ul><li>PLA FIBRE WHEN SUBJECTED TO GROUND BURRYING, MARINE WATER AND ACTIVATED MUD TESTS </li></ul><ul><li>DECREASE IN TENACITY </li></ul><ul><li>INCREASE IN WEIGHT LOSS </li></ul><ul><li>IN GROUNDAND MARINE WATER TESTS THE FIBRE IS PRACTICALLY DECOMPOSED WITHIN TWO YEARS </li></ul><ul><li>ACTIVATED MUD TEST, DECOMPOSITION IN 2-3 MONTHS </li></ul>
  21. 22. <ul><li>COMPARISON WITH TRADITIONAL FIBRES </li></ul><ul><li>CONVENTIONAL PET RETAINS THE SHAPE AND PROPERTIES UNDER ALL BIODEGRADABILITY TESTS </li></ul><ul><li>CELLULOSIC FIBRES (COTTON AND VISCOSE) ARE DECOMPOSED MORE RAPIDLY THAN PLA IN ACTIVATED MUD </li></ul>
  22. 23. WASTE DISPOSAL <ul><li>PLA PRODUCTS CAN BE DISPOSED OFF BY TRADITIONAL WASTE MANAGEMENT METHODS SUCH AS </li></ul><ul><li>LANDFILL </li></ul><ul><li>LANDFILL TESTS HAVE NOT BEEN CARRIED OUT WITH PLA POLYMERS </li></ul><ul><li>ITS WATER INDUCED (HYDROLYSIS) DEGRADATION MECHANISM IS WELL UNDERSTOOD </li></ul>
  23. 24. <ul><li>IN PRESENCE OF MOISTURE PLA POLYMERS DEGRADE INTO LACTIC ACID (MONOMER) EVEN IF MICROBES ARE NOT PRESENT </li></ul><ul><li>PLA POLYMER DEGRADATION RATE IS DEPENDENT ON TEMPERATURE AND HUMIDITY </li></ul><ul><li>AT TYPICAL LANDFILL TEMPERTATURES, THE EXPECTED DEGRADATION TIME FRAME WOULD BE BETWEEN 2 AND 10 YEARS </li></ul><ul><li>FOOD WASTE AND PAPER MAY PERSIST FOR LONGER PERIOD IN LANDFILL BECAUSE THEY REQUIRE BACTERIA TO DEGRADE </li></ul>
  24. 25. INCINERATION <ul><li>PLA POLYMERS INCINERATE CLEANLY WITH REDUCED ENERGY YIELD COMPARED TO TRADITIONAL POLYMERS </li></ul><ul><li>PLA POLYMERS BURN MUCH LIKE PAPER AND CELLULOSE </li></ul><ul><li>BURNS WITH WHITE FLAME </li></ul><ul><li>IT CONTAINS NO AROMATIC GROUPS OR CHLORINE </li></ul><ul><li>PRODUCES FEW BY PRODUCTS AND 0.01% ASH. </li></ul>
  25. 26. <ul><li>MUNICIPAL COMPOSTING </li></ul><ul><li>PLA POLYMERS ARE FULLY COMPOSTABLE IN MUNICIPAL COMPOSTING FACILILITIES </li></ul><ul><li>PLA COMPOST CAN BE RECYCLED FOR CORN CULTIVATION </li></ul><ul><li>PLA POLYMERS COMPOST BY TWO STEP PROCESS </li></ul>
  26. 27. <ul><li>FIRST CHEMICAL HYDROLYSIS (REACTION WITH WATER) REDUCES THE MOLECULAR WEIGHT OF POLYMER </li></ul><ul><li>THEN MICRO ORGANISMS DEGRADE THE FRAGMENTS AND LACTIC ACID INTO CARBON DIOXIDE AND WATER </li></ul><ul><li>HEAT AND WATER STIMULATE DEGRADATION OF PLA POLYMERS </li></ul>
  27. 28. CONCLUSIONS <ul><li>THE NEW ECO FRIENDLY SYNTHETIC FIBRE BASED ON CORN AS RENEWABLE SOURCE WOULD FIND WIDE ACCEPTABILITY IN THE AREA OF </li></ul><ul><li>CONVENTIONAL TEXTILES </li></ul><ul><li>TECHNICAL TEXTILES </li></ul><ul><li>NON TEXTILE APPLICATIONS </li></ul>
  28. 29. <ul><li>IT WOULD MEET TH E REQUIREMENTS TO COPE UP WITH THE DEPLETING FOSSIL FUEL RESOURCES AND ENVIRONMENT PROTECTION </li></ul><ul><li>IT IS ENVISAGED THAT IN THE NEAR FUTURE MANY COMPANIES WOULD ENTER INTO PRODUCTION OF ECO FRIEDNLY PLA FIBRES AND OTHER PRODUCTS. </li></ul>
