FLAVOURED CEREAL PACKAGING, COFFEE PACKS

SNACK FOOD, MILK AND FRESH YOGURT

COMPOST BAGS

ALL THE PRODUCTS ARE COMPLETELY BIODEGRADABLE IN COMMERCIAL COMPOST CONDITIONS

JUNE 2, 2001 IIT DELHI

EMERGING APPLICATIONS

BLOW MOLDING : IJECTION STRETCHED BLOW MOLDED BOTTLES

EMULSIONS : WATER BASED EMULSIONS FOR PAPER AND BOARD COATING, PAINTS, BINDERS FOR NON-WOVENS, ADHESIVES

LACTIC ACID DERIVATIVES AS

CHEMICAL INTERMEDIATES FOR HOT MELT ADHESIVE, SURFACTANT, ACRYLIC ESTER

JUNE 2, 2001 IIT DELHI

REDUCE FOSSIL FUEL USE

CONVENTIONAL HYDROCARBON POLYMERS UTILIZE OIL AS THEIR FEEDSTOCK SOURCE

MONOMER FOR PLA IS DERIVED FROM ANNUALLY RENEWABLE RESOURCE

ENERGY FROM SUN AND CARBON DIOXIDE FROM AIR ARE HARNESSED IN AGICULTURE CROPS

ENVIRONMENTAL BENEFITS

JUNE 2, 2001 IIT DELHI

ONE THIRD OF THE ENERGY REQUIREMENT OF PLA IS DERIVED FROM THESE RENEWABLE RESOURCES

PLA UTILIZE 20 - 40% LESS FOSSIL FUEL THAN OTHER POLYMERS DERIVED DIRECTLY FROM HYDROCARBONS

FOSSIL FUEL PROVIDES ENERGY TO RUN PLA PRODUCTION CHAIN e.g. MILLING , FERMENTATION , POLYMERIZATION AND TRANSPORTATION

JUNE 2, 2001 IIT DELHI

CARBON CYCLE

CARBON DIOXIDE IS MAJOR CONTRIBUTOR TO GLOBAL WARMING

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

JUNE 2, 2001 IIT DELHI

BIODEGRADABILITY OF PLA

PLA FIBRE WHEN SUBJECTED TO GROUND BURRYING, MARINE WATER AND ACTIVATED MUD TESTS

DECREASE IN TENACITY

INCREASE IN WEIGHT LOSS

IN GROUNDAND MARINE WATER TESTS THE FIBRE IS PRACTICALLY DECOMPOSED WITHIN TWO YEARS

ACTIVATED MUD TEST, DECOMPOSITION IN 2-3 MONTHS

JUNE 2, 2001 IIT DELHI

COMPARISON WITH TRADITIONAL FIBRES

CONVENTIONAL PET RETAINS THE SHAPE AND PROPERTIES UNDER ALL BIODEGRADABILITY TESTS

CELLULOSIC FIBRES (COTTON AND VISCOSE) ARE DECOMPOSED MORE RAPIDLY THAN PLA IN ACTIVATED MUD

JUNE 2, 2001 IIT DELHI

WASTE DISPOSAL

PLA PRODUCTS CAN BE DISPOSED OFF BY TRADITIONAL WASTE MANAGEMENT METHODS SUCH AS

LANDFILL

LANDFILL TESTS HAVE NOT BEEN CARRIED OUT WITH PLA POLYMERS

ITS WATER INDUCED (HYDROLYSIS) DEGRADATION MECHANISM IS WELL UNDERSTOOD

JUNE 2, 2001 IIT DELHI

IN PRESENCE OF MOISTURE PLA POLYMERS DEGRADE INTO LACTIC ACID (MONOMER) EVEN IF MICROBES ARE NOT PRESENT

PLA POLYMER DEGRADATION RATE IS DEPENDENT ON TEMPERATURE AND HUMIDITY

AT TYPICAL LANDFILL TEMPERTATURES, THE EXPECTED DEGRADATION TIME FRAME WOULD BE BETWEEN 2 AND 10 YEARS

FOOD WASTE AND PAPER MAY PERSIST FOR LONGER PERIOD IN LANDFILL BECAUSE THEY REQUIRE BACTERIA TO DEGRADE

JUNE 2, 2001 IIT DELHI

INCINERATION

PLA POLYMERS INCINERATE CLEANLY WITH REDUCED ENERGY YIELD COMPARED TO TRADITIONAL POLYMERS

PLA POLYMERS BURN MUCH LIKE PAPER AND CELLULOSE

BURNS WITH WHITE FLAME

IT CONTAINS NO AROMATIC GROUPS OR CHLORINE

PRODUCES FEW BY PRODUCTS AND 0.01% ASH.

JUNE 2, 2001 IIT DELHI

MUNICIPAL COMPOSTING

PLA POLYMERS ARE FULLY COMPOSTABLE IN MUNICIPAL COMPOSTING FACILILITIES

PLA COMPOST CAN BE RECYCLED FOR CORN CULTIVATION

PLA POLYMERS COMPOST BY TWO STEP PROCESS

JUNE 2, 2001 IIT DELHI

FIRST CHEMICAL HYDROLYSIS (REACTION WITH WATER) REDUCES THE MOLECULAR WEIGHT OF POLYMER

THEN MICRO ORGANISMS DEGRADE THE FRAGMENTS AND LACTIC ACID INTO CARBON DIOXIDE AND WATER

HEAT AND WATER STIMULATE DEGRADATION OF PLA POLYMERS

JUNE 2, 2001 IIT DELHI

CONCLUSIONS

THE NEW ECO FRIENDLY SYNTHETIC FIBRE BASED ON CORN AS RENEWABLE SOURCE WOULD FIND WIDE ACCEPTABILITY IN THE AREA OF

CONVENTIONAL TEXTILES

TECHNICAL TEXTILES

NON TEXTILE APPLICATIONS

JUNE 2, 2001 IIT DELHI

IT WOULD MEET TH E REQUIREMENTS TO COPE UP WITH THE DEPLETING FOSSIL FUEL RESOURCES AND ENVIRONMENT PROTECTION

IT IS ENVISAGED THAT IN THE NEAR FUTURE MANY COMPANIES WOULD ENTER INTO PRODUCTION OF ECO FRIEDNLY PLA FIBRES AND OTHER PRODUCTS.
