general information about bioplastic

1. BIODEGRADABLE PLASTICS

2. Introduction Plastics are used almost every where in the world Most of the things are made up of plastic, basically plastics are prepared from petroleum product. Nowadays, people are more aware about the harmful effects of plastic materials because the plastic materials not degraded by micro-organism and it cause the environmental polution . Bioplastic is the alternative source for the plastic . This bioplastic is made up of renewable resources like plant and agricultural waste product.

3. BIODEGRADABLE PLASTICS BIODEGRADABLE-Biologically broken down. BIODEGRADABLE PLASTICS –environmentally friendly plastics. Petrochemicals + Biological additives. ADDITIVE-Improves plasticity.

4. DEGRADATION PROCESS Decomposed by Bacteria , Fungi and Algae. The biological additives cause them to decay more rapidly. In the presence of light , oxygen , moisture and heat they are converted into Carbon dioxide , water and minerals.

5. 80% of degradation within 45 days. 90% of degradation within 80 days. TIME TAKEN FOR DEGRADATION

6. BIODEGRADABLE PLASTIC PRODUCTS COMMONLY USED CARRY BAGS GARBAGE BAGS WATER BOTTLES SPOONS.

7. BIODEGRADABLE PLASTIC USED IN AGRICULTURE- MULCH FILM

8. APPLICATION AREAS IN INDIA MULCH SURGICAL IMPLANTS INDUSTRIAL PACKAGING WRAPPING MILK SACHETS FOOD SERVICE PERSONAL CARE PHARMACEUTICALS MEDICAL DEVICES

9. PRODUCT SYNTHESIS AND DEGRADATION

10. PRODUCT APPLICATION BASED ON PROPERTIES SINGLE USE SHORT LIFE DISPOSABLE PRODUCTS STRENGTH RESISTANCE TO HEAT AND WATER ABILITY TO PACKAGE FOOD ITEMS

11. IDENTIFICATION BY TOUCH : SOFTER SILKIER QUALITY LABEL : EN134322 ‘OK COMPOST’

12. COST 2 TO 10 TIMES MORE THAN CONVENTIONAL PLASTICS BIODEGRADABLE PLASTIC FILM OR BAGS-Rs.400-500/Kg SOLUTION: STOPPING THE USAGE OF CONVENTIONAL PLASTICS PRODUCING MORE NUMBER OF BIODEGRADABLE PLASTICS.

13. RISK OF CONTAMINATION BIODEGRADABLE PLASTICS SHOULD NOT BE MIXED WITH NON-BIODEGRADABLE PLASTICS WHEN THROWN IN GARBAGE BINS WHEN MIXED DEGRADATION DOES NOT TAKE PLACE.

14. RULES TO BE FOLLOWED “ECO-LABELING” SYSTEM “PLASTICS CODING SYSTEM” (RECYCLED PLASTICS MANUFACTURE AND USAGE RULES , 1999, AS AMENDED IN 2003 MUST BE IMPLEMENTED).

15. ADVANTAGES CONSUMES LESS ENERGY- MORE PRODUCTION LESS LANDFILL AREA NEEDED RECYCLABLE NON-RENEWABLE RESOURCES LIKE PETROLEUM , NATURAL GAS AND COAL CAN BE PRESERVED.

16. DISADVANTAGES NEED FOR INDUSTRIAL COMPOSTERS IT MUST BE SEPARATED FROM CONVENTIONAL PLASTICS DURING DEGRADATION PROCESS.
