Biodegradable plastics are made from renewable resources like plants and agricultural waste instead of petroleum. They are broken down by microorganisms and convert into carbon dioxide, water and minerals. Most biodegradable plastics will degrade 80% within 45 days and 90% within 80 days when exposed to light, oxygen, moisture and heat. Common products made from biodegradable plastics include carry bags, garbage bags, water bottles and spoons. They are used in applications like agriculture, packaging, and disposable items. While more expensive than conventional plastics, biodegradable plastics preserve resources and reduce environmental pollution.

1. BIODEGRADAB
LE 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.

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

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

12. BIODEGRADABLE PLASTIC
USED IN AGRICULTURE- MULCH FILM

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

14. PRODUCT SYNTHESIS AND DEGRADATION

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

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

17. 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.

18. 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.

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

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

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