Biodegradable plastic alongwith their types and applications.

Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms.

Two basic classes of biodegradable plastics:
1) Bioplastic
Bioplastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, pea starch or microbiota. Common plastics, such as fossil-fuel plastics, are derived from petroleum- these plastics rely more on fossil fuels and produce more greenhouse gas. Some, but not all, bioplastics are designed to biodegrade.

Applications of Bioplastic:
Biodegradable bioplastics are used for disposable items, such as  [packaging] and catering items (crockery, cutlery, pots, bowls, straws). They are also often used for bags, trays, containers for fruit, vegetables,
eggs and meat, bottles for soft drinks and dairy products, and blister foils for fruit and vegetables.


2) Plastics made from petrochemicals:
These are the plastic made from petrochemicals with biodegradable additives which enhance biodegradation.
Biodegradable additives are additives that enhance the biodegradation of the polymers by allowing microorganisms to utilize the carbon within the polymer chain itself.

Applications of plastics made from petrochemicals :

The Petrochemicals & Plastics Sector provides a wide spectrum of petrochemical products, including synthetic resins typified by polyethylene and polypropylene, synthetic rubber, organic chemicals such as propylene oxide, and elastomers and other high-performance resins
