They may be composed of either bioplastics, which are plastics whose components are derived from renewable raw materials, or petroleum-based plastics. The use of bio-active compounds compounded with swelling agents ensures that, when combined with heat and moisture, they expand the plastic's molecular structure and allow the bio-active compounds to metabolise and neutralize the plastic. Biodegradation of plastics can be achieved by enabling microorganisms in the environment to metabolize the molecular structure of plastic films to produce an inert humus-like material that is less harmful to the environment.
Bioplastics (also called organic plastics) are a form of plastics derived from renewable biomass sources, such as vegetable oil, corn starch, pea starch or microbiota.
Degradation of petroleum-based biodegradable plastics may release of previously stored carbon as carbon dioxide. Materials such as polyhydroxyalkanoate (PHA) biopolymer are completely biodegradable. Fully biodegradable plastics are more expensive, partly because they are not widely enough produced to achieve large economies of scale.

What are biodegradable plastic bags made of?
plastic
Are bottles biodegradable?
No. No plastic is biodegradable unless it's made from vegetable oil. Most plastic is made from fossil fuel oil.
Are plastic beads biodegradeble?
no, plastic can never be considered a biodegradable waste because it cannot be made into simpler substances by the microorganisms
What are hefty bags made of?
Biodegradable plastic.
Are plastic plates biodegradable?
no because plastic isn't biodegradable.
What are most modern plastics made from?
No there are some plastic bags that are biodegradable
Is there a sign on plastic bags to say there are biodegradable?
no there is not because a plastic bag is not biodegradable
Are basketball biodegradable?
If the ball is made from a rubber based polymer, which I would assume it is due to elasticity, then it is NOT biodegradable.
How are biodegradable plastic made?
There are two types of biodegradable plastics: bioplastics and plastics made from petrochemicals. Bioplastics are made from renewable resources, like vegetable fats and oils, vegetable starch, or microbiota. Plastics made from petrochemicals are made by combining biodegradable additives which enhance biodegradation.
Is a crisp wrapper biogradable?
It depends on what kind of plastic it is,some yes some no
Are plastic shipping bags still being made?
Plastic shipping bags are still being made. Biodegradable plastic and degradable plastic bags are much friendlier to the environment than just regular plastic bags.
Why are plastic cups not biodegradable?
they are.
