What are the chemicals that are used to convert non biodegradable plastic to degradable plastic?

Have heard of chitosan. But you need some chemical compatibilizer in order to make a biodegradable blend in soil.
I think every plastic will need a different compatiblizer.

Example of biodegradable and non-biodegradable?
Some example of BIO-DEGRADABLE THINGS: paper, juice, chicken bones, clothes... anything that can be broken down by organisms NON BIO-DEGRADABLE THINGS: plastic toys, plastic bags, glass, steel, synthetic rubber.
Why can't plastics be decomposed by bacteria?
Plastic are made up of polymers. This polymers have various chemicals mixed in it that are not bio degradable. Normal bacterial activity is not enough to eat away long polymer chains making up any plastic. Also the chemicals used to make plastic bags degrade the quality of soil they are in hence they pollute the environment.
Why do people say plastic bags stay forever?
Plastic bags are not biodegradable.
Are biodegradable plastic bags stronger than regular plastic bags?
The biodegradability of a plastic is not strictly related to its tensile strength.However, it's a fair bet that a biodegradable bag is probably weaker than a "regular plastic" bag.
Can you put plastic in the vermicomposting pit?
no, we cannot put the plastic in the vemicomposting pit because plastic is a non biodegradable waste and non biodegradable waste cannot not be decomposed by earth worms or red worms.
Do degradable plastic bags create any environmental problems?
Some. types like Oxo-degradable, oxo-biodegradable, oxy-degradable, oxy-biodegradable, and degradable plastic(bags) are harmful.For they are merely plastic with a chemical additive.
How can you make non-biodegradable plastic degradable?
Blow it up.

How long does it take for degradable bags to degrade?
Biodegradable plastic bags can degrade in a few weeks.
Are plastic bottle biodegradable?
No. No plastic is biodegradable unless it's made from vegetable oil. Most plastic is made from fossil fuel oil.
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.
Difference between degradable and non degradable plastic?
All plastics are degradable and biodegradable, but normal plastic can take decades, or even hundreds of years. Oxo-biodegradable plastic (www.biodeg.org) will self-destruct if it gets into the open environment, leaving no harmful residues. It is made from a by-product of oil-refining which used to be wasted, so nobody is importing extra oil to make it. It can be recyled (www.biodeg.org/recycling.htm) and can be made from recycled plastic. During its service-life it has the same strength as normal plastic, and there is very little extra cost. It can be tested according to ASTM D6954. "Compostable" plastic is up to 400% more expensive, and is not suitable for weight-bearing packaging unless mixed with oil-based plastic. It will not readily degrade in the open environment, and emits methane deep in landfill. The composting Standards(eg ASTM D6400) require it to convert into CO2 gas within 180 days, so it contributes to climate change but does not improve the soil.
Are plastic plates biodegradable?
no because plastic isn't biodegradable.
Is biodegradable plastic are costly?
Yes! The issue is distinguishing between all plastics that claim biodegradable. ASTM Defines biodegradable plastic as: a degradable plastic in which thedegradation results from the action of naturally-occurringmicroorganisms (microbes) such as bacteria, fungi, and algae. There are mainly 3 categories currently offered in the market today. 1)Commercially Compostable, 2) Oxo-degradable, 3) Biodegradable plastics. 1) Compostable plastics (generally PLA-plastic derived from corn) say they are biodegradable, but it takes 140 degrees of sustained heat to break down the plastic in order to make it biodegradable or consumable by microbes in the commercial compost facility. (*NOTE-PLA is NOT compostable in a home compost environment, and contaminates the recycle stream...) 2) Oxo-degradable plastics are created by adding salts and heavy metals into the regular plastic, to create oxidization (breaks down in presence of oxygen) which in turn will fragment the plastic into small pieces. (*NOTE-Oxo-degradable should be thought of as fragmentable plastic and not biodegradable as their has been no scientific data to prove microbial consumption, also an obvious contaminate to recycling) 3) Biodegradable plastic follows the ASTM definition as consumable by microbes in and of itself, without the need of any heat or other mechanical change necessary. These plastics are created by the addition of organic materials which are highly desirable for microbes to consume. Microbes emit enzymes to digest the additive, and in turn unlock the plastic carbon chain within the plastic molecule to be additional food. This process is continued until the whole plastic item is consumed. Any food item or other organic material is processed by nature in the identical fashion. The esnoplastics do NOT contaminate the recycle stream because the organic materials do not chemically bond or alter plastic)
Are plastic shopping bags bio degradable?
Some of the plastic bags are made of bio degradable materials like superplast plastic factory
Is there a sign on plastic bags to say there are biodegradable?
no there is not because a plastic bag is not biodegradable
How long non biodegradable substances last?
Examples are plastics, metal and glass. Dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials.
