Polymer scientists work on all kinds of plastics, including bacteria-degradable ones.
Any substance that can be decomposed by bacterial action is referred to as biodegradable. For example, plastic is not biodegradable but paper is a biodegradable material.

Everything is related to chemistry, and especially man made materials such as plastics. To keep it simple, "organics" are similar in makeup in that they are basically made of carbon atoms. How these chains are oriented (length, branching, etc.) has everything to do with their molecular properties. You can't make plastic without organic chemistry.
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.
The bacteria that is known to break down plastic is called Ideonella sakaiensis. It was discovered in Japan in 2016 and has the ability to digest PET (polyethylene terephthalate), a type of plastic commonly used in bottles.
Chemistry
Something that can't be decomposed by nature, such as plastic
They are hard and can not be melted on heating they become decomposed as Bakelite.
that can use again are called dergadable plastics
Any substance that can be decomposed by bacterial action is referred to as biodegradable. For example, plastic is not biodegradable but paper is a biodegradable material.
If something is biodegradable it can be decomposed by bacteria or by living organisms. Something that is photodegradable can be decomposed by light or the sunBiodegradable means being able to be broken down into more basic components by fungi, bacteria or other simple organisms. Most chemicals are biodegradable but it takes different amount of time to break down, for example a piece of bread will break down rather quickly, and a piece of plastic will take decades and beyond.Photodegradable objects are substances that can be broken down into their simpler forms by the action of ultraviolet rays present in the sunlight. Plastic, for example, is photodegradable.Tags:Biodegradabilitybiodegr.
Plastic materials (with some exceptions) are chemical substances.

Biodegradable means that something is capable of being decomposed by bacteria or other living organisms. A paper wrapper for a sandwich is biodegradable, but a plastic box is not. Bury the plastic box, dig it up a year later, it is still there. The paper wrapper would have degraded to humus (soil).
bio degradeable obgects like paper cardboard and food. and glass and metal and plastic
They helps because they is good in the people, for the chemistry. When the same but no chemistry, is not plastic biodegradable but, otherwise good for them which why they helps. Not the biology!
