Plastic is designed to be inert and stable so it is no surprise that it is slow to decompose
The conditions for plastic decomposition are usually limited to attack by ultraviolet light or heat which break down the bonds between the monomers and cause the large plastic object to shatter and reshatter until it becomes just an inert particulate.
Plastic decomposition under biological attack is limited as few bacteria find it "tasty" however as some bacteria will eat crude oils there is undoubtedly some species that can be raised that will feed on plastic.
As far as plastic decomposition in waste disposal sites, these facilities are designed to minimize decomposition to prevent methane generation. They are both dry and anaerobic. Eve sfoodstuffs (fruit and steaks) have been found preserved after several decades of burial.
Its man made source and made from non natural materials which are water proof, fungi resisitance and does not rot or break down under any circumstances.
It can over millions of years.

no plastic does not decompose
no but it breaks up into tiny pieces but does not decompose
The plastic bag will not decompose but it may clog up the toilet.
about 5oo years...
You mean decompose -- Plastic decompose in a long period of time depending on the type of plastic and the environmental condition to which it is exposed.
The amount of time that it takes for plastic wrap to decompose it dependent on its size and materials. However, on average it takes 500 years to decompose.
Yes.
Yes plastic do decompose. But they will take about 500 to do so. So we don't encourage to use plastic bags when we purchase our items in the supermarket. A better choice is to bring recycling bag , a recycling bag takes only a few years to decompose
Glass, plastic and metal will never decompose anywhere.

Since it is man made , plastic does not decompose as well as other materials like paper. To give you an example a plastic cup would take about 1 million years to decompose, whereas a paper cup would take only 40 or 50 years to decompose.
