What material will never decompose?

Some materials, such as glass and styrofoam, do not decompose at all. This means that if they are not recycled, they will stay in the environment indefinitely. This can be a major problem, as these materials can take up valuable space in landfills and can cause pollution if they are not disposed of properly.

Why plastic Cannot be decomposed?

The enzymes in the microorganisms that break down biodegradeable materials don't recognize the bonds that hold polymers together. Eventually, the polymers in plastic waste may break down, perhaps after hundreds of thousands of years. But when it takes such a long time, the damage is already done to the environment.

Can plastic decompose in 1000 years?
