Does plastic take 100 years to decompose?
Plastics can take anywhere from 20 to 500 years to decompose, depending on the material and structure. Additionally, how fast a plastic breaks down depends on sunlight exposure. Like our skin, plastics absorb ultraviolet (UV) radiation from the sun, which breaks down the molecules.
That is not to say that plastics can't breakdown, they do, but it takes a long time; plastic bottles take up to 450 years to decompose in landﬁll.
Plastic does not decompose. This means that all plastic that has ever been produced and has ended up in the environment is still present there in one form or another. Plastic production is booming since the 1950s.
The reason for the slow degradation is a simple one. These materials do not exist in nature, and therefore, there are no naturally occurring organisms that can break them down effectively or at all. The chemical bonds in plastic materials are not accessible or “familiar” to bacteria in nature.
Normally, plastic items take up to 1000 years to decompose in landfills. But plastic bags we use in our everyday life take 10-20 years to decompose, while plastic bottles take 450 years. Just in the United States alone, every year more than 18 billion disposable diapers are thrown away.
Well, according to some researchers, they estimate that due to the PET used in objects like plastic bags, plastic water bottles and plastic straws, it could take upwards of 450 years to decompose. Yep, a rather frightening estimation.
It takes 1,000 years for a plastic bag to degrade in a landfill. Unfortunately, the bags don't break down completely but instead photo-degrade, becoming microplastics that absorb toxins and continue to pollute the environment.
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.

Plastic rubbish will outweigh fish in the oceans by 2050 unless the world takes drastic action to recycle the material, a report has warned on the opening day of the World Economic Forum (WEF) in the Swiss ski resort of Davos.
Can plastic last a million years?
Fossilised plastic preserved in rock will be around for millions of years as a reminder of pollution, leading academic says.
