Subsequently, question is, how long does it take things to decompose? According to our research the following is the estimated time for some everyday items that are all around us to decompose in landfill sites: Plastic bottles: 70-450 years. Plastic bag: 500-1000 years. Tin can: around 50 years.
Besides, how do plastic bags decompose?
The only real way to break down plastic is through photodegradation. This kind of decomposition requires sunlight, not bacteria. When UV rays strike plastic, they break the bonds holding the long molecular chain together. Over time, this can turn a big piece of plastic into lots of little pieces.
Why do plastics not decompose?
To explain in a very simple way, plastics don't decompose in soil because, The decomposition process happens because of the bacterias in the soil. When we talk about food, these bacterias have enough energy to break the food into pieces. But in plastics, bacteria don't have enough energy to break the bonds in plastic.
