Environmental Science. Jul 31, Plants,, animal bodies all consumed by some form of bacteria and get decomposed. Explanation: But plastic materials can not be consumed by such earth bacteria. Jul 30, Explanation: Plastic is made from petroleum, a product of oil, using heat and a catalyst to change the propylene into polypropylene, a substance not found in nature.

Below is the list of conventional fossil-based plastics and their properties and applications —. These plastics are made from fossil based polymers and combined with specific additives in order to follow a similar end-of-life as bioplastics i. However, these additives will enable only fragmentation of the plastics and not degradation, which results in very small fragments that still remains in the environment.
Plastics are used because they are easy and cheap to make and they can last a long time. Unfortunately these same useful qualities can make plastic a huge pollution problem. To biodegrade, organic materials require air, water, light or a combination of these elements so microorganisms can do their job.
Remove any or all of these elements, and biodegradation can be slowed dramatically. Air, water and light would cause it to biodegrade. Another example … remember the Dead Sea Scrolls? Made from parchment and papyrus, both materials that can biodegrade, the scrolls survived two millennia in caves. Once removed from the caves, they began to biodegrade quickly.
