When a plant, animal or insect dies it
breaks into tiny pieces and eventually, these small pieces become part of the
soil. This process is known as decomposition.
It is a process to break down (organic
matter) or to be broken down physically and chemically by bacterial or fungal
action. The process is a part of the nutrient cycle and is essential for
recycling the finite matter that occupies physical space in the biosphere.
The substance that should be disposed
or the waste that we produce can be separated into two categories:
Biodegradable and Non-Biodegradable. Biodegradable is easy to decompose but
non-biodegradable is a lot more difficult.
Organisms that do this are known as
decomposers. The decomposers are bacteria, fungi, and some worms which break
down dead plants, animals, and insects. A dead body is actually part of its own
ecosystem. Decomposition starts minutes after the death of a living organism,
with a process named autolysis, or self-digestion.
How long does it take to decompose? Different
sources have different information on actual time various waste items take in
landfills to decompose.

Plastic products are very common in
our modern life Plastic waste is one of many types of wastes that take too long
to decompose. Normally, plastic items can take up to 1000 years to decompose in
landfills. But plastic bags we use in our everyday life take 10-1000 years to
decompose, while plastic bottles can take 450 years or more.
The increasing waste volume is a major
concern for mankind. The best way to deal with this problem is avoiding
products that generate waste materials that take more than a year to decompose
in landfills through a proactive design for recycling.
