Advantage and disadvantage of bio-based polymers.

Advantages	Disadvantages
Carbon dioxide levels can be decreased by bio-based polymers	Procedure of disposal must be precise
Emission of greenhouse gas levels can be reduced	Biopolymers comprises of some metal particles
Polymers are broken down by bacteria which occurs naturally	Recycling amount may be educed
Amount of waste can be reduced	Protection is required because they contain toxins
It can be mixed along with the olden forms	Limited lifetime for the bio-based polymers
It is chemical free and cost effective	Compared to oil-based polymer it is cost extensive
Only less energy is required	Elimination of hard substance takes place slowly
In the decomposition dangerous items are not exposed	Pollution in ocean and sea cannot be resolved by these biopolymers
They have good chemical, physical and mechanical properties	Low physical and mechanical resistance
