Which among the following is a biodegradable polymer?
- PVC
- Freon
- Nylon
- PHBV
The Correct Option is D
Approach Solution - 1
- A biodegradable polymer is a polymer that can be decomposed by natural biological processes. These types of polymers break down into carbon dioxide, water, and biomass under the action of microorganisms.
- PVC (Polyvinyl Chloride): This is a synthetic polymer that is not biodegradable. It is used in applications like pipes and cables and does not decompose easily.
- Freon: This is a trade name for a group of chemical compounds used as refrigerants. They are not polymers and are not biodegradable.
- Nylon: A synthetic polymer used in fabrics and textiles. It is not biodegradable because it is resistant to biological breakdown.
- PHBV (Polyhydroxybutyrate-co-hydroxyvalerate): This is a biodegradable polyester. It is produced by certain bacteria and decomposes in the presence of microorganisms.
Approach Solution -2
PHBV (Polyhydroxybutyrate-co-hydroxyvalerate) is a biodegradable polymer. It is a type of biopolymer that is made from renewable resources and can be broken down by microorganisms in the environment, making it environmentally friendly.
- PVC (Polyvinyl chloride): This is a non-biodegradable polymer that does not break down easily in the environment.
- Freon: This is a type of chlorofluorocarbon (CFC), not a polymer, and it is not biodegradable.
- Nylon: This is also a non-biodegradable polymer and does not decompose easily in the environment.
Thus, the only biodegradable polymer in the options is PHBV (Option D).
