Question

Which of the following is a non-biodegradable polymer?

• A. PHB
• B. PGA
• C. LDPE
• D. PHBV

Hint:

LDPE is a non-biodegradable polymer that persists in the environment, unlike biodegradable polymers such as PHB and PGA.

Answer 1

The Correct Option is C

Step 1: Understand the biodegradability of polymers.
Low-Density Polyethylene (LDPE) is a widely used non-biodegradable polymer.
PHB (Polyhydroxybutyrate) and PHBV (Polyhydroxybutyrate-co-Polyhydroxyvalerate) are biodegradable, and PGA (Polyglycolic acid) is also biodegradable.
Step 2: Identify the non-biodegradable polymer.
LDPE is non-biodegradable and remains in the environment for a long time.
