Question

The term "circular economy" in chemical technology refers to:

• A. Linear production and disposal
• B. Increasing single-use plastics
• C. Maximizing waste generation
• D. Reusing and recycling materials

Hint:

A circular economy in chemical tech aims to close the loop — reducing waste by reusing, recycling, and recovering materials wherever possible.

Answer 1

The Correct Option is D

The concept of a circular economy is a sustainability-oriented approach that contrasts with the traditional linear economy model of "take, make, dispose."
In chemical technology, a circular economy emphasizes the continuous use of resources by:
- Designing products for longer life, reusability, and recyclability
- Reducing raw material usage and minimizing waste
- Promoting closed-loop systems where materials are reused and recycled rather than discarded
For example, instead of using single-use plastics that contribute to pollution, a circular model would involve developing biodegradable polymers, recycling plastics, or converting waste into useful materials (like fuels or new chemicals).
Incorrect options:
- (1) Linear production and disposal is the opposite of a circular system.
- (2) Increasing single-use plastics contradicts the waste reduction goal.
- (3) Maximizing waste generation goes directly against circular economy principles.
Thus, the correct interpretation of "circular economy" is reusing and recycling materials.
