Question

What is the new concept of waste management ?

• A. Reuse
• B. Recycle
• C. Reduce
• D. All of these

Hint:

Remember the hierarchy of the 3Rs: Reduce > Reuse > Recycle. The most effective way to manage waste is to not create it in the first place (Reduce). Recycling is the last resort among the three.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Modern waste management is guided by a principle known as the "3Rs of Waste Management". This concept provides a hierarchy for managing waste in the most environmentally friendly way.

Step 2: Detailed Explanation:
The 3Rs stand for: \[\begin{array}{rl} \bullet & \text{Reduce: This is the first and most important step. It means minimizing the amount of waste generated in the first place. For example, buying products with less packaging. } \\ \bullet & \text{Reuse: This is the second priority. It involves using items more than once instead of throwing them away after a single use. For example, using a reusable water bottle instead of disposable ones. } \\ \bullet & \text{Recycle: This is the third option. It is the process of converting waste materials into new materials and objects. For example, recycling paper, plastic, and glass. } \\ \end{array}\] Since all three concepts—Reduce, Reuse, and Recycle—are integral parts of the modern approach to waste management, the correct option is "All of these".

Step 3: Final Answer:
The new concept of waste management includes Reduce, Reuse, and Recycle.
