Question

The following table gives various components of Municipal Solid Waste (MSW) and a list of treatment/separation techniques. \[ \begin{array}{|l|l|} \hline Component of MSW & Treatment/separation technique
\hline P - \text{Ferrous metals} & \text{i - Incineration}
Q - \text{Aluminum and copper} & \text{ii - Rapid composting}
R - \text{Food waste} & \text{iii - Eddy current separator}
S - \text{Cardboard} & \text{iv - Magnetic separator}
\hline \end{array} \] The CORRECT match is

• A. P-iii, Q-iv, R-i, S-ii
• B. P-iv, Q-iii, R-ii, S-i
• C. P-iii, Q-iv, R-ii, S-i
• D. P-iv, Q-iii, R-i, S-ii

Hint:

Proper waste management involves selecting the appropriate treatment method based on the physical and chemical properties of the waste material.

Answer 1

The Correct Option is B

Step 1: Evaluating the correct matches for each component: Ferrous metals (P): These are best separated using magnetic separators, hence match with option iv. Aluminum and copper (Q): These non-ferrous metals can be separated effectively using eddy current separators, hence match with option iii. Food waste (R): It is typically treated using rapid composting, hence match with option ii. Cardboard (S): It is usually disposed of or treated using incineration, hence match with option i. Step 2: From the analysis above, the correct matching is: \[ P \rightarrow iv, \quad Q \rightarrow iii, \quad R \rightarrow ii, \quad S \rightarrow i \] Conclusion: The correct answer is option (B).
