The following table gives various components of Municipal Solid Waste (MSW) and a list of treatment/separation techniques.
Component of MSW
P - Ferrous metals
Q - Aluminum and copper
R - Food waste
S - Cardboard
Treatment/separation technique
i - Incineration
ii - Rapid composting
iii - Eddy current separator
iv - Magnetic separator
The CORRECT match is
- P-iii, Q-iv, R-i, S-ii
- P-iv, Q-iii, R-ii, S-i
- P-iii, Q-iv, R-ii, S-i
- P-iv, Q-iii, R-i, S-ii
Correct answer: P-iv, Q-iii, R-ii, S-i
Solution
The correct option matches each component of Municipal Solid Waste with the most effective treatment or separation technique: ferrous metals (P) are best separated using a magnetic separator (iv), aluminum and copper (Q) are effectively separated with an eddy current separator (iii), food waste (R) is suited for rapid composting (ii), and cardboard (S) can be incinerated (i) for energy recovery.
