Step 1: Review of SWM Rules 2016.
The Solid Waste Management Rules, 2016 expanded coverage to urban, rural, and industrial areas. It clearly defines different categories of waste.
Step 2: Analyze options.
- (A) Correct → Dry waste means non-biodegradable waste such as plastics, paper, metals, glass, and also excludes biodegradable and inert waste. ✓
- (B) Wrong → Combustible waste refers to dry wastes with high calorific value that can be used for energy recovery. It does not include biodegradable or hazardous wastes with such a low threshold of 800 kcal/kg. ✗
- (C) Correct → Domestic hazardous waste includes household hazardous items like expired medicines, used CFLs (containing mercury), discarded paint drums, sprays, pesticide cans. ✓
- (D) Wrong → Biodegradable waste = organic matter degradable by microbes. The statement wrongly says "inorganic material that cannot be degraded," which is incorrect. ✗
Step 3: Conclusion.
Hence, correct statements are (A) and (C).
Final Answer: \[ \boxed{\text{(A) and (C)}} \]
Match the various types of impurities present in water in Group I with the appropriate water treatment process given in Group II.
\[\begin{array}{|c|c|} \hline \textbf{Group I} & \textbf{Group II} \\ \hline \text{P: Fine suspended matter} & \text{1: Aeration} \\ \hline \text{Q: Pathogenic bacteria} & \text{2: Plain sedimentation} \\ \hline \text{R: Color, odour and taste} & \text{3: Sedimentation with coagulation} \\ \hline \text{S: Floating matter as leaves} & \text{4: Screening} \\ \hline & \text{5: Disinfection} \\ \hline \end{array}\]
| Type of House | Percentage of Households | Equivalent volume of compacted solid waste generated/ household/ day |
| LIG | 30% | 0.10 \(m^3\) |
| MIG | 60% | 0.15 \(m^3\) |
| HIG | 10% | 0.20 \(m^3\) |
