Waste segregation at source – UGC NET Question

Statements A, C, D and E are correct because source segregation improves material quality, household sorting reduces contamination, informal workers enhance recovery, and awareness plus system design keep segregation going. Statement B is false since mixing waste reduces the quality of recyclables and makes processing harder. Statement F is false because proper segregation helps waste-to-energy plants by removing wet or inert materials that lower calorific value. Therefore, the combination A, C, D and E only is correct.

Option A:
Option A is incorrect as it omits D and E, thereby ignoring the significant roles of informal workers and supportive systems in making segregation effective and sustainable.

Option B:
Option B is incorrect because it leaves out E and still fails to mention the importance of public awareness. It also does not include all relevant correct statements about actors and systems involved.

Option C:
Option C is correct since it recognises technical, behavioural and institutional aspects of segregation while rejecting claims that mixing improves efficiency or that segregation is irrelevant for waste-to-energy facilities.

Option D:
Option D is incorrect as it includes F, which wrongly dismisses the relevance of segregation for energy recovery, and it omits A, which is the core statement about what segregation does.
