Basic Quiz – 29 September 2026 | Economy

Answer: (a)

Explanation:

Statement I is correct. Lithium-ion battery demand is rising rapidly with the expansion of electric mobility and energy storage. Inefficient recycling can therefore increase dependence on imported critical minerals.

Statement II is also correct and explains Statement I. Recycling allows materials contained in spent batteries to re-enter the production cycle. This substitutes part of the requirement for virgin mineral inputs and can reduce import dependence.

This is one of the central differences between a circular and linear economy. A linear model follows a take-make-dispose pathway, whereas a circular system attempts to retain material value through reuse, repair, refurbishment, recovery and recycling.

Answer: (c) Only three

Explanation:

Pair 1 is correctly matched. Automated Testing Stations (ATS) provide an institutional mechanism for testing vehicle fitness. Limited ATS availability can constrain the transition towards a formal vehicle scrappage ecosystem.

Pair 2 is correctly matched. Registered Vehicle Scrapping Facilities (RVSFs) are part of the formal infrastructure for dismantling and scrapping end-of-life vehicles.

Pair 3 is correctly matched. Recovered Carbon Black (rCB) is a higher-value material that can be obtained from waste-tyre recycling. The source identifies greater utilisation of rCB as an important circular-economy pathway.

Pair 4 is incorrect. Extended Producer Responsibility does not place responsibility exclusively on consumers. It extends responsibility for managing products after their useful life towards producers, thereby encouraging collection, recycling and environmentally sound waste management.

Answer: (c)

Explanation:

EPR extends producer responsibility into the post-consumer stage. Depending on the applicable regulatory framework, this can involve obligations relating to collection, recycling or environmentally sound management of products after their useful life.

This supports circularity because producers cannot treat the sale of a product as the end of their responsibility.

Option (a) is incorrect because circularity seeks greater use of recovered and secondary materials rather than prohibiting them.

Option (b) is incorrect because EPR does not simply transfer the entire burden to urban local bodies.

Option (d) is incorrect because landfilling represents loss of recoverable material value and is contrary to the objective of keeping resources circulating in the economy.

Answer: (c) Only three

Explanation:

Activities 1, 2 and 3 are consistent with circular-economy principles.

Tyre retreading extends the useful life of an existing product and reduces demand for new material.

Recovery of valuable minerals from spent batteries returns materials to productive use and can reduce dependence on virgin mineral extraction.

Refurbishment extends the life of electronic products and delays their entry into the waste stream.

Activity 4 is inconsistent with circularity. Landfilling recoverable materials permanently removes their economic value from the productive cycle.

The circular-economy framework in the source is based on six Rs: Reduce, Reuse, Recycle, Refurbishment, Recover and Repairing.

Answer: (b) 1, 2 and 4 only

Explanation:

Statement 1 is correct. EV expansion has two relevant material consequences. Vehicles eventually become ELVs, while their lithium-ion batteries also reach end-of-life and require collection, refurbishment or recycling.

Statement 2 is correct. Unsafe informal recycling can cause pollution and health hazards. Inefficient material recovery can also lead to economic losses because valuable materials that could re-enter production are lost.

Statement 3 is incorrect. Downcycling generally converts a material into a product of lower quality or economic value. It therefore differs from high-value recycling, which attempts to preserve greater material value.

Statement 4 is correct. Formalising informal recyclers through training, recognition, technical assistance and integration into regulated recycling systems is among the measures identified for strengthening circularity.
