Correct Option
The correct option isWaste contains recyclable materials that can be reprocessed.
Explanation
Resource recovery is a systematic process in waste management that involves separating and extracting useful materials or energy from solid waste. It is a critical element of the circular economy, aiming to minimize waste disposal in landfills by reintroducing recovered materials into the economic cycle.
Option Analysis
- All waste is hazardous and must be incinerated. is Incorrect: Not all waste is hazardous; municipal solid waste consists largely of non-hazardous organic and inorganic materials. Additionally, incineration is a specific treatment method for volume reduction and energy generation, not a mandatory requirement for all waste types.
- Waste contains recyclable materials that can be reprocessed. is Correct: This statement captures the essence of resource recovery. It acknowledges that waste is not merely refuse but a source of secondary raw materials (such as metals, paper, and plastics) that can be reclaimed and reprocessed for new manufacturing.
- Waste generation is unavoidable and unmanageable. is Incorrect: Modern waste management operates on the principle that waste generation can be minimized through the "3Rs" (Reduce, Reuse, Recycle). Considering waste as unmanageable ignores established scientific methods for treatment and disposal.
- Landfills are the only solution for waste disposal. is Incorrect: According to the waste management hierarchy, landfills are the least preferred option, reserved only for inert residues that cannot be recycled or recovered. Relying solely on landfills is unsustainable due to environmental risks like leachate and methane emissions.
Key Takeaway: Resource recovery transforms waste management from simple disposal to value extraction, prioritizing the reclamation of recyclable materials and energy over landfilling.
