Which form of recycling returns a product into the same product?

Which form of recycling returns a product into the same product?

• A. Open-loop Recycling
• B. Closed-loop Recycling
• C. Compost
• D. Leachate

Answer: (B)

The idea being tested is whether recycled material is remanufactured into the same product, rather than into something different. This is closed-loop recycling, where the material quality is maintained enough to be used again in the same item—for example, aluminum cans becoming new aluminum cans or glass bottles becoming new glass bottles. In practice, these materials can cycle back into the same product many times with minimal degradation. Open-loop recycling, by contrast, recycles material into a different, often lower-grade product (like plastic bottles turned into fibers or Park Benches), so the end product isn’t the same item. Compost involves breaking down organic matter into soil-like material, not producing another finished product of the same kind. Leachate is the liquid that drains from waste and is a pollution concern, not a form of recycling.
