Open-loop recycling is best described as turning waste into a new product with altered properties. Which option matches this definition?

• A. Closed-loop recycling
• B. Primary recycling
• C. Open-loop recycling
• D. Secondary recycling

Answer: (C)

Open-loop recycling is defined by taking waste and turning it into a product that is different from the original, often with changed properties or performance. This shift to a new use or form is what sets it apart from other recycling types. For example, plastic bottles can be melted down and made into carpeting fibers or plastic lumber, so the material’s application and properties are altered from the initial bottle. In contrast, closed-loop recycling aims to produce the same item again (the material returns to its original form), while primary recycling generally implies reusing material in the same type of product with little or no change, and secondary recycling can be more broad and often involves creating a different or lower-grade product. Because the description emphasizes transforming waste into a new product with altered properties, the concept that fits best is open-loop recycling.
