Which of the following defines "upcycling"?

The definition of "upcycling" emphasizes the process of transforming waste materials into new products that possess a higher value. This approach not only helps reduce waste but also encourages creativity and innovation by finding new uses for items that might otherwise be discarded. By enhancing the quality or utility of these materials, upcycling contributes to sustainability practices and promotes a circular economy.

The other options describe processes that do not align with the concept of upcycling. Discarding waste materials entirely negates the principle of reusing or repurposing them. Transforming waste materials into new products with lesser value contradicts the essence of upcycling, which is all about elevating existing materials. Lastly, reprocessing materials into the same products refers to recycling instead of upcycling, as it does not involve creating new and higher-value items. Understanding these distinctions helps clarify why transforming waste into higher-value products is the defining characteristic of upcycling.
