Circular Economy
Using the Circular Economy model, explain how the technical cycle aims to minimize waste and extend the lifespan of manufactured products.
Technical cycle deals with man-made, durable products (e.g., metals, plastics, electronics).
Products are designed to be reused, repaired, remanufactured, or recycled, instead of following a linear "take–make–dispose" model.
The goal is to retain value of materials and reduce the need for virgin resource extraction.
Example: Old smartphones being collected, refurbished, and resold instead of discarded.
