Student Guide (IB Design Technology)
Simple Explanation: This study shows that by looking closely at what electronic waste is made of and how it's handled, we can find ways to turn old electronics into something more valuable, not just recycle them.
Why This Matters: Understanding upcycling potential is crucial for designing products that are not only functional but also contribute to a sustainable, circular economy by minimizing waste and maximizing resource value.
Critical Thinking: To what extent can the identified upcycling technologies be scaled for industrial application, and what are the economic barriers to their widespread adoption?
