Student Guide (IB Design Technology)

Simple Explanation: We can use leftover plant stuff from farms, like straw or husks, to make building materials, which is good for the environment because it reduces waste and uses fewer new resources.

Why This Matters: Using farm waste for building materials helps create a circular economy, meaning we reuse and recycle more, which is better for the planet and can lead to innovative new products.

Critical Thinking: Beyond environmental benefits, what are the economic and social implications of widespread adoption of agricultural residue-based building materials?
