Week 5: Biomimicry
Projects that are changing Products A few savvy manufacturers are beginning to look at na-

design problems This process, called Biomimicry, seeks to
harness the capabilities found in structures that have
evolved in the plants and animals around us to make,
stronger and more sustainable products for the future.

Week 6: Sustainability Sustainability is used to refer to a range of different
concepts and practices. But it usually makes us think

Reduce We must mend broken products instead of throwing them away.
Reuse We should decrease the amount of finite materials that we use.
Recycle We should decide whether we need products before we buy them.
Refuse We should think of another use for a product before we throw it away.
Repair We should decide not to buy products that harm the environment.
Rethink We should make sure that products are converted back to their basic materials and then remade into new products.
