IB Design Technology 8.3.2 Principles of Sustainable Design Notes

Cyclic: Closing the Loop with Renewable Resources

Have you ever thought about what happens to a product when it reaches the end of its life? The Cyclic principle encourages designers to use materials that can either biodegrade naturally or be recycled indefinitely without degrading in quality. This ensures that products don’t become waste but instead re-enter the natural or industrial cycle.

For instance, imagine designing a backpack. Instead of using synthetic fabrics that take centuries to decompose, you could opt for organic cotton or recycled polyester. When the backpack wears out, its materials could be repurposed into new products or safely decompose.

Solar: Powering Production with Renewable Energy

Picture a world where every product is made using clean, renewable energy. The Solar principle focuses on reducing reliance on fossil fuels by using energy sources like solar, wind, or hydroelectric power for manufacturing and operation.

Consider a factory producing solar panels. If the factory itself is powered by solar energy, it creates a virtuous cycle, producing renewable energy products using renewable energy.

Safe: Eliminating Toxicity in Products and Waste

Have you ever noticed the strong smell of paint or glue? That odor often comes from harmful chemicals that can affect both human health and the environment. The Safe principle ensures that products are free from toxic materials and that their production doesn’t generate harmful by-products.

For example, traditional paints often contain volatile organic compounds (VOCs) that release harmful fumes. Sustainable alternatives, like water-based or plant-based paints, eliminate these risks, making them safer for both users and the environment.
