Design thinking is an innovative problem-solving approach that emphasizes empathy, collaboration, and iterative processes to generate creative solutions. It revolves around understanding user needs, exploring multiple perspectives, and iteratively refining ideas through prototyping and testing. Design thinking focuses on human-centered design, putting people at the core of the design process to create meaningful and effective solutions. Circular design thinking, on the other hand, takes the principles of design thinking and applies them within the context of a circular economy. In a circular economy, the goal is to minimize waste, keep materials in use, and regenerate natural systems. Circular design thinking involves designing products, systems, and services that are regenerative, waste-free, and restorative by nature. The evolution from design thinking to circular design thinking occurs when designers start considering the entire lifecycle of a product and the impact it has on the environment. They seek to design products that are not only functional and user-centric but also sustainable and circular in nature. This shift involves reimagining the design process to incorporate principles of sustainability and circularity. Circular design thinking encourages designers to think beyond linear models of production and consumption and consider the entire lifecycle of a product, including sourcing, manufacturing, use, and end-of-life. They strive to design products that can be easily disassembled, repaired, and recycled, thereby minimizing waste and extending the lifespan of materials. Ellen MacArthur, a renowned sailor and environmental advocate, has played a pivotal role in promoting circular design thinking through the Ellen MacArthur Foundation. She has raised awareness about the importance of transitioning from a linear economy to a circular economy that aims to keep materials in use for as long as possible. Circular design thinking involves considering the environmental impact of materials, designing for durability and adaptability, and prioritizing the use of renewable resources. It also encourages collaboration among stakeholders from various disciplines to foster innovation and systemic change. By adopting circular design thinking, designers can contribute to a more sustainable future by minimizing resource depletion, reducing waste, and promoting the efficient use of materials and energy. They can create products and systems that are not only environmentally friendly but also economically viable and socially responsible. In conclusion, design thinking forms the foundation for circular design thinking. It is through the integration of circular principles that designers can create innovative solutions that prioritize sustainability, resource efficiency, and the well-being of both people and the planet. Circular design thinking represents a shift towards more holistic and regenerative design practices, aligning with the principles of a circular economy.
