Bio design combines biology, design, and sustainability to create eco-friendly solutions. It includes practices like biomimicry, which uses nature to inspire designs, such as energy-efficient buildings based on termite mounds. Biofabrication involves using living organisms for material production, reducing waste and reliance on non-renewable resources, like 3D printing with bio-based inks. Sustainable product design focuses on environmentally friendly items throughout their lifecycle, using biodegradable materials and circular design for reuse and recycling. Overall, bio design aims for a sustainable future by merging biological insights with design processes.
