William McDonough, FAIA, Int. FRIBA, is a trained architect, yet works at scales from the global to the molecular. He advises leaders worldwide through McDonough Innovation; and is active with William McDonough + Partners, architects; as well as MBDC, a Cradle to Cradle® consulting firm. In 1995, McDonough and the chemists at MBDC worked with DesignTex to create the world’s first biological nutrient fabric. Climatex LifeCycle uses only rapidly renewable, natural materials and non-toxic dyes. Water leaves the factory as clean or cleaner than the potable water coming in. Production costs were lowered, waste disposal costs drastically reduced, and community relations improved. Shaw Contract Group also engaged McDonough and the MBDC team to design the world’s first PVC-free technical nutrient carpet tile to be endlessly recycled and reused as a product of service. Today, over 60% of the company’s sales come from Cradle to Cradle Certified™ products and Shaw reclaims 100 million pounds of carpet annually. These projects laid the foundation for the 2002 book co-authored by McDonough, Cradle to Cradle: Remaking the Way We Make Things, which introduced the concepts of biological and technical cycles and provides a coherent framework for restorative and regenerative systems. These concepts have not only inspired the continued expansion and selection of Cradle to Cradle Certified products, but also all of McDonough’s work including Park 20|20 in the Netherlands where buildings are “material banks” designed for disassembly and as assets for future generations.
