In their 2002 book Cradle to Cradle: Remaking the Way We Make Things, architect William McDonough and chemist Michael Braungart presented an integration of design and science that provides enduring benefits for society from safe materials, water and energy in circular economies and eliminates the concept of waste.
The book put forward a design framework characterized by three principles derived from nature:
Everything is a resource for something else. In nature, the “waste” of one system becomes food for another. Everything can be designed to be disassembled and safely returned to the soil as biological nutrients, or re-utilized as high quality materials for new products as technical nutrients without contamination.
Use clean and renewable energy. Living things thrive on the energy of current solar income. Similarly, human constructs can utilize clean and renewable energy in many forms—such as solar, wind, geothermal, gravitational energy and other energy systems being developed today—thereby capitalizing on these abundant resources while supporting human and environmental health.
Celebrate diversity. Around the world, geology, hydrology, photosynthesis and nutrient cycling, adapted to locale, yield an astonishing diversity of natural and cultural life. Designs that respond to the challenges and opportunities offered by each place fit elegantly and effectively into their own niches.
Rather than seeking to minimize the harm we inflict, Cradle to Cradle reframes design as a positive, regenerative force—one that creates footprints to delight in, not lament. This paradigm shift reveals opportunities to improve quality, increase value and spur innovation. It inspires us to constantly seek improvement in our designs, and to share our discoveries with others.
Cradle to Cradle Certified™ Products
In 2005, MBDC created the Cradle to Cradle Certified Products Program to recognize high levels of sustainability achieved by its clients and to inspire others to optimize their products and “rethink the way they make things.” In 2010, MBDC donated to the Cradle to Cradle Products Innovation Institute an exclusive license for the certification program and methodology, and the Institute now administers the program and manages the Product Standard as a third-party, nonprofit organization.
