Designing cradle-to-cradle products: a reality check

Abstract

The cradle-to-cradle (C2C) concept of McDonough and Braungart, which has a strong emphasis on materials strategy, gives a vision of a sustainable future, inspired by nature. Their guilt-free approach has enthused many new people, drawing them into the field of sustainability. However, the question of when and how the C2C concept can be applied successfully in business is still being debated. This paper takes a look at the applicability of the C2C concept in day-to-day product development in a business setting. Based on student design projects for several multinationals, the strengths and weaknesses of the concept are evaluated. In particular, the compatibility of C2C and life cycle assessment (LCA) is addressed. The authors conclude that LCA and C2C can and should be used as complementary tools. C2C's main value is that it triggers many questions about current business practice. Designers may play an interesting role in ‘paving the way’ for the restructuring of business operations according to C2C: through design pilots they can show how C2C could make business sense. LCA should be used to assess whether such pilots still make environmental sense if implemented in today's ‘real world’.
