Cradle-to-cradle principles (often written cradle-to-cradle or C2C) describe a design framework for sustainable production that seeks to eliminate waste by keeping materials in closed loops. The aim is to create products and systems where materials repeatedly serve as biological nutrients or technical nutrients, rather than becoming refuse in landfills, and where energy and water are managed responsibly.

At the core are five categories: material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness. The framework emphasizes designing from the outset for safe, circular materials and for disassembly, so that products can be returned to the cycles of nature or industry after use.

The concept was popularized by William McDonough and Michael Braungart in the 2002 book Cradle to Cradle. It has since influenced corporate sustainability programs and inspired the Cradle to Cradle Products Innovation Institute, which offers a certification scheme evaluating products against the five categories.

Applications span textiles, packaging, furniture, and construction, with emphasis on safe materials, recyclability, energy efficiency, and water management. Critics note cost, practicality, and the challenge of achieving full circularity across complex supply chains.

Cradle-to-cradle is closely associated with the broader circular economy and green chemistry movements, offering a proactive alternative to cradle-to-grave approaches and encouraging systemic redesign of products and production networks.
