De la cuna a la cuna (C2C) is a design philosophy that models human industry on nature’s processes. It views materials as “nutrients” circulating in bucle cerrado systems. The framework distinguishes between two cycles: the biological cycle, for biodegradable materials that can safely return to the soil, and the technical cycle, for materials that are continuously reused or upcycled in industrial processes without losing quality.

The Cradle-to-Cradle framework fundamentally challenges the traditional “de la cuna a la tumba” industrial model, which results in a one-way flow of materials to landfills or incinerators. C2C proposes a economía circular where waste is eliminated by design. This is achieved by meticulously selecting materials based on their human and environmental health characteristics, avoiding toxic substances altogether. Products are designed for disassembly, allowing their components to be easily separated and returned to their respective cycles at the end of their use phase.

In the biological cycle, materials like natural fibers, certain bioplastics, and organic pigments are designed to be consumed by microorganisms and return to the biosphere as biological nutrients, enriching the soil. In the technical cycle, synthetic materials like polymers, metals, and alloys are designed to be high-quality “technical nutrients.” These materials are intended to be perpetually upcycled into new products of the same or higher quality, never becoming waste. This contrasts with conventional recycling, which often results in downcycling, where the material quality degrades with each cycle.

Implementing C2C requires a shift in thinking from simply being “less bad” (eco-efficiency) to being “more good” (eco-effectiveness). It encourages innovation in material science, product design, and business models. The C2C Certified™ Products Program provides a third-party verification system that assesses products based on material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness.
