Let’s stop treating our resources disdainfully
Our task is to design products in such a way that they can be completely and without loss of quality returned to biological or technical cycles after use. Without waste.
The philosophy of Cradle to Cradle (C2C) arises at a time characterized by ecological and social challenges. Developed by the German chemist Michael Braungart and the American architect William McDonough, this concept represents a radical shift in our understanding of production and consumption.
Melting Away Waste
At its core, Cradle to Cradle is about eliminating waste. This means designing products so that after their use, they are either completely biodegradable and can thus be returned as nutrients to the natural cycle, or they remain within closed industrial cycles and can be reused without loss of quality. This is often referred to as the biological and technical cycles.
Biological Cycle: Products belonging to this cycle consist of materials that can be returned to nature, such as cotton or biodegradable plastics. A garment made of pure cotton can be composted after use to provide nutrients for new plants.
Technical Cycle: This includes materials that can be recycled repeatedly without loss of quality, such as aluminum or certain plastics. An example is an aluminum casing that can be melted down at the end of its life cycle and used to create new products.
Designing for the Future: A central element of the Cradle to Cradle principle is design for disassembly. Products are designed to be easily taken apart into their components to facilitate recycling. This requires careful material selection and thoughtful construction.
Another important criterion is the safety of the materials. This means that all materials used must be safe for humans and the environment. Toxic substances are a no-go, as they would contaminate the cycle.
Energy and Water Management: The C2C concept also emphasizes the use of renewable energy sources and efficient water usage. Production processes should rely on solar, wind, or other sustainable energy sources and use water in such a way that it can be returned to the cycle in a clean form after use.
Certification and Implementation: To ensure that products are truly manufactured according to the principles of Cradle to Cradle, there is a certification system. This evaluates products in various categories, such as material health, circularity, use of renewable energy, water management, and social fairness.
Practical Examples: Many companies have begun integrating Cradle to Cradle into their production processes. Today, there are biodegradable t-shirts, fully recyclable carpet tiles, and even houses built according to C2C principles.
Cradle to Cradle is more than just a sustainability concept. It is a vision for a world where people live and work in harmony with nature. It challenges us to radically rethink and improve our production methods to ensure a livable future for generations to come. The challenge lies in broadly implementing these principles to bring about real change. It is up to us to consistently pursue this path and tap into the creative possibilities that Cradle to Cradle offers.
