Basic concepts and principles

The 5R principles: Reduce, Reuse, Recycle, Repair, Recover

The circular economy is based on the 5R principles, which serve as a guide for sustainable practices:

• Reduce: Minimize the consumption of resources and waste through more efficient production and consumption patterns.
• Reuse: Use products multiple times before disposing of them to extend their lifespan.
• Recycle: Separate and recycle materials correctly to return raw materials to the production cycle.
• Repair: Repair broken items instead of throwing them away to extend their useful life and prevent waste.
• Recover: Recover energy and materials from non-recyclable waste to maximize its value and reduce environmental impact.

These principles help to optimize the flow of materials in the economy and minimize environmental impact.

Economic benefits and business models

The circular economy offers numerous economic benefits, including cost savings through resource efficiency and new business opportunities through innovative business models. Examples of such models include

• Product-as-a-Service: companies retain ownership of their products and lend them to customers, who only pay for their use. This promotes the longevity and reuse of products.
• Sharing economy: Platforms enable users to share resources such as vehicles, tools or accommodation, which reduces the need for new products.
• Take-back programs: Manufacturers take back used products to recycle or refurbish them, closing the material loop.

Cradle-to-cradle concept

The cradle-to-cradle concept (C2C) is a design approach in which products are designed in such a way that they are either biodegradable after use or can be fully recycled without any loss of quality. This contrasts with conventional recycling methods, which often result in a deterioration in material quality. C2C distinguishes between biological and technical cycles:

• Biological cycles: materials are designed in such a way that they can be returned to nature after use and reabsorbed by it.
• Technical cycles: Materials are designed in such a way that they can be recycled endlessly without losing quality.
