Kehäkehitys

Kehäkehitys, a Finnish term, translates to "circular development" or "closed-loop development" in English. It refers to a systemic approach to production and consumption that aims to keep products, components, and materials in use for as long as possible, minimizing waste and maximizing resource efficiency. This concept is a core element of the circular economy.

The principle of kehäkehitys moves away from the traditional linear "take-make-dispose" model. Instead, it emphasizes designing products for durability, repairability, reuse, remanufacturing, and ultimately, recycling. The goal is to create closed loops where materials are continuously circulated, reducing the need for virgin resources and the generation of waste.

Key strategies within kehäkehitys include product-as-a-service models, where consumers pay for the use of a product rather than ownership, incentivizing manufacturers to produce durable and easily maintainable goods. Repair and refurbishment initiatives are also central, extending the lifespan of existing products. When products reach the end of their functional life, their components are salvaged for remanufacturing or their materials are recycled to be used in new production cycles.

The implementation of kehäkehitys requires collaboration across value chains, from designers and manufacturers to consumers and waste management operators. It promotes innovation in materials science, business models, and logistics to facilitate the seamless flow of resources. Ultimately, kehäkehitys seeks to achieve economic, social, and environmental benefits by decoupling economic growth from resource depletion and environmental degradation.
