Ecodesign, a preventive approach to environmental problems at the start when products are designed, has had a positive impact on profit margins for specific products and even on corporate profits. Whereas ecodesign focuses on the beginning of a product’s life cycle, the circular economy tends to pay more attention to the end. What actually happens to a used-up product? What is its place in various industrial or natural cycles? In a circular economy, ecodesign must reckon with new objectives, such as recuperating materials, reusing them in the production process, increasing product life spans, renting products and improving the quality of services. Taking these new objectives into account is made easier through an integrated approach to product/service systems that allows for developing other value-added models and an “economy of functionality”.
