As a future concept, DoCircular2030 will identify solutions and models for the city administration, Dortmund companies, science and consumers that reduce the absolute use of resources ("Reduce"), extend product life cycles ("Reuse" and "Repair") and contribute to the reuse of materials at the end of a cycle ("Recycle"). At the same time, these should contribute to socially sustainable and public welfare-oriented development. A circular economy aims to close material cycles as completely as possible and reduce resource consumption, thereby contributing to climate neutrality and the preservation of natural life-support systems. Among other things, it offers companies the opportunity to open up new markets with innovative business models and to break free from supply dependencies. A growing number of Dortmund companies and start-ups are already developing and marketing circular innovations. https://www.wirtschaftsfoerderung-dortmund.de/dozirkulaer2030
