Welcome to the project



Sustainable production, sustainable consumption and a circular economy require systemic and technological solutions, which are created in innovation networks. Fraunhofer proposes building a network of CIRCONOMY® Hubs across Germany: These hubs are a new, agile instrument for cooperation on the basis of a shared mission and a reliable data space. They create added value regionally, nationally and internationally. In each hub, Fraunhofer institutes work with their partners in industry, science, politics and society on a mission not just to contribute to the circular economy, but to develop innovations for sovereign value cycles, climate neutrality, circularity and bioeconomy.

On this page you can read about how circularity is created out of shared values, cooperation and projects.

CIRCONOMY® is the Fraunhofer brand for solutions, capacities and expertise for the circular economy. This brand represents shared values, strategies, target visions and, above all, innovation projects that put the great mission of “transformation to the circular economy” into practice.

Our offer



Web services can be tested directly on a website. Techno-consulting helps keep innovation projects on track and successful.



The concepts for the first CIRCONOMY® Hubs are already being created, and circular ecosystems are forming. Be there as CIRCONOMY® Hubs shape the transformation.



Personal preferences, social relationships and available options determine our mobility behavior

The mobility transition requires an intelligent networking of all mobility options. Besides achieving better individual mobility with less traffic, it is critical to reduce the environmental impact of vehicles and mobility systems. Digitization and AI can play a decisive role in development, testing, validation and system networking. In KAMO (short for »Karlsruhe Mobility«), we address current and future challenges faced by individuals, companies, local authorities and the environment through knowledge transfer, practical examples and smart technologies.


World Record Efficiency of 15.8 % Achieved for 1 cm² Organic Solar Cell

Organic photovoltaics (OPV) opens up new areas of application for solar energy thanks to its climate friendly and inexpensive production and its flexible and potentially transparent solar cells. To help this technology achieve a market breakthrough, research institutes worldwide are working to improve the efficiency and scalability of organic solar cells. Researchers at the Fraunhofer Institute for Solar Energy Systems ISE and the Materials Research Center FMF at the University of Freiburg have now improved their own efficiency record, announced back in September 2020, for an organic solar cell with an area of one square centimeter.


New guide to the future of plastics

How does a future-proof, circular and sustainable plastics economy look like? The answer is a balance ranging from plastics reduction to a sustainable use of recyclable plastics. After all, the increasing demand for plastics in high-value applications such as food packaging, car parts or synthetic textiles requires a holistic change. With four strategic approaches, researchers from the German institute Fraunhofer UMSICHT and the Dutch institute TNO now provide insights into how this future scenario could look like in their recently published white paper "From #plasticfree to future-proof plastics". 


Reducing climate-damaging emissions with lightweight drive shafts

Lightweight design is essential for sustainable mobility. Drive shafts made of carbon-fiber-reinforced plastics (CFRP) with a thermosetting matrix, for example, can reduce climate-damaging emissions. Nevertheless, the lightweight design and resource-saving potential of these shafts has not been completely realized yet. Together with partners, researchers at the Fraunhofer Institute for Applied Polymer Research IAP are developing a new, very lightweight drive and side shaft system for cars and trucks whose matrix consists of thermoplastic materials. These materials can be recycled and have an additional weight advantage.
