CIRCONOMY® Hub

Welcome to the project

CIRCONOMY® Hub

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.

Building Materials and the Climate: Constructing a New Future

Under the premise that the world wants to achieve its goals for net-zero emissions from the construction sector by mid-century, there is an urgent need for action regarding the development of new models for collaboration on the decarbonization of building materials. We must pursue the following paths together:

1) Avoiding the extraction and production of raw materials by creating a circular economy

2) Shifting to circularly managed material practices through the use of ethically produced, low carbon, earth and bio-based building materials.

3) Optimizing methods to radically decarbonize conventional materials.

“Circular innovations often emerge at the intersections”

CIRCONOMY^® was launched four years ago. The initiative’s goal: to connect stakeholders from business, academia, politics, government and civil society within innovation ecosystems and to accelerate the practical implementation of the circular economy. In this interview, Hartmut Pflaum explains the momentum CIRCONOMY^® has already generated.

Geotextiles made from recycled materials

For the industry, recycled materials are creating new opportunities in geotextile production. In the GREEN project, the Fraunhofer Cluster of Excel-lence Circular Plastics Economy CCPE demonstrates that recycled polypro-pylene (PP), polyethylene terephthalate (PET), and high-density polyeth-ylene (HDPE) can be processed into nonwovens, fibers, and membranes that meet industrial requirements. This creates opportunities for use in existing production lines and new value chains in the geotextile market.

The “CircuPEM” project is developing solutions for recycling the core components of an electrolyzer

The “Membrane Electrode Assembly (MEA)” is the central functional component of PEM electrolysis: It is where electrochemical water splitting takes place using renewable electrical energy to produce green hydrogen. At the same time, the production of the electrode and membrane assembly involves the use of critical and costly raw materials such as iridium, platinum, and titanium.

From the research lab to bicycle production

A single drop of oil can contaminate up to 1,000 liters of groundwater. The Fraunhofer Institute for Surface Engineering and Thin Films IST will demonstrate how industrial manufacturing processes can be made more resource-efficient at Lower Saxony Day 2026 on the Braunschweig Mile. The institute’s presentation will focus on the COAD® process, a plasma process developed at Fraunhofer IST for the controlled adjustment of adhesion properties on surfaces.
