Keeping resources in circulation

This is the aim of the research work of Fraunhofer IWKS. Avoiding waste by recovering and recycling valuable raw materials or replacing them with sustainable alternatives. The implementation of developments in industry is an important goal of the research work.

Welcome to Fraunhofer Research Institution for Materials Recycling and Resource Strategies IWKS

We stand for the responsible use of resources. Recovering recyclable materials from a product cycle and reintroducing them into a new cycle. This is the goal of our research. In particular, the targeted energy revolution, the mobility revolution and digitization are accompanied by an increased demand for specific raw materials, without which the respective technological functionalities cannot be realized. Together with industrial partners, we are developing efficient processes and technologies for the responsible use of the earth's resources.

Accessibility in times of Corona

The corona pandemic presents us all with major challenges. In order to slow down the spread of the virus and to protect the health of everyone, the majority of the IWKS team now works in the home office. We can be reached there by phone or e-mail and try to keep restrictions on project work to a minimum.

We thank you for your understanding and look forward to a further successful cooperation.

Stay healthy.

International Conference on Resource Chemistry

The aim of the event is to discuss current developments in resource chemistry. In times of increasing pressure on industry and politics with respect to environmental protection and climate change, material sciences and chemistry have to join forces to provide answers to some of the world‘s most challenging technological tasks. Under the aspect to secure and provide indispensable materials in a limited environ-ment, this conference will specifically focus on applied resource chemistry and new recycling technologies. The conference aims to cover a wide range of research areas, from the substitution of critical elements, to the development of sustainable materials, and the establishment of efficient material life cycles. This unique conference will tackle these challenges and bring together scientists and experts from various fields such as resource & green chemistry, biology, environmental science & technology, as well as material sciences. Accomodation: We have reserved a hotel contingent for you in various hotels in Darmstadt (more hotels to follow) - all hotels are within easy reach of the conference venue. Please note: The hotel contingent at the fixed rate is limited - we recommend booking your room as early as possible.

PIUS Länderkonferenz

Climate change is becoming increasingly evident and with it the urgency to act. By using resources more efficiently, companies can not only save materials, energy and costs, but also significantly reduce their CO2 emissions, thus making an important contribution to climate protection. In addition to examples from corporate practice, the event will present the latest research findings on resource efficiency. The conference will be opened by Tarek Al-Wazir, Hesse's Minister of Economics. Keynote speakers are Mathis Wackernagel, President and founder of Global Footprint Network, and Dr. Janez Potocnik, Co-Chair UNEP International Resource Panel.
