Fraunhofer Research Institution for Materials Recycling and Resource Strategies IWKS

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

Fraunhofer IWKS stands for the responsible use of resources. Recovering valuable materials from a product cycle and reintroducing them into a new cycle - that is the goal of research. The energy transition, the mobility transition and digitization in particular are accompanied by an increased demand for specific raw materials, without which the respective technological functionalities cannot be realized.

Together with industrial partners, researchers are developing efficient processes and technologies for the responsible use of the earth's resources.

Accessibility in times of Corona

The Corona pandemic poses major challenges for all of us. In order to slow down the spread of the virus and protect everyone's health, most of the Fraunhofer IWKS team is now working from a home office. There, we are available for you by phone or e-mail and try to reduce the restrictions on project work to a minimum.

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

Stay healthy.

Standardization for the recycling of PV modules

Solar energy plays a major role in the renewable energy mix for Germany, but also worldwide. Already today, different, more or less efficient processes and concepts for the recycling of discarded PV modules are in use. However, in order to evaluate them, there is a lack of standardization and norming of recycling processes for PV modules, so that the full potential of recycling can be exploited. This goal has now been addressed by the project "Standardization and Norming of Recycling Processes for Silicon Solar Modules - ReSi-Norm".

International Conference on Resource Chemistry

The aim of the event was 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 environment, this conference focued on applied resource chemistry and new recycling technologies. The conference covered 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 conference tackled these challenges and brought together scientists and experts from various fields such as resource & green chemistry, biology, environmental science & technology, as well as material sciences.

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.
