T1 - Innovation Network PerFluSan N2 - Per und polyfluorierte Alkylsubstanzen (PFAS) werden im Rahmen ihres breiten industriellen Einsatzes in die Umwelt ein­gebracht, wo sie aufgrund ihrer kritischen Eigen­schaften ein Problem darstellen. Der nach­haltige Schutz von Mensch und Umwelt vor dieser Stoff­gruppe ist eine wichtige Zukunfts­­aufgabe. Verfügbare PFAS-Reinigungs- und -Sanierungs­verfahren sind jedoch teuer und oftmals unzul­änglich. PerFluSan möchte einen entscheidenden Beitrag zur Lösung dieses Problems leisten, indem hier neue PFAS-Sanierungs­verfahren für Böden und Wässer, sowie innovative analytische Methoden zum PFAS-Nachweis entwickelt werden. Die lang­fristige Vision ist es, PerFluSan zu einer nationalen Anlauf­stelle der PFAS-Thematik auszubauen, die mit Hilfe der Synergien zwischen den PerFluSan-Akteuren alle Aspekte der Problematik ganz­heitlich, nachhaltig und effektiv adressiert. N2 - Per- and polyfluorinated alkyl substances (PFAS) are transferred into the environment as part of their broad industrial use, where they pose a problem due to their critical properties. The sustainable protection of people and the environment from this group of substances is an important task for the future. However, available PFAS removal and remediation processes are expensive and often inadequate. PerFluSan would like to make a relevant contribution to solve this problem by developing new PFAS remediation methods for soils and water, as well as innovative analytical methods for PFAS detection. The long-term vision is to develop PerFluSan into a national contact point for the PFAS topic, which uses synergies between the PerFluSan actors to address all aspects of the problem holistically, sustainably and effectively.

Besides generating new feedstocks from biomass or waste polymers, the valorization of carbon fiber reinforced polymer (CFRP) waste streams seems to be extremely promising based on the high carbon content of carbon fibers (CF), chars from CFRP and even unprocessed CFRP waste of >92%, 98% and 79%, respectively. Although, reduction of environmental impact from those high-performance materials was achieved by the development of smart recycling solutions, the continuous truncation by mechanical treatment of CF over multiple cycles, analogous to paper fibers, and the large global CFRP waste stream of 62 kt/a demand for a sustainable management of end-of-life (EOL) CFRP. Recently it was demonstrated that CF can be used safely as reductant in pyrometallurgical processes in a downhole electric furnace without significant WHO fiber emission. Therefore we anticipate a huge potential of CF based materials as sustainable reductant for steelmaking in an electric arc furnace (EAF). To facilitate the applicability of EOL CFRP in steelmaking, we investigated the interaction between CF based materials and liquid metal phases, appearing during the process, on different scales. Particularly, we examined the reactivity, wettability and dissolution behavior of CF and CFRP concerning liquid slag and steel. The presented results indicate that understanding the impact of the microstructure of CF on their behavior is crucial for their application in EAF steelmaking without risking potential hazards by WHO fiber emission. Besides the detailed elucidation of structure reactivity relationships of CF, the broader impact on circular economy will be presented.

How could behavior of junctions be included? To which extend is it necessary? On the conference Geo-Chicago 2016, Swan and Yuan presented an ultimate limit state equation for the short-term material resistance of junctions. We discuss limitations and suggest improvements to include long-term behavior of junctions. Nevertheless, the approach applies only to a specific mode of shear-tensile failure of junctions and only to strictly rigid geogrids. A new design concept presented in the same year by Jacobs on the conference GeoAmerica for the special case of the anchorage of geogrids, which reinforce capping system on long and steep slopes of landfills, tried to overcome these drawbacks. We discuss the aspects of this concept related to the long-term behavior of junctions and the interplay between the load applied to junctions and the flexibility of longitudinal ribs. This interplay and the long-term junction strength determine the long-term behavior of geogrids.
