Based on, but not limited to, advanced materials and production technologies, the demand for natural resources and CO2 emmissions are reduced by lightweighting during production, as well as use phase. Therefore, lightweighting is a crucial transformation technology assisting in decoupling economic growth from resource consumption. In this manner, lightweighting contributes significantly as a key technology of relevance for many industrial sectors such as energy, mobility, and infrastructure, towards resource efficiency, climate action and economic strength, as well as a resilient Europe. To strengthen international partnerships, addressing global issues of today at the edge of science with high performance lightweight material based on carbon fibers, an overview about the BAM expertise in carbon fiber reinforced materials is given.

A1 - Adam, Christian T1 - End-of-Life Carbon Fiber Reinforced Polymers in Steelmaking - Accessing a C-Rich Residue Stream as Alternative Reducing Agent N2 - As one of the most energy and carbon consuming industries, steelmakers have an intrinsic interest in the development of technologies, reducing their carbon footprint as well as their carbon input. 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.

Because of their low reactivity towards oxidation processes, CF can neither be treated in a conventional nor hazardous waste incineration plant. Even the extremely high temperature in a cement rotary kiln does not lead to full conversion. To increase the sustainability of CF, other processes need to be investigated. Opening other reaction pathways, using CF waste streams as secondary resource in pyrometallurgy to replace fossil carbon, can be a solution for a safe and sustainable treatment. After first small scale experiments, CF containing waste streams were used as reductant in a semi-industrial scale electric arc furnace (EAF). First results and impressions are presented.

Sitzung des projektbegleitenden Ausschusses N2 - Obwohl der Leichtbau mit carbonfaserverstärkten Kunststoffen (CFK) einen wichtigen Beitrag zum Klimaschutz und zur Ressourceneffizienz liefert, stellt der wachsende Abfallstrom von aktuell 62 kt/a eine große Herausforderung dar. Weil die Produktion von Carbonfasern (CF) überwiegend auf fossilen Rohstoffen basiert und sehr energieintensiv ist, werden nachhaltige Recyclinglösungen dringend benötigt. Hier geben wir einen Überblick über aktuelle Recyclingprozesse und diskutieren deren Limitierungen. Darüber hinaus zeigen wir eine Möglichkeit zur sicheren chemischen Nutzung von CF-haltigen Reststoffen auf, die nicht zur Wiederverwertung geeignet sind. Das Projekt CF Pyro untersucht deren Einsatz als Sekundärrohstoff in der Pyrometallurgie und setzt besondere Schwerpunkte bei der Reaktivität von CF, der Prozessstabilität und der Vermeidung von Emissionen gesundheitsschädlicher WHO-Fasern. Neben der Vorstellung von wichtigen fundamentalen experimentellen Erkenntnissen wird ihre Bedeutung für den Wandel zum zirkulären Wirtschaften diskutiert. T2 - 4.
