RECOSIC: Environment-Friendly, High-Grade SiC by Recycling
For more than 100 years, the raw material SiC has been synthesized for industrial applications by means
of the very energy-intensive Acheson process. For the synthesis of 1 t material, around 7,15 MWh of
electric energy is needed. At the same time, around 4,2 t CO2 are emitted. 2,4 t of these CO2 emissions
are caused purely by reactions, the remaining 1,8 t CO2 are emitted during the generation of the energy
needed to produce 1 t SiC. This CO2 balance publicized by ESK-SiC is very conservative as the energyrelated
emissions reflect a European power mix. In other regions of the world (e.g. China, USA, Russia),
the emissions produced during energy generation are much higher.
During the pandemic, another problem for many market partners was the interrupted supply chains,
which meant that SiC could no longer be reliably imported from countries like China or South America. It
is therefore all the more important to create an alternative with recycled material that ensures the highest
qualities in Europe. Since 2016, ESK-SiC has been working together with Fraunhofer IKTS (Fraunhofer
Institute for Ceramic Technologies and Systems) on the now patented process for the production of RECOSIC.
With Matthias Hausmann (MH), at ESK-SiC GmbH responsible for R&D/Technology, and Jörg Adler
(JA), who heads the Non-Oxide Ceramics Department at Fraunhofer IKTS, we were able to talk about this
resource-saving alternative.
