Circe Biotechnologie GmbH

Circe Biotechnologie GmbH is an Austrian biotechnology company specializing in gas fermentation technology to produce single-cell protein. By moving away from traditional, sugar-based platforms to a C1 fermentation process, the company enables the conversion of waste biomass streams into sustainable protein products. Their interdisciplinary team manages a portfolio of bioreactors, including research-scale setups in Seestadt, Austria, and a 5,000L loop fermenter in Teesside, UK, used for scale-up activities and customer sample production. This approach focuses on circular bioeconomy principles and aims to provide scalable, climate-resilient solutions without relying on primary agricultural crops.

The company's technology is designed to address the environmental challenges of food production by decoupling protein manufacturing from land and traditional farming resources. Through ongoing international R&D projects and academic partnerships with institutions like the Technische Universität Wien, Circe works to refine its strains and bioprocess efficiency. By engaging in early-stage planning for industrial-scale facilities, the firm supports partners and customers in accessing sustainable, high-yield protein alternatives, thereby promoting scientific knowledge sharing and industrial sustainability in the protein sector.
