Cordenka

What Cordenka does

Cordenka GmbH & Co. KG is a privately-held German industrial manufacturer headquartered at the Industrie Center Obernburg, producing bio-based technical rayon (viscose multifilament yarn) from renewable wood-pulp cellulose. The company claims to be the world's leading manufacturer of industrially biodegradable rayon yarns and serves four primary end-markets: tire and rubber reinforcement (primary), agriculture/horticulture (via CORDENKA® Growth compostable cords), geotextiles, and fiber-reinforced composites, with high-purity sodium sulfate sold as a manufacturing byproduct.

The core technology is a proprietary wet-spinning viscose process that converts natural cellulose into high-performance multifilament yarn, certified for bio-based content (ASTM D 6866:2022) and home/garden compostability (NF T51-800:2015). Cordenka is investing in industrial AI applications, notably in-house computer vision systems that use webcam-equipped surveillance cars to detect spool fill levels and broken threads across thread clusters of more than 700 individual threads; these were developed with TH Aschaffenburg University and SPIE Automation under the AI Transfer Plus program and recognized with the BMBF "Researching Company" seal. The company also holds ISCC+, EcoVadis Gold, CDP B-Rating, SBTi-validated emissions targets, and triple ISO certification (9001/14001/50001).

The business model is B2B industrial sales: direct relationships with tire manufacturers, agricultural operations, geotextile firms, and composite producers, with quote-based pricing on technical specifications. Go-to-market is sales-led supplemented by trade show presence (notably Techtextil 2026 in Frankfurt) and content marketing. Sustainability credentials function as a key sales lever, particularly as downstream OEMs face tightening bio-based content and Scope 3 reporting requirements. The company operates one main production facility in Obernburg with a secondary operational site at Mühlhausen (via wholly-owned subsidiary CORDUS GmbH, which is now also hosting a 4 MWh battery storage project with Scale Energy).
