For the certification, different properties were tested, such as metabolism and disintegration under industrial composting conditions. In addition, the tests showed that there was no ecotoxicity, BÜFA Thermoplastic announced on its website.

"Cellulose regenerated fibres, also known as rayon fibres, are an environmentally friendly alternative to synthetic reinforcing fibres made of conventional plastics or glass. Many everyday articles, which would actually be biodegradable, contain a small amount of non-biodegradable fibres. These can be replaced by rayon," said Dr. Kurt Uihlein, CEO of Cordenka. "This is why the compostability of our rayon fibre, which is now also certified, is an important property."

The fibre, which is based on natural cellulose, is used as a reinforcing material.

“Cellulose regenerated fibre is also interesting for use as a raw material for components made of thermoplastics, because the particularly high-quality fibres increase the impact strength,” said Dirk Punke, managing director of BÜFA Thermoplastic Composites.

Cordenka, headquartered in Obernburg, Germany, produces over 50 per cent of the global demand for industrial rayon, which is also processed into cords and fabrics. The spinning mill has an annual capacity of 32,000 tons.
