Industrially compostable plastic materials or products certified according to EN 13432 / 14995 are allowed to carry the Seedling compostability label. This brand is owned by European Bioplastics. The independent certifiers DIN CERTCO (Germany) and TUV Austria (Belgium) carry out this certification process. An alternative is the ‘OK compost’ label issued by TUV Austria. It is based on the same standards.
The certifiers DIN CERTCO (Germany) and TUV Austria (Belgium) have also introduced labels showing the biobased carbon content of bioplastics. The measuring of the biobased carbon content is based on CEN/TS 16137.1
