” We certify your biodegradable products according to EN 13432 and other national and international standards, where applicable. Additionally, we award two internationally recognized certification marks: our DIN-Geprüft test mark for industrial compostability and the Seedling compostability mark of the European Bioplastics association. Both can be used individually, alternatively or simultaneously, and document the degradability of your products in industrial composting facilities.”
