Seedling – Certification for Compostability
Seedling is an independent third-party certification that verifies the compostability of a product in an industrial composting plant in accordance with the European standard EN 13432. The Seedling certificate does not cover home composting.
The certification process is conducted by independent certifiers DIN CERTCO (Germany) and Vinçotte (Belgium). In order to be certified compostable, the product must undergo a stringent test regime carried out by recognised independent accredited laboratories. The certification process includes the following procedures: 1) chemical characterisation of the product 2) testing of ultimate biodegradability 3) disintegration under practice-relevant composting conditions and 4) definition of the quality of the compost (ecotoxicity test on two plant species) 5) infrared spectrum recording to enable the identification of the material. Both the evaluation criteria as well as test circumstances and methods comply with the EN 13432. To ensure continuous compliance with the certification requirements regular inspections take place.
Products that have successfully passed the strictly defined and documented tests and been formally certified by one of the certification bodies may feature the Seedling logo, a registered trademark owned by European Bioplastics. According to European Bioplastics a product marked with the Seedling logo can be disposed of in the biowaste collection. However, regional specifications for the separate collection of biowaste may exist and detailed information can be obtained from the local municipalities or waste management authorities.
Since the establishment of the Seedling certificate approximately 780 products, 110 intermediates and 330 materials have been certified, including the Bamboo Fibre Straws.
