The re for their compostable certification are similar with EN 13432 (except for their heavy metals re, which are more stringent when compared to EN 13432 à I already checked this and the heavy metals re for Greenpla compostable are also fulfilled for the product).  Additionally, the sample needs to fulfill the re of the Greenpla logo itself. This evaluation is based on data which are probably present in the MSDS of the different constituents. I expect that if not enough data are available in the MSDS that they require that additional tests (probably biodegradation and ecotoxicity) are performed. Therefore, I think that it is useful to start with sending the detailed composition of the product together with the MSDS of the different constituents to JBPA in order to check if enough information is present in the MSDS or if they require that additional testing is performed.
