The re for their compostablecertification are similar with EN 13432 (except for their heavymetals re, which are more stringent when compared to EN13432 à I already checked this and the heavy metalsre for Greenpla compostable are also fulfilled for theproduct).  Additionally, the sample needs to fulfill there of the Greenpla logo itself. This evaluation is basedon data which are probably present in the MSDS of the differentconstituents. I expect that if not enough data are available in theMSDS that they require that additional tests (probablybiodegradation and ecotoxicity) are performed. Therefore, I thinkthat it is useful to start with sending the detailed composition ofthe product together with the MSDS of the different constituents toJBPA in order to check if enough information is present in the MSDSor if they require that additional testing isperformed.
