ecovio® PS1606 fragments per gram of compost after worst-case scenario A spiking by micronized ecovio® PS1606, then particle extraction (using ZnCl₂) and analytics [18]. Results compared to LDPE and compost blank. a) total number of ecovio® fragments by µ-Raman microscopy; b) total number of polymer fragments by fluorescence microscopy; c) particle size distribution (area-equivalent diameter) for each timepoint by fluorescence microscopy
