Recyclates after Supercritical CO2 - XRF

The purpose of this analysis is the development of an efficient sampling protocol for plastic waste streams after the treatment with scCO2.

Taking into consideration the morphology of the recyclates after scCO2, the samples were prepared based on the model waste (MW) approaches. The recyclates after scCO2 treatment are in the form of flakes, however due to the high heterogeneity of the material and possible low accuracy of analytical evaluation, an extra step of grinding was added to increase their representativeness.

The sampling approaches from the (MW) were applied to the recyclates, and each was assessed via various analytical techniques.

This dataset contains raw XRF data of the recyclate from the different sampling approaches, such as:

•Excel files containing XRF data of the recyclate, wherein the approach was based on cryogenic grinding and cryogenic grinding combined with scCO2, with a measurement protocol

·One Readme file containing further information about the methodology and nomenclature 

This dataset was generated in the framework of PRecycling Horizon Europe project (101058670)
