PP-recyclates characterization after different sampling and recycling strategies – XRF data

The purpose of this analysis is the development of an efficient sampling protocol for plastic waste streams after upcycling or the treatment with scCO2 and solvent-based recycling.

Taking into consideration the morphology of the recyclates after upcycling, the samples were prepared based on the model waste (MW) approaches. The recyclates after upcycling are in the form of pellets, therefore the MW approaches were selected in which extrusion processes were used.

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.

Taking into consideration the morphology of the recyclates after solvent-based recycling, the samples were prepared based on the model waste (MW) approaches. The recyclates after solvent-based recycling treatment are in the form of powder, therefore the MW approaches were selected in which cryogenic grinding processes were used.

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 recyclates, wherein the approach was based on upcycling (compounding), supercritical CO2 treatment and solvent-based recycling treatment 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)
