Black plastics identification for sorting and recycling with deep-UV Raman spectroscopy

Raman spectroscopy in the deep-UV (DUV) wavelength range is suitable for black plastics because the fluorescence emission that occurs over the near-UV and visible range will not overlap with the Raman spectrum. Here we show raw Raman spectra of polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET) to support the study titled "Black plastics identification for sorting and recycling with deep-UV Raman spectroscopy". Spectra are given in ASCII or text format, with the first column showing the Raman shift (in cm-1) and the second column the intensity in arb. units. Laser wavelength was 248.6 nm. Folders F2 - F5 contain the raw spectra of the corresponding figures in the main manuscript. Additional spectra were recorded for black plastics and other objects collected from a household waste stream at the NTCP recycling facility (Folder S1), black objects acquired from a local supermarket in the Netherlands (Folder S2), and additional objects with/without sleeves and multilayered packaging (Folder S3). Each folder is divided to three folders to indicate the experiment(s) these items were used (Lab, Stationary on a conveyor belt at NTCP facility or Moving on a conveyor belt at the NTCP facility).
