NIR/SWIR Spectral Library of Plastic-Substrate Mixtures

<p>NIR/SWIR spectra of substrate-plastic mixtures at varying concentrations</p> <p>Plastics include polyethylene (PE), polyethylene terephthalate (PET), polylactic acid (PLA), polypropylene (PP), polyvinyl chloride (PVC), and styrene-butadiene rubber (SBR)</p> <p>Substrates included 3 soils (Bu5, W6, TG), crushed cement (C), oak leaf powder (V), and water (DIW)</p> <p>Concentrations of 0% (pure substrate), 0.15%, 1.5%, 5%, 15%, 50%, and 100% (pure plastic)</p> <p>Datasets are in .csv format for reflectance spectra, absorbance spectra, absorbance 1st derivative, and absorbance 2nd derivative. Reflectance spectra are also included as .hdr and .sli for ease of importing into ENVI or other hyperspectral image processing software. Additionally, raw ASD spectra and the python script for processing are included for custom spectral processing or analyses.</p>
