ABSTRACT:
A system and method of identifying a reference standard library for thermoplastic content includes preparing a plurality of samples of each one of a plurality of known ratios of virgin thermoplastic/recycled thermoplastic, analyzing each of the plurality of samples of each one of the plurality of known ratios of virgin thermoplastic/recycled thermoplastic with at least one of a group of analyses consisting of: a differential scanning calorimetry analysis; a physical thickness analysis; an ultraviolet-visible spectroscopy analysis; an attenuated total reflectance Fourier transform infrared spectroscopy analysis; a mechanical analysis; or a plasma atomic emission spectroscopic analysis. The method is also comprised of selecting a contaminant, identifying a first plurality of indicators output from the at least one of the group of analyses, identifying a second plurality of indicators from the first plurality of indicators, the second plurality of indicators being independent of the selected contaminant and optimizing the second plurality of indicators to identify a third plurality of indicators, the third plurality of indicators being quantitatively different of the selected contaminant wherein each one of the third plurality of indicators has at least one corresponding value for each one of the plurality of known ratios of virgin thermoplastic/recycled thermoplastic. Systems and methods for determining content of recycled thermoplastic in a thermoplastic sample are also disclosed.
