Abstract: The present invention relates to relates to a method of optimizing a plastic composition formed from a plurality of resin feedstocks. A plurality of resin feedstocks are provided. The plurality of resin feedstocks are blended to form the plastic composition. One or more properties of the plastic composition, including radiation absorption, radiation transmission, gas evolution, radiation fluorescence, or melting properties, are measured. The ratio of the plurality of resin feedstocks being blended into the plastic composition is adjusted, based on said measuring, to form an optimized plastic composition. A system for performing the method is also disclosed.

Abstract: A system and a method for determining a percentage of recycled polyethylene terephthalate present in a test sample includes selecting a contaminant from a set of known contaminants. At least one predictor analyzes is identified from a group of predictor analyzes as being a statistically independent predictor analyzes of a presence of the selected contaminant. Predicting a percent recycled polyethylene terephthalate, identifying at least one set of best subsets of the statistically independent predictor analyzes of percent recycled polyethylene terephthalate and refining a percent recycled polyethylene terephthalate statistical model to a final predicted percent recycled polyethylene terephthalate model.

Abstract: A method including steps of providing at least one sensor; detecting a plurality of parameters in a thermoplastic using the at least one sensor; generating a plurality of outputs in response to the detecting; and characterizing a contaminant or a percentage of post-consumer recycled thermoplastic content in the thermoplastic as a function of the plurality of outputs having been generated and a thermoplastic pattern signature.
