Abstract: A method for grading the quality of cullet. Some embodiments include methods for generating a statistically significant sample of material from a collection of cullet contaminated with waste. Other embodiments include methods for evaluating various qualities of the sample with relatively simple techniques. Yet other embodiments include a uniform and reasonably simple method for communicating the results of the evaluation among different parties.
