Abstract:

A recycling method that can be used by an OEM products company or other entity to obtain recovered raw materials for use in its manufacturing operations in a manner that helps ensure the quality and traceability of the recovered raw materials. The process involves first collecting the material from one or more sources, then determining suitability of the material for processing using a series of qualifying tests separated into a two-phase review, wherein each of the qualifying tests is carried out using a composition profile for the material. The first phase of the review utilizes a source composition profile that describes salient features of the material so that it can be reviewed for suitability for processing and end uses as well as for regulatory compliance. The second phase involves similar reviews based on an analytical composition profile that is determined by physical analysis of the material.
