This course addresses the What?, Why? and How? of recycling. The What? includes a discussion of the various waste classification and recycling codes that are currently used and why they were developed. The Why? begins with a description of Economic Value Stream Mapping and Life Cycle Analysis, and how these are used to justify specific wastes to target for recovery. The How? is a detailed discussion of current and emerging industrial recycling technologies, with a focus on those used in the recycling of metals (non-ferrous, precious and REEs) and plastics. Specific processing steps that will be covered include separation and sorting, pyrometallurgy (smelting, incineration and pyrolysis) and hydrometallurgy (leaching, solvent extraction and precipitation). At the conclusion of this course students will have the basic engineering skills to determine the material values, synthesize a conceptual flow sheet and determine to an order of magnitude if it is viable. Lectures will be complemented with laboratory demonstration of processes.
