This document discusses converting supply chains into supply cycles by focusing on reverse logistics and recycling for electronics. It begins by outlining the raw materials needed to produce plastics and notes that recycling can reduce CO2 emissions. It then discusses various stages in the recycling process including de-pollution, shredding, separating ferrous and non-ferrous metals, further separating plastics from non-plastics. Options for plastic-rich streams are discussed along with growing quantities of recyclable materials. The document provides an overview of one company's process for recycling plastics including sourcing, analysis, preprocessing, separations, and production of recycled plastic pellets and compounds.
