Abstract

Isolated quantities of plastic solids having greater than 70% by weight polyethylene terephthalate (PET) also include a) from 0.1% to 10% by weight polyvinyl chloride (PVC), and a moisture content of less than 4% by weight, or b) from 0.05% to 10% or 0.1% to 4% by weight halogens, or c) from 0.1% to 4% by weight polyvinyl chloride (PVC), and at least 0.1% by weight of solid materials that do not phase change below 270° C. and 1 atm. The quantities of these solid plastics are suitable for use as feedstocks to various chemical recycling processes.
