Abstract
Techniques for creating recycled plastic materials from waste plastic materials are described. A recycled plastic material contains at least a primary polymer, a secondary polymer, and residual additives. Predetermined properties of the recycled plastic material can be controlled by selecting the types of waste plastic materials used in the recycling feed, determining the types and amounts of recycled plastic material recovered from a separation process and blending the recycled plastic material with other materials.
