Abstract
A method of recycling mixed post-consumer plastics waste includes the steps of providing mixed post-consumer plastics waste including polyolef in and non-polyolefin components, and melt-compounding the waste so as to form a continuous phase including a blend of the polyolefin components with the non-polyolefin components microdispersed therein. Preferably, the waste also includes one or more intrinsic compatibilizers, and the method includes the intrinsic compatibilizers at least partially compatibilizing the microdispersed components in the continuous phase.
