Thermoplastic waste

Table 16.1. Composition of post-consumer thermoplastics waste in different regions or countries (in wt%)...

Landfilling carpet waste, as well as many other thermoplastic wastes, is not sustainable. A key issue is whether post-consumer carpet (PCC) should be separated into its primary thermoplastic base polymers or used as a mixture. A composite with a matrix based on a mixture of incompatible polymers is a way of upgrading the polymer mix and is potentially inexpensive. If the reinforcing fibers dominate the composite properties, then having a matrix comprised of incompatible polymers can be tolerated. The results presented here indicate composites with attractive properties can be made using a matrix of mixed incompatible polymers.
