This webinar deals with recycling, especially within a processing plant.  Special problems with post-consumer recycle are also addressed.  Resin-makers are involved indirectly as they control thermal stability and pricing, but the processors end up with the problems and solutions.   The most money-saving and environmental benefit is replacing new material, but some unsalable product and trim are sold off, some is still being sent to China, and some is just thrown away.  The ideal is reuse in the same product, but this “loop-closing” is environmentally irrelevant as long as new material is replaced.  Further discussion covers grinding, repelletizing, mixing and blending, additives, upgrading (stronger polymer), color change, contamination, and testing of components and finished products.
