Recyclass
I have been reading the “Recyclass Design Book” June 2022.
On page 10 it says “Flakes are melted and mixed during extrusion, to obtain plastic pellets. At this stage, certain components can degrade the quality of the output material. These include polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC) which contain chlorine that reacts with recycling temperatures, causing degradation, or bio- and oxo-degradable materials (PLA, PHA, starch) that promote breakage and lower the recyclate quality.”
Symphony Environmental Technologies plc (LON:SYM) is a world leader in the development of additives to make ordinary plastic biodegradable and protective technologies to enhance plastic products.
