speaking as an automotive engine mechanic, another problematic plastic youll encounter is stuff that goes in your car or light truck. these plastics are doped with chemicals to help them withstand rodents, cold weather, or excessive heat/UV. The panels from a 1993 Saturn, while revolutionary in their dent resistance, are landfill fodder. No one will touch them. Certain parts near the ECU will also come doped with electromagnetic shielding. The PHB's at BMW apparently got pretty fired up around fibre reinforced plastics around 2010 as well...so much so that most components like radiators, pumps and switches are all glass fibre reinforced polyplastics. These cant get recycled, even though they contain metal parts that often can.
