PET(E) and HDPE are both extremely recyclable (not in the infinitely recyclable approach but in the “have lots of long second lives” approach), though something like only 30% of HDPE ends up getting collected for recycling in the first place. This Argonne National Laboratory article is more pessimistic but maybe because it’s trying to hype up a recent breakthrough which actually makes HDPE infinitely recyclable: https://www.anl.gov/article/scientists-enhance-recyclability-of-waste-plastic https://www.anl.gov/article/scientists-enhance-recyclability...
