    Metals are also not 100% recyclable due to contamination. We just have plenty of use for low grade metal alloys.

      Which literally means “anything other than aerospace engineering”. Aluminium and other metals are infinitely more recyclable than plastics, which as I’ve said before, degrade immediately to being barely usable.
