Not really. Plastic gets damaged when heating it up to melting temps. You won’t get a product that has the same properties, unlike with aluminium for instance. You can maybe get away with adding a small percentage of recycled pellets back in, but that’s it.
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.
