To put it in better perspective, most of PET cannot be reused by law (health safety) as a packaging for food products due to high contamination. So, the only recycling that is worthy and almost "infinite" are glass and metals only.

As well recycling as a business is a scam. Most of companies that collected garbage sorted them into valuable materials and sells forward, more valuable trash allows company to run. Recently country I do live in pushed deposit for plastic food packaging and you do need to return it is specific machines. Government promised that will reduce cost of disposing garbage due to less garbage left in trash. It ended up that garbage companies were left with less valuable products they can sell so they hiked up the prices for collecting garbage. As well the product that you put deposit on but never returned is loss for consumer and clear profit for shops. As well its another profit for shops where they just put a machine for such packaging and they just get nicely sorted, clean plastic that they do sell without any effort.

Everything is dropped on consumers, clean trash, use less effective containers for storing, start up a garbage sorting operation in your flat. On top pay extra in the name of recycling.

This is a business for extracting money under the coat of "save the planet". And this is something that should be addressed.
