I imagine all plastics will be out of the question. I’m wondering about what ways food packaging might become regulated to upcycling in the domestic or even commercial space. Assuming energy remains a $ scarce $ commodity I don’t imagine recycling glass will be super practical as a replacement. Do we move to more unpackaged goods and bring our own containers to fill at markets? Do we start running two way logistics chains where a more durable glass container is bought and returned to market? How do we achieve a lower energy state of normal in packaging goods?
Your quote ended before this:
It is certainly easy to sanitize clean glass that you have controlled from mold to filling with product. It is a little harder to reliably sanitize glass that the occasional customer has used for their own purposes.
When a narrow-necked bottle has been used as a smoker’s ashtray - or an addict’s sharps container - it is not “dead easy” to “sanitize” that bottle. Our cleaning process needs to be able to deal with such “contaminants”.
It’s trivial to automatically recognise and reject contaminated bottles. They differ in appearance and mass
Both glass and plastic bottles frequently get reused here in germany. Can’t say I’ve ever heard of someone having an unclean on. I don’t know where you heard that from but it’s clearly outdated or flat out bullshit.
The only time I ever remembered getting a cigarette butt was picking up the wrong beer bottle at a party.
