For HN readers, this is an example of "don't make perfect the enemy of good."
If even 10% of the bottles were nasty, there are machines that can handle that.
Just like Europe's progress in standardizing chargers, we need to go back to standard bottle sizes.
One of the best examples is the Beer Store in Ontario, Canada. All brewers have to use stubby brown bottles, and achieved 99% reuse in modern times:
"Between 2013-2014, the Beer Store achieved a system-wide recovery and re-use rate of 99 per cent for the industry standard bottles, which are reused 12 to 15 times."
They accomplished such phenomenal reuse that the bottles wore out. So much for excuses, eh?

- Polylactic_acid 7y agoIn this case you really do have to get the system absolutely perfect, not just good. It is unacceptable for someone to receive a bottle that contains any amount of dirt or other contaminant. I'm not an expert in this so idk how difficult it is to ensure this but unless the system is perfect it can't be used.

- TeMPOraL 7y agoYou don't have to make the system perfect. You have to make it cautious. At any time it suspects a bottle may be too dirty or not getting cleaned for some reason, it should reroute it to manual inspection line and/or straight to remelting. So now you lose 30% of your yield, but the rest is clean and sterile. That's a good starting state, from which then you can optimize the contaminant detection.
