Instead of recycling recepticals for plastic bottles, a sort of bottle washing device should be placed in a public area with an attached water fountain to refill the clean bottles. There are numerous ways this can be designed, but basically an enclosed area that sterilizes the bottles with hot water
would be most obvious.

Hot water melts the cheap plastic and deforms it. |
|
| |
Boiling water forces the stretched blow molded plastic to return a bit toward the preform. It may also change the optical character making it cloudy. A peanut butter jar I boiled shrank so much the threads no longer held the lid on. |

Maybe use radiation to kill / clean the bacteria, etc. |

I have a vague notion that this is baked... perhaps it was just a water-bottle washing spigot in a park or watching somebody power-rinse a water-cooler bottle. |

What exactly are people doing with their plastic
bottles that requires them to be heat-sterilized or
irradiated before reuse? |
|
| |
The idea is this would replace plastic bottle recycling recepticals in
public areas, and the obvious reason you already know is the
tendency for people to become brew vats for infections. |

But- they say the plastic contains and/or acquires contaminants and bacteria, so it is not wise to use them more than 2 or 3 times - even if washed. |
