    I am sick today (woke up worse than yesterday), so I can't make anything or see anyone, or even talk on the phone (my voice is nearly useless too) ... blah.

    Anyway ... I am distracting myself by diving down rabbit-holes, following trains of thought to ridiculous lengths.
    It's only just after 9:30 in the morning, but this one is a beauty, so I thought I might share it! :mrgreen:

    This is a list (so far short, but it will probably grow) of plastic eating organisms. Without further ado ... for no reason whatsoever, here they are:

    Bacteria:
    [FONT=&quot]Ideonella sakaiensis (PET plastic)[/FONT]

    Fungi
    [FONT=&quot]Aspergillus tubingensis ([/FONT]polyester polyurethane plastic[FONT=&quot])
    [/FONT]
    [FONT=&quot][FONT=&quot]Pestalotiopsis microspore [/FONT][/FONT][FONT=&quot][FONT=&quot](PET in anaerobic conditions)[/FONT][/FONT][FONT=&quot][FONT=&quot]
    [/FONT]
    [/FONT]

    Caterpillars
    [FONT=&quot]Galleria mellonella[/FONT] (Nickname: “Wax worm” plastic bags)
    - Note, cocoon of the caterpillar will also dissolve plastic

    Right here, silly!
    Fascinating! I wonder how long it takes for the organisms to break them down?

    IrishLass, I agree!

    To answer your question, the times appear to be:

    6 weeks for the bacteria in ideal conditions.

    2 months (roughly) for the fungi

    But the caterpillars are the quickest, taking just 40 minutes to eat a hole in a plastic bag!

    Some references:

    I vaguely remember something about them trying to use bacteria/etc on the plastic bags but then ran into an issue with the bags breaking down on the store shelves in a test....or I was in a rabbit hole LOL:bunny:
