    When I've occasionally online ordered perishable items they usually come with frozen gel packs, usually inside a polystyrene or other insulated lined cardboard box.
    Does anyone have any bright ideas of how to recycle these things or the liquid/gel within them. Invariably the sender doesn't want them back, its just too difficult to organise?

    We had some in a pack of frozen stuff the other day we thought we would reuse and take when shopping in a cool bag (whenever we get back to doing that.) Problem was having thawed them out they leaked so got ditched.
    Mind you though the polystyrene boxes comes in handy I use them to chit beans and peas in compost prior to sowing in modules or outside.

    My guess is the contents are mostly water as it has a high specific heat capacity. I suspect its in gel form to minimise the impact of a leak?

    Google finds its an issue but not much advice..


    "Can the Gel packs be recycled?
    Why not re-use them? These gel packs are great for picnics or lunchboxes, but if you want to dispose of them, simply cut the corner of the pack and dispose of the contents through the normal domestic waste system. The contents are benign, given the dilution of the polymer and purification of the water they are not at all harmful to the environment. The outer film is totally recyclable as LDPE 4."


    "To dispose of an ice pack, start by checking whether the ice pack is just frozen water or something else. If the ice pack contains anything other than water, thaw it, cut it open and then squeeze the gel into the garbage. Afterward, rinse out the plastic film, dry it and bring it to a plastic bag drop-off. Gel from ice packs will cause bad clogs in your drains, so make sure this gel doesn’t get washed down a sink or flushed down a toilet."
