    What to do with plastic bags with oneway valve

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Im in a dilema because I hate wastage and like to recycle and so I have kept the plastic storage bags with the oneway valve from roasted coffee purchases to reuse for my home roasted beans but the bags, even though I have washed, dried and aired them still have the smell of old coffee. *The cook in me tells me not to use them for my freshly roasted coffee because of possible taste contamination but maybe its different for coffee. *Can someone please advise whether I need to use a new bag for every roasting *:( *or is it OK to recycle :)
    Thanks

    As posted before (not my idea!) you can use small freezer bags to line the one way valve bags.

    Then simply throw out the freezer bag and reuse the one way valve bag. Using this method I usually get 3-5 roasts out the bag.

    I was just about to post the same answer

    I believe TG came up with that idea

    I re use BUT only a few times and then they go in the recycle bin...

    Q: Why A: The zip lock looses it grip and depending on the bag... Holes...

    I did wash with normal disk washing and a rince and then hang out or place on a wire frame so they they were open to plenty of air...


    I have tried using a little coffee cleaner instead of the normal washing up detergent and it appears to be better at getting rid of the stale oils etc


    I still only reuse 3or 4 time at the most and some times the ziplock is in such poor shape they can not be reused.

    Same here. Maybe someone should come up with a new designed bag with a much better zip lock? I known I would buy it!

    Theyd want to charge 4 times as much so as not to lose their profit.

    Hi Addicted,
    whilst I am not helping to answer your question, I am so pleased to see you ask it as I have been wondering the same thing!

    I wondered if people did wash them, its unfortunate that you cant turn them inside out to dry ..........

    OMG its turning into a domestic guidelines thread!!! :D

    Re: What to do with plastic bags with oneway valve

    I think TGs idea is one of the best though; lining the 1-Way with a suitable freezer bag. Still not completely gas-tight though but no contamination issue to worry about.

    A pity someone hasnt come up with a reusable clip or bag sealing device other than having to heat seal in order to achieve a gas-tight end result. Ive had a look at the ones Aldi had available (in our local store) a while ago but they didnt look very robust and probably a little too small for 500g+ bags.
