    Ink Disposal

    This may seem like a silly question to some of you guys but I am new to solvent printing and I am not sure how to dispose of the waste ink. I am running a Mutoh 1614 with Eco Solvent inks.

    Are there companies out there that pick this stuff up?

    That's Illegal, at least here it is. Call your garbage company, they should be able to tell you who is licensed for removal in the area.


    EDIT, now I see you said Eco-Sol. Mutoh's MSDS says it's not hazardous waste. Jhill is right.

    I'm not sure if it's illegal to do it that or not, but instead of taking a chance.... we just put it into cans and then into drums and once a year at a local business, they have commercial toxic waste day. You can drop off anything you want and they take it away for free.

    That's what I would do as well. Better safe then sorry.

    We have a paint booth in house so we just dump our waste ink into the paint waste barrel. There is a waste company that picks it up when it gets full and delivers an empty barrel.

    I just cant figure out why we are allowed to throw away anything that is printed then? How is a vinyl with dry ink on it any different than kitty litter with dry ink in it?
    I have not tried the kitty litter method and have stored mine in 5 gallon drums until I find a way to get rid of it. So far I have not found a company here that picks it up, mind you I have not spent to much time looking either.
    The municipality will take old paint cans and such but only from residential.

    So hypethetically if I had a waste container full of old paper could one not just spread the ink around and let the paper absorb it? then in 24 hrs it is dry and acceptable for pickup?

    Because the solvent does not evaporate out of the kitty litter like it does out of our banner material.

    If you can remove the solvent then yes, I suppose that would be the same technically. The problem is that you are a business that is dealing with a labeled hazardous product. Do you really want that exposure?

    Think of it more like motor oil or antifreeze. Would you dump that into the kitty litter then in the toilet or dumpster?

    Some places will fine you, some will not. For me its just about not poisoning the water where you live.

    Depends on the printer and the age of the machine.

    One liter per month is not uncommon.

    I used to fill a 25 gal small drum in a year or so when I used ecosol and solvent.

    Check out heading "hazardous waste" down the bottom. Your area has a once a year free collection like Gino has mentioned for his area.

    this is of course coming from a guy who changes out his waste tank twice a year (not a high volume production shop)

    Yeah, sure. Dig to the bottom of that kitty litter bucket and see if there is any ink sludge. Most people will dump way more ink into the litter than it can possibly disperse.

    I'm not trying to pick a fight, but for those higher volume guys...and gals, this is not a "best practice"

    Bad publicity perhaps, but eco-sol is not listed as a hazardous waste. Just keep a copy of the specs to show.

    How are you pressurizing the ink to expand the balloon without making a mess? I would think the ink would "take" better to interior parts rather that the paint. Of course a ragtop would work nicely, but an open convertible would probably be best.
