    Hi all,

    I'm installing a grey water diversion system under my house and I'm wondering whether anyone would consider it unwise to use a 44 gallon drum that previously contained a low styrene emission ortho-unsaturated polyester resin called Estarez 1440 45 LSE. I assume that once the resin has cured it should be non-toxic. The grey water will be used on vegie gardens, hence my concern.

    Any advice greatly appreciated. Thanks in advance.

    George

    A 44-gallon drum (metal?) is quite small. Why don't you purchase a larger water tank that is designed for the purpose?

    I think it might be wise not to risk it.maybe for waste water systems it would be ok,but food usage i wouldn't take any chances

    Estarez is a trade name so we cannot determine the actual composition of the compound. I cannot say yes or no to your concerns. But if it were my veggie garden, then sure, I'd use it. Start by using the metal drum as a burn barrel. After a few hours of burning paper and sticks, it should be good to go.

    I looked it up and it is a low styrene emission ortho-unsaturated polyester resin. Unfortunately I can't do the fire trick because the drum has a sealed lid.

    As these kinds of resins set hard when in contact with air, I assume it would be become inert. Half a dozen flush diversions and then it should be fine?

    What makes you think the plant is even capable of absorbing whatever toxic chemical is left? I don't believe styrene is even considered toxic to humans (if that is your concern)...

    Agreed, George Michael. A resin that cures hard and is flushed multiple times, ought to be safe for your purpose. Another layer of protection is that we are not drinking the output water directly. It is simply used for irrigation. The only problem is that we cannot speak with certainty. The best we can do is take educated guesses. So my statements are just that -- guesses.
