Safe disposal of contaminated substrate?
    #11359590 - 10/31/09 09:28 PM (7 years, 11 months ago)

I've got a small coir tub that almost immediately grew over with green - the substrate was never really colonized by the mushroom mycelium because the mold grew so fast.

What's the safest way to dispose of my moldy dirt? I live in the city and don't want to just dump it outside.

I did a bit of searching and the only idea I found that seemed useful came from an old post by Roadkill where he talks about throwing contaminated jars into a big tub of bleach water. I was thinking I could just take the entire tub, lid on and everything as to best contain the mold spores, and lower it into a bigger tub of bleach water. What would be an ideal concentration of bleach for this use?

You're going to need to come up with some sort of long-term solution to this problem.
Is there a vacant lot you can dump tubs into?

However you dispose of it, try not to open it indoors. It will only spread the mold indoors.

If you already have given them reason enough to be looking through your garbage, methinks you have more problems to worry about than contam in your tubs...
Maybe mix in some kitty litter with it (used would be best...) or feces or something to make them think twice about opening it. Or drop it straight off at the waste processing facility and leave no room for meddling.

Actually disposing of it is not a problem - I'll bag it and put it in someone else's dumpster. What I want to know is, how can I minimize the spread of contaminant spores? Even if I dump the substrate into a bag outside, I'll still probably get mold spores all over my clothes and in my lungs, and I'll also still have to bring the empty tub back inside to clean and disinfect it, spreading more spores everywhere I go. So, what I want to do is kill as much of the life that's in the tub as is possible to minimize my own exposure to contaminants BEFORE disposing of it. My original post could have been more clear in this regard.

Throw the entire tub into a bag and toss it out. The tubs are only a few bucks are NOT worth the risk of spores in your lungs or in your house...
It would cost just as much or more to buy bleach than to buy a new tub...

What you propose is terribly wasteful and expensive. Bleach is extremely cheap. I was also looking for other ideas besides bleach.

And the safest way to continue your hobby and life.
Contaminated tubs aren't something you should be dealing with too often in the future anyways, so it's not like every grow you get new tubs. A new tub costs maybe $5 at the upper end of things, and bleach costs what, $10 for a decent size jug? They probably use up close to the same amount of molded plastic, while bleach also has a fairly extensive chemical manufacturing process that the plastic does not so both are relatively equal on terms of waste produced.

Also, besides throwing it out and bleach, there are few to no other ways of getting rid of spores. Short of possible UV sterilization which is even harder to work with an amateur, spores are very resistant things, and large plastic tubs are not the easiest thing in the world to work with.

Suck it up, throw it all out. Get a new tub and save your self the agony of having every single tub from here on out go green because you get stingy and tried to save it. Everyone here seems to argue that it's not worth it trying to save cakes or subs that go under because it's much safer and easier to start over, why would it be different for tubs that are spore ridden?

If by  "bag it" you mean pour the contents in a bag, you should do that outside. In any case, pour a bunch of bleach in it first and let it sit a day. It will kill everything. Safest bet is toss the tub, especially if you can't work outside to clean it.  You don't want to inhale the spores, it's not just an issue of contaminating future grows.

Hence the reason for the thread, reflecting my caution in approaching this issue.

I do agree that there is no need to take chances with health, and I will probably end up tossing the tub as you recommend, especially since I have so many of them.  :chugbeer:

:smile: I didn't mean to come off as rude or an asshole ^.^', just that spores are nasty nasty things to have in ones lungs, and it really is the easiest, safest and arguably the cheapest way to move forward...

As for long term ideas? Don't let tubs get contaminated? I mean... from what I read, Coir is pretty hard to contam at all, yet yours went really quickly. I'd also do some looking into why that might have happened...

I thought that the fact that I created this thread in the first place would spare me all the "oooh you don't want to breathe in spores" jive. If I didn't care about breathing in spores, I'd just go dump the tub out somewhere.

And yeah, I don't know what happened with this tub. I've not had one go south like this before.

I live in the city as well..  But all I do is throw it away in a garbage bin.  Just put it in a bag by itself with nothing else in it.  As long as you don't put like a bill with your name and address in the bag with the substrate, how do they know where it came from ?

Spore analysis. 'They' grow strains of contams like we grow strains of cubensis, and then release tainted prints into the community. :tinfoil:

Respirator, $30 -> http://www.amazon.com/MSA-Safety-Works-817663-Multi-Purpose/dp/B00009363G/ref=sr_1_1?ie=UTF8&s=hi&qid=1257045534&sr=8-1

Get a sufficient sterilizing liquid.  Like 10% bleach or similar (hardware store sells a few different hospital grade cleaners that work just as well).

max up a bottle of that, load up the mask and spray that sucker down good and let it sit.  Once it's all dead and wet so you dont have a bunch of airborne shit, dump/scrape it out into a heavy duty trash bag and dispose of it.

Personally, I just take the tubs and dump them in the woods or around my flower beds/garden, makes great compost.   

I let the tubs sit out in the driveway for awhile (weeks) then clean/re-sterilize when I need them.
