Vermicomposting, worm bin, composting with worms community and forums
I've been looking for a while for some large barrels to make a compost tumbler, rain barrel, and flow thru. They're really hard to come by around here and I've found a source but they once contained automotive soap. What are peoples thoughts on using them for the purposes I've mentioned? Can they be cleaned and is there a way to test if they are safe for use?
Thanks to all for any advice and opinions on the subject!
I don't know that they would be safe but they should be clean ;-)
Sorry it was too easy.
I've had luck on Craigslist with food grade barrels.
Thanks for the laugh Keith. Too true!
Jason, I'll try that. Thanks for the suggestion.
You could use the barrel that had automotive soap for a non worm compost bin first. IMO it would season it?
Then use it as a worm bin.
That's a thought Paula... however the seller has not responded to my interest.
I think I've found source of food grade barrels from the local dairy producer. I've yet to speak with them directly, but it looks promising. I'll not find out until Tuesday. Monday is a holiday here.
Thanks to all for your suggestions!
I found this explaination at survivalblog.com:
"The "food grade" designation is determined by plastic purity by and what mold release compound is used in the injection molding process--not by the plastic itself, since all virgin HDPE raw material is safe for food. For paint and other utility buckets, manufacturers sometimes use a less expensive (and toxic) mold release compound. For food grade they must use a more expensive formulation that is non-toxic. Unless the buckets that you bought are are actually marked "food grade", (or, marked "NSF", "FDA", or "USDA" approved), then you will have to check with the manufacturer's web site to see if they make all food grade buckets."
I'm not sure what effects non food grade plastics have on worms but I fairly certain that automotive soap containers do not have to be food grade certified.
Hope this helps
