That terra preta-stuff, charcoal and you're scrubber..

Hi

Just came up with this retarded idea about recycling the exhausted active carbon from carbon scrubber to be used as soil amendment.

Somehow I assume that it's not that wise, but I'd like to know why

I have thought about the same thing. I could be wrong, but I think the pyrolosis (I could have that wrong) process is maybe different in bio-char than activated carbon. I think I read that somewhere, but I would rather wait to hear from Suby, Clackamas or Volthorne (or whatever the wizards name is). They know their bio-char. I hate throwing out those huge canisters...seems so stupid. If everytime I killed a canister I drilled out the rivets and amended my coco with it...perfect.

Good question, we await the experts...

Checked the stickies for more info or comments regarding active carbon.

Ph-issues and not as good as wood/biochar were what I could get out it. But wasn't sure had they used new or used active carbon, maybe the latter would be better.

The only reason used activated carbon might not be advisable is because it's a collector of all things biological, so the concentrations of things (what things I don't know) might be a little hot, or it might have some pathogens which wouldn't be advisable to put directly into the soil..

I'm pretty sure that if you gave it a bit of time in your compost, it would resolve any issues of that sort.

BTW, it's your scrubber, you're is short for you are, and while I can't speak for everyone, I'm not a scrubber.

Oh, didn't even notice that typo. I'll contact mods so they can correct it.

Sorry, it's the pedant in me..
