Anaerobic Composting

Last year, i started investigating a different way to compost.  We have used many different kinds, including standard bins that are turned with a pitchfork, bins that turn with a handle, and worm bins.
I wanted something that was affordable and fully enclosed.  I haven't had trouble with rats, possums, and coons in the compost, but they are around.  I don't want to give them any more encouragement to hang out here.
So i came to anaerobic composting, which was new to me.  I guess i hadn't really given it any thought before. Anaerobic composting requires a different set of conditions and organisms than the conventional aerobic. They thrive in an environment completely lacking oxygen.

So i sold the rusty Compost Tumbler and worm bin on Craigslist and we bought some metal garbage cans.

These are the instructions we used.  "WE" means i find the plans and Justin makes it for me.  I always dig the holes though.
