Here is one way I'm stacking functions here at our farm.

I finally got the #biogas system up for this year, and it's starting to bubble away and I'm finally got enough pressure to supply a trickle of gas. I haven't tried to ignite it yet.

This is the Homebiogas 4 anerobic digester.

I've been feeding it cow and pig poop.

The "main" output is biogas, but the other output is this effluent rich in microbes (in the 5 gallon bucket), which goes into the worm bin for production of worms and castings.

I'm hauling the effluent to the worms by hand every couple days, but I set up the anerobic digester purposefully uphill of the worms so eventually I can gravity feed the effluent to the worms automatically.

I have been watching these for awhile, I’d be interested in any updates on how it works for you. Was USDA zone are you in for context any concern for winter slowing down too much.

Will do.

We are in zone 6. I drain about 1/3 of the water out in the winter. It will freeze the way it is exposed.

The eventual plan is to build a greenhouse around it so I can keep it running over winter.

I know there are 3 different families of methane producing bacteria that operate at different temperature ranges so the more consistency the better.
