Composting

Earlier today I posted to the farming community to ask about a photobash of a village I'm working on. One of the suggestions I'd received in my last search for inputs was a centralized composting solution, which I think makes sense for a solarpunk community. Everybody contributes organic waste and everyone benefits.

I started doing some reading about options from a random state website so I guess you can assume that's the absolute upper limit of my understanding of composting at this time. I just want to represent it well and if there's any good talking points that could go into the picture's text write up to drive discussion, I'd love to include them.

One thing I saw was that with aeration, you can do negative pressure systems which suck air from the compost windrow to pull in fresh air - if you did that, could you divert the compost offgassing (which should be a decent amount of CO2 right?) into the greenhouses to boost the plant growth without burning fuel?

Thanks for any input
