[USCC] What is anaerobic composting?

[Myron Hirschman]

I was recently in a meeting discussing composting options for the community.
Their engineer mentioned anaerobic composting as a system.  I didn't have
the opportunity to get that explained to me. I am guessing he meant systems
that didn't have forced aeration ( if that is what he meant I disagree with
his use of the terms).

Please educate me.
