What sort of substances end up in leachate, and how'd that contribute to greater CH4 production in your landfill? I was hoping that the OP post/video went into more detail on the chemistry involved.
A wet environment is much better for ch4 generation (was my understanding).
So we had an area that we called "the galleries" where we would rotate injecting the leachate. To keep all that stuff underneath wet (this is in southern ca, a pretty dry environment).
That was the concept anyway.
