[Digestion] Bio methane economy?

[Warren Weisman]

Hey, all, 

The biogas plant we are proposing for Eugene, Oregon
would utilize local crop waste to co-digest with
wastewater and the resultant fertilizer would then go
back out to our local farmers. The captured biogas
would fuel our local transit bus fleet and replace an
antiquated district steam system downtown. 

Unlike hydrogen, biogas has other advantages than
energy generation and this integration is what makes
it superior to other energy choices.
