Doesn't Maker's Mark have a big cesspool they use for methane generation for their boilers? I didn't actually see it but they spoke of it a few years ago on their tour.  I haven't been back since so idk if it's still a thing. 

Regardless, several craft to large breweries (probably close to all?) use secondary fermentation to reduce biological oxygen demand (BOD).  A methane digestor just collects and compresses it at the lowest level but if you are large enough (bigger than DIY) you'll need to scrub  (purify) the gasses.  Note that I have never built one but have talked with several companies and researches on it so I'm just regurgitating info here.
