There are red buildings that house some 4,000 cows, a staggering manure pit, and two gigantic dome-like structures that serve as anaerobic co-digesters. These giant machines break down manure and local food waste to produce biogas. This renewable natural gas, or RNG, is then typically transported for use as electricity, heating, and fuel.
