The biogas system of the Ooki Machi: Facilities were in the center of the town.

The other day, I visited the biogas system of the Ooki Machi, Fukuoka Prefecture.
It is a methane fermentation system.
Electricity is generated by the methane that is generated from the blend of raw garbage and the raw life night soil and the septic tank dirt.
Facilities were in the center of the town, and there was no smell at all.
I was surprised at a clean environment.
