The garbage biogas electric generation center that opened in July, 2013 in Nagaoka City is the nation's largest municipality-run garbage disposal plant (handling 65 ton/day).
The plant is an advanced model plant, which means it can perform methane fermentation with garbage collected in Nagaoka City. It also uses biogas for methane fermentation to generate electricity, which makes efficient use of the fermentation residue.
The Nagaoka garbage biogasification business is a PFI (=Private Finance Initiative). Nagaoka Biocube, therefore, is what is known as an SPC (=Special-Purpose Company), handling design-build and operate-maintenance projects.
