Oki Recycling Center Kururun
Oki Town secures citizen’s cooperation when proceeding with town planning and constructing
a sustainable society, aiming not to leave the problem for the next generation. These efforts
consist of two main projects.
One is a biomass recycling facility called The Oki Recycling Center “ Kururun”, and the other is
Oki Town Mottainai Declaration, the second in the country to make a zero-waste declaration.
Oki Recycling Center Kururun is the biomass recycling facility that started operations in
It takes kitchen waste from the town’s households and restaurants, along with septic tank sludge
and raw sewage, and uses a methane fermentation process to turn it into a biomass that can be
used for power generation. After the fermentation, the digestive fluids are used as liquid fertilizer.
Furthermore, Oki Town was the second in the country to make a zero-waste declaration,
which it officially announced in March 2008 with its Oki Town Mottainai Declaration.
