wastewater, exhaust, dust, and other emissions from the power plants to protect the environment in theareas where they are located.

Consideration for the Characteristics ofthe Location Area

Eﬀective Utilization of Waste

The Nakagusuku Biomass Power Plant, located in Uruma City,
Okinawa, uses industrial water instead of seawater for coolingwater used in power generation. Normally, seawater is usedand discharged into the ocean, but the water is sent to asewage treatment plant via a wastewater treatment facility toavoid disturbing the ecosystem of the surrounding sea area
and to preserve the beauty of Okinawa's ocean.

We make eﬀective use of waste materials
by recycling combustion ash from power
plants through industrial waste contractors
for use as roadbed material, soil
conditioner, and other purposes by
granulating and solidifying
