An explanation about our environmental activities that we especially emphasize.

• Introduction of the Photo Voltaic System (PV)


• Converting the boiler fuel to natural gas

At the rooftop of the Wakaho Plant, we generate 30 kW of electricity using two 40-m solar batteries installed side by side. Infinite solar energy is used to generate electricity and reduces the volume of CO₂ emissions. The Photo Voltaic System at the Kurita Sogo Center generates 10 kW, which is used to light the center and the rest is sold.

Our steam boiler systems are being converted from heavy oil to natural gas to be friendly to the environment. The old boilers are being replaced with a high efficiency type during this conversion. We have changed the boiler systems at the Arai plant in 2005 and at the Wakaho, Kyogase, Takaoka plants in 2007. We will make changes at the Kohoku plant in the near future.

The natural gas that the Company uses are obtained from wells in Japan and reduces not only CO₂ when burned but also approximately 50% of the nitrogen oxides (NOx) and nearly 100% of the sulfur oxides (SOx) compared with heavy oil. The price of such natural gas is low and does not fluctuate much, which contributes to a substantial cost reduction.
