Japan: Natural gas and geothermal energy instead of electricity
At our site in Japan, we're working toward reducing dependence on electricity. After the devastating tsunami destroyed the Fukushima nuclear power plant in 2011 and caused a nation-wide power shortage, we completely realigned our energy concept in Japan.
Our site in Onahama, Japan is one of the highest energy consumers within our company, requiring a great deal of steam for pigment production. To make our manufacturing processes more sustainable, we switched process steam generation for production from kerosene to natural gas combustion, and our pigment kilns are now fired with natural gas instead of liquefied gas. These changes will reduce CO2 emissions by approximately 3,200 metric tons per year. In 2016, we modernized other sites as well. At our Shizuoka site, for instance, we switched from heavy oil to natural gas for steam generation while also revamping the boiler and conduit system. In doing so, this site cut back its CO2 emissions from the manufacture of high-tech chemicals for the microchip and display industry by approximately 850 metric tons per year.
