Bridgestone Corp announced Dec 12, 2013, that its subsidiary started a business of selling electricity generated with solar power generation facilities.

The subsidiary is Bridgestone Plant Engineering (Kodaira City, Tokyo), which designs, manufactures and sells tire manufacturing facilities. On the same day, a ceremony to celebrate the completion of the construction of a solar power generation system took place at Bridgestone's Saga Plant, and the system started operations. In addition, another ceremony is scheduled to celebrate the start-up of a solar power generation system at its Hikone Plant Dec 17, 2013.

The total investment is about ¥1 billion (approx US$9.66 million). The power generation capacity of the two systems combined is about 3,500MWh per year. The installation of the solar systems is part of its efforts to reduce CO2 emissions, which is described in the Bridgestone group's "Declaration for Environment." The group drew up the declaration to clarify the direction of its environmental activities.

The Bridgestone group, which claims to engage in environmental activities as part of its regular business in the aim of keeping itself growing, employed solar panels using only its EVA (ethylene/vinyl/acetate) film. An EVA film is used as an adhesive that fixes the power-generating cell of a solar cell to a glass surface by using molecular binding (cross-linking) triggered by heat.
