Otsuka Pharmaceutical Factory, Inc. (Head Office: Naruto, Tokushima, Japan; President and Representative Director: Shinichi Ogasawara), a subsidiary of Otsuka Holdings Co., Ltd. (Head Office: Chiyoda-ku, Tokyo, Japan; President and Representative Director, CEO: Tatsuo Higuchi), has introduced a cogeneration system*1 facility that contributes to reducing CO2 emissions and stably supplying pharmaceuticals to its Naruto Factory on the premises of the head office.
The Naruto Factory's cogeneration system facility uses natural gas as fuel to generate power and uses the waste heat produced during the power generation to produce steam and hot water. With the introduction of the system, further improvements are expected in energy-use efficiencies, and the annual CO2 emissions at the Naruto Factory can be reduced by approximately 1,500 tons. This is equivalent to approximately 5% of the annual emissions of the Naruto Factory.*2 In addition, the boiler fuel was converted from heavy fuel oil A*3 to LNG*4 in September last year, and along with the introduction of this facility, the CO2 emissions are expected to be reduced by approximately 4,800 tons, which is equivalent to approximately 17% of the annual CO2 emissions of the Naruto Factory.*2
The Otsuka Group has identified climate change, resource circulation, and water conservation as CSR Materiality for developing environmental initiatives. Regarding climate change, with the goal of reducing CO2 emissions by 50% by 2030,*5 the entire Group is united to actively promote initiatives such as efficient energy use and conversion to fuels that have less environmental impact.
This facility is also excellent for disaster resistance, such as earthquakes, and is a BCP*6 response facility that allows for continued production of pharmaceuticals through the use of in-house power generation during blackouts. As a leading company in IV solutions in Japan, we will continue to strive to provide a stable supply of products.
Based on the corporate philosophy of "Otsuka-people creating new products for better health worldwide," the Otsuka Group is dedicated to contributing to the health of people around world. We will also aim to contribute to the realization of a low-carbon society and eventually a sustainable society in collaboration with each group company.
