In accordance with the MITSUBA Environmental Declaration, MITSUBA Group is promoting the creation of a recycling-oriented society and the effective use of limited resources. We recycle and properly treat waste generated from all business activities, and promote technological development such as improving the efficiency of raw materials and downsizing of production equipment to make effective use of resources.
In the plastic molding process, we aim to reduce the amount of runner waste to zero by 2040. We are also actively promoting the reduction and recycling of industrial waste from plastic products by systematically improving processing on a global scale. To further promote the recycling of plastic resources, we are reviewing our waste plastic processing contractors and other initiatives to recycle waste plastic materials.


MITSUBA Group periodically monitors the pollution status of water discharged from our business activities. The water used in the production processes is purified in an advanced wastewater treatment facilities and then discharged into rivers. We strive to protect the marine environment by properly disposing of wastewater that cannot be purified at wastewater treatment facilities as industrial waste.
At our sites in Asia, which have a large water-related impact, we are actively working to effectively utilize water resources and reduce intake by collecting rainwater. MITSUBA India Pvt. Ltd. has introduced a recycling-oriented wastewater treatment system to reuse wastewater from the surface treatment process, making effective use of limited water resources.
