Resources are finite and are the common property of mankind. Based on this thinking, Mabuchi is striving to save on resources and energy.
Efficient Use of Water Resources

In order to conserve water resources, Mabuchi Group is actively using rainwater. Since 1991, Head Office has been using rainwater, and in recent years each company in Mabuchi Group is also actively using rainwater.
Dalian Mabuchi has built a facility for collecting rainwater and has been using collected rainwater in production processes instead of tap water.
Moreover, Jiangsu Mabuchi, Dongguan Mabuchi, Dalian Mabuchi, and Guangdong Factory 1 of Hong Kong Mabuchi have built waste water treatment facilities in their factories and have been reusing part of water treated in the facilities for sprinkling plants or for flushing the toilets.
Improvement of Yield Percentage in Press Working
Punching scraps collected for recycling
Every year Mabuchi is using several tens of thousand tons of steel for manufacturing motor housing (motor case) parts. The steel goes through processes such as punching and drawing by press working, and then it is made into parts.
From the viewpoint of efficient use of resources, Mabuchi had aimed at improving the yield percentage of the material, minimized punch-out width based on differences in material thickness and quality, and reviewed various processes on feed accuracy and the like in press working. Consequently, the yield percentage of the material has improved by 5%. Moreover, punching scraps caused by press working are 100% recycled.
Reduction of Electric Power Consumption

The reduction of electric consumption cuts CO2 emissions, so this is a major goal for us.
We have achieved large-scale improvements, including the consolidation of production plants and the reorganization of production areas. In addition to such large-scale improvements, we intend to keep working toward even minor improvements.
At Jiangsu Mabuchi, a special heat insulating layer was formed on the roof of the employee's cafeteria to reduce electric power consumption.
Vietnam Mabuchi installed sprinklers to spray rainwater over the roof of its restaurant in order to reduce electricity consumed to air condition the cafeteria. Use of the sprinklers has made it possible to lower the indoor temperature of the cafeteria by about 5 °C, saving about 143,000 kWh of electricity per year.
