Efficient Use of Resources

Resource Recycling

Punched residue collected for recycling

We use tens of thousands of tons of steel to manufacture motor housing (motor case) parts. The steel material is made into parts by press working through processes such as punching and drawing. From the viewpoint of efficient use of resources, we aimed to improve the material yield rate, minimized the punching width due to the difference in material thickness and material, and reviewed various processes such as feed accuracy in press working. As a result, the material yield rate has improved by 5%. In addition, 100% of the scraps generated during press working are reused.

Reuse of waste heat at overseas bases

The hot water supply system at Dalian Mabuchi and Wafangdian Mabuchi in China has been changed to a system that can recover and reuse exhaust heat. By using hot wastewater and air-conditioning exhaust heat, power consumption has been reduced by more than 80% compared to hot water supply using only electricity.

Reuse of waste heat at Headquarters

Our Headquarters building was built based on Mabuchi Group's Basic Environmental Policy which aims to make the best use of limited resources. By adopting state-of-the-art technologies and methods such as a double-skin structure to minimize heat load and a building-frame thermal storage, the building is well equipped to allow proactive pursuit of energy savings and has achieved more than 20% reduction in life-cycle CO2 emissions compared with buildings of similar scale with standard facilities. emissions over the building's life cycle compared with those of standard facilities.

Initiatives for Sound Water Management

We are actively using rainwater to cherish water resources. The Headquarters has been using rainwater since 1991, and each base in the group is also actively using rainwater.
In addition, at each base in the group, including Jiangxi Mabuchi, wastewater treatment facilities have been constructed in the factory, and part of the water treated here is reused for planting water and toilet water.

Waste Reduction Initiatives

Weste emissions

We have set a goal of achieving a waste recycling rate of 95% or higher, aiming to realize a recycling society that recovers and reuses waste as a resource and reduces the amount of waste sent to landfills. In addition to reducing the amount of waste itself, the reuse of waste as a resource is an important and indispensable part of realizing a recycling society. The entire Mabuchi Group will continue to promote initiatives to reduce and reuse (recycle) waste.

Indicators for Waste Reduction and Initiatives for 2022

[Target] Waste recycling rate: 95.0% or more

[Achievement] Waste recycling rate: 98.7% (achieved).
             ● Conducted "Awareness Training on Waste Separation and Reduction" for the Headquarters
             ● Started counting the amount of recycling when thermal recycling is not included

Thorough Separation

Panel showing how to dispose of waste by type

Separation of waste is essential for recycling. To promote thorough separation that is easy for everyone, we post signs on separation in prominent locations and establish places for people to leave wastes.
For disposal of motor materials as resources, parts are separated by type of material and processors are selected for each material. While we have contracts with two recycling companies in Japan, some materials at overseas factories cannot be recycled and we are trying to find processors for these.

Efforts in Headquarters

Environmental measures in the construction of the parking structure for employees

Parking structure for employees (Headquarters)

In the construction of a parking structure for the employees of Headquarters, we reduced about 8 tons of CO2 by using LED lights, of course, and also by reducing the use of wooden molds, scaffolds, and excavation soil as environmental measures in the construction phase.

Recycling of Waste

Composting process for fallen leaves and small branches

Since fiscal 2006, Headquarters has been working to recycle food waste, cultivating recyclable suppliers, and continuing to use food waste as feed and compost. As a result, 100% of the garbage generated at Headquarters can be recycled. In addition, 100% of the leaves and twigs on the premises of the head office are recycled by composting them.

Efforts in Factories

Reducing Waste in the Production Process

Simplified wastewater treatment equipment

The tip of the motor shaft (*) is chamfered. We have reviewed the polishing method and switched to a forging method to reduce industrial waste and simplify wastewater treatment facilities.

  • *Shaft : an important part that takes out rotation output from the motor and transmits the power to the unit.

Efforts in the Logistics Field

"Returnable containers" which can be used repeatedly

In the logistics field, we are working to reduce waste by promoting the recycling of polystyrene packing materials used to deliver products to customers and the use of reusable returnable boxes. In addition, in order to reduce the amount of CO2 generated during the collection and transportation of recycled packaging materials, we are promoting the construction of a collection processing system in Japan as well as in locations near our customers.
