Environmental Measures and Green Procurement for Products

We believe that the environment must be taken into consideration during the entire life cycle of a product, from procuring materials and parts, to disposing of the product. We continue to develop new models of products with an even lower environmental burden. For example, one of the criteria we use when performing new product development reviews requires that new model of a product to have a lower environmental burden. In addition to reducing the power consumption, size, and weight of products, we also develop new models that allow us to aggregate the functions of multiple machines in a single unit to more efficiently do machining work. In this way, we are working toward reducing the environmental burden of new products, including CO₂ emissions. We also continue to reduce or outright stop the use of hazardous chemical substances, and actively promote the procurement of parts and materials with a lower impact on the environment.

Develop new models of products that emit 30% less CO₂ by fiscal year 2030 (compared with fiscal year 2018)

Reducing coolant pump power consumption

Reduction: Electricity expenses [440,000 JPY]/10 years, CO₂ emissions [12.5 t]/10 years(*)

* Machine operated 16 hours per day, 240 days per year, at a cleaning ratio of 30%: Calculated using electricity expenses of 15 JPY/kWh and CO₂ emissions coefficient of 0.424 kg/kWh

Reducing the frequency of [chip cleaning work] by operators, and preventing injury

　

Reducing the frequency of regular [cleaning work] for coolant tanks

Cleaning a coolant tank requires a lot of work and can also be dangerous. Reducing the frequency of cleaning can prevent injury, and can also help to improve working environments and improve motivation.

In many cases, waste coolant is disposed of by burning it. However, a zero-sludge coolant tank keeps the inside of the tank clean at all times, allowing coolant to be used longer. This reduces how often coolant must be exchanged, which also reduces the total amount of CO₂ generated by burning coolant waste.

Reducing the amount of CO₂ emissions due to [burning coolant waste]

Reduction: CO₂ emissions [40.8 t]/10 years(*)

* Entire tank capacity (700 L) changed once every four months: Calculated with an emission coefficient of 2.92 tCO₂/t when burning waste coolant

　

Reducing environmental burdens by efficiently gathering mist and reducing the frequency of maintenance

Reducing unneeded standby power consumption and utilizing efficient machining programs to shorten machining times and reduce power consumption

DMG MORI views environmental conservation as a priority in all aspects of business, and operates under a management philosophy of "conserving environmental resources to protect the environment." We prioritize items and services with a lower environmental impact when procuring the raw materials, parts, and equipment we use, while also promoting green procurement (such as not using hazardous chemical substances and purchasing raw materials with a low environmental burden) in our efforts to reduce the environmental burden of our business.
