Reducing Environmentally Hazardous Substances

Introducing corporate efforts to reduce use of environmentally hazardous substances

Reducing Environmentally Hazardous Substances

Reducing PRTR*1 Substances

In accordance with various countries’ regulations, the Yamaha Motor Group tracks and reports the content of chemical substances that may be harmful to human health or the environment in the waste materials it generates or discharges. More than 99% of the PRTR substances released by Yamaha Motor are VOCs*2, most of which are generated in painting processes.

In 2013, we upgraded the painting booth at our main Iwata Factory, which now uses low-VOC paints. The new engine parts line set up in 2015 uses a smaller volume of painting materials as it has adopted a robotic painting booth that features the latest airflow control system. At other factories, as well, we are reducing VOC emissions through optimization of the paint robot system and other means.

We plan to continue reducing VOC volumes by promoting expanded use of low-VOC paints, improving coating efficiency, and reducing paint volumes.

Managing Environmentally Hazardous Substances at the Manufacturing Stage

Yamaha Motor manages environmentally hazardous substances emitted from its factories in accordance with relevant laws and regulations, and is working to reduce its emissions of these substances by adjusting conditions for the operation of equipment to curtail the creation of nitrogen oxides, improving heat efficiency to reduce fuel consumption, and switching to low-nitrogen and low-sulfur fuels.

Reducing environmentally hazardous substances used for products

As countries have increasingly regulated the use of environmentally hazardous substances over recent years, the number of regulated substances has increased. The Yamaha Motor Group is responding by steadily developing environmental management activities at factories overseas as well as in Japan.

For example, we handle some of the products that fall under the scope of the revised RoHS Directive* regulating the use of certain substances in electrical and electronic equipment in Europe; therefore, we are preparing to comply with the Directive before the revised restrictions come into force on July 22, 2019.

Furthermore, in the United States, in response to the revision of warning label rules under Proposition 65 in California, we are switching to warning labels based on the new rules by August 30, 2018 concerning chemical substances contained in products marketed in California.

Going forward, we will work to share information from across the entire supply chain, while systematically reducing the use of environmentally hazardous substances and pursuing alternatives.
