Management of Chemical Substances and
Reduction of Emissions

  When utilizing chemical substances, the Yamaha Group strives to minimize adverse impact on people and the environment by thoroughly managing chemical substances such as those designated under the PRTR*1 Law, and reducing emissions of substances from production processes and products. For these reasons, the Group has launched the Chemical Substances Management and Reduction Working Group (Risk Reduction Working Group from fiscal 2013) as a cross-sectional organization under its Yamaha Group Environment Committee to direct the Subcommittee on Chemical Substances at each of the Group's business sites toward the implementation of specific measures.

  At present, the chemical emissions that occur in the course of production processes at the Yamaha Group mainly consist of volatile organic compounds (VOCs)*2. In fiscal 2006, the Group conducted a survey of the Yamaha Group's usage and emissions of VOCs, followed by the establishment of a reduction plan in fiscal 2008 with a set target of a 30% reduction in emissions by fiscal 2010 compared with fiscal 2000. Yamaha has remained committed to its efforts to substitute or reduce chemical substances throughout the Group.

  In fiscal 2012, a total of 45 tons of substances designated under the PRTR Law were emitted during the course of operations at the Yamaha Group, which was a reduction of 20% from the previous fiscal year. VOC emissions were reduced by 5% year-on-year and by 74% relative to fiscal 2000. The Group has continued to achieve a 30% reduction in VOC emissions since 2008 relative to the fiscal 2000 level. Contributing to these achievements were emission reduction measures such as rationalizing production processes and using alternative materials in addition to consolidating factories, which even included reducing production output.

  Therefore, the Yamaha Group will comply with the standards independently set by the Japan Musical Instruments Association, while continuing to take steps to consistently meet the target for a 30% reduction of emissions compared to fiscal 2000.

  • *1 PRTR: An abbreviation for Pollutant Release and Transfer Register. The PRTR Law is an abbreviation of the Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in Their Management.
  • *2 VOCs (volatile organic compounds): These compounds, contained as thinning agents for coatings and adhesives, are believed to be one factor in the release of photochemical oxidants and suspended particulate matter (SPM).

Environmental Effects of Piano Production Operations

Kakegawa Factory, P.T. Yamaha Music Indonesia and Hangzhou Yamaha Musical Instruments Co., Ltd.

  Using the consolidation of the piano production processes at the Kakegawa Factory as an opportunity to make facility improvements, from fiscal 2010, paint for certain products was switched from an organic solvent based- to a water-based paint.

  The shift was made to water-based coating material for upright piano components in fiscal 2011 and water-based coating material for grand piano components in fiscal 2012. As a result, PRTR designated substances and VOCs emitted from the paint drying process were each reduced by over 2%.

  Additionally, efforts are being made to shift to water-based paint in piano factories overseas. P.T. Yamaha Music Indonesia shifted to water-based paint in the coloring process for a majority of piano components in fiscal 2012 while Hangzhou Yamaha Musical Instruments Co., Ltd. shifted to water-based paint for certain piano components.

  Through the process of using a water-based paint, local ventilation facilities have become unnecessary, contributing to an improvement in the working environment as well as increased energy efficiency.

Reducing Chemical Substance Emissions by Improving Coating Process

  The Yamaha Group administers an array of different coatings to pianos and other musical instruments and automotive interior components, and as such, is committed to devising ways to draw out the maximum beauty of each product and to help ensure it can be used for a long period. We continue to research coating methods that have the least environmental impact, which includes reducing the amount of coating and organic solvent used as well as minimizing emission to the environment. To date, we have developed applications for electrostatic coating, powder coating and flow coater in accord with each product and are making use of them in our production process.

Yamaha Fine Technologies Co., Ltd.

  Yamaha Fine Technologies Co., Ltd. has been steadily employing in-mold coating for automotive interior components since fiscal 2006, and is working to reduce the amount of coating used as well as the amount of emissions of organic solvents into the atmosphere. Previously, coating for products with a three-dimensional configuration had to be atomized as with spray application before being applied. The new method enables the coating to be applied to products in liquid form without atomization.

  In addition, the company newly developed film-forming equipment and clear resin for use with in-mold coating. This facilitated a switch to styrene-free coating, which has resulted in zero emissions of styrene in the coating process. Also, shifting from conventional open spray type coating to sealed in-mold coating has led to coating transfer efficiency of over 90%, which resulted in a reduction in the amount of coating used and emission of organic solvents. A further benefit is the significant reduction to the amount of ventilation required in the workplace, which contributes to energy conservation. Going forward, the company will strive to reduce styrene emissions and save energy by increasing the number of components that employ in-mold coating.
