Reduction of waste

  • Materiality

Mizuno is making efforts to reduce waste through the life cycle of our products, designing, manufacturing, use and disposal, to prevent environmental pollution and achieve sustainable resource usage.
In addition, the industrial waste discharged from each facility is controlled so that it can be properly processed through checking manifests, periodically checking the site. In order to properly manage industrial waste, major business sites operate and administer by electronic manifest. For many years, we have worked to reduce industrial waste at our production bases. In FY 2018, we reduced industrial waste emissions by 153.3 tons (down 4.1%) compared to last year. By discharging industrial waste after removing water from sludge industrial waste in Senohtech, we were able to reduce about 8 tons of emissions.

Efforts for zero emission

Mizuno is pursuing zero emissions at its domestic manufacturing bases, and promotes the thorough reuse and segregation and total emission reduction of waste, and converts waste into valuable items by sharing information among business sites.
In addition, we started selling extra parts of materials of carbon products as recycled materials that previously used to be disposed of as industrial waste. The clients who purchase these extra materials recycle them into fine shapes and quality carbon fiber at low cost and save energy by using original recycling technology that they have developed themselves.
*Municipal solid waste is not included as a target of zero emissions

“Osaka Plastic Waste Zero Declaration”

Osaka Prefecture and Osaka City, as the venues for the 2019 G20 Osaka Summit and the 2025 Osaka-Kansai World Expo, created the “Osaka Plastic Waste Zero Declaration” that includes the enhanced promotion of disposable plastic reduction and plastic resource recycling. In response, Mizuno made the following declaration and gave consent for this action.

Mizuno's Plastic Waste Zero Declaration

Mizuno promotes plastic waste reduction throughout the value chain. In manufacturing, we promote the use of recycled plastic, and at factories and offices we completely separate waste and recycle waste plastic into solid fuel and a variety of components. In stores, simple packaging is recommended to reduce waste. At the Osaka Head Office, we also conduct clean-up activities in the Cosmo Square area and Yamatogawa riverbed in cooperation with Kansai University, contributing to waste reduction as a member of the community.

Future issues to be addressed

  • We will focus on not only the cost of the manufacturing process but also the reduction of waste from the product planning stage so that we can reduce packaging materials and packages.
  • Until now, we have been making efforts to reduce waste mainly at production bases, so we will make efforts to reduce waste by deploying the expertise we have developed from the activity in the past into non-production bases, which have a large amount of waste.
  • We will promote the introduction of the electronic manifest to the Senoh Group, which was unable to begin the operation
