For Tungaloy Corporation, this balance between innovation and responsibility has guided its Think Green initiative, a program focused on real, measurable actions to reduce environmental impact and contribute to a more sustainable society.

In 2025, Tungaloy continued to move forward with this commitment, expanding renewable-energy use, introducing green hydrogen in production, and strengthening product design through environmental certification standards. These efforts reflect the company’s belief that lasting progress comes from genuine collective responsibility, not simply from meeting compliance requirements.

Sustaining Improvement Through International Standards
Tungaloy obtained ISO 14001 (Environmental Management) in 1997. In 2024, the Iwaki Headquarters added ISO 50001 (Energy Management), reinforcing a management approach that combines quality, safety, and energy efficiency.

Renewable Energy and CO₂ Reduction
Since 2022, the Nagoya Campus has operated entirely on electricity from renewable sources. At the Iwaki Headquarters, solar panels installed in 2015 generate about 160 MWh annually, reducing roughly 75 tons of CO₂ each year.

Within its own operations, Tungaloy has taken additional steps to lower emissions: in 2023, Iwaki switched from kerosene to city gas, cutting emissions by 27 % in 2024, while the Nirasaki Campus introduced locally produced green hydrogen, reducing a further 300 tons of CO₂ annually.

Together, these measures advance the company toward its goal of a 46 % reduction by 2030 (compared with 2013) and carbon neutrality by 2050.

Environment-Conscious Product Development
All new Tungaloy products are evaluated under the Japan Cutting & Wear-Resistant Tool Association Standard for Environment-Conscious Products (ECP), Japan’s official framework promoting sustainable cutting tools. Each product is rated on a 100-point scale (60 points for product concept and 40 for corporate environmental activities):
• 80 points or above ☆☆☆
• 79 – 60 points ☆☆
• 59 – 40 points ☆
• Below 40 points – Not certified

Several of Tungaloy’s flagship product lines; including the DrillMeister and DrillForceMeister exchangeablevhead drilling systems, the PVD grade SH7025 for precision small-part machining, and other innovative solutions have earned two- and three-star certifications. These achievements demonstrate Tungaloy’s dedication to designing products that combine performance with environmental awareness.
