Around the world, manufacturers are rethinking how industry can grow while protecting the environment for future generations. For Tungaloy Corporation, this balance between innovation and responsibility has guided its Think Green initiative, a programme 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 manufacturing 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.
Tungaloy obtained ISO 14001 (for environmental management) in 1997, becoming the first in Japan’s cemented-carbide tool industry to do so. In 2024, the company’s Iwaki headquarters added ISO 50001 (energy management), reinforcing a management approach that combines quality, safety and energy efficiency.
Since 2022, the Nagoya Campus has operated entirely on electricity from renewable sources. At Iwaki, solar panels installed in 2015 generate about 160 MWh annually, reducing the plant’s CO₂ footprint by approximately 75 tons every 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.
In both 2024 and 2025, Tungaloy received the Environment Grand Prize from the Japan Cutting & Wear-Resistant Tool Association, acknowledging the company’s long-term environmental efforts. Tungaloy sees these awards not as a contest, but as a reminder of the shared responsibility to advance sustainability across the manufacturing sector.
