Waste Reductions

We’re committed to reducing waste volumes by avoiding use of unnecessary resources and resource waste in production processes.
We’re also promoting reusing and recycling by making effective use of waste as resources to achieve zero emissions (final disposal ratio of 0.2% or less).

Zero Emissions from Waste

  • At offices in Japan, we’re promoting various actions with the goal of achieving zero emissions from waste. In fiscal year 2019, we continued reusing plastics, useful metals contained in sludge as valuables, and pallets. Despite these efforts, the final disposal ratio* was 0.34%. We were unable to achieve the target (not more than 0.2%) for the second straight year.
    This was due to the disposal of refractories (debris) generated during the maintenance of a metal melting furnace. In and after fiscal year 2020, we plan to take action to achieve further reductions with the continuing target of zero emissions.

Reduction of Waste Volumes

  • Reduction of Emissions/Production (Domestic Offices)

    At offices in Japan, we’re committed to reducing emissions (excluding the directly recycled amount)/production and striving to achieve 4% reductions from fiscal year 2016 by fiscal year 2030.
    In fiscal year 2019, we achieved 10% reductions from fiscal year 2016.
    Due to the rebranding to HiKOKI (October 2018), we disposed of various stock and service parts, increasing both waste volumes and intensity from the previous fiscal year.
    In and after fiscal year 2020, we plan to reduce emissions to achieve the target.

  • Reduction of Emissions/Production (Overseas Plants)

    At the plants outside Japan, we’re committed to "reducing the emissions/production."
    In fiscal year 2019, we achieved 13% reductions from fiscal year 2016.
    In and after fiscal year 2020, we plan to strive to reduce emissions and achieve the target.

Promotion of Battery Recycling

As a member of the Japan Portable Rechargeable Battery Recycling Center (JBRC), the Koki Holdings Group has set up collection bases at Koki power tool centers throughout Japan.
We’re actively collecting and recycling used batteries by distributing and displaying our unique posters at dealers across Japan.
