Reduction of Waste

Initiatives at Plants

As well as making our utmost efforts to curb the volume of waste generated through business activities that we discharge, plants are working to reuse and recycle resources and to reduce the amount of waste that needs to be disposed of (non-recyclable waste).
In FY2022, we reduced the total volume of discharged waste, such as waste ink/solvents/plastics and sludge, by 3.7％ to 1,802t from 1,872t the previous year. With a recycling rate of 99.8％ (Material recycling: 47.0％, Thermal recycling: 52.8％), the 4 domestic plants (Tokyo, Osaka, Shiga, Hanyu) achieved a recycling rate of over 99.5％ (zero emissions). Going forward, we will separate waste and continue to achieve zero emissions, while also working to reduce the amount of discarded plastic waste set as a target from FY2023.

Initiatives at non-production facilities

The head office recycle rate (Osaka/Tokyo) in FY2022 was 99.2％ (Material recycling: 88.2％, Thermal recycling: 11.0％). When starting these activities, we first investigated the waste disposal situation and put separate recycling bins on each floor before taking actions including holding meetings and undertaking a survey of the state of separation, building a system for cooperation with the building management company, bringing in environmentally friendly shredders, and changing separation rules. We will continue our activities with the aim of increasing our recycle rate.

Initiatives by Overseas Affiliates

Production facilities at overseas affiliates are working to secure ISO14001 certification, as well as on other things such as the proper management of waste disposal.
In FY2022, waste such as waste containers/plastics increased, and the amount discharged was 8,407t - a 4.0％ increase from 8,087t the previous year.
