Measures to reduce environmental impact

Overview of environmental impact

We’re striving to ascertain and lessen the environmental impact of production activities as a whole.

  • The data shown below are for the four plants (the Osaka Plant, Nara Plant, Tokyo Plant, and Ibaraki Plant) and the headquarters and sales groups.
Overview of environmental impact

CO2 emissions intensity

CO2 emissions intensity refers to the volume of CO2 emitted from a fixed amount of business activities. We calculate CO2 emissions intensity based on processing at domestic plants, for headquarters, and for all plants and sales operations in Japan. This is used as a general indicator of energy conservation because it is unaffected by changes in sales or production volume.

Quantitative changes

The headquarters, sales group, and the four plants are striving to reduce CO2 emissions in various ways, including energy conservation activities and the adoption of high-efficiency equipment. They’re also working to reduce industrial waste and boost recycling rates.
CO2 emission increased in FY2022 due to increased processing. As a result of efforts to improve efficiency in the logistics division, company-wide CO2 emissions intensity has been lowered. Industrial waste emissions have also been reduced, and our recycling rate was maintained at 99.7%.

Appropriate management of chemical substances

The chemical substances we use in manufacturing processes are suitably managed pursuant to the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management.Thereof (PRTR Act). In addition, in bag and carton production, we are making steady progress on switching to safe adhesives free of restricted chemical substances. In FY2022, we reduced the volume of substances subject to the PRTR Act by 13%.

Volumes of Type I designated chemical substances under the PRTR Act (total for all four plants)

Putting water resources to more effective use

The water used at the Tokyo Plant for washing printing ink, paint, and adhesives in the manufacturing process is recycled using a water treatment facility for use as toilet flushing water. This helps conserve tap water and counters water shortages by making more efficient use of our limited water resources.

Eco-friendly printing ink

We offer a full lineup of eco-friendly printing ink for use with packaging materials. This makes it possible to contribute to a carbon-zero society by switching from ordinary inks, made using petroleum-based compound resins and organic solvents, to inks made from biomass materials and water-based inks that use no organic solvents.

Eco-friendly printing plastic bags

To reduce use of petroleum-based compound resins in plastic bags, we’re expanding our lineup of biomass materials. We currently offer 13 types of products that have earned biomass mark certification from the Japan Organics Recycling Association.
In 2020, we sold 109,699,707 biomass mark certified plastic bags.

Participation in CLOMA

There are calls worldwide to promote efforts to identify solutions for the issue of ocean plastic waste, a new issue recognized on a global scale. In response, the Japan Clean Ocean Material Alliance (CLOMA) was launched in January 2019 to promote innovation by strengthening joint efforts among a wide range of parties across industry boundaries and by pooling their technologies and expertise. Since then, we’ve participated in CLOMA’s activities as a core member, mainly by proposing use of paper materials as alternatives to plastic products. We plan to maintain our efforts in related areas, including developing new eco-friendly packages and building systems to help realize a circular economy by exchanging information and working with other CLOMA members.
