Absorbing and Storing Carbon Dioxide by Expansion of Forestry Area

Trends in Greenhouse Gas (GHG) Emissions

The Daio Paper Group aims to achieve carbon neutrality by 2050 and has set a target of reducing carbon dioxide emissions in FY2030 by 46% compared to FY2013 levels. We are currently preparing for information disclosure based on the TCFD recommendations. One of the three coal-fired boilers at our Mishima Mill will be shut down by FY2030. We subsequently plan to utilize biomass and waste-derived fuels to continue lowering our dependence on coal.

Air Quality Data

Water Quality Data

[COD] Chemical Oxygen Demand: The amount of oxygen required to decompose organic contaminants into carbon dioxide, and signifies the total amount of organic material in the sea. The higher the value, the higher the amount of pollution.

[SS] Suspended Solids: Refers to solid particles suspended in water. The higher the value, the more cloudy the water is. This is a cause of sediments in water bodies.

Initiatives of Daio Paper Group Companies

Promoting the Use of Biomass Fuels

We are engaged in group-wide activities to convert to biomass fuels with lower CO2 emissions.

The Daio Paper Group continues to introduce biomass boilers fired by fuels derived from waste materials, such as woodchips, paper trash, refuse plastic fuel (RPF), and waste tires. As a result of promoting group-wide conversion from boilers fired by fossil fuels such as coal and heavy oil to boilers fired by non-fossil fuels (biomass energy), the biomass energy ratio of the Daio Paper Group increased from 37% in FY1990 to 50% in FY2019.

Promoting the Use of Renewable Energy

The Daio Paper Group is reducing its CO2 emissions by installing solar power facilities as a part of its environment activities. Iwaki Daio Paper Corporation is working to deploy renewable energy sources with low environmental impact. The company began operating a solar power facility at the end of November 2014 in line with reinforcement of its containerboard production facility, which was relocated and rebuilt in August 2014. In 2020, the facility generated 241 megawatt-hours of electricity and reduced CO2 emissions by 110 tons. The Fukushima Factory of Elleair Products Co., Ltd. installed a solar power facility on the roof of its warehouse with support from Fukushima Prefecture’s business siting assistance subsidy and started operations in January 2017. For the year, it generated 53 megawatt-hours of electricity and reduced CO2 emissions by 27 tons. The solar power facility at Otsu Paperboard Co., Ltd.’s Ishiyama Distribution Center generated 268 megawatt-hours during the year, which reduced CO2 emissions by 91 tons.
