Material Flow

The material flow of the plant is shown below for FY2024.

CO2 Emissions Trends

Total CO2 emissions in FY2024 decreased by approximately 21.1% compared to FY2021,significantly exceeding the target.

Measures such as the use of heaters and LNG have also reduced fuel CO2 emissions.

We will continue to promote energy conservation activities in order to achieve our targets for FY2030.

Trends of Water Withdrawal

Although there was a slight increase in FY2024 compared to FY2023, the result was below the average for the past 10 years.

In FY2025, we will focus on analyzing the causes of the increase and implementing countermeasures, and will work even harder to conserve water.

Trends of Waste 

In FY2024, the amount of waste remained flat, but the number of valuables increased significantly, resulting in an increase in the total amount of waste generated compared to FY2023.

We will continue to work on reducing not only the amount of waste but also the valuables generated.

Emissions and transfers of substances subject to PRTR Act

The following figures were taken in FY2024 in accordance with the PRTR Act .

(Act on the Assessmnt of Release of Specified Chemical Substances in the Environment and the Promotion of Management Improvement). 

We will continue to work on reducing emissions in the future.
