Effective Resource Utilization (Water Resources)

Effective Resource Utilization (Water Resources)

Fundamental Policies

The Oji Group strives to reduce water intake by improving operation and water recycling and identifying regions with high water-related risk. We also incorporate water intake and water intake intensity taken into our annual plans and carry out regular management. We will continue to promote Group-wide initiatives for the effective utilization of water resources and the reduction of water intake.

Targets

-Reduce water consumption intensity (unit per production)
-Reduce by 6% or more compared to FY2018

Water Resources

Assessment of water risks

The Oji Group uses WRI Aqueduct*1 to assess water risks in projects, new business, and existing business. In existing businesses, the Group identifies relationships between water stress levels and water resource inputs at all manufacturing sites of consolidated subsidiaries.
Water consumption in areas with low water risk accounts for 99% in total water consumption and for 98% in total production.
The paper and pulp business accounts for 84%, and the corrugated board processing business accounts for 15% in total water consumption in these areas.
On the other hand, water consumption in areas with high water risk, there is no pulp manufacturing and mainly paper processing manufacturing, and paper processing manufacturing account for 1% in each total water consumption and total production.
The Oji Group is implementing PDCA by incorporating the reduction of water resources into the ISO14001 target, including areas with high water risk.
Each business site is continuously working on water recycling, stable operations, and efficient water use in order to reduce water intake and consumption. Costs associated with water risk reduction in fiscal 2020 were 6,056 million yen, and investments including research and development costs were 675 million yen.

Reduction Target of Water Intake Intensity and Results

The FY2019 target for water intake intensity, which was a 1% year-on-year reduction, was not achieved partially because of the water intake for the equipment and other construction work that was unaccompanied by production. The water intake intensity was reduced by 5.9% relative to FY2013, the reference year, achieving 84% of the target reduction in the final fiscal year.

In FY2019, the cost of reducing water risks was 6,870 million yen and R&D investments were 1,095 million yen.

Water Intake and Intensity

Reduction of water intake and status of effective utilization through recycling

The Group takes measures to effectively use and reduce water intake at manufacturing sites. Measures to reduce use of tap water include installation of water-save faucets at business sites and headquarters departments.

Water Consumption and Water Recycling Rates

Water recycling

Oji Group companies engaged in the pulp and paper business use a large amount of water. They reduce water intake by recycling water that has been taken in and reusing it inthe manufacturing process. The water recycling rate exceeds 90%.

Recovery and effective utilization of cooling water

Oji Fibre Solutions (New Zealand)

New installation of water treatment facilities that enable recycling of previously unused wastewater generated in various manufacturing processes and other measures.

Through water recycling and water saving efforts, the Oji Group purifies water after it has been used in various treatment processes and returns 95% of the water taken to rivers and the sea. Water consumption is as follows:
