In fiscal 2021, Lintec used 7,718 thousand m³ of water. Of this amount, around 87% was used by the Kumagaya and Mishima plants, which comprise Lintec’s Fine & Paper Products Operations. In fiscal 2021, the water usage per unit of paper production was 50.43 m³/t, which achieved the target of a 1% reduction on a year-on-year basis.
The target in fiscal 2022 is a 1% reduction per unit of production from the previous year. To achieve the target, the plants will make continued efforts to reduce water usage and effluent discharge in each process and prevent water leaks. Moreover, plants that have paper machines are regulated by the Water Pollution Prevention Act. Additionally, the Mishima Plant, sited alongside the Akanoi river in Ehime Prefecture, is regulated by the Act on Special Measures for Conservation of the Environment of the Seto Inland Sea (Seto Inland Sea Act), while the Kumagaya Plant, situated next to the Arakawa river in Saitama Prefecture, is regulated by the Saitama Prefectural Ordinance for Environmental Preservation. Both satisfy effluent standards in their region.

Water usage data is calculated by source.

• Notes: Water usage data is the sum of the figures for tap water, industrial water, and groundwater.

The total amount of water used by Lintec in fiscal 2021 was 7,718 thousand m³. About 87% of this was used at the Kumagaya and Mishima plants. These plants are working to reduce their water usage and effluent discharge by taking measures such as reusing used water in each paper making process. They will continue to renovate the water treatment facilities.

VOICE My Next Stage

Mishima Plant selects pulp according to the purpose, mixes the pulp with water in a tank, processes the mixture with a defiberizer^*1 and a beater^*2, adds chemicals and color to it, and sends it to a paper machine. As the second stage of this process requires a large amount of water, we collect water from the paper machine's dehydration process as well as drain water^*3 produced as a by-product of steam generated during the drying process for reuse in mixing with pulp. Thanks to these efforts, in fiscal 2021, the amount of reused water came to 562,552 tons, contributing to saving water equivalent to 59.7% of the total water volume. We also minimize the amount of water used when cleaning the inside of the tank. We will step up our water-saving efforts in cooperation with related departments.
