Co-existence with Nature
As an initiative for coexistence with nature (reducing environmental impact on nature), LINTEC works on water conservation (water use, effluent treatment). We pay sufficient attention to water saving, recovery and reuse, compliance with effluent standards, and effluent water quality.
Reducing Water Usage and Effluent
In fiscal 2022, LINTEC used 7,798,000 m3 of water. Of this amount, around 86% was used by the Kumagaya and Mishima plants, which comprise LINTEC’s Fine & Paper Products Operations. In fiscal 2022, water usage per unit of paper production was 46.60 m3/t, which achieved the target of a 1% reduction on a year-on-year basis.
The next target is a 4% reduction per unit of production by fiscal 2025 from the fiscal 2021 level. 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.

Biodiversity Conservation Initiatives
Upholding biodiversity conservation in the LINTEC Group Quality, Environmental and Business Continuity Policy, the LINTEC Group accordingly conducts biodiversity conservation activities in and outside of Japan.
The Tatsuno Plant in Japan maintains and monitors conservation-listed deep-veined maple trees and uses red robin trees for greening purposes.
We will continue to promote the activities in collaboration with external companies.
The Chiba Plant covered the west wall of its warehouse with a green curtain in June 2022. Vines were seen to grow over four meters in length, as shown in the photo in August. We will continue to promote these activities that are close to us.
