Conservation of Water Resources

Working to preserve water resources as a precious natural resource

Basic ConceptReducing usage and understanding impact of wastewater on nature

The Sekisui Chemical Group understands that water resources are a vital natural resource that it needs to sustain its business activities. We are making concerted efforts to reduce the amount of water used, survey the impact of wastewater on biodiversity, and understand water-related risks that could impact our business in the future.


FY2016 Performance and Directions for the FutureWater usage reduced by 5.6% to keep usage at the same target level as fiscal 2013

The Sekisui Chemical Group draws the water that it needs to use in its business activities, such as from public water systems, industrial-use water, underground reservoirs and surrounding rivers. With the understanding that water is a precious natural resource on this planet, we do our best to reduce the amount of water used, such as by reusing cooling water.

Under its environmental medium-term plan, the Sekisui Chemical Group aims to keep its water usage (water drawn) at the level in fiscal 2013, which was the end of its previous environmental medium-term plan. In fiscal 2016, water usage was 5.6% lower than the amount used in fiscal 2013.

Beginning in fiscal 2013, we have conducted assessments* of the impact of wastewater on biodiversity around our production plants. In fiscal 2016, we performed these assessments at tthree additional business sites.


* We introduce in more detail our assessment of wastewater's impact on biodiversity on the Natural Environment webpage.

Ongoing Monitoring of Water RisksContinuously Assess Water Extracted from Production Sites and Wastewater Risk

The Sekisui Chemical Group conducted surveys of water risk in order to better understand water risk at its business sites. From fiscal 2014 through fiscal 2015, we surveyed 98 business sites and R&D laboratories around the world to gain a firm understanding of our sources of water, wastewater emissions, current water needs, and future demand for water. In fiscal 2015, we identified 14 business sites with relatively significant water-related risks, and conducted more in-depth surveys. As a result, we now understand there are major differences in water supply volume and water quality by region, although the in-depth survey did not identify any water supply risks, such as a potential increase in costs or restrictions on water sources that would adversely impact production activities. In fiscal 2016 we will promote effective use within our business sites to reduce water intake and continue to release water back into the water environment in the region by maintaining water quality in strict compliance with wastewater regulations.


Water RecyclingRecycling cooling water used for plastic moldings

The Sekisui Chemical Group promotes the reuse of water in its production processes and the use of recycled water in order to reduce the amount of water it draws from water sources. At the production plants of Urban Infrastructure & Environmental Products Company and High Performance Plastics Company, large volumes of cooling water is recycled and reused in manufacturing processes. In fiscal 2016, at production sites in Japan and overseas, we used 108.4 million cubic meters of recycled water, equivalent to 5.3x the amount of water drawn from all other sources.
