Conserving the natural environment

We strive to maintain natural environments and biodiversity.

Basic ConceptLessening the impact of business activities on biodiversity

Approach to Maintaining Biodiversity

In April 2008, the Sekisui Chemical Group incorporated items on biodiversity in its Environmental Management Policy. In 2011, the Sekisui Chemical Group created its Environmental Guidelines, and has strived to maintain the natural environment, including biodiversity, through both environmentally conscious business activities and taking action to preserve the environment.

Initiatives Envisioned under Biodiversity Guidelines

 

Initiatives to Improve Green Space QualityInitiatives to improve green space quality at all domestic production sites and laboratories

We are moving forward with efforts to improve green space quality at business sites with the aim of maintaining flora and fauna habitats, building ecosystem networks that connect regions and business sites, and invigorate regional partnerships. Under the environmental medium-term plan (2014-2016), we aimed to improve our score on the JBIB Land-Use Score Card™ by 10 points compared with fiscal 2013. As a result of holding nature observation tours with a museum and creating grassland biotopes at business sites, we had improved our average score by 13.4 points (compared with fiscal 2013) in fiscal 2016.

Example of activity to improve quality of green spacesCreation of Grassland Biotope at Kyoto Research & Development Laboratories

Starting in fiscal 2015, Kyoto Research & Development Laboratories has reassessed its greenery in relation to Kyoto City’s Biodiversity Plan. We came up with a concept for creating green spaces, and as our first foray based on this concept, we created a biotope that mimics the grasslands of Miyako with ten varieties of plants centered on the wild thoroughwort, which we had cultivated since 2013.
When the thoroughworts bloomed 2016, employees from Kyoto Research & Development Laboratories observed the biotope and surveyed the fauna and flora in their habitat.

WET Evaluation of WastewaterNew WET * assessments of wastewater at two plants

The Sekisui Chemical Group strictly follows wastewater standards regulated by laws and ordinances and has set even tougher standards for the management of wastewater from its production sites. To prevent negative effects on and ensure the safety of the water environment for aquatic life in the places where wastewater flows, the Group has conducted WET assessments of wastewater and surveys of the habitat conditions in the rivers where wastewater is released since fiscal 2013.

In fiscal 2016, WET assessments were conducted at two business sites, one of which was shown to be impacting the growth of algae, so an investigation of the causes was undertaken. A business site that had previously impacted algae growth was also reevaluated, and it was confirmed that water quality had improved to levels where no impact could be detected.

Over the four years of these surveys, 96% of the water emitted into public water areas by the Sekisui Chemical Group has been checked.
