Conserving the Natural Environment ~ Biodiversity ~

We Strive to Conserve Biodiversity which includes Natural Environment.

Management Approach

Basic ConceptReducing the Impact of Business Activities on Biodiversity

While the business activities of the Sekisui Chemical Group receive blessings of nature coming from biodiversity, they also negatively impact the ecosystem. In April 2008, the Sekisui Chemical Group incorporated biodiversity related items into its Environmental Management Policy. Following this, the group has been making efforts than ever before, to reduce the environmental impact of greenhouse gas emissions and hazardous chemicals, etc., and to prevent pollution by promoting the effective use of limited resources and energy. In 2011, the Group also established a set of guidelines on biodiversity, and strives to conserve biodiversity including natural environment, through both environmentally conscious business activities and actions to preserve the environment undertaken around the world.

Long-term Environmental Management VisionToward the Realization of a Planet Where Biodiversity Is Preserved

In order to contribute to the realization of a planet where biodiversity is preserved, the Sekisui Chemical Group aims to return more natural capital to the planet than it uses by 2030, through three initiatives: expand and create Environment-Contributing Products, reduce environmental impact, and conserve the natural environment.

Biodiversity AssessmentAssessing the Environmental Impact and Confirming the Effect on Biodiversity

At the Sekisui Chemical Group, the Environmental Subcommittee of the Group, which is positioned under the CSR Committee, headed by the President, meets twice a year to deliberate on biodiversity with regard to the Group’s business activities, and to assess their impact. As a specific method to assess impact on the environment, the Company uses the JBIB Land Use Score Card®*1, a tool for evaluating the level of effort to preserve biodiversity with respect to land use, as well as WET*2, which evaluates the impact on living organisms exerted by waste water.

With the Sekisui Chemical’s large-scale land developments including the construction of one of its plants, or when new land is acquired as a result of an M&A or other activity, the Company conducts an environmental impact assessment with regard to the potential effect that the Company’s business could have, including on the air, bodies of water, or soil. Within this environmental impact assessment, we also confirm the impact on biodiversity.

Major Initiatives

SEKISUI Environment WeekHeld to Help Develop Human Resources with Excellent Environmental Activity Promotional Skills

For a fifth time, in fiscal 2017, a total of 25,277 employees participated in activities.

The activities were creatively devised to match each business site and included beautification around the areas, tree planting, energy-conservation in the offices and much more.

Procurement of Sustainable Raw MaterialsThe Usage of Sustainable Timber and the Assurance of Traceability

At the Sekisui Chemical Group, in order to contribute to the elimination of deforestation as well as the sustainable use of timber resources, every effort is made to ensure that the timber used in products is logged in accordance with statutory and regulatory requirements, such as FSC certified wood. In addition, investigations on commercial distribution with regard to the logging area, tree species and quantity of timber materials are implemented, in order to ensure traceability. For recycled materials, we use timber and wood based materials that are already used in markets, as well as unused thinnings and branches.

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 (2017-2019), we aimed to improve our score on the JBIB Land Use Score Card® by 5 points compared with fiscal 2016. As a result of planting local seeds and saplings, activities to get rid of invasive alien plants, and other activities, we had improved our average score by 2.6 points (compared with fiscal 2016) in fiscal 2017.

Initiatives to Conserve Ecosystems in Protected AreasPark-like Production Plant in the Middle of a Forest Rich with Nature

Sekisui Medical Co., Ltd. Iwate Plant is placed adjacent to the Towada-Hachimantai National Park, and its park-like grounds are rich in greenery and natural beauty, of which 95% of the area is covered by green. There, high-quality pharmaceutical products which are distributed throughout the world are manufactured, in a safe and efficient manner. Through its environmentally friendly wastewater treatment system and reduction of CO2, the plant aims to exist in harmony with its surrounding precious natural environment. As a result of investigation for birds, plants and animals that gather at surrounding areas including streams and springs, 673 species were found. Of these, 14 species are recognized as ecologically valuable. As a recognition for above activities, the Iwate Plant has acquired 4 Stars (highest rank) for the “Iwate-friendly business place certification system*,” certified by Iwate Prefecture. Through manufacturing, the plant will continue to contribute to people’s healthy and fulfilling lives, and the conservation of ecosystems.

An Example of Our Initiatives to Improve Green Space QualityCreating a Biotope in Harmony with the Regional Ecosystems

In May, 2017, Kyushu Sekisui Heim Industry Co., Ltd. newly created a biotope (named “Heim Forest”) which exists in harmony with the regional ecosystems.
The company planted 27 kinds of seeds and sapling native to Tosu, the area the Company is located in, such as Camellia japonica and Cornus kousa, which all grow very well in the region, and created a biodiversity-sensitive, green tract of land inviting all kinds of living things of the surrounding area to live there. During the SEKISUI Environment Week held in fiscal 2017, as a part of the initiative, company employees attached tree name tags to trees in the area. Heim Forest is used by employees on weekdays as a space for relaxation and also by visitors to the factory during factory tours as a resting area. In the future, the Company intends to improve the quality of this green space further and perhaps even make it open to residents of Tosu and other neighboring areas.

  • Attaching tree name tags during
    the SEKISUI Environment Week

  • Serving as a space for relaxation for employees on weekdays

In 2000, Kyushu Sekisui Industry Co., Ltd. created a biotope of around 6300m2 inside its premise named “Country Woods.” Drainage from the factory (cooling water from machinery) is reused for the pond inside the biotope. The trees that were small when the creation of biotope began have now grown, and some are over 15m high. Also, many different species can be found inside the biotope. Birds like the kingfisher make visits, apatura metis fly around the weeping willow, and Japanese moles live underground. Biotope also became home for some ecologically valuable species. Salvia plebeia (Near Threatened), whose light purple flowers bloom in April and May, grows by the waterside, and Abbottina rivularis (Endangered) lives inside the pond. The biotope is open to the public, and “education for nature conservation,” “natural environment field trips,” and “biological research” are conducted, while existing as a place for relaxation for the local community.

WET Evaluation of WastewaterInvestigation of Causes at Business Sites Where Impact Had Been Confirmed by Previous Surveys

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.

Looking at past surveys, 96% of the water emitted into public water areas by the Sekisui Chemical Group production sites has been checked. In fiscal 2017, the Company conducted investigations into causes at business sites where past surveys have revealed an impact on living organisms.
