Biodiversity | Environment | Sustainability | Asahi Kasei



To ensure the sustainable utilization of living resources, the Asahi Kasei Group gives due consideration to reducing the impact of our business activities on biodiversity, and we have established guidelines for the preservation of biodiversity. Based on these guidelines, we have been working to understand the relationship between our business activities and biodiversity since 2010. In order to promote business activity mindful of biodiversity, we are working to raise awareness among personnel by various means including our Responsible Care (RC) education program.

Investigation of impact on biodiversity by procurement

Regarding the impact of our business activities on biodiversity when there is a newly used raw material or a change in use of raw materials, we use a survey sheet on the relationship between business operations and biodiversity to examine the country of origin of raw materials, processers and manufacturers, and primary vendors (trading companies, etc.), in order to confirm the absence of any problem.

Group-wide activities for biodiversity

  • Asahi Kasei Group, Town Woods Program

What is the "Town Woods" Program?

We aim to increase value from the perspective of biodiversity while enhancing green spaces at Asahi Kasei Group operating sites. We will use Town Woods Pots as a tool to heighten understanding and awareness of the value of biodiversity among personnel.

What are Town Woods Pots?

This new way of landscaping by Asahi Kasei Homes combines four layers of vegetation of varying heights: Tall, medium, short, and groundcover. While compact enough to integrate with urban residential areas, they increase the space for other plants and wildlife in artificial environments that otherwise have little greenery. Our Town Woods Program uses the phytosociological method to classify green spaces at operating sites throughout Japan, selecting the most suitable regional vegetation when creating the Town Woods plantings.

  • Trees draw birds and butterflies / Feel the four seasons with flowers and autumn foliage / Taller tree 1 tree, 2 meters high / Medium tree 1 tree, 1 meter high / Shrubs 2 bushes, 0.5 meter high / Groundcover 8 plants
  • Town Woods Areas / Ezo/Mutsu / Kanto Region: Northern Coast, Inland, Southern Coast / Fossa Magna Region: Inland, Coast / Japan Sea Region: Northeast, Southwest / Mino/Mikawa Region / Atetsu Region / Sohayaki Region: Eastern Setouchi, Western Setouchi, Kii, Shikoku, Northern Kyushu, Southern Kyushu / Blue dots designate company locations

Interviews with local plant growers

We favor local saplings and seedlings for the Town Woods Pots, we have interviewed a grower who provides them for this initiative.

"Growing seeds taken from the wild. This is really interesting."

Takashi Matsui:
Plant advisor, horticulturist

We are a local plant nursery that grows and sells plants for gardening and green spaces. In addition to Japanese cedar, hinoki cypress, and pine trees for forestry, we also grow a variety of trees that can be found growing wild in the region. That includes native species growing locally that we collect seeds from and germinate. We sell the saplings as a "local product."

I became interested in local plants about 25 years ago. At the time, many of the trees on Lake Biwa's Chikubu Island died from contamination by the droppings of great cormorants. In order to regenerate the island's plant life, a project was started to collect seeds locally, grow seedlings, and reforest the original area.

One of the difficulties in dealing with native plants is that some varieties naturally only germinate when birds eat the fruits and expel the seeds along with their droppings. Such plants rarely germinate if someone simply takes the seeds and plants them. So we need to replicate the process that would happen if a bird ate the fruit. We rub it by hand to remove the skin and flesh and leaving scratches on the seeds. This allows them to germinate. The process differs depending on the variety, and through repeated experimentation we have learned to cultivate more than 100 species.

It's generally said that there is little demand for locally produced plants, but recently, I feel that private companies are gradually becoming interested in them in their efforts to conserve biodiversity. I'd like to see more local plants being sought out as society gains a greater understanding of this.

Notable activities in fiscal 2019

Actions in the Moriyama Area
Ex-situ conservation of endangered smallhead stickleback, a freshwater fish

In Moriyama, we draw groundwater for industrial use in cooling equipment. Its quality is strictly monitored, and it is discharged to nearby rivers after use. A portion of the discharged water from our Moriyama Works is also used for agriculture, which has become vital for local farmers as well as wildlife inhabiting the waterfront areas.
Against this backdrop, and since water is intrinsically related to our business operations, we started initiatives to protect biodiversity with a focus on water resources starting in fiscal 2010.
In fiscal 2015, we began ex-situ conservation activities focused on the smallhead stickleback, a freshwater fish which is designated as an endangered species. In fiscal 2019, we held a tour at Lake Biwa Museum in Shiga Prefecture for employees and their families to help conserve smallhead sticklebacks. During the tour, the curator explained the current status of smallhead sticklebacks and the importance, purpose, and results of ex-situ conservation. After that, we visited the Protection and Proliferation Center set up in the same building. We intend to continue our conservation work in collaboration with various organizations.

Actions by Asahi Kasei Juko Co., Ltd.
Project to rediscover living with the woods and water in Higashiomi

The Shiga Plant of Asahi Kasei Juko (AKJ) is located in the Yuya area of Higashiomi City where there had formerly been a diverse lakeside ecosystem of ponds, rice paddies, and woods. There was a culture of life centered around ponds for irrigation and firefighting. By restoring some of the ponds, AKJ is preserving the habitat for local wildlife, conveying the importance of this to community residents through activities like observation tours. We also hold events at the plant, creating a venue that will lead to the protection of forests and crops as local resources.
In fiscal 2019, in cooperation with Higashiomi City and other entities, we held wildlife observation tours lead by specialists during the plant's fall festival. These took place at the Yuya Hebel Biotope that was created on the grounds in 2017 to protect wildlife inhabiting the lakeside ecosystem.
We report on these activities both inside and outside the company through public relations magazines and other outlets. In June 2020, the Shiga Plant received the Director's Award in the Environmental Partnership Division of the Environmental Conservation Excellence Office sponsored by Environmental Conservation Association Of Shiga Prefecture (the award ceremony was postponed to November 2020 due to the spread of COVID-19).

Actions in Fuji Area
"Asahi Woods of Life" project

Asahi Kasei and Asahi Kasei Homes created the Asahi Woods of Life in 2007 as an ecotope on the grounds of our plant in Fuji City to restore the natural environment and village landscape of the Tagonoura area and preserve the local ecosystem. We have been conducting surveys and researching biodiversity there. By developing the Asahi Woods of Life, we nurture local plant and animal life via an ecological network that incorporates forests and the area's green spaces as a whole. We use this to support human development through environmental education and emotional training, applying the insight gained through these activities to business operations.

Principal Activities

  • To monitor and manage the growth of the Asahi Woods of Life, we perform surveys of the afforested area, including a fixed vegetation survey, a survey of each tree, a comprehensive vegetation survey, and a survey of birds and insect fauna. We also conduct a monitored survey of the creation of ecological networks in conjunction with ecosystem surveys of nearby parks, residential areas, and elementary schools.
  • In conjunction with government officials and museum personnel, we hold nature observation tours as part of our environmental education activities in connection with children's environmental clubs and other organizations.
  • We also hold a firefly watching event in early summer to deepen communication with the community.
  • In recognition of these activities, in July 2019, the project was received Stage 3 certification in the Nurturing Category of SEGES (Social and Environmental Green Evaluation System) administered by the Organization for Landscape and Urban Green Infrastructure.

Actions in Nobeoka and the Hyuga Area

Since 2007 we have participated in a reforestation program led by Miyazaki prefecture to create forests in cooperation with companies. We planted more than 44 hectares of broad-leaf trees and other trees native to the area, replacing plantations of cedar and cypress. This included 20 hectares in Hinokagecho, 20 hectares in Takachiho, 1 hectare in Gokase, and 3 hectares in Kitakatacho.

In fiscal 2020, we received an area of about 5 hectares from Hinokagecho. We were preparing for our first tree-planting festival (Hinokage Asahi no Mori III) on Saturday, April 25. It was canceled in accordance with measures to prevent the spread of COVID-19. We are considering holding a tree-planting festival next year while seeing how the situation unfolds.
