Environmental Protection


The Mitsui Chemicals Group strives to protect biodiversity and promote business activities that encourage sustainable use based on its corporate mission to “contribute broadly to society by providing high-quality products and services to customers through innovations and the creation of materials and products while keeping in harmony with the global environment.”

Basic Approach to the Preservation of Biodiversity

  1. We conduct our business activities in gratitude for the blessings of nature and biodiversity and recognize that environmental preservation is a globally important issue.
  2. We contribute broadly to society by encouraging the preservation of biodiversity through the supply of environmentally friendly materials, products, and services.
  3. We will comply with international biodiversity agreements.
  4. We strive to preserve biodiversity by cooperating with relevant parties in Japan and abroad and within and outside the company and taking into account its effect in the supply chain.
  5. To protect biodiversity, we will promote employee social contribution activities that have our stakeholders trust.

Although we make every effort to incorporate biodiversity into all of our day-to-day business activities here at the Mitsui Chemicals Group, we are particularly increasing our focus on areas such as chemical safety and management, based on the fact that environmental initiatives are inextricably linked to biodiversity. Moreover, the Group as a whole, including its subsidiaries and affiliates, is undertaking a variety of measures including cleanup initiatives in a bid to help create an environment that allows plant life and living organisms to thrive.
On January 22, 2010, the Group signed up to the Japan Business Federation's (Keidanren) Declaration of Biodiversity as a Promotion Partner. This means that the Group supports the seven principles set out in the declaration and that we intend to take the initiative in our business activities and act in accordance with the declaration and accompanying action policy.

  5. Create an industry, lifestyle and culture that will learn from biodiversity

Participating in Wakayama Prefecture's Company forest scheme

As part of its environmental activities, our affiliate Honshu Chemical Industry Co., Ltd. signed a Forest Conservation and Management Agreement with Wakayama Prefecture and Hidakagawa Town on September 7, 2010, with the aim of participating in Wakayama Prefecture's Company Forest conservation scheme.
As part of the Company Forest scheme, Wakayama Prefecture, forestry cooperatives, and companies work in partnership to effectively harness the prefecture's rich natural environment and get local people involved in environmental preservation.

In November 2010, Honshu Chemical Industry held a tree-planting event. As part of this event, employees and members of their families planted approximately 1,500 trees on a 1.32-hectare area of forestland in Hidakagawa Town (Hidaka-gun, Wakayama Prefecture). The forest was also given the official title "Hidakagawa Honshu Chemical Industry Forest."

On July 25, 2015, 32 people from the company participated in the cutting of weeds at the Hidakagawa Honshu Chemical Industry Forest under the guidance of the Nakatsu Forestry Cooperative, which has been entrusted with the forest’s local management.
Participants worked while struggling with difficult footing and the waist-high undergrowth, but were able to cut the undergrowth in about one hour.

Wildlife survey on rice fields

Pests that feed on rice plants are the greatest threat to rice production. With the idea of raising awareness of the numerous living things other than pests that inhabit rice fields, the Mitsui Chemicals Group affiliate company, Mitsui Chemicals Agro, Inc. (MCAG), has been conducting a “Wildlife Survey on Rice Fields” using MCAG products since 2012.
Involved in the manufacture and sales of agrochemicals and fertilizers, MCAG conducts the “Wildlife Survey on Rice Fields” annually with the full support of customers, confirming that a wide variety of wildlife inhabit rice fields. MCAG surveys the effects of agrochemical use on wildlife in rice paddies, which leads to the improvement and development of products. Further, through the release of experts’ written opinions that summarize the results of these wildlife surveys, we certify that rice was grown in rice paddies inhabited by a wide variety of wildlife, which contributes to adding value to local rice.

MT AquaPolymer, Inc. High-Concentration Liquid Polymer Flocculants

The Mitsui Chemicals Group affiliate company MT AquaPolymer manufactures and sells high-quality, high-concentration liquid polymer flocculants realized by high polymer technologies.

A source of pride for the company over many years, its ACCOFLOC® and ARONFLOC® products are agents that by flocculation action cause clumping and mass precipitation and are thus highly effective in separating water from the sludge generated in the purification process of domestic wastewater. Hygienically reducing the amount of wastewater treatment that can affect disposal, these products are extensively utilized not only at wastewater treatment plants but also in the factory effluent treatment field, including paper and food processing.

MT AquaPolymer is working to conserve natural resources and biodiversity as well as carry out improvements through the manufacture and sale of environment-friendly products, such as high-concentration liquid polymer flocculants.

Preservation Activities at Omuta Works

At the Omuta Works (Fukuoka Prefecture), Mitsui Chemicals has a protected forest that spans approximately 5.4 hectares and engages in ongoing activities to preserve this area. In 2009, we cooperated on a survey of the natural environment in the forest around our property (the southern side of Mt. Takatori) at the request of Omuta City, which considers the preservation of the natural environment an important issue. The survey conducted by Omuta City Natural Environment Survey Association examined rare plants and species of living organisms in areas managed by Omuta Works, and presented its findings in the Omuta City Natural Environment Survey Results Report.

Conservation Activities at Shimonoseki Mitsui Chemicals

The Mitsui Chemicals Group affiliate Shimonoseki Mitsui Chemicals, Inc. has been participating in the “Forestation Meetup Event to Protect the Waters of the Koya River” since 2001.
As the purpose of the event is to maintain and promote the water conservation functions served by forests, the local government and Shimonoseki Mitsui Chemicals have continued to conduct the activities centered on companies that utilize water from the Koya River.

The 14th time for the activities to be held was on November 13, 2015, in the mountain forest on the outskirts of Tawarayama-Tsunburi River Green Erosion Control Park (in the town of Tawarayamayu, Nagato City, Yamaguchi Prefecture). The planting of zelkova seedlings, the cutting back of weeds to protect the seedlings, and the pruning of cherry and zelkova trees to encourage them to grow tall and sturdy contributed to maintaining the forest.

Conservation Activities at Saxin Corporation

Each year, the Mitsui Chemicals Group affiliate Saxin Corporation participates in activities with the purpose of conserving the local environment. There were two activities in fiscal 2015. On April 8, the company took part in river cleanup activities organized by an agricultural cooperative, activities that involved removing the algae and sludge that accumulate in rivers. Then, to provide assistance ahead of cleanup activities undertaken by citizens living around Lake Biwa in Shiga Prefecture, which were held by the local government on July 4, the company cut back weeds and grass and cleaned up a stretch of the Koyama River on the preceding day, July 3.
