Mitsui Chemicals

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 innovation and the creation of materials, 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 is undertaking a variety of measures including tree-planting and cleanup initiatives in a bid to help create an environment that allows 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 commit to take the initiative in our business activities and act in accordance with the declaration and accompanying action policy.

  4. Promote corporate management for sustainable resource use
  5. Create an industry, lifestyle and culture that will learn from biodiversity

Honshu Chemical Industry Co., Ltd.
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 30, 2016, 30 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.

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.

Rare wildlife found in survey (example)

Plants Serissa japonica, tree of a thousand stars
Selaginella moellendorffii
Amphibians Japanese brown frog
Insects Cydnidae, Parastrachia japonensis

Conservation Activities of Our Affiliates in China

On March 2, 2017, Mitsui Chemicals affiliated company Tianjin Cosmo Polyurethane Co., Ltd.’ Suzhou Plant participated in the “4th Protect Mother Lake” (fry releases in Taihu Lake and tree planting on Taiyang Mountain) sponsored by the Suzhou New District’s Environmental Protection Agency Protection Association. Around 250 employees of member companies located in the Suzhou New District took part in this event with the aim of helping to preserve the region’s environment.
Participating since 2016, Tianjin Cosmo Polyurethane assisted with fry releases at Taihu Lake (referred to as “Mother Lake”) along with tree-planting and clean-up activities in Suzhou New District Forest Park this time around.

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 15th time for the activities to be held was on November 16, 2016, 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.
