CSR in the Mitsui Chemicals Group

  • Japanese

The Mitsui Chemicals Group engages in CSR activities based on the concept of realizing its corporate mission through its main businesses. We are undertaking a diverse array of activities to be a company that is trusted and highly valued by all stakeholders and that employees can be proud of.

Creating a Better Future with Blue Value™

What contribution can the chemicals industry make to create a sustainable society? The Mitsui Chemicals Group believes the answer lies in sharing value with its customers. With this in mind, we developed Blue Value™ in 2015.

Including the Group’s materials and products, chemical products pass through a variety of life cycles, from manufacturing and processing to ultimate disposal after actual use. At each life cycle stage we have considered if links can be made to the further environmental orientation of products by visualizing what kinds of environmental loading reductions can be made and sharing them with a wide array of stakeholders. We established the mitsui Sustainability Index (m-SI) in 2013 as a measure for assessing environmental impact based on LCA. Through m-SI, we are able to assess the contribution made to reduce the various types of environmental loading within our product value chains.

Having undertaken checks for the transparency and objectivity of the evaluation process and reviewed the degree to which the checks are understood, the Group’s products evaluated utilizing m-SI on the basis of the three environmental contribution elements—CO2 reduction (A Low-Carbon Society), resource protection (A Recycling-based Society), and co-existence with nature (A Symbiotic Society)—are ultimately certified as exhibiting Blue Value™ as complete products and technologies.

Products that help to “realize a cohesive society that is in harmony with the environment,” as promoted in the 2014 Mid-Term Business Plan, have undergone wide-ranging Blue Value™ evaluations and reviews.

As examples of products that have newly received Blue Value™ certification, there are ARLEN™ and AURUM™, which as materials to replace metals in automotive applications display exceptional high-temperature rigidity and dimensional stability and are contributing to improved fuel efficiency. Also, in food packaging applications, there is ECONEIGE™, which contributes to reducing the amount used by using air to facilitate its shielding properties and to the saving of resources by negating the need for printing.

Having identified “low environmental-footprint products and services” as a key issue (Materiality), the Mitsui Chemicals Group is helping to resolve social issues by reducing environmental load throughout the value chain by expanding the deployment of Blue Value™ products and technologies.

LCA(Life Cycle Assessment):
A method of quantitatively assessing the environmental impact of products at all stages, including development, manufacturing, transport, use, and disposal.

Trends in Blue Value™ Product Sales

In fiscal 2015, Blue Value™ sales amounted to approximately \226 billion, a decline compared with fiscal 2014 caused by a downturn in product sales amid falling naphtha and other raw materials prices. However, the ratio of Blue Value™ sales accounted for in Group sales rose from 15% to 17%.
