Environmental Initiatives within the Supply Chain

Hitachi Chemical Group’s core segments—Functional Materials, Energy Storage and System Devices, and Automotive Products—are playing a major role in making our customers’ finished products smaller and lighter, and in providing efficient energy use as per their needs. As a result, the Group is contributing to reducing environmental impact throughout the supply chain. Following the rise of overseas sales as a component of overall revenue, we are also helping to reduce the environmental impact of transportation that has emerged in association with the increased local manufacturing.

Curbing Product-derived Environmental Impact

Hitachi Chemical Group is participating in activities that help our customers curb product-derived environmental impact by promoting Sustainable Engineering that capitalizes on our strengths as a manufacturer of high-performance materials and energy storage devices. In our Medium-term Management Plan starting in fiscal 2016, we have set a goal for the reduction of resource usage in a subsection of products and are promoting various activities to achieve this goal. We will continue to make further improvements to our target products and contribute to the reduction of product-derived environmental impact.

Scope 3 Status

The Hitachi Chemical Group also calculates Greenhouse Gas emissions throughout its entire value chain. In fiscal 2013, we started calculating emissions in 12 subject categories out of 15 total categories based on the Ministry of the Environment’s Basic Guidelines for the Calculation of Greenhouse Gas Emissions Volume throughout the Supply Chain Ver. 2.1. In regard to downstream processes, still in the middle of the way, though, we calculated the Greenhouse Gas emissions volume of our main products through Life-Cycle Analysis, LCA, and are planning to make further calculations for assumption based on these results. We implemented LCA for 12 products in fiscal 2017 and plan to implement LCA for 18 major products by the end of fiscal 2018.

Going forward, by improving the accuracy and expanding the scope of Scope 3 calculation, we will utilize the calculations to reduce Greenhouse Gas emissions volume throughout the entire value chain.

Product Recycling

Although some products made out of chemical materials are extremely difficult to recycle, Hitachi Chemical works to promote activities that maximize efficient resource utilization to the fullest extent possible. While such composite materials as wiring boards and carbon fiber-reinforced plastic were very difficult to collect and separate into component materials for recycling, we have established collection and separation technology based on a method for depolymerizing unsaturated polyester under ordinary pressure that allows us to separate composite material wastes into resins, fibers, metals and rare metals and to collect them to reuse as recycled materials. We are currently working to develop a business that collects waste materials from customers and sell them as recycled materials. Additionally, our energy storage devices and systems business actively cooperates with organizations such as the Battery Association of Japan to establish a framework for recycling automotive storage batteries. We also have acquired regional certifications for collecting industrial batteries to push further ahead with efficient and appropriate recycling of used batteries.

Environmental Impact of Transport

In the Hitachi Chemical Group, only the Company falls into the category of designated shippers under the Japanese Energy Saving Law. We are also working to reduce the environmental impact of transport at our other major production sites in Japan, including at other Group companies in Japan.

In fiscal 2017, we have a 1% increase in transport-associated CO2 emissions over the previous year; however, we also have a 4% improvement in CO2 emissions per production unit by pursuing greater transport efficiencies and making modal shifts. As we have been increasing local production following the increase in the share of overseas sales within the Hitachi Chemical Group, we are seeing improvement in reductions in the environmental impact of air and marine transport associated with exports from Japan.
