Recycling of Resources

Basic Approach

Hitachi High-Tech Group is aspiring to create a recycling-oriented society, as part of our efforts for a 50% improvement in efficiency of resource use compared to the base year, by FY2050 and our final goal of zero emissions (less than 0.5% of volume of waste generated) through reduction based on environmentally conscious design for in-house products, recycling with carefully sorted collection, reuse of unused goods, and use of recycled water.

Initiatives

Reduction in the Volume of Waste Generated / Higher Rate of Reuse of Resources

At Hitachi High-Tech Group companies, efforts are made to reduce the volume of waste that is generated in their business activities as well as to promote recycling of resources by maximizing recycling of generated waste.
In fiscal 2019, activities seeking to improve the volume of waste generated per unit by 13% (base year: fiscal 2010) realized an improvement of 23.6%, meeting the target. From FY2019, the base fiscal year was changed from 2005 to 2010 in accordance with the Hitachi Environmental Innovation 2050 program.

Performance Data

Changes in Volume of Waste Generated in Japan –Improvement Rate per Unit

• * Reporting boundary: Hitachi High-Tech (excluding branches), group manufacturing companies (excluding Hitachi High-Tech Kyushu and Tokyo Solution Laboratory), and service companies in Japan
• * Energy usage improvement rate per unit: The rate of improvement over the base {(1 - base units of the relevant site for the relevant fiscal year/base units of the relevant site for the base year) x environmental impact at the relevant site for the base year calculated by group companies in Japan}
• * Figures up to FY2018 are on a 2005 fiscal year basis, and from FY2019 on a 2010 fiscal year basis.

Changes in Volume of Waste Generated and Final Disposal Ratio in Japan

• * Reporting boundary: Manufacturing sites of Hitachi High-Tech and group manufacturing companies in Japan
• * Figures include waste, including valuable resources, generated from manufacturing activities

Changes in Volume of Waste Recycled and Rate of Reuse of Resources in Japan

• * Reporting boundary: Manufacturing sites of Hitachi High-Tech and group manufacturing companies in Japan

Changes in Amount of Waste Generated (Outside Japan)

As to the volume of waste generated at overseas subsidiaries, since FY2017 we have only been tracking hazardous wastes that are regulated in the country concerned. Going forward, we will consider activities to reduce those wastes.

* Reporting boundary: Overseas subsidiaries (Figures only include overseas manufacturing companies from FY2017. Hitachi High-Tech Analytical Science was newly included in the boundary from FY2018)

• * Figures from FY 2017 include hazardous waste generated from manufacturing sites only. Figures up to FY2016 include waste generated from manufacturing and non-manufacturing sites

Initiatives

Effective Utilization of Water Resources

Hitachi High-Tech Group is working to utilize water effectively. These measures include reducing the volume of water used through initiatives including productivity improvements and upgrading to water-conserving equipment. We pursued activities in FY2019 with a target for reduction in water use per unit of 43% (base fiscal year 2010) and achieved 49.2%. Hitachi High-Tech also performs global water stress assessments every year, as well as water risk assessments at all sites in Japan. None of our business sites indicate high stress or high risk. Going forward, however, we will continue working to avoid risks at sites where risk reduction is possible. From FY2019, the base fiscal year was changed from 2005 to 2010 in accordance with the Hitachi Environmental Innovation 2050 program.

Performance Data

Changes in Volume of Water Consumption in Japan – Improvement Rate per Unit

• * Reporting boundary: Hitachi High-Tech (excluding branches), group manufacturing companies (excluding Hitachi High-Tech Kyushu and Tokyo Solution Laboratory), and service companies in Japan
• * Energy usage improvement rate per unit: The rate of improvement over the base {(1 - base units of the relevant site for the relevant fiscal year/base units of the relevant site for the base year) x environmental impact at the relevant site for the base year calculated by group companies in Japan}
• * Figures up to FY2018 are on a 2005 fiscal year basis, and from FY2019 on a 2010 fiscal year basis.

Changes in Water Withdrawals in Japan

• * Reporting boundary：Manufacturing sites of Hitachi High-Tech and group manufacturing companies in Japan(up to FY2018) Includes sales-related and service-related companies in Japan since FY2019

Changes in Water Withdrawals (Outside Japan)

• * Reporting boundary: Overseas subsidiaries (The FY2018 figure includes Hitachi High-Tech Analytical Science and excludes Hitachi High-Tech Ireland and Hitachi High-Tech Israel)
• * From FY2017, water withdrawals at sales sites where water withdrawals cannot be ascertained is being estimated from numbers of employees and water consumption at sales sites where water withdrawals has been ascertained.
• * The 75 sites in FY2018 increased to 84 sites for calculation in FY2019. Figures increased in some of the sites due to errors caused by water leaks and errors in calculation method.

CDP^*Evaluation

At Hitachi High-Tech Group, we have been responding to the CDP Water Security Questionnaire. In FY2019, we received a score of "Management level: B", which indicates an awareness of the environmental burdens and risks associated with our business and of their effects. In addition to continuing water risk management (tracking) in the Hitachi High-Tech Group, we will draw up measures and responses to address risks and will make every effort to enhance corporate value.
