Hitachi High-Tech GLOBAL

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.

Independent Assurance

In order to enhance the credibility of this report, FY2019 figures marked with image:check mark icon have received independent assurance from SOCOTEC Certification Japan Co., Ltd. in accordance with the International Standard on Assurance Engagements (ISAE) 3000 and ISO14064-3.

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.

    Promoting the Recycling of Used Packaging Materials

    Polyethylene garbage bags

    As part of our efforts to achieve a recycling-based society, our Naka Division is actively engaged in the recycling of waste within Japan. Vinyl used in the packaging of components delivered to us is used to manufacture polyethylene garbage bags and plastic folders made entirely from this recycled material, which are then used by the Naka Division. Seeing vinyl materials separated from other waste in the workplace come back to be used again in a different form makes the concept of recycling more tangible for staff, thereby helping to increase the environmental awareness of each and every employee. Going forward, we will continue to strive to reduce waste by expanding the scope of items subject to recycling and promoting the reuse and recycling of materials used to package components.

    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.
