Hitachi High-Technologies 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, FY2018 figures marked with check mark icon have received independent assurance from KPMG AZSA Sustainability Co., Ltd. in accordance with the International Standard on Assurance Engagements (ISAE) 3000 and ISAE 3410.

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 2018, activities seeking to improve the volume of waste generated per unit by 39.4% (base year: fiscal 2005) realized an improvement of 43.7%, meeting the target.

Amount of Waste Generated (Outside Japan)check mark icon

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.

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. In FY 2018, the target was 45.1% improvement in water use per unit (base year: FY 2005), but the activities undertaken resulted in 40.2% improvement. The target was not met due to water leaks accompanying equipment degradation. Also, water stress and water risk assessments are conducted each year. No business sites were found to have high stress or risk. Going forward, we will strive to avoid risks by periodically conducting such assessments.
