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 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.

Performance Data

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

• * Reporting boundary: Hitachi High-Technologies (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 FY 2005 {(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}

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

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

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)

• *1 Due to an expansion of the boundary
• *2 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. 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.

Changes in Water Consumption (Outside Japan)

• * Reporting boundary: Overseas subsidiaries (The FY2018 figure includes Hitachi High-Tech Analytical Science and excludes Hitachi High-Technologies Ireland and H.H.T.A. Semiconductor Equipment Israel)
• * From FY2017, water consumption at sales sites where water consumption cannot be ascertained is being estimated from numbers of employees and water consumption at sales sites where water consumption has been ascertained.
