In FY2022, continual improvements in manufacturing, energy-saving measures, updates company cars to environmentally conscious cars and the use of renewable energy were considered at its sites around the world. At our Hachioji Facility, boiler efficiency was improved by installing thermal jackets on the boiler piping to reduce thermal energy loss and improve boiler efficiency, and Aomori Olympus has worked to reduce energy waste by replacing compressors with high-efficiency equipment and installing air flow meters to identify air leaks and implement countermeasures. KeyMed (Medical & Industrial Equipment) Ltd. in Europe switched some of its company vehicles used for sales activities to electric vehicles. At Olympus Surgical Technologies America (Gyrus ACMI, Inc.), starting in 2021, 30% of the electricity used at the Redmond site, 100% at the Bartlett site, and 20% at the newly opened Westborough site switched to renewable energy sources. In April 2022, we converted 100% of the electricity used at our major development and manufacturing sites in Japan (10 sites) to electricity derived from renewable energy sources.
For wider use of renewable energy, studies are focusing on dissemination, economic feasibility and other factors in each country.
The renewable energy use rate vis-á-vis the total electric power consumption has risen to 18.9% (compared to 12.2% in the previous year).

The Olympus Group uses water mainly in production processes, such as for cleaning components and cooling, as well as in its dining halls. We implement thorough wastewater control by adopting stricter standards than the legal requirements in each region, and we continue to reduce water consumption and wastewater emissions by setting targets in those sites that have high water consumption. We are also acting to conserve water resources under collaborations with local communities at each site.
In FY2022, we reassessed the water risks at each of our sites using water risk assessment tools (e.g. Water Risk Filter, Aqueduct), hazard maps, and their water usage. In Japan, our Nagano Facility makes effective use of waste water from the purification of deionized water by collecting it for secondary use in the manufacturing process, the Shirakawa Facility has reduced water consumption by shortening the time required for washing with hot running water after surface treatment in the manufacturing process; and Aizu Olympus has reduced water consumption in the painting process by changing the cleaning process from small lot processing to batch processing and introducing water-saving shower washing machines in a separate process. KeyMed (Medical & Industrial Equipment) Ltd. in Europe purifies and reuses water from the painting process. At our Nagano Facility, with the consent of the local fishery cooperative, wastewater is continuously monitored, and regular inspections of water treatment facilities are carried out to ensure strict water management so as to minimize the impact on the ecosystem. The Nagano Facility also helps maintain the local forest that serves as a water source for the area under a Forest Fostering Agreement concluded with the Monzen Forest Association and Tatsuno Town in Nagano Prefecture. Olympus Surgical Technologies America (formerly Gyrus ACMI, Inc.) in the U.S. received a Gold Award*1 in recognition of long-time efforts to maintain compliance with the industrial wastewater discharge permit requirements set by King County, Washington.
