Installation of Solar Power Generating Systems
The Kyocera Group has introduced solar power generating systems at facilities at home and abroad, such as the Kyocera Headquarters Building and Kyocera International Inc. in North America.

In FY2017, solar power generating systems were additionally installed at three sites: Hokkaido Kitami Plant, Kyoto Ayabe Plant, and Kagoshima Sendai Plant. The cumulative power generating capacity in and out of Japan totaled over 12MW. We continue to introduce solar power generating systems at more sites of the Kyocera Group to promote reduction in CO2 emission.

Cultivating “Green Curtains”
The Kyocera Group started the “Green Curtain” campaign in 2007, which is to cultivate climbing plants such as goya or morning glory around, over, or on parts of windows and external walls of buildings to block strong summer sunlight and thus reduce air-conditioning loads as part of our summer energy-saving activities.

In FY2017, Green Curtains were cultivated at 27 plants and offices in Japan. The Green Curtains cultivated total to about 710m in length and about 2,900m2 in area. This is equal to reduction of about 10,000 kg-CO2* in a year. Since Green Curtains are an ecological activity that we can conduct at hand, we distribute seedlings to local residents and employees to help spread the activity. Harvested goya are provided to our company cafeteria or distributed at summer festivals held by Kyocera.

* Roughly calculated as CO2 absorption (3.5 kg-CO2/m2/year) x Green Curtain cover area (m2) = annual CO2 absorption (kg-CO2/year)

Energy Consumption Reduction by Using Waste Heat of Sintering Furnaces

The Kagoshima Sendai Plant newly introduced boilers that produce steam using waste heat. Introduction of these boilers allowed us to effectively apply waste heat to air-conditioning and production processing and reduce gas consumption.


Annual CO2 emission reduction: 407 ton-CO2

Energy Consumption Reduction by Introduction of Inverters for Vacuum Pumps

The Shiga Yohkaichi Plant introduced inverters for the vacuum pumps in casting furnaces. Introduction of inverters allowed us to operate vacuum pumps at frequencies that match the load of each process and ultimately reduce power consumption.


Annual CO2 emission reduction: 38 ton-CO2

 Effective use of Water Resources
Water Consumption Reduction by Introduction of Wastewater Recycling Equipment
Dongguan Shilong Kyocera Co., Ltd., China, introduced wastewater recycling equipment. The new equipment purifies treated wastewater from production processes to reuse the water in the production process and utility equipment, thereby reducing water consumption.

Annual water consumption reduction: 7,200m3

 Actions for Reduction and Recycling of Wastes
Industrial Waste Reduction by Improvement of Wastewater Treatment Sludge Dewatering Machine
The Shiga Yohkaichi Plant improved filters used in dewatering machines to further reduce the amount of sludge generated from the wastewater treatment system. Optimal selection of filters to match the nature of sludge can improve the dewatering capability to reduce the industrial waste emissions.

Annual waste emission reduction: 120 ton
