Environmental Activities and Results
We are working hard to conserve the environment, including reducing greenhouse gas emissions and making effective use of resources, in order to coexist harmoniously with society, our global community and nature ("Living Together").

Energy Conservation Efforts
In June 2019, we installed 2,814 solar panels on the roof of the plant No.5 with the aim of reducing CO2 emissions to prevent global warming. This solar power generation system generates enough electricity to power about 184 ordinary households and contributes to the reduction of approximately 412 tons of CO2 per year. We also successfully reduced the exhaust fan power consumption by 98,496 kWh per year and cut CO2 emissions by about 42 tons annually in Plant No. 3 (toner plant) by installing the air supply and exhaust fan inverter* and decreasing air flow while maintaining the indoor airborne dust concentration below the standard value.
* The device controlling the frequency of power supplied to an AC motor and, as a result, the motor's rotation speed.
● Historical Power Consumption Data
Efforts to Reduce Industrial Waste
We set a reduction target every year to minimize the amount of industrial waste we generate. Since FY 2013, we have been recycling waste toner (not fit for commercialization) generated during production and have increased the recycling rate to over 80%. We also recycle more than 80% of waste plastics as the plastics raw material by carefully separating them from other waste.
● Historical Industrial Waste Generation Data
Efforts to Reduce Water Use
We acquire the pure water needed for toner production by treating city water and well water with a pure water system. Since the system only purifies 60% of the water so we used to drain the remaining 40% as wastewater. Now after installing a wastewater reuse system, we have been able to save 1,000 m3 of water per month.
● Historical Water Use Data

Reduce plastic used for food and drink |
Participation in Biotope Restoration Activities
We have been participating in biotope restoration activities organized by Sugashi Uda Sataoki Kankyo Hozenkai, a local environmental organization, since 2020. Activities in fiscal 2021 included cutting the grass around the biotope, transplanting rare plants, and building a wooden path.
Signing an Agreement to Protect and Restore Rural Landscape with a Local Environmental Organization
As part of our environmental efforts, we have been participating in biotope restoration activities led by Sugashi Uda Sataoki Kankyo Hozenkai, a local environmental organization, since 2020. The biotope restoration activities have been designated by Mie Prefecture as a "Mie Hometown Support Company Promotion Project," designed to revitalize farming and fishing villages. Kyocera Document Solutions signed an agreement with the environmental organization which was witnessed by the governor of Mie Prefecture and the mayor of Tamaki Town. When we started participating in the project, rice paddies located at the bottom of a valley had been abandoned for more than 10 years due to the difficulty of introducing agricultural machinery, which made rice farming labor intensive. They had turned to wetlands where Japanese alder and sasa palmata thrived due to constant inundation from an underground water source. Today this wetland area is being steadily transformed into a biotope through weeding, thinning, planting, maintenance of waterways, etc. In addition to this work, the biological survey started in 2018 confirmed that many rare plants and animals* on the Red List of Threatened Species live in the area. Since the biotope is expected to be used for research on rare plants and animals and as a place for environmental learning, we are constructing a timber walkway here to provide children with a safe and environmentally friendly learning environment while working on development of the biotope.
* Plant species listed as Vulnerable : Scirpus mitsukurianus Makino and Pogostemon yatabeanus
Animal species listed as Vulnerable : Mortonagrion selenion, Lefua echigonia, and Cybister brevis
Plant species listed as Near Threatened : Hosta longissima Honda ex F.Maek
Animal species listed as Near Threatened: Neozephyrus japonicus and Hydaticus bowringi Clark
