Installation of Solar Power Generation Systems |
 |
The Kyocera Group introduced solar power generating systems in various locations in and outside Japan, such as at the global Kyocera Headquarters building in Kyoto and at Kyocera International Inc. — Kyocera's North American holding company.
In FY2011, we introduced solar power generating systems with a total of 836kW at 9 locations in and outside Japan, thus exceeding 2MW in total for all solar power generating systems introduced within Kyocera Group companies in and outside Japan. Carbon dioxide emission reduction due to these installations will be about 968 ton-CO2 annually. Furthermore, Kyocera has installed solar power generating systems at all of its 10 manufacturing plants in Japan. Kyocera will continue to promote CO2 emissions reduction in its business activities by actively introducing solar power at its Group company facilities. |

Solar Cell Production Process |
|
The Shiga Yohkaichi Plant implemented energy saving measures in its solar cell production process, such as a cold and hot water supply with a high efficiency heat source by integrating heat sources between plants, introduction of free cooling and use of waste heat from compressors to preheat water for purification.

Introduction of High-Efficiency Heat Pumps |
|
| The Shiga Gamo Plant and Shiga Yohkaichi Plant replaced absorption chillers, which run on utility gas, and water heaters, which run on heavy oil, with heat pump systems which run on energy efficient electricity. The effects of carbon dioxide emission reduction due to this measure will be about 581 ton-CO2 annually. |

Fuel Conversion |
|
| Dongguan Shilong KYOCERA Co., Ltd. and KYOCERA Document Technology (Dongguan) Co., Ltd. our production sites in China, switched the fuel used for cooking in the cafeteria and water heaters from diesel fuel to natural gas. The effects of carbon dioxide emission reduction from this conversion will be about 403 ton-CO2 annually. |

Power Saving in Powder Conveying Blower |
|
| Introduction of compressor quantity control system |
|
|
|
We developed a compressor quantity control system in-house and introduced it at the Kagoshima Kokubu Plant.
In addition to reducing wasted power at the time of unloading, this system also contributes to reduced set pressure and early detection of malfunction by making it easy to see wattage and pressure.

The KYOCERA Document Solutions Inc. Tamaki Plant replaced the powder conveying turbo blowers in the toner manufacturing line with energy efficient roots blowers. We are also striving to reduce power consumption further by switching the air volume control from control by damper to controlling the number of revolutions by inverter.

Introduction of Multi-Energy Operation System |
|
At the Kagoshima Kokubu Plant, a multi-energy operation system was established with optimum operation designed in combination of an existing absorption type refrigerator with a cogeneration system and a high-efficiency turbo chiller newly introduced. Its operation started in June, 2005.
The "multi-energy operation system" supplies the plant power demands with electricity purchased from electric power companies and electricity generated by a cogeneration system and also supplies HVAC demands for air conditioning with an absorption-type chiller and turbo chiller.
This system allows us to reduce CO2 emission and minimize the energy cost by selecting operational mode-using or stopping co-generation, changing chiller operated and/or adjusting operation temperature of each type of chiller-depend on the operation status of the plant, season, time zone and energy cost required. |

CO2 Emissions Reduction in Distribution |
|
| In FY2011, we implemented measures such as a continuous effort for modal shift and a review to shorten transportation distances. However, as an expansion in orders resulted in increased freight shipping, the CO2 emissions from freight transportation in FY2011 increased from FY2010 by 40.2%. Meanwhile, the CO2 emissions per net sales increased by only 0.9% from FY2010. |
The Kyocera Group is promoting eco-friendly distribution in and outside of Japan. Shanghai KYOCERA Electronics Co., Ltd., a manufacturing plant in China, which previously used air cargo to transport products to Hong Kong, switched the transportation of part of its products from air to truck in January 2009. In October 2010, it further switched to railway, reducing CO2 emissions during transportation.
We will continue to increase the use of transportation methods that cause less of an environmental burden, such as railway, to reduce CO2 emissions arising from transportation of goods. |
|
| * |
Results from October 2010 through March 2011 |
| Note: |
The CO2 emissions reduction effect is calculated using the CO2 emissions per net sales based on the Joint Guideline Ver. 3.0 for Calculating CO2 Emissions in the Logistics Sector, and CO2 emissions arising from the previous transportation method and the transportation method in January 2009 have been calculated using the transportation loads during the 6 months from October 2010 to March 2011. |
|
|
 |
|
Overseas products from the Kagoshima Kokubu Plant and Kagoshima Hayato Plant used to be shipped to Osaka by using trucks. We set up a new route using ferries with even lower environmental impact to reduce CO2 emissions produced during transportation.
Using ferries, we have shortened the shipping time by reviewing the delivery management, changing the shift of packing operation, and making the warehouse operation more efficient. |
|
|
| Reviewing the Transportation Route |
|
|
|
| Products produced at the manufacturing plant for photovoltaic generation modules in China used to be transported to the sales office in Suzuka City from Osaka Port and Kobe Port via the Mie Ise Plant. We reviewed transportation route to transport such products to the sales office via Yokkaichi Port, thereby reducing transportation impact by 75,000kg-CO2 of land transportation. |

Eco-Driving Workshops |
|
|
|
| In June 2010, we held Eco-Driving Workshops for the purpose of reducing fuel use and CO2 emissions while driving as part of our efforts for the environmental awareness month, which a total of 4,583 people attended. |

Received an Excellence Award for
"Eco-Driving Contest 2010" |
|
|
|
| The Kagoshima Sendai Plant received an Excellence Award for the Eco-Driving Contest 2010 (sponsored by the Ministry of the Environment and the Environmental Restoration and Conservation Agency (Japan)). The award was based on overall original and ingenious environmental conservation activities such as hosting an internal eco-driving contest and attaching enlightening bumper stickers on all company vehicles. |

Growing "Green Curtains" |
|
| The "Green Curtain" activity refers to covering windows by growing climbing plants such as bitter gourd and morning glory. It not only prevents room and outside surface temperatures of buildings from rising by blocking the strong summer sunshine, but also helps to cool down room temperature via foliage transpiration. The Kyocera Group grew Green Curtains at 18 plants and offices in Japan and two locations overseas in FY2011. The total mass of Green Curtains grown by the Kyocera Group in FY2011 accounts for a length of 616 meters and an area of about 2,479m², or about the equivalent area of 9.6 tennis courts. |

Clean Energy Use |
|
KYOCERA Document Solutions Europe B.V., KYOCERA Document Solutions Belgium N.V., KYOCERA Document Solutions Deutschland GmbH and KYOCERA Document Solutions Inc.'s sales companies in Europe use clean energy generated by hydraulic power or wind power in their offices.
Shanghai KYOCERA Electronics Co., Ltd., a manufacturing plant in China, has been using clean energy generated by wind power every year since 2006. This use of green power together is equivalent to a reduction of annual CO2 emissions of approximately 1,260 tons. |
