Head Office Group

 In step with the renewal of the entrance on the first floor of our Head Office in Togoshi, we replaced the lighting fixtures in the lobby, reception room, and conference room with energy saving versions including ball and inverter type fluorescent bulbs. This will reduce consumption of power for lighting and is projected to lower our CO2 emissions by about 6.8 tons per year. The replacement also improved the workplace environment by nearly tripling the luminosity and giving each room a bright and expansive atmosphere. The Head Office Group is going to continue with its efforts to prevent global warming while planning measures for the initiative based on capital investments, in parallel with its activities to save energy in the operating aspect through COOL BIZ campaign and control of air conditioning settings etc.

Renovation of air conditioning facilities
Toyama Works is taking action to increase the efficiency of energy utilization every year. In fiscal 2008, it renovated the air conditioning facilities for about 800 square meters of space on the first floor of its main building. Before the renovation, the entire first floor was cooled and heated with a single large unit. This was wasteful, because certain areas were air conditioned needlessly. The renovation installed inverter type units in each room for more efficient cooling and heating. As a result, it brought a yearly power savings of 3,390 kWh (about 1 million yen).
In addition, the new system enabled the Works to reduce consumption of A-type fuel oil, which was used in the heating mode, by a remarkable 6,400 liters (about 500,000 yen), and also delivered a CO2 emission reduction of 30.55 tons per year along with more effective energy utilization. The Group plans to renovate the rest of the air conditioning facilities in the Works and implement other initiatives to save energy.

Switch to energy saving lighting fixtures

Hitachi Works switched to energy saving lighting fixtures in fiscal 2008 and realized the following benefits as a result.

1) Change of outdoor fluorescent bulbs (from 40 W to 32 W)
Energy saving effect:about 20% in terms of power consumption
 CO2reducing effect: 160 kg-CO2/year

2) Change from incandescent bulbs to fluorescent bulbs (from 100 W/bulb to 20 W/bulb)
Energy saving effect: about 80% in terms of power consumption
CO2 reducing effect: 208 kg-CO2/year

 

●Construction of flower beds on the grounds of Hitachi Works

 WorksThe Group built flower beds on the grounds of the Works to reduce CO2 emissions by absorbing them and to serve as a place for employee relaxation. The bed is planted with fragrant olive in the middle and flowers of the season around it. The following flowers bloom in each season.
   Spring: narcissus, azalea, tulip
   Summer: morning glory, sunflower, scarlet sage
   Autumn: cosmos
   Winter: pansyHitachi-Ibaraki Group

Hitachi-Ibaraki Group is located in a beautiful natural setting, and the construction of flower beds will enable further contribution to preservation of the natural environment.
The Group is determined to continue installing or replacing the existing facilities with environmentally friendly ones that help to lower CO2 emissions and save energy.

Overseas Establishments

●SMK Electronics(Malaysia)Sdn. Bhd(SMK Malaysia)

SMK Malaysia attaches great importance to environmental problems and took vigorous actions for improvement on this front in fiscal 2008.

Replacement of lighting fixtures and reduction of intermediate lighting
 Previously, the plant lighting arrangement was an unsystematic combination of overall, intermediate, and close lighting, and it was quite inefficient. In response, lighting fixtures were readjusted to maintain and improve brightness in line with regulations while the number of bulbs on the manufacturing floor was reduced by 468. This reduction represented 34 percent of the total number. Besides obviously being good for the environment, it reduced the number of bulbs used for indirect lighting in the entire plant by 558. The measure made the plant arrangement more orderly even as the overall brightness was significantly improved as compared to before the reduction.

The company also derived substantial effects for environmental preservation from measures such as a switch to natural gas vehicles for company cars, increase in electrical efficiency through installation of capacitors, and promotion of recycling by switching to general purpose jigs. For fiscal 2009, it is considering a switch to LEDs for plant lights and is going to continue reinforcing its environmental approaches.


Dramatic improvement inbrightness for the manufactureing floor

 

●SMK Electronics(Phils.)Corporation(SMK Philippines)

SMK Philippines continues to expand common use facilities for production of touch panels, which is steadily rising, while providing for harmonization with the environment. Its main approaches in fiscal 2008 were as given below.

Improvement of the pure water system for etching
Pure water system is indispensable for production of touch panels. Ideas for improvement born by employees greatly reduced the level of alkali acid while substantially increasing the production of pure water.
 Reduction in the use of alkali acid relative to fiscal 2007: 
  –46% (from 200ℓ to 108ℓ )
 Increase in the production of pure water relative to fiscal 2007
81% (from 25.37 m3 to 46 m3)

Installation of inverter type compressors
 The company increased the supply of air while reducing its power costs by a wide margin (18 percent on the year). Employees also made proposals for improvement of the fluorescent bulbs used in production processes.

The company is making a gradual shift to high efficiency bulbs and further efforts to cut the level of power consumption in the plant. In fiscal 2009, it is going to undertake the following activities in order to make the plant even more environmentally friendly.
• Reduction of power costs by studying   more efficient operation of air conditioners in clean rooms
• Switch air conditioners to inverter type in office space


Pure water system for etching

 

●SMK Dongguan Gaobu Factory(SMK Dongguan Gaobu Factory in China)

At SMK Dongguan Gaobu Factory, increased production of plastic molds and the start of full fledged operations in the rubber mold and painting divisions could make it more difficult to implement environmental measures with the existing emission treatment system. For this reason, the Factory installed a new emission treatment system on the roof, where the exhaust ducts from all floors converge. In advance of the installation, it made sure to select system that meets the atmospheric emission standards of Guangdong Province, at the advice of China’s environmental protection agency. The new system puts the exhaust from each floor through first a cotton fabric filter and then an activated charcoal adsorber for adsorption of hazardous constituents contained in it, before expelling air that meets the standards into the atmosphere. Painting residue used to be contained in exhaust from painting facilities. The exhaust is now treated by putting it through a shower type water spray, filter, and activated charcoal adsorber, in that order.
As shown in Table 1, the emission figures after installation of the treatment system are far below the standards set forth in “Guangdong Province Discharge Limits of Atmospheric Pollutants” (DB44/27-2001). The Factory emissions are now clean.
