Solar power generation installation examples
-
01.Introduction of solar power generation through the PPA (Power Purchase Agreement) method at the Tendo Factory
At the Tendo Factory (Tendo City, Yamagata Prefecture), we have decided to introduce a solar power supply system using 700kW solar panels under the PPA system, which is expected to reduce CO2 emissions by the equivalent of 378t-CO2 per year.
-
02.Self-consumption solar power generation system at Ishinomaki Factory
The Ishinomaki Plant (Ishinomaki City, Miyagi Prefecture) began generating electricity using solar panels with a capacity of 383.68 kW in March 2023. This is equivalent to reducing CO2 emissions by 214 t-CO2 per year.
-
03.Self-consumption solar power generation system at the Fukushima Factory
In 2023, we installed new solar panels with a capacity of 532.8kW and began generating electricity in August.
This is expected to result in a CO2 reduction equivalent to 266 t-CO2 per year. -
04.Generation of renewable electricity at Solar Park Fukushima
We are contributing to the local community through the reconstruction of Fukushima and the reduction of environmental impact by renewable energy.
Installation area 1,454㎡
Generating capacity 3026ｋｗ
Annual power consumption of 880 typical households -
05.Installation of solar panels at headquarters
Solar panels are installed on the wall of the head office building. The generated power is used for air conditioning in the head office building and is environmentally friendly.
Kanagawa Factory Improvement Case
At the Kanagawa Plant, we used a steam boiler (heavy oil A) as a heat source for laminating presses and humidifying clean rooms, but switched to a gas boiler in January 2020. By switching from heavy oil to city gas as fuel, we have been able to reduce the amount of NOx (nitrogen oxides) generated and curb CO2 emissions, contributing to a reduction in the environmental impact.
Effect: CO2 reduction of 75 tons per year (15% reduction compared to conventional methods)
Reducing power consumption in the energy building (Vietnam factory)
The energy building's power consumption was reduced by 1.312 MWh and 887.6 t-CO2 by prioritizing the operation of energy-efficient turbo chillers, controlling the number of pumps and discharge pressure according to the season, and increasing the heat exchange rate by replacing the filler in the cooling tower.
Compressor upgrade and inverter control to reduce electricity consumption
The compressors have been updated from old, low-efficiency machines to high-efficiency equipment, and the entire compressed air supply system has been rebuilt. When using multiple compressors, the optimum number of compressors is automatically selected and operated according to changes in the amount of air used and the factory's operating rate, thereby achieving energy savings. Furthermore, by combining them with inverter compressors, energy savings have been dramatically improved.

Reuse of recyclable resources
Resource recovery (rare metals) in our own factory
We have set up a recycling plant within our own factory to recycle industrial waste generated within the factory.
Some waste products are being recycled to recover rare metal resources.
By collecting and recycling industrial waste instead of disposing of it as garbage,
This helps prevent the depletion of rare metal resources and contributes to protecting the global environment.
Turning bakelite boards from waste into valuable resources (Thang Long Factory, Vietnam Factory)
Bakelite boards are used as backing plates in drilling, contouring and laser processes.
White bakelite, which accounts for 95% of bakelite, will be used to make picture frames from July 2023.
It has become a valuable commodity because it can be reused.
This will result in a reduction of 2,100 tons of waste per year.
