Our Efforts

Reducing Greenhouse Gas Emissions

Improved compressor operation efficiency
[Tamamura Plant, FUKUSHIMA TAIYO YUDEN CO., LTD., and TAIYO YUDEN (GUANGDONG) CO., LTD.]

We run multiple compressors to supply compressed air to production lines and are making various efforts to increase their operation efficiency.
Tamamura Plant began to use compressors that use an inverter to control motor speed.
FUKUSHIMA TAIYO YUDEN CO., LTD. and TAIYO YUDEN (GUANGDONG) CO., LTD.
reduced the load of compressors by reducing their air discharge pressure.
These improvement efforts resulted in optimal compressor operation reducing electricity consumption.
The amount of GHG emissions reduced as a result was 833 t-CO2e per year.

Reduced energy consumption of freezers by improving operation efficiency
[Haruna Plant and KOREA TONG YANG YUJUN CO., LTD.]

Haruna Plant used to operate three freezers alternately, but upon examining their operation status, integrated them into a modular inverter chiller, which reduced energy consumption.
KOREA TONG YANG YUJUN CO., LTD. reduced energy consumption of a freezer by updating it to a low-pressure centrifugal chiller with better operation efficiency.
The amount of GHG emissions reduced as a result was 400 t-CO2e per year.

Reduced energy consumption of air conditioning systems by using a heat shield paint
[TAIYO YUDEN CHEMICAL TECHNOLOGY]

A plant roof has nothing to block direct sunlight. Its surface gets hot making the inside hot too. As a result, air conditioning systems have to be set higher which consumes extra energy. To suppress the increase of the roof temperature, we coated the entire roof with a special heat shield paint. This has lowered the surface temperature by approximately 8°C and reduced the energy used by the air conditioning systems.
The amount of GHG emissions reduced as a result was 4 t-CO2e per year.

Reducing Water Use

Water conservation by recycling wastewater [TAIYO YUDEN Mobile Technology]

TAIYO YUDEN Mobile Technology has launched a system in which water used for cutting, which used to be discharged, is collected, cleaned by filters, and reused in the production process. This significantly reduced the amount of water used for cutting.
The amount of water reduced as a result was approximately 54,000 t per year.
