Environmental Influence and Environmental Performance

Energy Saving and Resource Saving

Regarding energy saving, we are striving to reduce electricity consumption by switching to LED lighting and controlling temperature through air conditioning.
In addition, we are reducing the amount of paper (documents) we use by utilizing IT and promoting a paperless environment.

Waste Reduction

Waste reduction is the field which we focus on. Especially, we increase recycling amount general waste from business activities by subdivision of separation.

Chemical substance management

To comply with the PRTR law enforced in April 2001, we grasp the handling amount and the discharge amount to environment of chemical substance in detail. For the future, we make efforts for rationalization of management and reduction of the discharge amount to environment.
*In 2022, any chemical substance was less than the handling amount which requires notification.

Main Chemical Substances Subject to the PRTR Law in 2022 (unit: ton)
Substance name Handling amount Discharge amount to environment Discharge amount of waste Adhesion amount of product
Atmosphere Soil Water area
KOMAKI PLANT Toluene 0.112 0.112

Ethyl benzene 0.086 0.086
Dichloromethane 0.000 0.000
Manganese and its compound 0.002 0.002

Pollution Prevention

As to pollution (atmosphere, water quality, noise, vibration, a bad smell, etc.), we observe pollution-related law and regulation exactly and strive for further pollution prevention.

Environmental Product

Product Assessment
Product assessment means evaluating the influence which a product has on global environment in trial design phase and mass-production design phase.
We advance to develop products with less loads by evaluating an environmental influence for each of the following items:

  1. Ease of re-resources and processing
  2. Resource saving
  3. Energy saving
  4. Extension of product lifetime
  5. Ease of handling
  6. Safety and environmental preservation
  7. Packing

Envrionmentally-friendly Yoshitake Products

Model: PT-104, PT-200&PT-300&PT-400 Series, and Pumping Trap


This is a mechanical pump to use steam pressure or air pressure as driving source and to transmit condensate with pressurized air. There is no need for electrical equipment and no possibility of cavitation by suction, like motor pump.


Keeping present productive efficiency, these trap can recover condensate prevent condensate retention without water hammer.

Model: Y's Jacket (Yoshitake Thermal Cover)

The product prevents energy loss due to heat radiation and contributes to energy savings.

Green procurement

Following the announcement of the green procurement guideline by the Ministry of the Environment, Yoshitake advance green procurement along with the policy.

Actual achievement of green procurement

  • Promotion of using recycled paper
    We have advanced to use recycled paper to pamphlets such as guidebook and corporate guidance, in-company documents, envelopes, stock forms for computers, copy paper, etc.
  • With partner companies' cooperation, we develop the simplification of packing in the raw material purchase stage and the product delivery stage.

Observance of Laws and Regulations

While there are many environmental laws and regulations including pollution control laws, Yoshitake investigated environmental laws and regulations, and ordinances relating to the environment of related local governments, and have grasped the contents of the environmental laws and regulations applied to our company in detail.
