Initiatives for Resource Conservation and Biodiversity

Automatic inspection using Ishikawa Sanken image camera

We are working to improve production efficiency by changing visual inspections by people to automatic inspections using image cameras.
In 2015, we reduced the number of employees by approximately 30, including by actually adopting image camera inspections for internal visual inspections and by adopting image camera inspections with or without JCR in the JCR process.

Introduction of Ishikawa Sanken Energy-Saving Air Conditioning Equipment

With the use of CFC-free 22 (*) as a machine, we replaced the air-conditioning equipment in the refrigerator with new energy-saving equipment, which has resulted in more energy savings than the previous equipment.

Old system: 34,177 kWh/year
New system: 21,466 kWh/year 37% reduction

※Fluorocarbon-free 22: Complete elimination by 2020 of specified CFCs (HCFC) that are highly ozone-depleting

Contribution to biodiversity

Beech autochthonous site on the Hiromatsu plant site "Beech trees (six trees)" were found on the site of the Ishikawa Sanken-Horimatsu Plant. This beech tree is found to be an environmentally friendly tree and is a rare tree that grows in clusters on the lowest land of Japanese beeches, at an altitude of 33 meters. Ishikawa Sanken believes that protecting the trees of this beech will lead to the conservation of the natural environment. In addition, in order to leave this rare tree to later generations, we will change our on-site preparation plan and work to improve and conserve it.

Initiative of My Water Bottle Campaign

Since August 2019, all of our domestic business sites have been implementing the "My Water Bottle Campaign Initiative" as the first initiative to reduce the amount of plastic waste generated in-house. In particular, we will curb the volume of waste in-house "PET bottles" and "disposable plastic cups," thereby contributing to the realization of a sustainable society that SDGs aims to achieve.
(Reference) Waste of PET bottles: 156,000 (approx. 4 tons)/year (Head Office, Tokyo Office, Osaka Branch, Nagoya Sales Office)

Resource conservation Separate collection of cardboard boxes and valuable materials Yamagata Sanken

As energy-saving and resource-saving activities, since September 2021 we have sorted and collected cardboard boxes that used to be solid waste fuel (RPF) and converted them into valuable resources.
Disseminated information to all employees and requested their cooperation. The company-wide sorting is carried out to recycle waste.
The monthly average collection of 2,000 kilograms has produced a significant effect, and we will continue this effort as an effort to conserve resources.

Reuse and Recycling of Plastic Cases Yamagata Sanken

We have been working on the recycling of wafer cases (plastic) since October 2021.
Until now, we have been carrying out the recycling process (recycling) as industrial waste, but we are currently implementing the reuse process (reuse) of wafer cases in cooperation with recycling companies and wafer manufacturers.
