Our company is located in the north east part of the Kofu basin in Yamanashi Prefecture. This area is famous for fruits like grapes and peaches. It is also rich in nature and blessed with many seasonable flowering plants. All our employees want to harmonize with nature while still developing for the future. To preserve this nature “we” Enzan Factory Co. Ltd. will strive to protect the environment.

Installed a solar power system
Manufacturing factories like us consume large amounts of power. Hitherto we are depended on electricity and now we think we should contribute to the stabilization to make more electricity.
In Yamanashi, the hours of sunlight is longest in Japan and we started generating solar powers using this equipment.
Module output 165w
Quantity of the module 288
Electric power generation 47.52kw
Past results and real-time electric power generation
Below is an actual electric power generation and changes from the past.
Amount of electric power generation (kw/month)
We use environment-friendly wastewater treatment system
Closed system for wafer processing wastewater by ceramic filter
Industrial waste water which contains dusts is discharged a lot because we squirt ultra pure water during grinding and dicing wafer to cool and clean (remove dusts). We built an environment-friendly closed system that does not discharge the wastewater to rivers by filtrate industrial wastewater with ceramic filter (precision filter apparatus made from fine ceramic) and reuse this clean filtrate.
Merit of environment-friendly ceramic filter
- Durable and long life
We can repeatedly regenerate and reuse clogged filter for over 10 years. The filter does not become waste.
- High recovery rate
It can recover 99.9% of the processing wastewater and reuse it.
It does not need chemicals such as flocculants because it filtrates with microfiltration membrane made from fine ceramics and also pore size is highly controlled.
Changed the factory indoor lights that are used continuously for 24hours to LED
Replaced fluorescent lights to LED at both the head office and the PDM Center as one of our energy-Saving activities.
We think our mission is to think about how to continue our business while being friendly to the environment and in harmony with nature for children who will lead the next generation.
