Environmental Activities


Thanks to the factory, we are blessed with the surrounding environment as a manufacturing factory. Surroundings are surrounded by trees and private houses are not nearby. We are proud to be able to produce in this natural environment, and at the same time we would like to continue to make products with due consideration to the environment.

Around the beginning of the Meiji period, a good quality Kaito feldspar was discovered at the foot of Mt. In the crushing of the feldspar, a cylindrical tromel made of iron was used in Taisho era. Using the water of the Sasagi River flowing from the mountain, we moved the water mill and moved the tromel. Also surprisingly when I was not using Tromel, I used a water mill as a power source for a jaw crusher. It was exactly the ultimate energy conservation practiced at that time. I think that we have been strongly involved with the production of tromel and sludge wastewater treatment equipment etc. from old days without considering our environmental situation so much.
Troubles Indeed the productivity and efficiency has transformed the water turbines into electric motors, but the spirit of the environment that has been handed over to unconsciousness has not changed. (Reference film)

It is now desired that a global society be protected and a sustainable society to be created and there is no time to be sought. Recycling and reusing things like waste / landfill disposal. We will contribute even a little in fields such as creation of other energy to reduce fossil fuel consumption, development of equipment to store surplus energy. Although there are some areas already practiced, we would like to contribute even more strongly and consciously.

I think that we do not see everything about our machines first. With our machine you can not make the final product as directly seen in the general market. However, I think that it is a machine that plays the role of so-called shade of such other people, the role under the rim, which is made of raw materials that can use our machine and produce good products using that raw material It is.

定期的に清掃活動の実施 定期的に清掃活動の実施

近隣道路のゴミ拾いと草刈り清掃 近隣道路のゴミ拾いと草刈り清掃


Picking up cans, bottles, poly bags, trash etc. thrown by car drivers at the sides of road..

The crime of littering along roads never end. There are empty cans, bottles, pet bottles after driking coffe, soda, juices, water, also lunch food ware in poly bag after having lunch, empty paper or vinyl bags after eating snaks scattered road sides thrown out of windows by drivers. Picks up them and clean them up, but after a few days again same scenery be seen. The drivers who does not litter never litter, the drivers who litter always litter. The problem of littering on the road is this type of drivers "always litter". There is a proverb that the person who throw away will be thrown away himself someday. We want to stop the litterring and keep our precious place full of nature clean always.
