Environment-related Business

Extensive efforts to conserve and restore the natural environment to
preserve the beauty of all Earth's organisms

To support humanity, all Earth's organisms, and the global environment, Tsuchiya engages in environment-related business which aims to support habitats for all Earth's organisms. Tsuchiya's businesses include those related to the creation of biotopes, soil remediation, the protection of natural ecosystems, and efforts to conserve energy by making maximum use of sunlight and other natural energy sources. We believe that in order to provide a more beautiful future for our children, in addition to developing technologies, we need to preserve and restore the natural environment as one of our missions.

Creation of biotopes

Creating rich natural environments

In order to restore a local ecosystem, it is important to conduct a survey of the target site in advance. We analyze environmental data to identify the characteristics of the environment to be restored. We then provide integrated services that cover all phases of biotope creation, including planning, surveys of biological species, data analysis, design, and construction, in addition to promoting the conservation, and restoration of ecosystems.

* The origin of the word "biotope" (Biotop)
A place where indigenous species can continue their daily activities.
It is a coined word, which combines the Greek words bios (living thing) and topos (space/place) and is written out in German.

Breeding fireflies

Restoring old streams that provide habitats for fireflies

Tsuchiya has developed a system invented for breeding Japanese fireflies by combining river environments suitable for growing fireflies with facilities for raising firefly larvae. "HOTA ROOM" where an experiment is underway that aims to raise Japanese fireflies from larvae.

* Hotaroom
The nurturing machine for Japanese fireflies. The lower unit is loaded with a water temperature control and water cleaning system. The flight of the Japanese fireflies can be observed in this dome and people can experience the wonders of the natural environment.



Soil remediation

We think about the earth again, and pass down beautiful nature to the future.

We clean the soil and promote the recovery of nature.
This can be realized by soil pollution improvement technology.
We think about the future of nature, starting by observing the earth.
Using soil pollution improvement technology, which has the main roles of the surveying, research and processing of soil and ground water, we work on the preservation of the irreplaceable earth.

We think about protecting the environment, starting at soil pollution improvement technology.

Water and soil are necessary for people and nature to coexist.
To return these things to their natural state is an issue that needs to be resolved rapidly, if we are to consider the future of human living.
TSUCHIYA have accumulated a track record in the research and processing of soil and ground water and play an active part in the research and development of soil improvement technology.
We are preparing the best answer to protect earth's environment and, furthermore, the future of the children, who will take on the next era.

TSUCHIYA's work in soil pollution improvement technology

Tsuchiya and the latest technology from Züblin.

Using proprietary technologies provided by Züblin, a leading German soil-remediation company, Tsuchiya can remediate a wide range of pollutants, from VOCs to heavy metals and oils.

Züblin U.T.

Züblin U.T., a subsidiary of the integrated construction company, Züblin AG, is an environmental technology company based in Stuttgart, with branches in Berlin, Chemnitz, Dortmund, Hamburg, and Nuremberg. The company conducts start-to-finish construction, installation, maintenance and cleanup operations using equipment at company- owned factories. Its cleanup technologies have been used successfully in more than 1,000 cases internationally, which has earned the company recognition as a leader.

Designated Investigation Organization of the Soil pollution Situation

Since the soil pollution act came into force in 2003, the direction of the soil and ground water pollution policies were indicated.
In the soil pollution problem, what is thought to be important is the suitable assessment and reduction of risks on people's health and living environments, as determined from the influence of the presence of environmental risks of polluted soil and polluted ground water.
