Message from KOYOH Co.,LTD.


As a result of many years of research, ECOBIO-BLOCK(EBB) has successfully infused “fermented soybean” Bacillus (a useful microbe) for water purification into a cement paste in March 2000. Due to this, it is possible to transform the use of concrete, which is considered harmful to the environment, into a product for environment cleanup and restoration such as in many public utility works.

This has been praised as a worldwide breakthrough and applications are currently being developed, not only in Japan, but also in many other countries. We will continue to improve this technology by combining it with the technologies of other countries, leading to a more advanced New ECOBIO-BLOCK.
