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.

Since 2002 4U has provided our markets a number of useful high quality components at reasonable prices.

Our strength is based on our relationship with Asia, where the majority of high tech products are made, combined with many years of experience and expertise in improving and adapting products.

Whatever your needs, we will aim to find the right solution, including identification of new products, modification, or development that will meet your requirements and will make life more convenient.

Convenience in our lives is the key word to our mission. Something better, something special 4U and for the benefit of our life.
