Midori-chan is a revolutionary system designed to maximise vegetation growth and recycle waste, while dramatically minimising water usage. Our engineers at the Kawada Group in Japan developed the system to meet the demands of greener and cleaner communities. Our development of Midori-chan is consistent with our corporate mission of "building a better tomorrow". Kawadas technological innovations have ranged from transportation, energy, information systems, and mechatronics. Now, our future depends on technologies such as Midori-chan, technologies that reduce CO2 and increase vegetation without draining already limited world water resources.

As part of our commitment to corporate social responsibility, Midori-chan was conceived in the late 1990s. Our goal was to recycle building materials and to ease the heat island effect. Our concept is to increase vegetation without wasting a drop of water.

Midori means "green" in the Japanese language. The word "chan" after "midori" is a nickname given to children in Japanese. Midori-chan is based upon a system in which rainwater is effectively recycled, stored, and supplied to vegetation. The system mimics and improves upon the system of water supply and evaporation that occurs naturally in the earths surface. Special water retention materials grip water vapour. Soil moisture transfer is generated by thermal energy balance in the soil and facilitated by water storage units. Regenerated charcoal cleanses the water through natural water vapour absorbed through the plant roots.
