Developed from Real-World Construction Challenges
Midori-chan was developed over 25 years ago as part of Kawada Construction’s effort to improve the sustainability of its own operations.
In the production of precast concrete, large volumes of wooden formwork are used and typically discarded. Rather than relying on third-party disposal, Kawada engineered a solution to repurpose this material—transforming it into a mulch-based growing medium.
Through continued development, including biological enhancements, this process evolved into a reliable vegetation system capable of supporting plant growth with minimal external inputs.
Today, Midori-chan represents a proven approach to integrating sustainability directly into construction and infrastructure projects.
