This is our revolutionary Japanese greening system developed by Kawada Industries, Inc. that has been designed for building rooftops and roadside greening projects. It uses natural rainwater and recycled waste material to promote maximum vegetation growth, which minimises maintenance and water use. Unlike other competing systems, which are often merely superficial examples of “green washing” to give the appearance of being environmentally friendly, the Midori-chan™ system is truly green throughout. Our engineers in Japan have developed this innovative technology to encourage greener, cleaner communities and help companies create a sustainable future for all.

The Midori-chan™ system operates in a natural way by cleaning, storing and recycling rainwater, before supplying it to more than 100 potential species of plant. The ultra-lightweight system transfers moisture from water storage units via the thermal energy balance in the soil. A specially regenerated layer of charcoal filters the rainwater before it is drawn up into the plants’ roots.

The ultra-lightweight Midori-chan™ system harnesses the power of nature by making the most of rainfall, creating a truly green, sustainable space for your project, whatever its size.

• Rainwater is cleaned as it filters through Kawada’s special capillary-action soil mix, plus a layer of regenerated charcoal, into water storage units
• The water storage units are locked and interlinked, much like ice-cube trays, and are designed to enable excess water to drain away naturally
• Resin nets above the water storage units enable the hassle-free installation of bags of regenerated charcoal
• Vegetation roots won’t access the filtered rainwater directly due to a root barrier layer between the resin net and regenerated charcoal bags
• The water storage units ensure an air gap exists between the stored water surface and the regenerated charcoal bags
• Surface soil starts to dry during hot weather
• The layer of regenerated charcoal below the soil absorbs water vapour from the air gap and feeds water steadily to the roots above
