Suntory, the Japanese company better known for whiskey and other beverages, issued a press release announcing it had created a way to grow green roofs and green walls without soil.
From the press release: "Suntory brings its unique roof-greening system, Midori no Yane (literally, green roof), and wall-greening system, Hana no Kabe (literally, wall of flowers) onto market on March 3, 2008. "
The synthetic soil, known as Pafcal, is made from urethane and is far lighter than organic soil. Wisegeek.com notes: "It looks much like regular soil, and can be used for a variety of planting products. The material is meant to help meet new Tokyo building regulations, which insist that any new building over a certain size limit must have a roof garden to offset carbon dioxide production. "
Let's raise our glasses to Suntory for creating a lighter weight material for growing and promoting green roofs.
