Tokyo's Fake Soil For Green Roofs
As reported in Gizmodo…
In tightly-packed cities with a distinct lack of trees such as Tokyo, planting trees on the roofs of buildings is a common practice. In fact, every new medium-sized building in Tokyo is required to plant gardens on the roof. The problem? Soil is heavy and dense. The solution? Have a brewery invent a new fake soil, of course.
Yes, it’s true. Suntory has created Pafcal, which is lighter and more solid than soil. How light? 450 grams of this sponge-like material is equivalent to 1 kilogram of soil.
For relaxing times, make it Suntory time.
