Japan (TGW) – Japanese company Suntory Ltd. said this week that it has created an alternative artificial soil, named Pafcal, that will help keep cities green.
The soil is designed to ease the “heat-island” problem of rising temperatures in urban areas.
Some 450 grams of the sponge-like material, which is made of the synthetic substance urethane, can be put to the same use as one kilo of soil, the company said. Leafy plants growing in the synthetic soil can reduce the roof temperature by 10 degrees Celsius (18 degrees Fahrenheit).
