PEKANBARU. Thursday (30/4), 8 environmental cadres of Okura ICD planted several types of nutritious vegetable seed on rockwool.
Rockwool is a horticultural growing media made from the natural ingredients Basalt rock and Chalk. These are then melted at 1600° C into lava which is blown into a large spinning chamber, which pulls the lava into fibers like “cotton candy.” If you have ever visited a volcano you have probably seen these fibers flying around in the air surrounding the volcano.
Once the fibers are spun they are then compressed into a mat which is then cut into slabs and cubes. The rockwool granulates are just bales of uncompressed fibers. The process is very efficient, producing 37 cubic foot of wool from 1 cubic foot of rocks.
This activity is initiated to enhance people’s awareness toward environmental preservation. “We think that this program is good and inspiring. We hope that it could give positive contribution toward people,” Slamawati, a cadre, said. ***
