basalt fiber qualifies as a sustainable material because its production involves less energy than the alternatives of fiberglass and steel. Each kilo of basalt fiber used in place of the corresponding amount of steel saves over 9kWh of primary energy. Basalt fiber is also a biocompatible material, which means it has no limitations to recycling.
