Evonik, one of the world’s leading silica producers, entered a strategic cooperation with the Pörner Group, Austria, and Phichit Bio Power Co., Ltd., Thailand, to supply sustainable ULTRASIL® precipitated silica to tire manufacturers. The key raw material for the sustainable silica is sodium silicate, which is derived from rice husk ash (RHA), an agricultural waste product, and produced exclusively with green energy.
