Rice hulls - a waste product as a game changer for silicate production. Pörner's advanced Bio-Silicate technology enables the efficient and environmentally friendly production of high-tech bio-silicates from rice hulls. The patented process can be used worldwide and offers diverse and sustainable applications.

Whether for the rice farmer, the silicate producer or the silicate user, there are several economic and environmental benefits:

  • Utilization of biological waste
  • Patented RHA treatment process achieves constant product quality
  • Silicates with high purity
  • Sodium Silicates with high weight ratios up to 4.0 SiO2/Na2O
  • Sodium and Potassium Silicates producible in the same plant
  • Reduced CO2 footprint up to 70%
  • Valuable carbon by-product

As a product for the world market, Pörner Bio-Silicates offer a wide range of applications. They are used as bleaching agents in the paper industry, as additives in detergents, paints, building materials, cosmetics, in the tire industry ("green tires") and in construction chemicals. The world market for silicates is growing steadily.

The Pörner Bio-Silicate plant at a glance

The film produced by Pörner Kyiv, presents a 3D model of a typical Pörner Bio-Silicate plant visualizing the overall concept of the plant and the successive production steps. It gives an insight into the innovative design starting with the processing of Rice Hull Ash (RHA) to the final product of Bio-Silicates.
