Rice Husk to
Nano-Silicon

Rice husk is an abundant agricultural byproduct and a natural source of amorphous silica. We process rice husk into high-purity silica and convert it into nano-silicon used in lithium-ion batteries — avoiding expensive synthetic precursors and reducing overall material cost.

How Biomass Is Converted into Battery Materials

Our thermochemical process is designed to preserve material structure while enabling consistent and scalable output.

  • Conversion of rice husk into usable process energy
  • Recovery of high-purity rice husk silica
  • Production of nano-structured silicon for battery anodes

Distributed Biomass Processing System

This distributed model reduces logistics costs and enables rapid scaling across rice-producing regions.

  • Modular production units installed at rice mills
  • No transportation of low-density rice husk biomass
  • Local processing with centralized material applications

Rice Husk Silica & Nano-Silicon Output

Silica and nano-silicon are the primary value drivers, with energy supporting process efficiency.
