Rice Husk Applications

Rice husk biogeneous silica's high SiO₂ content and amorphous structure make it a high-performance additive for agriculture, environmental management, rubber reinforcement, catalyst systems, construction, and sustainable material science.

Key Industry Applications

Amorphous silica from rice husks provides performance benefits across multiple industries.

Application 01

Crop Protection

Silica from rice husks strengthens plant cell walls, providing a natural physical barrier against pests, fungal pathogens, and environmental stress. Silicon-supplemented crops show greater resistance to drought, lodging, and disease pressure.

  • Silicon supplement for paddy, maize, and sugarcane
  • Resistance to fungal diseases and pest damage
  • Improved drought tolerance in water-stressed crops
  • Carrier material for agrochemical formulations
Application 02

Soil Adjustments

Rice husk silica improves soil fertility, structure, and drainage when used as a soil conditioner. It reduces heavy metal toxicity by immobilising metals in the rhizosphere, improving plant uptake of essential nutrients.

  • Soil conditioner for improved drainage and aeration
  • Reduction of heavy metal toxicity in contaminated soils
  • pH stabilisation and cation exchange improvement
  • Organic matter substitute in low-fertility soils
Application 03

Wastewater Treatment

The porous structure and high surface area of rice husk silica make it an effective adsorbent in water purification systems. It removes heavy metals, dyes, phenols, and other industrial pollutants from effluents without introducing toxicity.

  • Adsorbent for heavy metals (Pb, Cd, Cr) in wastewater
  • Removal of dyes and organic pollutants from effluents
  • Filtration medium in water treatment columns
  • Low-cost alternative to activated carbon
Application 04

Rubber & Polymer Reinforcement

Nano-silica derived from rice husks is used as a reinforcing filler in rubber and polymer compounds. It enhances tensile strength, abrasion resistance, and tear performance — offering a renewable, high-performance alternative to conventional silica fillers.

  • Reinforcing filler in tyre compounds and automotive rubber
  • White filler in industrial rubber goods
  • Nano-silica for high-performance polymer composites
  • Masterbatch additive for plastic applications
Application 05

Catalyst Support

High-purity amorphous silica from rice husks serves as a high-performance support material for heterogeneous catalysts in chemical processing. Its large specific surface area and chemical inertness make it ideal for immobilising active catalytic components.

  • Silica support for metal and acid catalysts
  • Catalyst carrier in petrochemical refining
  • Support material for enzyme immobilisation
  • Active silica in green chemistry processes
Application 06

Construction Materials & Sustainable Fillers

Rice husk silica improves concrete strength, durability, and environmental resistance as a pozzolanic additive. As a biodegradable, bio-sourced material, it also serves as a sustainable filler alternative to conventional abrasives and extenders in cosmetics and coatings.

  • Pozzolanic additive in high-performance concrete and cement
  • Refractory additive in insulating castables and kiln furniture
  • Sustainable matting agent in coatings and paints
  • Biodegradable abrasive in personal care and cosmetic products
