From a rice mill to a trusted RHA exporter
What began as a rice milling operation in Sambalpur grew into a specialist manufacturer of Rice Husk Ash and rice husk products. We recognised early that the husk left over from milling — too often burned as waste — was in fact a valuable source of high-purity amorphous silica and clean biomass energy.
Today we process rice husk into six grades: micronized RHA ground powder, steel-grade granules and pellets, raw husk, rice husk powder and biomass fuel pellets. Each is produced to a consistent specification, independently NABL-tested, and backed by reliable bulk capacity and full export documentation.
Our customers are procurement and technical teams who need certainty: a material that performs the same way every delivery, with paperwork that stands up to scrutiny at home and at the port.
