PT Aji Bakuh Anugrah delivers industrial-grade Rice Husk Ash (RHA) engineered for maximum purity and consistency, serving as a critical raw material for advanced manufacturing. Our production facility in Gresik, East Java, utilizes proprietary calcining technologies to produce Mid Powder RHA with an impressive 88.6% ash content and 69.2% SiO2 concentration. This specific grade ensures a uniform particle size distribution that enhances mixing efficiency in cementitious blends, providing a reliable alternative to traditional silica sources while maintaining strict quality control standards.

For applications requiring high reactivity and pozzolanic activity, our Low C RHA stands out with an exceptional 91.4% SiO2 content and minimal 1.19% ash residue. This ultra-pure fraction is ideal for high-performance concrete and refractory products where carbon interference must be strictly minimized. The technical precision of this grade allows engineers to predict material behavior accurately, ensuring that the final product meets rigorous international construction and safety specifications.

We also offer specialized Mid C RHA and High C RHA variants tailored for diverse industrial needs, such as ceramic glazes and abrasive manufacturing. The Mid C RHA features a balanced composition with 69.3% SiO2 and 84.3% ash, providing optimal viscosity control in slurry applications. Conversely, the High C RHA, containing 34.8% Fixed Carbon and 67.6% SiO2, serves dual purposes as both a raw material and a fuel source, offering cost-effective solutions for integrated production lines that require thermal energy input alongside silica supply.

Beyond our core RHA products, our comprehensive biomass portfolio includes Rice Husk Natural with a calorific value of 3105 kcal/g and Palm Kernel Shell with a Gross Calorific Value of 4603 kcal/kg. These fuels, alongside our Feed Meal product with 16.19% protein content, demonstrate our capacity to supply multi-sector clients with verified technical data and consistent quality.
