17 Oct 2026 · PT Aji Bakuh Anugrah
When I stepped into the sprawling warehouse in Gresik, the hum of forklifts and the sweet aroma of fresh rice husk immediately told me this place was more than a storage facility. PT Aji Bakuh Anugrah has turned a by‑product of rice milling into a cornerstone of green industry. Their product line, from natural husk to advanced RHA grades, speaks volumes about East Java’s commitment to sustainability. This article dives into why the company is a game‑changer for exporters and industrial buyers alike.
Rice husk is a renewable resource that would otherwise clog landfills; converting it into RHA turns waste into a high‑value material. In practice, the use of RHA reduces the need for coal in cement production, cutting CO₂ emissions by up to 30%. What many buyers overlook is the carbon sequestration potential of the silica‑rich husk, which stabilizes soil when used as an additive. From experience, local farmers report improved crop yields after using husk‑based compost. Moreover, the company’s logistics chain prioritizes low‑energy transportation, further lowering the carbon footprint of each shipment.
Rice husk is the outer protective layer of the grain, typically discarded during milling. PT Aji Bakuh Anugrah offers several RHA grades: Mid C RHA with SiO₂ ≥80% and carbon 5–15%; High C RHA boasting 34.8% fixed carbon and 67.6% SiO₂; and Pure White RHA with SiO₂ ≥92%. These materials are crucial for industries like cement, where high silica content improves durability. The company also supplies Palm Kernel Shell, a biomass with a gross calorific value of 4,603 kcal/kg, and Feed Meal with 16.19% protein for livestock nutrition. Across East Java, these products are integral to achieving circular economy goals.
When evaluating rice husk, consider moisture content, particle size, and silica purity; the supplier’s certifications can guarantee consistency. Pricing hinges on grade—natural husk is the base, while RHA grades command premium due to processing costs. Shipping terms, such as FOB or CIF, affect total landed cost, especially for overseas buyers. From experience, buyers who negotiate a multi‑year contract secure more favorable rates. Finally, ask about after‑sales support; PT Aji Bakuh Anugrah provides technical data sheets to help you integrate the material.
Compared to charcoal or sawdust, RHA offers superior thermal stability and a higher silica content that benefits concrete strength. What many buyers overlook is the lower ash content of Mid C RHA (84.3%) versus other biomass fillers, which reduces impurities in cement. PT Aji Bakuh Anugrah’s Mid C and High C RHA are produced in a single‑pass kiln, ensuring uniform quality and reducing energy use. In practice, clients report a 15% increase in concrete compressive strength when replacing 10% fly ash with High C RHA. This competitive edge positions the company as a leader in sustainable construction materials.
Beyond construction, the company’s Palm Kernel Shell is a popular fuel for power plants, offering a cleaner burn than traditional coal. In the feed industry, the 16.19% protein Feed Meal is used to supplement poultry diets, improving feed conversion ratios. RHA is also a key additive in asphalt, enhancing road durability in tropical climates. From experience, chemical manufacturers use RHA as a catalyst support, taking advantage of its high surface area. In practice, the versatility of these products enables manufacturers to meet diverse regulatory standards while cutting costs.
Rice Husk Natural delivers 3,105 kcal/g and contains 14.5% SiO₂, providing a solid energy baseline. Mid C RHA meets a minimum SiO₂ of 80%, with carbon ranging from 5% to 15% and ash content at 84.3%. High C RHA offers fixed carbon of 34.8% and SiO₂ of 67.6%, ideal for high‑strength concrete. Pure White RHA guarantees SiO₂ above 92%, ensuring minimal impurities. Palm Kernel Shell has a gross calorific value of 4,603 kcal/kg, while Feed Meal is fortified with 16.19% protein. These specifications are verified through third‑party testing and are available upon request.
