Rice Husk Ash Surabaya – PT Aji Bakuh Anugrah

PT Aji Bakuh Anugrah supplies high‑quality Rice Husk Ash (RHA) to businesses across Surabaya and the wider East Java region. Our locally sourced ash is produced from abundant rice husk waste, turning a by‑product into a valuable industrial material. With a focus on sustainability and consistent performance, we support construction, manufacturing, and agricultural sectors alike.

When sourcing Rice Husk Ash in Surabaya, start by verifying the supplier’s certifications and track record in biomass processing. Look for consistent particle size distribution and reliable moisture content to ensure seamless integration into your production line. A supplier with a local warehouse in Gresik or Surabaya can reduce transport costs and delivery time. PT Aji Bakuh Anugrah provides transparent batch testing reports and flexible order volumes, which are essential for both small and large projects.

Our Mid‑C Rice Husk Ash meets a minimum of 80 % SiO₂ and contains 5‑15 % carbon, ideal for pozzolanic applications. The High‑C variant offers 54.2 % carbon and 43 % SiO₂, delivering higher reactivity for specialized cement blends. For premium purity, the Pure White RHA guarantees at least 92 % SiO₂ with negligible carbon residue. Compared to natural rice husk (3105 kcal/kg, SiO₂ 14.5 %), our ash provides a stable, low‑calorific material suitable for industrial use.

Rice Husk Ash (RHA) is the fine, silica‑rich residue obtained after controlled combustion of rice husk, a by‑product of rice milling. In East Java, abundant rice production supplies a continuous feedstock, and PT Aji Bakuh Anugrah processes the husks in Gresik using low‑oxygen burners to preserve silica structure. The resulting ash is a lightweight, amorphous material that differs from traditional ash due to its high purity. This locally sourced RHA is marketed throughout Surabaya and surrounding industrial zones.

Utilizing RHA transforms agricultural waste into a value‑added product, reducing landfill pressure and open‑burning emissions. The high silica content can replace a portion of Portland cement, cutting CO₂ emissions associated with cement manufacturing. Because the ash is inert, it can be safely incorporated into soil amendment programs, enhancing water retention without adding heavy metals. PT Aji Bakuh Anugrah’s sustainable processing aligns with Indonesia’s circular economy goals.

Construction firms in Surabaya employ RHA as a pozzolanic additive in concrete, improving strength and durability while lowering the carbon footprint. The material is also blended into high‑performance bricks and tiles, where its fine particles promote uniform firing. In the steel industry, RHA serves as a refractory filler, and in agriculture it acts as a silica supplement for rice paddies. Our product line, including Mid‑C and Pure White RHA, caters to these diverse use cases with consistent quality.

Compared to fly ash, RHA offers a higher amorphous silica content, delivering superior pozzolanic activity at lower carbon levels. Unlike slag, which requires high‑temperature processing, RHA is produced at temperatures that preserve energy efficiency. When measured against Palm Kernel Shell (GCV 4603 kcal/kg) and Feed Meal (protein 16.19 %), RHA provides a non‑fuel, mineral‑rich alternative for cementitious blends. Selecting RHA from PT Aji Bakuh Anugrah ensures you receive a product with verified silica percentages and minimal impurities.

FAQ

PT Aji Bakuh Anugrah supplies a certified laboratory report with each batch, detailing SiO₂ percentage, carbon content, and particle size distribution, allowing you to confirm the specifications before use.

Standard shipments are dispatched within 24 hours and usually arrive in Surabaya within 2‑3 business days, depending on the order size and transport conditions.

Yes, RHA can be blended with fuels such as Palm Kernel Shell to adjust calorific value or silica content; however, the mixture should be evaluated for combustion behavior to maintain optimal performance.
