Circular Biorefinery · Telangana, India

Turning agricultural
waste into specialty
materials

Fluxara converts rice husk ash — an abundant agricultural by-product — into high-performance precipitated silica and fine precipitated calcium carbonate used in tyres, sealants, plastics, and specialty coatings.

At a Glance

A zero-waste chemistry
platform built for India

Our Day 1 plant produces 20 MT/day of precipitated silica and 30 MT/day of PCC — every tonne of output is a tonne of agricultural residue diverted from open burning.

Products

Two high-value materials,
one circular process

Our chemistry converts a single input — rice husk ash — into two distinct product lines that serve global markets in rubber, construction, and specialty chemicals.

⬡
Precipitated Silica (PS)
Amorphous SiO₂ precipitated from sodium silicate solution using internally captured CO₂. Available in standard, highly-dispersible silica (HDS), and food/dental grades (FSSAI E551 pathway from Year 3).
Green Tyres (HDS) Rubber Compounding Animal Feed Dental / FSSAI E551 Food Grade
◈
PCC — Precipitated Calcium Carbonate
Fine CaCO₃ (0.5–2 µm, coated grades for PVC and paint) produced as an obligatory co-product of our NaOH recovery loop. Surface-coated variants (stearic acid, OCC) available for high-value sealant and plastics applications.

♻
Circular By-Products
Nothing leaves as waste. Desilicated RHA residue is sold to brick kilns. Surplus CO₂ from rice husk combustion is eligible for Biochar Carbon Removal (BCR) credits via Puro.earth.
Desilicated Residue → Bricks CO₂ → BCR Credits Zero Liquid Discharge
How It Works

A closed-loop chemistry
that makes two products

Our process integrates four reactions into a single closed loop — CO₂ from combustion precipitates silica, and the sodium carbonate by-product is continuously recycled into fresh NaOH while making PCC.

🔥
Husk-fired heat
Rice husk from our own mills fires three packaged heaters: two make clean hot air for the dryers and one heats thermic oil for the evaporator. No steam and no boiler. The silica feed is certified amorphous rice-husk ash (RHA), bought and tested lot by lot.
⚗️
NaOH Leaching
RHA is dissolved in a 10% NaOH solution at 90°C, converting SiO₂ into soluble sodium silicate (Na₂SiO₃). Desilicated residue exits for brick kiln use.
💨
CO₂ Precipitation
Flue CO₂ captured from combustion is sparged into the sodium silicate solution, precipitating high-purity amorphous silica (PS) at controlled pH and temperature.
🔄
Causticisation → PCC
Sodium carbonate from the precipitation step reacts with slaked quicklime, recovering NaOH back into the circuit while simultaneously precipitating PCC as a co-product.
🌡️
Washing, drying & evaporation
Membrane filter presses squeeze and wash the silica and PCC cakes; spin-flash dryers turn the cakes into powder. A 4-effect evaporator returns strong caustic to the leach and clean condensate for washing. Zero liquid discharge from Day 1.
🏭
Surface Treatment & Packing
PS is milled to each grade (standard, feed carrier, toothpaste, battery separator; HDS and food grades from Year 3). PVC and paint-grade PCC gets a stearic coating. Bagged in 25 kg valve bags or 1 t FIBCs.

Project Finance

₹45.5 Cr bank case
debt service covered 1.68× or better

One term loan at a commercial 9% — no reliance on unverified concessional schemes. Promoters bring ₹9 Cr (₹4 Cr land in kind + ₹5 Cr cash). Only what the plant needs on Day 1 is financed (including the 500 kWp rooftop solar); residue granulation (Y3), the HDS / food-grade kit (Y2), the battery-separator mill (Y1) and the HDS / food spray dryer (Y2) are bought later from operating cash.
