Turning agricultural waste into specialty materials
Fluxara converts rice husk ash — an abundant agricultural by-product — into high-performance precipitated silica and nano-calcium carbonate used in tyres, sealants, plastics, and specialty coatings.
Plant under development — commissioning from 2027We are in the pre-commissioning phase. Engineering, procurement, and lab validation are ongoing. This site will be updated as we progress.
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 nano-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 CompoundingAnimal FeedDental / FSSAI E551Food Grade
◈
Nano-PCC (Precipitated Calcium Carbonate)
Nano-sized CaCO₃ 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.
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.
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 nano-PCC.
🔥
Rice Husk Combustion
Rice husk burns at ≤700°C in a controlled thermal heating unit, generating steam heat for the process and producing amorphous rice husk ash (RHA) rich in SiO₂.
⚗️
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 → Nano-PCC
Sodium carbonate from the precipitation step reacts with slaked quicklime, recovering NaOH back into the circuit while simultaneously precipitating nano-PCC as a co-product.
🌡️
MVR Evaporation & Drying
Mechanical vapour recompression (MVR) concentrates streams efficiently. Spray dryers produce the final PS powder. ZLD ensures zero liquid waste discharge.
🏭
Surface Treatment & Packing
PS is surface-treated with CTAB for HDS tyre grade, or left untreated for standard/food grades. PCC receives stearic acid or OCC coating for sealant and plastics markets.

Four lenders — each funding their natural component. ₹14 Cr in concessional government-scheme debt at 3.5–7.5% saves ₹4 Cr in interest over the loan life versus a single commercial bank loan at 10.5%.

Equity · no interest
Land ₹3.6 Cr bought 100% white in Fluxara's name + ₹1.4 Cr cash equity. D:E held at 58:42.
D:E = 58:42
Why each rupee goes to that specific lender
01
TDB stays at exactly ₹5 Cr — not ₹1 more
TDB funds 70% of eligible cost for loans ≤₹5 Cr. Above ₹5 Cr, quantum drops to 50%. Asking for ₹5 Cr means declaring ₹7.14 Cr of process equipment and getting TDB to fund 70% = ₹5 Cr. Asking for ₹6 Cr would require ₹12 Cr of eligible cost claimed under TDB — increasing royalty liability (0.2% of all sales, forever) and risking the assessor cutting back the ask. The ₹5 Cr ceiling maximises quantum-per-rupee while minimising the royalty burden.
02
RDIF's collateral-free nature frees the ₹9 Cr property for LAP
₹7.5 Cr is financed without any mortgage, pledge, or personal guarantee to RDIF. This keeps the promoter's ₹9 Cr commercial property entirely unencumbered — available as collateral for a LAP at 9%. If RDIF required a charge on the property, the LAP would not be possible and the promoter would need to deploy ₹5 Cr in immediate cash instead.
03
LAP as equity keeps Fluxara's D:E at 58:42 — not 71:29
A CGSS bank loan to Fluxara for ₹5 Cr would appear as debt on Fluxara's books, pushing D:E to 71:29 and adding ₹61L/yr to DS. The LAP is the promoter's personal obligation — when the proceeds are infused as share application money, Fluxara sees ₹10 Cr equity. TDB and RDIF assessors see a well-capitalised company at 42% equity. The arbitrage: borrow at 9%, earn 25%+ EBITDA returns — ₹80L/yr net gain per year.

TDB: simple interest on declining balance, 9 semi-annual instalments (₹55.56L principal + declining interest each). RDIF: reducing-balance EMI ₹6.39L/month. SIDBI: reducing-balance EMI ₹2.59L/month. LAP promoter obligation ₹60.9L/yr (not Fluxara DS) — serviced from Fluxara dividends. Total interest paid on all 3 Fluxara loans: ₹331L vs ₹730L for equivalent bank loan — saving ≈ ₹4 Cr.

Land purchase strategy — Kothakota, Wanaparthy
🏛
100% white payment — non-negotiable
Guideline (circle) rate in Kothakota is ~₹4L/acre vs actual market ₹30L/acre. Paying ₹3.12 Cr in cash saves ~₹17L in stamp duty but destroys ₹1.5–2 Cr of TDB/RDIF loan eligibility. The math never works — when ₹14 Cr in concessional loans depend on the registered value, every ₹1 under-declared costs ₹0.50 in lost loan capacity. Pay full by RTGS; claim stamp duty back through TS-iPASS post-DCP.
📋
Buy directly in Fluxara Pvt Ltd's name
Promoters transfer funds to Fluxara as share application money. Fluxara pays seller 100% by RTGS — full consideration in sale deed. This avoids double stamp duty (buying in promoter name and then transferring to Fluxara triggers a second registration). Register on TS-iPASS portal same week as land purchase to lock in incentive eligibility from Day 1. TS-iPASS reimburses ~₹30L stamp duty in Year 2 post-DCP.
🔄
CLU → clean industrial mortgage
Apply for Change of Land Use (agricultural → industrial) with District Collector immediately after purchase. After CLU, land is freely mortgageable. TDB takes first pari-passu charge on land + plant post-CLU. RDIF is collateral-free so does not encumber the land. Clean industrial title also supports Phase 2 financing (₹15–20 Cr second furnace from accruals) where land value will be significantly higher.
TS-iPASS stamp duty reimbursement — process
Step 01 · At purchase
Pay duty, preserve originals
Pay stamp duty (~₹27L) + registration (~₹3.6L) via treasury challan at Sub-Registrar, Wanaparthy. Collect registered sale deed + challan originals. These are the primary claim documents — no duplicates issued.
Step 02 · Same week
Register on TS-iPASS
Register Fluxara at ipass.telangana.gov.in. Get date-stamped acknowledgment — this date locks the project into the incentive schedule. Apply for CLU from Revenue Department, Wanaparthy Collectorate, simultaneously.
Step 03 · Before construction
Udyam MSME registration
File at udyamregistration.gov.in. Fluxara qualifies as Medium Enterprise (investment < ₹50 Cr, turnover < ₹250 Cr). Required for TS-iPASS stamp duty claim and all subsequent state incentive applications.
Step 04 · Month 12
DCP certificate from DIC
Date of Commercial Production triggers all TS-iPASS claims. DCP certificate issued by DIC Wanaparthy on filing of first commercial sale invoice + GSTR return. File promptly — DCP date is the clock start for all claim deadlines.
Step 05 · Within 6 months of DCP
File reimbursement claim at DIC
Submit prescribed form + sale deed copy + stamp duty challan + TS-iPASS acknowledgment + Udyam cert + DCP cert + CA certificate to DIC Wanaparthy. Deadline strictly 6 months from DCP — do not miss it.
Step 06 · 6–18 months after filing
G.O. issued · credit to bank
DIC → District Collector → Commissioner of Industries → Government Order issued. Amount credited to Fluxara's bank. Total reimbursable: ~₹30–31L (₹27L stamp duty + ₹3.6L registration + 25% of CLU conversion charges). Effective net stamp duty cost ≈ zero.
