What is a maize starch project report?
A maize starch project report, the most common kind of maize processing project report, is a detailed project report (DPR) for a unit that steeps and wet mills maize to separate starch from germ, gluten and fibre. It sets out the process, machinery, maize buying, project cost, five-year projections, DSCR and break-even a lender needs.
Entrepreneurs and grain traders use it to size the plant and raise a term loan; banks use it to judge whether starch and by-product sales can repay that loan.
Also known as: maize processing project report, corn starch project report, maize wet milling project report, maize starch plant DPR, maize processing business plan.
What a bank checks in a maize starch project report
A starch unit lives on the gap between the maize price and what starch and its by-products sell for. Lenders test that gap first. These are the values in our sample report and why each one matters.
Maize is bought by the tonne and sold as starch after losses in steeping and separation. A report showing a much lower share is usually assuming too high a yield.
Maize arrives in kharif and rabi harvests, and prices move between them. Stock days set the cash credit limit, which is ₹95 lakh in the sample.
Wet milling runs best continuously. A low break-even shows the plant still covers fixed costs and interest when maize is short and output drops.
The debt service coverage ratio (cash available for repayment divided by instalments due) dips in Year 2, the first full year of principal. Banks usually look for 1.2 or more in every year.
Values are the assumptions in our illustrative sample. Your report uses figures for your capacity, maize source and buyers.
Maize processing plant cost: the sample starch unit
The sample report models a 20 MT per day maize starch unit running 300 days a year, or 6,000 MT a year at full capacity. It starts at 60% utilisation, reaches 80% in Year 5 and sells starch at ₹30,200 per MT before GST.
| Land and site development | 29.15 |
|---|---|
| Building and civil works | 83.09 |
| Plant and machinery | 152.15 |
| Other fixed assets | 13.74 |
| Contingencies | 11.76 |
| Preliminary and pre-operative | 7.25 |
| Working capital margin | 31.66 |
| Total | 328.80 |
| Promoter's contribution (25%) | 82.20 |
|---|---|
| Term loan from bank (75%) | 246.60 |
| Cash credit limit (separate) | 95.00 |
| Total project cost | 328.80 |
Term loan at 10.5% with a 6-month moratorium and 54 monthly instalments. All figures are illustrative; plants that add liquid glucose, dextrose or germ oil cost considerably more.
Maize processing manufacturing process (wet milling)
Wet milling separates the parts of the kernel in water. About 82% of a maize kernel is endosperm, which holds the starch, and about 12% is germ, which holds the oil.
- Cleaning
Maize is screened and aspirated to remove cobs, stones, chaff and broken or damaged grain before it enters the steep tanks.
- Steeping
The grain soaks for 28 to 48 hours in warm water carrying sulphur dioxide, which stops fermentation and softens the kernel to about 45% moisture.
- Degermination
A coarse grind frees the whole germ, which floats off in germ hydrocyclones and is washed and dried for sale to oil mills.
- Fine grinding and fibre washing
The degermed slurry is ground finely and passed over pressure curved screens to wash out the hull fibre.
- Starch and gluten separation
Centrifugal separators split the slurry into a heavy starch stream and a lighter gluten stream, which is thickened and dried as feed.
- Starch washing
A battery of starch hydrocyclones washes the starch with fresh water until protein falls to food or industrial grade.
- Dewatering, drying and bagging
A peeler centrifuge or vacuum filter removes water, a flash dryer brings the starch to bagging moisture, and it is sieved and packed.
Steep water is a product, not just effluent: evaporated steep liquor is sold for fermentation media and feed, which also cuts the load on the effluent plant.
Wet milling or dry milling: which maize processing unit?
"Maize processing" covers two different plants. This page and the sample report model wet milling for starch; dry milling for grits and flour is a lighter, cheaper plant with a different market.
| Point | Wet milling (starch) | Dry milling (grits and flour) |
|---|---|---|
| Main products | Starch, with germ, gluten, fibre and steep liquor | Grits, maize flour and suji, with germ and bran |
| Key step | Steeping for 28 to 48 hours, then separation in water | Tempering and degerming, then roller milling and grading |
| Typical output split | Depends on steeping and separation; every stream is sold | Grits about 70%, flour 10%, fine grits 10%, germ 7%, bran 3% |
| Water and effluent | Large water use; effluent plant and steep water handling needed | Little process water |
| Main buyers | Paper, textile, adhesive, food and pharma users | Corn flakes and snack makers, breweries, flour packers |
Dry milling split from NIFTEM's maize processing write-up for 50 and 100 TPD plants.
Raw materials for maize starch
Maize is 90% of raw material cost in the sample; the rest is steeping and process chemicals, chiefly sulphur dioxide. Starch makes up about 70–74% of the kernel, so grain quality and moisture at purchase decide how much starch each tonne gives.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Maize | 90% | 799.42 |
| Chemicals | 10% | 88.82 |
| Total | 100% | 888.24 |
Year 3 cost at 70% utilisation, from our illustrative sample.
Machinery for a maize starch plant
Separation and drying take the largest shares of machinery cost in the sample, at ₹38.04 lakh each. Most of the wetted equipment is stainless steel, because the steep water is acidic.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Steeping tanks | Soak maize in sulphured water in batches | 22.82 |
| Degerminator and mills | Free the germ, then grind the endosperm fine | 30.43 |
| Separators and hydrocyclones | Split starch from gluten and wash it to grade | 38.04 |
| Starch dryer | Flash dries wet starch to bagging moisture | 38.04 |
| Effluent plant | Treats process water before reuse or discharge | 22.82 |
| Total plant and machinery | 152.15 | |

Market for maize starch in India
India grew 245.41 lakh tonnes of maize in 2024-25 by the first advance estimates, as reported by PJTSAU's market intelligence centre in February 2025. Starch makers compete for that grain with poultry feed and ethanol distilleries, so a unit near a maize belt buys at better prices.
Demand for the starch itself comes from industries that use it as a binder, thickener or sizing agent, and from units that convert it into sweeteners.
- Paper and board mills, for surface sizing and strength
- Textile mills, for warp sizing and finishing
- Corrugated box and adhesive makers
- Food processors and corn flour packers
- Pharmaceutical tablet makers
- Liquid glucose and dextrose units
By-products carry the margin: germ sold to oil mills and gluten and fibre sold to feed makers often decide whether starch at market price covers the maize bill.
Licences and approvals for a maize starch unit
| Business registration | Udyam (MSME) registration and GST registration |
|---|---|
| Food licence | FSSAI licence for edible maize starch, a standardised starch under FSSAI's product standards; the licence tier depends on capacity |
| Product standard | IS 1005:1992, edible maize starch (corn flour), reaffirmed by BIS in 2023 |
| Pollution board consent | Consent to establish and operate; "manufacturing of starch/sago" is in the Orange category in Odisha's list based on CPCB criteria, so check your own state's list |
| Factory and safety | Factory licence where the workforce threshold applies, fire NOC and an industrial power connection |
| Packaged sales | Legal Metrology registration if you sell starch in retail packs |
Mistakes that weaken a maize processing project report
- Assuming the kernel's full starch content
Some starch is lost with fibre, gluten and wash water. A report that converts maize to starch at kernel content overstates output.
- Leaving out by-product sales, or pricing them at retail
Germ, gluten and fibre need their own buyers and realistic ex-factory rates, or the margin is wrong in either direction.
- Under-sizing steam and power
Drying wet starch takes heat and the separators run on power round the clock. Too low a fuel cost leaves cash short after the loan is drawn.
- No plan for steep water and effluent
Wet milling uses a lot of water. Without effluent treatment the pollution board consent can be delayed or refused.
- Ignoring the maize harvest cycle
Buying only at spot price after the harvest raises cost. The working capital limit should allow for stocking maize when it is cheaper.

Maize Starch project report: frequently asked questions
What is the cost of a maize processing plant in India?
It depends mainly on maize grinding capacity and how far you refine the starch. Our sample report models a 20 MT per day maize starch unit at ₹328.80 lakh, including ₹152.15 lakh of plant and machinery and ₹31.66 lakh of working capital margin. Integrated plants that also make liquid glucose or dextrose cost far more, so get a report sized to your own plan.
What products come out of maize processing?
Wet milling splits maize into starch, germ, gluten, fibre and steep water. Starch is the main product. Germ goes to oil mills for maize germ oil, gluten and fibre are sold as cattle and poultry feed, and steep water is used in fermentation media. Dry milling gives grits, maize flour and suji instead, with germ and bran as by-products.
How much starch can you get from maize?
Starch makes up about 70–74% of the maize kernel, but a plant recovers less than that because some starch stays with the fibre, gluten and wash water. Recovery depends on maize quality, steeping time and how well the separators and hydrocyclones are run. A project report should state the yield it assumes and price each by-product separately.
Is a maize starch business profitable?
It can be, if maize is bought well and the by-products are sold. In our illustrative sample, a 20 MT per day unit earns a 28.7% return on investment in Year 3. It breaks even at 36.5% of capacity and has an average DSCR of 2.15. Real margins swing with maize prices, so test a price rise before you commit.
Can I get a PMEGP loan for a maize starch unit?
Only for a small unit. PMEGP covers manufacturing projects up to ₹50 lakh, with a margin money subsidy of 15–35% depending on category and location. A wet milling plant with steeping, separation and drying usually costs more than that, so most units take an MSME term loan with a cash credit limit for maize stock.
Is the sample report free and can I use it for a loan?
Yes, the sample is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report. Its figures are representative rather than from a real project, so do not submit it to a bank. For a loan, NPCS prepares a report for your own capacity, location and lender.
