To set up a kraft paper mill you need five things: a feasibility study, a site with reliable power and water, the right machinery (a pulping or waste-paper line, a paper machine and an ETP), regulatory clearances, and trained operators. Rajshree Group supplies complete turnkey kraft paper mills from 10 to 300 TPD — design, manufacturing, installation and commissioning — across India, Africa and the Middle East since 2003.
In 2021 we supplied and commissioned a complete 100 TPD kraft pulp mill in Gorakhpur, Uttar Pradesh — wood yard, digester, brown-stock washing, bleaching and pulp dryer. Since 2003, Rajshree Group has delivered 22+ pulp and paper projects across three continents — India, Africa and the Middle East — totalling over 2,000 TPD of installed capacity.
India's packaging paper market consumes over 8 million tonnes per year, growing at 8–10% annually on the back of e-commerce, FMCG, and export packaging demand. A well-planned 30–100 TPD kraft paper mill can achieve payback in 4–6 years at current OCC prices and kraft paper realisations. Yet a significant number of paper mill projects in India stall or underperform because investors focus only on the paper machine price — ignoring the 12 other decisions that determine whether the project succeeds. This guide covers every phase from first feasibility to first saleable paper.
Phase 1: Feasibility Study and Market Analysis
Before committing capital, a rigorous feasibility study determines whether the project is viable at the target location, scale, and product mix. This is not a document you commission after deciding to build — it is the decision-making tool that tells you whether to build and at what scale.
The study must cover: OCC (Old Corrugated Carton) availability and pricing within 200 km radius, target product mix and local buyer landscape, land and utility cost at shortlisted sites, capex and opex estimation, and a 10-year financial model with sensitivity analysis on OCC price and kraft paper realisation. For a 50 TPD plant in India, indicative total project cost ranges from INR 40–60 crore depending on machine width, speed, and civil scope.
Before finalising any site, verify that monthly OCC availability within 200 km covers at least 110% of your projected raw material requirement. Raw material security is the single biggest risk variable in a kraft paper mill business plan — more important than the paper machine specification.
- Market demand: local packaging converters, corrugation plants, buyers in 300 km radius
- OCC supply audit: volumes, pricing, aggregator network, seasonality
- Site evaluation: power, water, road connectivity, land cost
- Capex estimate: machinery, civil, utilities, ETP, working capital
- Financial model: revenue, margins, IRR, payback — with sensitivity analysis
Phase 2: Site Selection and Land Acquisition
A 50 TPD kraft paper mill requires 1.5–3 acres of industrial land including the machine building, OCC storage yard, finished goods warehouse, ETP, and utilities. Industrial zones with existing infrastructure — 33 kV or 66 kV grid connection, industrial water supply, and paved access roads — dramatically reduce utility capex and project timeline versus a greenfield rural site.
The single most common site selection mistake is optimising for low land cost at the expense of power and logistics. Every kilometre of HT line extension to reach the site adds INR 15–25 lakh in electrical capex. A site 10 km from the grid that saves INR 50 lakh on land acquisition may cost INR 2 crore more in HT line extension and substation — a decision that is irreversible once the land is purchased.
Rank sites in this order: (1) power availability — 33 kV substation within 2 km, (2) OCC logistics — highway access to major supply centres, (3) water — borewell yield or municipal industrial supply, (4) land cost. Most investors reverse this order and regret it.
- Minimum 1.5 acres for 50 TPD; 3+ acres for 100 TPD including ETP and storage
- Power: 33 kV or 66 kV grid within 2 km; 2 MVA for 50 TPD, 4 MVA for 100 TPD
- Water: 10–20 kL per tonne of paper produced — borewell yield or industrial connection
- Road: NH or SH frontage preferred for heavy OCC truck access
- Pollution board: check receiving water body status before committing to site
Phase 3: Machinery Selection and Procurement
The paper machine is a 25-year asset. Its specification — machine width, design speed, forming section type, press configuration, and automation level — locks in your production capacity, paper quality ceiling, and maintenance cost for the life of the mill. Getting this decision right requires understanding not just what the machine costs today but what it will produce and cost to run for the next two decades.
For a 50 TPD kraft paper mill using OCC, a multi-cylinder (vat) machine at 2.8–3.2 m trim width is the standard configuration in India's small and mid-scale sector. It offers lower capex than a Fourdrinier at equivalent capacity, simpler operation, and proven performance on OCC furnish at 80–300 GSM. A Fourdrinier is the right choice if your target grade requires tighter basis weight uniformity or if you plan to produce lighter kraft grades below 80 GSM.
Rajshree supplies complete matched machinery packages — stock preparation, paper machine, winder, and utilities — all specified to work at the same design capacity. This eliminates the bottleneck problems that occur when mills source each section from different vendors with mismatched throughput ratings.
| Capacity | Machine Type | Machinery Capex | Total Project Cost |
|---|---|---|---|
| 30 TPD | Multi-cylinder, 2.4 m trim | INR 8–14 crore | INR 20–35 crore |
| 50 TPD | Multi-cylinder, 2.8 m trim | INR 14–22 crore | INR 40–60 crore |
| 75 TPD | Fourdrinier, 3.2 m trim | INR 22–35 crore | INR 60–90 crore |
| 100 TPD | Fourdrinier, 3.6 m trim | INR 32–50 crore | INR 75–120 crore |

The paper machine building for a 50 TPD plant is typically 80–100 m long, 18–22 m wide, with a clear height of 8–10 m for crane access. The machine raft foundation — isolated from the main building structure — must be designed for the machine weight and vibration load by a structural engineer who understands paper machine dynamics. Foundation errors discovered after machine installation are extremely costly to correct.

Phase 5: ETP Design and Environmental Compliance
A kraft paper mill using OCC generates 15–35 m³ of wastewater per tonne of paper produced, with COD of 1,500–3,000 mg/L before treatment. CPCB standards require discharge at COD below 250 mg/L and TSS below 50 mg/L. A properly designed three-stage ETP — primary (clarifier + DAF), secondary (aeration tank + secondary clarifier), and tertiary (polishing filter) — is mandatory for all mills above 10 TPD and must be operational before Consent to Operate is granted.
ETP design is frequently underbudgeted in paper mill projects. The most common mistake is sizing the ETP for average flow rather than peak flow — a mill running above design throughput during good market conditions generates 30–40% more effluent than the ETP was sized for, causing compliance problems precisely when the mill is most profitable. Rajshree designs all ETP systems with a 25% flow buffer above contracted machine capacity.
Primary ETP sludge from an OCC-based kraft mill contains 40–60% fibre that can be recycled back to the pulper — reducing both sludge disposal cost and fresh OCC consumption by 3–5%. Design the sludge handling system to enable this recycling loop from day one.
Phase 6: Financial Returns — What to Realistically Expect
At 50 TPD and 85% utilisation (15,500 TPY), with kraft paper realisation of INR 40/kg, annual revenue is approximately INR 62 crore. With OCC at INR 14/kg and total variable cost of INR 30/kg, gross profit is INR 10/kg — INR 15.5 crore/year. After fixed costs (depreciation, interest, overhead) of INR 7–9 crore, net profit is INR 6–8.5 crore/year on a INR 50 crore project — payback of 6–8 years on net profit basis, 3–4 years on EBITDA basis.
OCC price is the dominant margin variable in a kraft paper mill. Every INR 1/kg movement in OCC price changes annual profit by approximately INR 1.5 crore at 50 TPD scale. Mills that lock in OCC supply through annual contracts with large aggregators achieve 30–40% better margin stability than those buying spot — this procurement decision is as important as the machinery specification.
