Biomass Pellet Plant Setup in India: A Practical 2026 Guide

Last updated: 1 November 2026 · By KSR Green Bharat Team

Key takeaways

• Start with the buyer and the feedstock, then size the machinery around them.
• Demand is policy-backed: coal-based thermal power plants must co-fire at least 5% biomass pellets or torrefied MSW charcoal from FY 2025-26 (7% in Delhi-NCR).
• Power plant buyers test every consignment for moisture, calorific value, fines and size, so quality control is part of plant design.
• Project cost varies far more with land, dryer, storage and grid connection than with the pellet mill price.

Why are biomass pellet plants in demand in India?

Three forces are driving new pellet capacity. First, the Ministry of Power’s comprehensive co-firing policy, notified in November 2025, requires all coal-based thermal power plants to co-fire a minimum of 5% biomass pellets or torrefied MSW charcoal by weight from FY 2025-26, with plants in the Delhi-NCR required to reach 7%. Second, industries running boilers are replacing part of their coal with biomass to cut fuel cost volatility and emissions. Third, crop residue that is otherwise burned in fields is available in large volumes across Rajasthan, Punjab, Haryana, Uttar Pradesh and Madhya Pradesh.

For a detailed look at what power plants require, see our guide to co-firing pellet specifications.

Step 1: Who will buy your pellets?

Before you shortlist machines, decide which buyer segment you are building for, because each one sets different specifications and terms:

Get a written specification, and ideally a trial order or letter of intent, from at least one buyer before ordering equipment.

Step 2: How do you secure feedstock for the whole year?

Feedstock is the single largest operating cost and the most common reason pellet plants run below capacity. Crop residues such as paddy straw, mustard stalks and cotton stalks arrive in short harvest windows, while rice husk and sawdust are steadier but have competing buyers.

• Map sources within an economical radius: volumes, harvest months, current buyers and moisture at collection.
• Test before you design: send samples of each residue to a lab for moisture, ash, calorific value and bulk density.
• Agree supply in writing with aggregators or farmer groups before the season, including baling or collection arrangements.
• Plan storage: straw-based plants need enough covered and open storage to run through months when fresh residue is not available.

In the Hadoti region around Kota, crops such as soybean, mustard, wheat and paddy are widely grown, so a plant here should evaluate a mix of residues rather than depending on one.

Step 3: What is the pellet manufacturing process?

1. Receiving and inspection: weigh and inspect loads; reject wet or contaminated material.
2. Size reduction: shred or chop stalks and bales, then grind in a hammer mill to a fine, uniform particle size.
3. Drying: bring moisture down to the range your pellet mill and feedstock need, typically around 10–15% at the mill inlet.
4. Conditioning and pelletising: the pellet mill presses material through a ring or flat die; heat and pressure activate the biomass’s natural lignin, which binds the pellet.
5. Cooling: a counter-flow cooler hardens pellets and removes surface moisture.
6. Screening: fines are removed and returned to the process.
7. Storage and dispatch: bulk or bagged, always kept dry.

Step 4: Which machinery does a pellet plant need?

Visit an operating plant that runs the supplier’s equipment on a similar residue before you sign. Rated capacity is often quoted for easy materials and can drop significantly on straw or husk.

How much does a biomass pellet plant cost?

There is no single reliable figure. Published estimates range from tens of lakhs for a small machinery line to several crore for a complete project including land, civil work, sheds, dryer, storage and working capital. The items that swing the budget most are:

• Land and civil work, including covered storage sized for the off-season
• Dryer type and its heat source
• Power connection and transformer for the connected load
• Baling and transport arrangements for straw-based feedstock
• Working capital to buy residue during harvest for use months later

A bankable detailed project report built on your own quotations and feedstock prices is essential for financing. Government support has also changed recently; see our 2026 guide to pellet plant subsidy status before you assume any grant in your model.

What approvals and registrations are needed?

• Udyam (MSME) and GST registration
• Consent to Establish and Consent to Operate from the State Pollution Control Board, unless the board confirms in writing that it is not required
• Factory licence and local trade licence
• Fire NOC – start early, because fine dry biomass dust is a real fire hazard
• Electricity connection approvals

Requirements differ by state and district, so confirm the list locally before construction.

Common mistakes to avoid

• Ordering machinery before securing feedstock and a buyer.
• Under-sizing covered storage, especially for the monsoon.
• Choosing a dryer without calculating fuel use per tonne of water removed.
• Skipping lab tests and discovering high ash or low calorific value after commissioning.
• Planning maintenance as an afterthought. Our pellet plant maintenance checklist covers what to plan from day one.

How KSR Green Bharat can help

KSR Green Bharat, based in Kota, Rajasthan, supports pellet and briquette projects from the first site discussion through feedstock and equipment planning, installation coordination, commissioning support and ongoing operations and maintenance. If you are evaluating a pellet plant, share your location, available feedstock, target capacity and project stage, and our team can help you work out a practical scope.

Frequently asked questions

What is the minimum practical size for a biomass pellet plant in India?

For supplying power plants or large industrial buyers, most developers start at 1 to 2 tonnes per hour (TPH). 1 MTPH was also the minimum plant size for MNRE’s Central Financial Assistance under Phase I of the Biomass Programme. Smaller units can work for local boiler or kitchen-fuel buyers, but margins are tighter.

How much does a biomass pellet plant cost in India?

Published estimates vary widely because land, civil work, dryer type, storage and grid connection differ by site. Machinery for a 1 TPH line is often quoted in the tens of lakhs, while a full project with land, sheds, dryer and working capital can run into several crore. Treat any single number with caution and build a site-specific project report from real quotations.

Which raw materials can be used to make biomass pellets?

Common feedstocks include paddy straw, mustard stalks and husk, cotton stalks, soybean residue, rice husk, groundnut shells and sawdust. Power plant buyers usually require agro-residue as the base material and do not accept wood cut from trees. Each feedstock should be lab-tested for moisture, ash and calorific value before you finalise machinery.

What moisture is needed before pelletising?

Biomass is typically dried to roughly 10 to 15 percent moisture before it enters the pellet mill, depending on feedstock and die design. Finished pellets for power plants must not exceed 14 percent moisture as received, under the SAMARTH recommended specification.

What approvals does a pellet plant need?

Typically Udyam and GST registration, consent from the State Pollution Control Board, a factory licence, local trade licence and a fire NOC. Requirements differ by state and district, so confirm the list with the local authorities before construction.
