Biomass Briquette Plant Setup: Raw Material, Machinery and Planning
Last updated: 1 November 2026 · By KSR Green Bharat Team
Quick answer: A biomass briquette plant converts agro or wood residue into dense fuel blocks using a crusher, a dryer (when feedstock is wet) and a briquetting press, plus conveyors and covered storage. To set one up, secure year-round feedstock, line up industrial boiler or kiln buyers, choose the press type that suits your material and output, plan generous covered storage, and obtain pollution, factory and fire approvals. Feedstock reliability and moisture control matter more than the press itself.
Key takeaways
- Briquettes suit nearby industrial boilers, furnaces and kilns.
- Most presses need no binder when moisture and particle size are right.
- Storage for seasonal residue is usually the most underestimated cost.
- Agree specifications with buyers before buying machinery.
Is a briquette plant right for your project?
If you are still deciding between fuel forms, start with our pellets vs briquettes comparison. In short, briquettes are a strong fit when your buyers are within a reasonable truck distance and fire their boilers on grates rather than pulverised fuel.
Which raw materials can be briquetted?
| Feedstock | Notes |
|---|---|
| Groundnut shells | Popular, good binding; seasonal in groundnut-growing areas |
| Mustard stalks and husk | Widely available in Rajasthan and Haryana after the rabi harvest |
| Soybean husk and residue | Available in soybean-growing belts including the Hadoti region |
| Cotton stalks | Woody; needs strong chopping and crushing |
| Sawdust and wood waste | Consistent and low ash, but competing demand can raise prices |
| Rice husk and paddy straw | High silica and ash; abrasive on wear parts |
Mixing residues can smooth seasonal gaps, but each blend should be tested for moisture, ash and calorific value.
What is the briquetting process?
- Receiving and sorting: remove stones, soil, metal and plastic.
- Size reduction: chop and crush to the particle size your press needs.
- Drying: bring moisture to the press’s working range – commonly around 8–12% for high-pressure briquetting.
- Briquetting: a press compresses material through a die; heat from friction and pressure binds it.
- Cooling and storage: let briquettes cool and harden before stacking under cover.
- Dispatch: loose or bagged, according to buyer preference.
Which briquetting press should you choose?
| Press type | How it works | Typical fit |
|---|---|---|
| Mechanical piston (ram) press | A reciprocating ram pushes material through a tapered die | Higher outputs, solid briquettes, common in Indian plants |
| Screw extruder | A rotating screw forces material through a heated die, often producing a hollow log | Good combustion; higher wear and power use |
| Hydraulic press | Hydraulic cylinder compresses material | Lower outputs, more tolerant of variable material, quieter |
Ask suppliers for output figures on your actual feedstock and visit an operating installation. Check die and ram or screw life, availability of spares, and the power rating per tonne.
How should you plan the layout?
- Raw material yard: open storage for bales and loose residue, with drainage.
- Covered raw material shed: for dried material ready for processing.
- Process shed: crusher, dryer, conveyors and presses with space for maintenance access.
- Finished goods shed: dry, ventilated storage away from heat sources.
- Fire safety: separation distances, hydrants or extinguishers, and clear access for fire tenders.
Who buys briquettes and what do they check?
Typical buyers include boilers in textile processing, dairies, food processing, pharmaceuticals and chemicals, as well as brick kilns and foundries. They usually specify minimum calorific value, maximum moisture and ash, size, and delivery frequency. Agree these in writing and test every lot before dispatch. Our biomass fuel supply guide explains how industrial buyers evaluate offers.
What approvals are needed?
- Udyam and GST registration
- State Pollution Control Board consent, as applicable
- Factory licence and local trade licence
- Fire NOC
- Electricity connection for the connected load
In Rajasthan, the Rajasthan Biomass and Waste to Energy Policy, 2023 promotes briquette and pellet units and states that no registration charges apply to their registration under the policy. Confirm current procedures with RREC. For central support, see our 2026 subsidy status guide.
Common mistakes in briquette projects
- Buying a press rated on sawdust and running it on straw or husk.
- Skipping a dryer and losing quality during humid months.
- Not budgeting for wear parts and spare dies.
- Selling to one buyer only, with no backup outlet.

Frequently asked questions
What raw materials are used in a briquette plant?
Groundnut shells, mustard stalks and husk, soybean husk, cotton stalks, sawdust, rice husk, coffee husk, bagasse and many other agro and wood residues can be briquetted. Choose based on year-round local availability and test results, not price alone.
Do biomass briquettes need a binder?
Most mechanical piston and screw presses rely on heat and pressure to activate the natural lignin in biomass, so no binder is needed when moisture and particle size are controlled. Low-pressure processes may use binders.
What moisture is required for briquetting?
Feedstock is typically prepared to around 8 to 12 percent moisture for high-pressure briquetting. Too wet and briquettes crack or swell; too dry and they may not bind well.
Who buys biomass briquettes?
Typical buyers include industrial boilers in textiles, food processing, dairies, pharmaceuticals and chemicals, as well as brick kilns, foundries and commercial kitchens. Agree on calorific value, ash, moisture and size with the buyer before production.
How much space does a briquette plant need?
Beyond the machinery shed, the biggest requirement is covered and open storage for seasonal feedstock and finished stock. Plan storage for at least several weeks of operation, especially across the monsoon.
