Biomass Briquettes (White Coal)
Compressed biomass briquettes (90mm diameter), commonly known as white coal in India, manufactured from agricultural waste in Ahmedabad, Gujarat. Cost-effective coal alternative for small-to-medium industrial furnaces, brick kilns, and manual-fired boiler systems.
What are biomass briquettes (white coal)?
Biomass briquettes, widely referred to as "white coal" in industrial markets across Gujarat, are large-diameter (90mm) compressed fuel blocks made from dry agricultural residues such as cotton stalks, groundnut shells, sawdust, and mustard husk. Unlike automated micro-pellets, white coal briquettes are engineered for manual-fed industrial boilers, downdraft kilns, and brick manufacturing chambers. They offer 3800–4200 Kcal/kg GCV with low ash content (under 4%), making them a highly economical and clean replacement for black coal. Bharat Bio Industries manufactures these briquettes at our facility in Bakrol, Ahmedabad.

Briquettes vs Pellets — When to Choose What?
Briquettes are ideal when your furnace accepts larger fuel pieces and doesn't require automated pellet feeding systems. They burn longer per unit, are easier to handle manually, and cost less per kg. However, for automated boiler systems and co-firing applications, pellets are the preferred choice due to their uniform size and higher GCV.
Brick Kiln & Industrial Furnace Compatibility
BBI biomass briquettes (white coal) are highly recommended for Hoffman brick kilns, downdraft chambers, refractory ovens, and traditional horizontal-grate boilers. The 90mm diameter ensures a slower, controlled release of thermal energy, preventing sudden temperature spikes. This makes white coal briquettes ideal for manufacturing clay bricks, vitrified tiles, and ceramic products in industrial hubs like Morbi and Rajkot, where stable, long-lasting heat is essential.
White Coal Briquettes — FAQ
What is white coal / biomass briquette?
White coal is a compressed 90mm biomass briquette made from agricultural waste. GCV 3800–4200 Kcal/kg with <4% ash — a cleaner, cheaper coal alternative for kilns and furnaces.
What is the price per ton of white coal in Gujarat?
₹6,000–₹14,000 per MT ex-factory Ahmedabad. Final pricing depends on volume, location, and contract terms. MOQ 25 MT.
Are these suitable for Morbi ceramic kilns?
Yes. The 90mm diameter provides slow, stable thermal release ideal for vitrified tile and ceramic manufacturing in Morbi.
Pellets vs briquettes — which to choose?
Briquettes for manual-fed kilns and grate boilers. Pellets for automated boiler feeders and co-firing. Briquettes cost less; pellets have higher GCV and uniformity.
What is the MOQ?
25 MT ex-factory Bakrol, Ahmedabad. Bulk supply contracts from 50 MT/month available.
What is the ash content?
Less than 4%, far lower than Indian coal (25–45% ash). This means less slag, less cleaning downtime, and cleaner combustion stack emissions.
