Gujarat has over 3,500 registered brick kilns (bhathas) concentrated in Ahmedabad, Mehsana, Gandhinagar, and Surat districts. These kilns consume enormous quantities of coal and firewood — and are under increasing scrutiny from the Gujarat Pollution Control Board (GPCB) for air quality violations. Biomass pellets are emerging as the most practical, cost-effective alternative.
Why Brick Kilns Are Under Pressure
Traditional Fixed Chimney Bull's Trench Kilns (FCBTK) and Zigzag kilns in Gujarat currently burn 15–25 MT of coal per lakh bricks. With Indian coal prices at ₹11–₹14/kg, fuel alone costs ₹1.65–₹3.50 lakh per lakh bricks. Add to this growing GPCB notices for particulate matter (PM10/PM2.5) violations and seasonal ban enforcement, and kiln operators face a genuine operational crisis.
How Biomass Pellets Solve the Problem
BBI's high-GCV biomass pellets (4200–4600 Kcal/kg) are a proven drop-in fuel for zigzag brick kilns. The combustion characteristics of pellets — dense, uniform cylinder shape, low moisture, low ash — make them highly suitable for the kiln firing tunnel.
- Uniform heat distribution: Pellets burn more evenly than coal lumps, reducing over-fired and under-fired brick rejection rates by 15–20%.
- Smoke reduction: <2% ash and <10% moisture produces significantly less particulate smoke vs coal, helping kilns pass GPCB stack emission tests.
- Firewood replacement: For kilns using firewood for initial firing, pellets provide equivalent ignition energy at lower cost and with far less smoke.
Cost Calculation for Brick Kiln Operators
| Parameter | Coal | BBI Biomass Pellets |
|---|---|---|
| Cost per kg | ₹11–₹14 | ₹9–₹11 (bulk) |
| GCV (Kcal/kg) | 3800–4200 | 4200–4600 |
| Ash content | 25–35% | <2% |
| GPCB compliance risk | High | Low |
| Fuel per lakh bricks | 18–22 MT | 16–19 MT (less fuel needed) |
Getting Started
Most Gujarat brick kiln operators can transition within one firing cycle. BBI supplies biomass pellets ex-factory from Bakrol, Ahmedabad — conveniently located within 50–100 km of most major kiln clusters in central and north Gujarat.
