Briquettes
A briquette is a block of compressed coconut coal dust, charcoal dust, sawdust, wood chips or biomass — used as fuel in stoves and boilers. We supply briquettes for thermal applications across industries.
Types of briquettes we supply
Coconut Charcoal
~80% charcoal content, 7500–8000 kcal/kg, tube-shape design, low ash & smoke.
Saw Dust
Compressed wood-waste briquettes for industrial thermal and heating applications.
Rice Husk
Agro-waste briquettes for steam generation, drying processes and gasification.
Coal Powder
Agglomerated coal-powder briquettes for higher-density industrial fuel needs.
Different briquette types are matched to end-use requirements. Packing options: corrugated carton box, craft bags or PP bags.
Coconut charcoal briquette — key benefits
Reference: ordinary charcoal has a calorific value of ~6,500 kcal/kg. Briquetted charcoal also burns longer than lump wood charcoal.
Thermal applications
Briquettes are widely used for any type of thermal application — steam generation in boilers, heating, drying processes and gasification plants — as a replacement for coal, wood and liquid fuels (FO, Diesel, LDO, Kerosene, etc.).

Coconut Charcoal & Activated Carbon
Coconut shell charcoal is an intermediate product made by carbonising coconut shells. Activated carbon is an inert, porous material used for casting foundries, gas/vapour adsorption and liquid purification.
Grades & demand profile
| Grade | Indicative demand share |
|---|---|
| Coconut Charcoal chips | 30% |
| Powder | 35% |
| Granular pelletised grade | 15% |
| Pharmaceutical grade | 20% |
Pharmaceutical-grade carbon is typically made from pinewood charcoal owing to very low ash and acid-soluble content.
