Biomass Briquette OR Bio Coal is made from agricultural, wooden and forestry wastes by high compression process without adding any chemical, glue or binder. It is thus binder-less technology product resulting in 100% natural eco-friendly, pollution-free solid fuel. Biomass briquettes are a renewable source of energy and avoid adding fossil carbon to the atmosphere.

A popular biomass briquette takes a waste produce such as sawdust, groundnut shells, cotton stalk, castor seed shells etc.; compresses it and then extrudes it to make a reconstituted log that can replace firewood and coal. The Calorific Value (GCV) of the bio-coal is3900+ KCal/Kg. Moisture content of a briquette can be as low as 4%, whereas green firewood may be as high as 55%.Biocoal has high density around 1000 Kg/m³ saves transport costs and space in storage.A very low moisture and ash content around 8% makes briquette preferable solid fuel. Due to the vast availability and constant generation of agricultural wastes, supply of briquettes can be easily available through the year with desired quantity.
