Product Description

Biomass Briquette investment is a best project to generate revenue from agro-forestry waste and to produce Green Energy to protect the global environment. The awareness of using Eco-friendly & Non-conventional Bio-coal / Bio-fuel is increasing day-to-day due to the increasing of the conventional fuel cost.

This Complete Charcoal Briquette Machine can make stick shape wood briquette of different diameter and different shape from biomass and agro-forest waste. Any type of Agro-Forestry waste can be used, such as Groundnut-shell, Sugarcane residue, Saw dust, Coffee Husk, Paddy Straw, Sunflower Stalk, Cotton Stalks, Tobacco waste Mustard Stalk, Jute waste, Bamboo Dust, Tea waste, Wheat Straw, Palm husk, Soybeans husk, Rice Husks, Forestry wastes, Wood Chips and many other Agro wastes. But the Moisture Content Should be Less than 12%, grain size is below 5*5mm.

Briquettes do not take up a great deal of space. Densified biomass fule are efficient in storing, although coal oil require even less space, see table 3.4.
