Product Description
Biomass Briquette investment is a best project to generate revenue from agroforestry 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 agroforest 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.
