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 55mm.

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
