What is biomass pellet ?

Biomass pellets are fuels made from compressed organic matter or biomass.

Biomass pellets can be made from any one of five general categories of biomass: industrial waste and co-products, food waste,

agricultural residues, energy crops and virgin lumber.

Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust and related industrial

wastes from the milling of lumber, manufacture of wood products and furniture, and construction.

Other industrial waste sources include Empty Fruit Bunches [EFB], palm kernel shells, coconut shells,

and tree tops and branches discarded during logging operations.Pellets are categorized by their heating value,

moisture and ash content, and dimensions. They can be used as fuels for power generation, commercial or residential heating,

and cooking.Pellets are extremely dense and can be produced with a low moisture content (below 10%) that allows them to be burned with a very high combustion efficiency.

Biomass pellets are produced by compressing the material,

which has first passed through a hammer mill to provide a uniform dough-like mass.This mass is fed to a press where it is squeezed through a die having holes of the size

required (normally 6 mm diameter, sometimes 8 mm or larger). The high pressure of the press causes the temperature of the wood to increase greatly, and the ligninplasticizes slightly forming a natural "glue" that holds the pellet together as it cool.
