Pelletization is a technology for upgrading biomass that is seeing rapid global growth due to
low processing costs, low energy requirements for upgrading and high versatility of the
resulting fuel. The energy demand for densifying dry biomass to pellets amounts to about 2%
of the energy content of the resulting fuel.

1 Within the last 25 years global pellet production has increased from around 1 million tons to over 65 million tons. The largest global pellet producer is currently China, with a production exceeding 20 million tons. While wood and forestry residues have been the main source of raw material for pellet production up until now, increasing attention is currently going towards utilizing agricultural residues as raw materials.
