Pellet production

Graanul Invest has developed rapidly and grown to be Europe´s biggest pellet producer.

Graanul Invest Group includes 12 modern pellet factories - 4 in Estonia, 6 in latvia, one in Lithuania and one in USA. 

The main product of  AS Graanul Invest is pellets produced from softwood sawdust and wood chips. Group production capacity is 2,7 million tons per year.

Pellets constitute a solid biological fuel, being one of the most convenient and effective sources of renewable energy.

This process results in the production of pellets with the diameter of 6 – 8 mm. Pellets do not contain any additives besides natural wood. Pellets due to uniform quality and dimensions  can be conveniently used in automatic household heating solutions as well as in automated industrial systems.
