The current price of raw materials (sawdust, wood chips and wood shavings) for wood pellet production is about 60~80 usd/t. But raw materials need to remove the moisture content, usually 20~60%, to 8%. Let's take the moisture content as 40%. Therefore, the cost for raw materials for 1 ton is about 88~117usd/t.

The Process of Torrefaction. Heating (200-300o C) wood, in a low-oxygen environment, liberates water, volatile organic compounds (VOC's), and hemicellulose (HC) from the cellulose and lignin. The VOC's and HC are combusted to generate 80% of the torrefaction process heat. The remaining and warm lignin acts as a binder when the torrefied ...
