ABSTRACT
Pelletization is a technique used to compact biomass, generating a granulated material called
pellets, with high energy density. The objectives of this work were to produce pellets made
from Sorghum (Sorghum bicolor) residuals and to evaluate its quality. Firstly, the residuals were
characterized, followed by the production of the pellets. An experimental framework was adopted,
entirely randomized with three treatments: T1 – 100% Sorghum, T2 – Sorghum + addition of
wheat starch, and T3 – Sorghum with the addition of steam. There was also a comparison of the
properties of the pellets with values determined by the European standard. It was concluded
that Sorghum biomass (Sorghum bicolor) residuals are viable for pellet production; products
obtained were homogenous and easy to handle; the treatment T1 presented the best results for
pellet production; all treatments produced pellets within the specifications of the EN 14961-6
(DIN, 2012) standard for non-wood pellets.
Keywords: pelletization; energy potential; biomass.
