Abstract
An assembly for processing green biomass materials from two separate feed sources for use as a fuel pellet includes a drying assembly, a torrefaction assembly and a heating assembly. The drying assembly is adapted to convert the green biomass material obtained from a first source to white biomass material. The torrefaction assembly is adapted to convert green biomass material obtained from a second source to torrefied biomass material. The heating assembly provides heat for both the drying assembly and the torrefaction assembly.
