BIOMASS FUEL COMPACT PROCESSING METHOD
A method of processing a biomass fuel compact is provided by the present disclosure that includes comprising combining a composition of combustible biomass materials, comminuting the composition of biomass materials, drying the comminuted composition of biomass materials, and adding an adhesive to the biomass materials, the adhesive comprising a starch and a hydroxide. Further additives are also provided, which include a silicate, a viscosity agent, a preservative, and a BTU additive. The composite biomass is processed into a shapeform, and then the shapeform is partitioned into individual pieces that are compatible with existing powerplants. In one form, the processing is performed at lower temperatures such that an endothermic reaction of the biomass materials and adhesive results.
