International Classification:

C10L 5/48

US Classification:

44589

Abstract:

A method for manufacturing solid fuel, including estimating a heat value for at least a portion of a combustible waste stream. At least one type of combustible polymer is added to the combustible waste stream as needed to raise the estimated heat value of the portion of combustible waste stream to a desired heat value. The combustible waste stream is heated and mixed while adding a binder to the combustible waste stream to increase the structural integrity of a solid fuel formed from the mixed combustible waste stream. The heated and mixed combustible waste stream is pressed into briquettes of solid fuel which are substantially hydrophobic.
