ABSTRACT:
An improved pelletized fuel consisting essentially of from about 70% to about 98% coal fines and from about 2% to about 30% waste thermoplastic polymeric material (plastic) and a method of producing the improved pelletized fines are disclosed. The plastic is shredded or granulated before mixing with the coal fines, and the mixture is heated to a temperature to soften or melt at least a major portion of the plastic. The heated mixture is then shaped by applying a pressure of at least about 600 PSI and pressing the mixture through a pelletizing or extrusion die, or shaping the mixture in a briquetting operation.
