A fuel pellet is produced by the combination of organic waste material with a binder obtained by direct liquefaction and/or fast pyrolysis of biomass material. Direct liquefaction and fast pyrolysis are carried out according to known liquefaction processes. The liquefied bio-binder base is mixed with additives, if desired, such as petroleum asphalt and cross-linking agents, in order to modify its characteristics to meet specific needs of particular applications, and the resulting mixture is mixed with organic-waste material preheated to 100° C. or more and allowed to react at about 150-200° C. Combustible extenders and fillers, reinforcing fibers, and cross-linking agents may be mixed with the organic material or the bio-binder base to provide additional specific properties to the mixture. The resulting well mixed mass is then pelletized or otherwise molded in conventional equipment.
