NOVELTY - Using waste from recovery of cellulose as fuel in the cement industry, being particularly applicable to wastes obtained from pulp recovery processes from waste paper comprising a mixture with composition of 53% cellulosic fibers and 47% calcium carbonate and a humidity of 60-65%, and that can be used as supplementary fuel in a furnace of cement clinker production, involves drying the material to a moisture of less than 10% and extruding in order to maintain its integrity, where drying step uses residual heat from actual cement works.    USE - The method or drying module is useful for using waste from recovery of cellulose as fuel in the cement industry (claimed).    ADVANTAGE - The advantages of the method are: (a) latent heat is recovered from cellulose; (b) calcium carbonate is absorbed in the process; (c) no waste any kind is produced, being fully absorbed and the unburned part of cement clinker, without diminishing any of its final characteristics; (d) the method removes a residue that is difficult to treat; (e) part of the residue of combustion comes from renewable materials (cellulose); (f) the method can produce renewable fuels, such as coal, gas, and natural gas; (g) the method provides environmental benefit by reducing the material extracted from the quarries of the cement factory; (h) the method takes advantage of residual heat remaining in the cement factory; and (i) importantly, the method provides conventional fuel savings, and allows an adequate return.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a drying module for using waste from recovery of cellulose as fuel in the cement industry, comprising a cabinet having hot gas intakes at the top and outlet tubes at the bottom, which comprises conveyor belts at various levels which move the material downwards while keeping same exposed to the influx of the gases, where a weighing belt dispenses the material onto a perforated-plate extruder which transforms the material into small cylinders, depositing same on the conveyor belt located at the top of the cabinet.
