1. Method for the removal of the harmful components from at least one of urban wastes, industrial wastes, and sludges before the thermochemical conversion of the urban wastes, industrial wastes and sludges, the method consisting of the following steps:
prepyrolysis of the wastes, wherein the prepyrolysis of the wastes occurs at temperatures between 200° C. and 320° C., for 5 min to 2 h; and
washing of the prepyrolysis wastes with at least one aqueous solution comprising acetate salt, wherein the washing of the wastes occurs with an aqueous solution selected from the group consisting of calcium acetate, magnesium acetate, aluminum acetate, and combinations thereof at concentrations of 0.5% to 5% weight basis, at a solid-to liquid ratio 33 g/L to 600 g/L, temperature between 13° C. and 95° C., and treatment time from 5 min to 24 h.
