The objective is to obtain a Solid Biofuel which includes lignin from the estiércol Cattle,Goats and pigs which complies with ISO 17225 - 6 in both Environmental and Energy as a method to obtain.The method is mainly based on the separation of pollutants from lignin.This is achieved by the following steps: Treatment of estiércol washing Pond through the system Towards a Pond without washing； washing estiércol in the PondVado via rotational movements and Ultrasound and drag by water； addition of a continuous Flow of Clean Water inside the washing Pond； separation of liquid and solid； PAThe removal of excess water from the solid Biofuel without Drying and finally Drying the same.Although there are similar processes with the aim of achieving a Biofuel from estiércol,The novelty is that is not combined with other products such as Sawdust or Straw； nor is there any need to incorporate chemical processes,Nor is subjected to processes térmicos or carbonización biofuel. This also may or may not be Compacted pelleted for marketing.The Livestock manure has been used as a fuel source by mankind since ancient times.Manure accumulation and burning, however, has a number of disadvantages and hazards to human health, including odor derived from decomposition, bad smell,Generation of corrosive and toxic gases when burned, along with generating substances stained and dirty facades and Interiors of buildings.El objetivo es la obtención de un biocombustible sólido que comprende lignina proveniente del estiércol de ganado bovino, caprino y porcino que cumple con la norma ISO 17225-6 tanto en materia energética como ambiental y un método para su obtención. El método se basa principalmente en la separación de los contaminantes de la lignina. Esto se logra por los siguientes pasos: tratamiento del estiércol en estanque de lavado por medio de alimentación del sistema hacia un estanque de lavado； lavado del estiércol en el estanque de lavado por medio de movimientos rotatori
