The goal is to obtain a solid biofuel, including Ligna from cattle, goat and pig manure, which meets the energy and environmental standards of ISO 17225-6 and an access method. This method is mainly based on the separation of pollutants and artemisinin. This is done by feeding the system into a washing tank to process the manure in the tank； by rotating, ultrasonic and water trawling to wash the manure in the tank； and by adding a continuous clean water flow in the tank.Liquid and solid separation, using compressor to remove excess water from Solid biofuels, without drying, and finally drying. Although there are similar processes for obtaining biofuels from fertilizers, the new situation is that this process is not combined with other products, such as reed or straw； it is not necessary to incorporate chemical processes, nor to go through high temperature or carbonization processes. This biofuelIt may not be compressed or powdered for your sale. Since ancient times, livestock manure has been used as a source of fuel for human beings. However, the accumulation and burning bring a series of disadvantages and dangers to human health, including the stench caused by decay, the corrosive substances produced, the toxic gases produced during combustion, as well as the material stains and stains on the exterior walls and interior 9. Housing and buildings.El objetivo es la obtencion de un biocombustible solido que comprende lignina proveniente del estiercol de ganado bovino, caprino y porcino que cumple con la norma ISO 17225-6 tanto en materia energetica como ambiental y un metodo para su obtencion. El metodo se basa principalmente en la separacion de los contaminantes de la lignina. Esto se logra por los siguientes pasos: tratamiento del estiercol en estanque de lavado por medio de alimentacion del sistema hacia un estanque de lavado； lavado del estiercol en el estanque de lavado por medio de movimientos rotatorios y ultrasonido y arrastre por agua； adicion de un flujo cont
