The system and method of processing a used wind turbine blade provides for processing of a blade at the site of the windmill rather than transporting the blade to a processing facility. The blade may be held stationary while a cutter, such as a drum or plate with cutting teeth, is moved along a portion of the blade to shred the blade. This shredding may occur within a cutting chamber. The blade may be fed into the cutting chamber with a feeder. Smaller particles may be removed or filtered from the air within the cutting chamber and larger particles may be removed and collected in a receptacle. Portions of or the entire system may be made mobile by mounting or otherwise connecting the system to a mobile support, such as a trailer.
