The present invention discloses a method for safely and easily shredding a variety of material particularly material having a low melt temperature and/or containing material sensitive to high static electric charges, such as 1.1 and 1.3 class material. The method comprises applying a cloud of gas vapor onto the shredding means to cool the shredding means to a temperature below that of the melt temperature of the material being shredded and to also reduce the static electric charge on the resulting particles of material which may develop during the shredding process. Further described is an apparatus for carrying out the method.
