PROBLEM TO BE SOLVED: To provide defibrated waste paper used as a reinforcing material for resin or cement and obtained by removing pieces of paper having the possibility of causing strength degradation.SOLUTION: There are provided a method for producing defibrated waste paper obtained by removing pieces of paper, and defibrated waste paper obtained by removing pieces of paper by the method. The method can continuously operate a step of removing pieces of paper from defibrated waste paper by: drying and defibrating waste paper by a defibration machine and then making the waste paper pass through a screen having a prescribed opening equipped with a rotary airbrush capable of removing clogging by an air flow; or drying and defibrating waste paper by the defibration machine and then making the waste paper pass through the screen having the prescribed opening equipped with the rotary airbrush capable of removing clogging by an air flow and then continuously making the waste paper pass through a screen having a prescribed opening smaller than that of the above-mentioned screen, the screen being equipped with the rotary airbrush capable of removing clogging. |
