An explosive can cause a huge fracture of energy at low doses. A small 'cullet' was generated by using this energy to crush a glass bottle, and the recycling efficiency improvement was examined. Up to now, the influence of the cullet sizes against the amount of explosive, the distance from the explosive to the glass bottles and the bottle arrangement have been studied. During this time, the fracture phenomenon of the glass bottle by an underwater shockwave has been analysed with a high-speed camera and FEM simulation. Keywords: glass-recycle, cullet, underwater shockwave, high-speed fracture， FEM simulation.
