“Glass Cullet” Generation Technique by Underwater Shockwave for Recycling System of Glass Bottles
The high-speed fracture mechanics of glass bottles by using underwater shockwaves technique and its application for recycling system of glass bottles were discussed. The proposed small fragments, also called “Cullet”, generation technique can decrease the recycling cost by carrying out of crashing and cleaning process simultaneously. In this study, the effects of the explosive conditions and multi-specimen’s arrangements on the “Cullet” sizes were investigated and basic data for commercialization of this method were obtained. An FEM simulation and framing photograph were used to observe underwater shock wave and fracture propagation.
