Observation of High Speed Glass Bottle Fracture Behaviors by Underwater Shockwave

This paper described new effective glass bottle fracture process for glass recycling by underwater shockwave. The high-speed fracture behaviors of glass bottles by explosive energy were discussed. In the proposed technique, the washing process can be skipped because the bottle crushing process execute in water. As a result, the recycling cost can be decreased. In order to clarify the behaviors of glass bottle fracture, the bottle was painted by 5 colors. The crushing experiment was executed under four explosive conditions. The influence of various explosive conditions on the cullet sizes were calcified by using painted bottle.

As the application technique for glass bottle’s recycling system, a new “Cullet” generation method by using underwater shock wave was proposed. This small fragmentation technique of glass bottles has a lot of excellent advantages such as the simplification of process by simultaneous cleaning and crushing operation, the high collect rate of “Cullet” and so on. In this study, the relation between of the explosive conditions and “Cullet” sizes were clarified and the high speed fracture process of glass bottle was observed by framing photograph of high speed image converter.

Aluminum Cans

Recently, many countries are promoting the collection, the reproduction and the use of consumer goods；aluminum cans, PET bottles, and so on. On the other hand, the reproduction of the glass bottles is not so active excluding use as a returnable bottle, because the recycle cost is high. The glass bottles are fractured by the small fragment for reproduction. The small crushing fragments are called ‘Cullet’. The cullet is melted and molded again as glassware. The surface area is enlarged by making the bottle cullet, and it is possible to melt these efficiently. As a result, it becomes possible to shorten the time to melt the glass bottle and reduce a consumption of the fuel oil. The reasons with not active recycling of the glass bottle are that large-scale crushing equipment is required and it takes a lot of time and cost. This study proposed a new recycling technique for fracturing the glass bottle by using an underwater shockwave by explosive and electric pulse. The shock wave pressures produced by the explosive and the electric pulse energy were measured and the optimum crushing conditions were discussed.

Over Time

Humanity has developed recycling activities over time due to their benefits, the shortage of raw materials, or the footprint with regard to the environment. The absence of a recycling culture in Mexico has not allowed its development and growth despite the benefits. In 2012, Mexico only recycled less than 10% of urban solid waste. Most recycling activities are focused on plastic, paper, and cardboard products due to their prices in local markets. This article presents a semi-automated prototype focused on recycling glass bottles using the thermal shock phenomenon. It aims to develop a sustainable glass recycling culture by creating a new branch for the integral glass recycling process and a proposal base on Integrated Sustainable Waste Management (ISWM) and the Quintuple Helix Model. It helps to reduce waste and resource recovery from recycling and upcycling glass bottles. The products obtained from upcycling fulfill new uses and acquire new value, while glass leftovers continue the integral recycling process for glass. Additionally, this paper demonstrates the relation between the ISWM and the Quintuple Helix Model and the opportunity to implement the twelfth Sustainable Development Goal (SDG).

The high-speed fracture mechanism of glass bottles by using underwater shockwave and the recycling process by crushing the glass bottles were discussed. The proposed crushing process of the glass bottles can decrease the recycle cost by generating small fragments called "Cullet" and by executing the washing process at the same time as the crushing process. In this study, the relations between the "Cullet" sizes and various explosive conditions, that is, the distance from explosive, the amount, the velocity and the shapes of explosive, were clarified by using beer bottles, and the influence of the serial and concentric arrangements of two or more bottles on "cullet" sizes were examined. Moreover the behaviors of the underwater shockwave were observed by framing photograph method, shadowgraph method, illumination photography method and the FEM simulation was executed in order to make clear the high speed fracture mechanism.

The proposed technique is an efficient method for the crushing of glass bottles. In this study, the influence of various explosive conditions, that is, the explosive shape, set position, amount, the bottle size and the contents of bottle, on the cullet size, which is the crushed glass fragments, was studied. Furthermore, the behaviors of underwater shock wave were observed by high-framing photograph and the high-speed fracture mechanism was clarified.
