Abstract

This Automatic Can and Bottle Crusher for Waste Management project aims to solve the disposal problems that occur in aluminium cans and also plastic bottles. This project is to produce a prototype that has good crushing efficiency, low cost, affordable and suitable for different types of company use. Three conceptual designs have been proposed, and conceptual design with using pneumatic system has been chosen as the final design after comparison. SolidWorks was used to develope the 3D model for this final design. The working principle of the design is using pneumatic cylinder with the help of timer to automatically extend and retract the stroke to operate the crushing process of aluminium can and plastic bottles. After feeding the aluminium can and plastic bottle into the feeder, the feeder will feed the aluminium can and plastic bottle into the crusher and let the pneumatic cylinder to crush the aluminium cans and bottles. The prototype has the capability to crash two cans at once. By having a timer set to 4 second of extend and retract respectively, the efficiency of the can crusher was 7.5 cans per minutes by crushing one can per time and 15 cans per minutes by crushing two can per time. A average 75.17% length reduction of aluminium can and 66.04% length reduction of plastic bottle can be done by using the prototype. This project aim to achieve the Sustainable Development Goals No. 12 which is ensuring the sustainable consumption and production patterns
