Effective waste management is key to creating more sustainable cities. This study explores a straightforward but impactful way to enhance waste collection efficiency – by optimizing the compaction of metal cans. Various methods of compressing metal containers, including hand and foot compression (middle, full diameter, and full height), were tested to see how much they could reduce the volume of these cans. Our simulations showed that full-height and full-diameter compression were the most effective, significantly increasing container capacity by minimizing empty space. This approach is not only practical but scalable, offering waste management operators a clear pathway to improving resource efficiency. Beyond the immediate benefits of reduced collection frequency and lower fuel consumption, this method contributes to broader sustainability goals by minimizing the carbon footprint associated with waste management. These findings have wide-ranging implications, from urban policy-making to everyday waste disposal practices, highlighting a simple yet transformative step toward a cleaner environment.
