This packaging design idea for Coke bottles approaches eco-friendliness on several counts. For material, student designer Andrew Kim proposes plant-based material, while the the bottle's straight-edged shape and curved bottom is tightly stackable, thereby reducing wasted space in shipping containers, and in turn, reducing carbon emissions for the product's distribution. Additionally, the proposed material is crushable down to 34% the packages' original size in a pre-scored accordion fold, to encourage habitual recycling. This is a great example of how a few, well-thought out design decisions could impact mass habits, and in turn, encourage desirable effects on the larger scale.
