Here's a minimal mockup of how the iconic classic coke, in a can, could look. Not only does it look awesome, as you can read below, the removal of the color paint in both the production and recycling process reduces the amount of energy needed to create the can.

A convex logo substitutes colorfully sprayed can. The naked can helps to reduce air and water pollution which typically occurs during the coloring process. It also reduces the energy and effort to separate the toxic color paint from aluminum during the recycling process. Huge amounts of energy and paint required to manufacture the colored cans will be saved. Instead of toxic paint, manufacturers process aluminum with a pressing machine that indicates the brand identity on surface.

Simple and elegant, what other products could we apply a similar process or mindset too, which would create interest while saving our environment?
