Colourless Coke Cans
A convex logo substitutes a colourfully sprayed can. Instead of using toxic paint, manufacturers process aluminum with a pressing machine that indicates brand identity on its surface. This manufacturing process will save huge amounts of energy and paint that are usually required to manufacture coloured cans. Naked cans also help to reduce air and water pollution that occur in the colouring process. In addition, this reduces the energy and effort needed in separating the toxic paint from aluminium in the recycling process.
