I read an article a while back that I have been meaning to share. It describes how many Coke cans are sold every year and suggests that if they went with a ‘naked’ design, i.e., no paint on the can, then
naked can help to reduce air and water pollution occurred in its coloring process. It also reduces energy and effort to separate toxic color paint from aluminum in recycling process. Huge amount of energy and paint required to manufacture colored cans will be saved. Instead of toxic paint, manufacturers process aluminum with a pressing machine that indicates brand identity on surface.
I am sure that there would also be some energy and pollution savings when the cans get recycled.
You may be wondering how many Coke cans are sold every year? The article looked up some figures from 2007 and came up with almost 25 billion or 25,000,000,000 worldwide. Can you image if Coke, Pepsi, and all of the other cola and beer manufactures went this route how much pollution and energy could be saved?
