If you've picked up a Pepsi can lately, you may have noticed the green messages they're trying to spread about the benefits of aluminum can recycling. The "Have we met before?" campaign will feature messages on billions of cans of Pepsi before the year end of 2008. Messages like "Recycling could save 95% of the energy used to make this can" will be the taglines featured. They should be in stores now, so take a look!
