Heinz has done some fun QR Code campaigns in the past. Their most recent “Guess what my bottle is made of?” is to show off their more environmentally friendly bottles to their consumers. Their new bottles are made out of 30% renewable plant material and is still 100% recyclable. In addition to finding out these fun facts after scanned the QR Code, you can make a promise via the mobile site and Heinz will plant a tree for every promise received. When I scanned they had over 13,000 tress that they’re going to plant.
