Terracycle Speakers: these M&M speakers done by Terracycle are made with recycled M&M boxes, in fact everything Terracycle makes were previously trash, which in the green world, we call this process upcycling. They also donate a small percentage of each trash a school or an individual sends them and so far have donated over $1.5M. You can also find other cool gift ideas such as a circuit board desk clock, a bike chain frame or an Oreo wrapper kite.
