Graphene is a sophisticated, man-made material discovered only a few decades ago. Okay, technically, you can make graphene by sticking a piece of tape onto the “lead” of a graphite pencil and then peeling the tape off. Graphene is not particularly useful in that form, however. Researchers want to make large sheets of graphene, which could then go next-generation electronics. Many labs are researching both ways to use graphene in electronics and ways to make enough graphene should electronics factories one day require it. But the PlasCarb project is the first we’ve heard of turning food into graphene.
