From Peter Leach
Katharine Sanderson sets out the wondrous potential of new 2D materials such as graphene (25 October, p 40). Like all good things, however, there may be a downside overlooked in the excitement of discovery.
A key property of graphene is its high strength and, presumably, durability. So what are the likely consequences of a world suddenly awash with stuff made from these new materials? I trust that, this time, someone considers the recyclability and end-of-life issues for each new material before it becomes a problem and not afterwards. But I’m not holding my breath.
