A new and innovative process by which plastic and aluminium laminate cartons, such as those used for fruit juice, are broken down using microwaves, separating the aluminium and plastic so that they can be recovered, has been honoured at an awards ceremony at the London Science Museum. The process, which won the Institute of Chemical Engineers' (IChemE) BOC Environment Award, was developed by scientists at Cambridge University, and uses a technique known as microwave-induced pyrolysis.
