Link: Making Plastics From Oranges.
Researchers at Cornell University have made a brilliant and environmentally friendly discovery: plastics made from orange peel and a greenhouse gas. By adding a zinc catalyst to a mix of citrus fruits, such as oranges, and carbon dioxide, they found a way to make a new polymer called polylimonene carbonate, very similar to polystyrene, a petroleum-based plastic. This is a double whammy: it will reduce existing carbon dioxide, almost certainly responsible for the global warming effect, while reducing future emissions. Of course, time will pass between this discovery and its practical applications. But ultimately, this will greatly beneficial to all of us.
