Did you ever wonder what happens to all those millions of plastic bottles after you put them in the recycling bin? Prepare to be surprised - Marks & Spencer and British Home Stores have recently announced they would each be selling a range of schoolwear made from recycled plastic bottles. The bottles have been chopped up into flakes, melted and then made into a polyester yarn, which is woven into cloth. The end result is a range of fleeces, polo shirts, trousers and skirts that will go on sale in the summer, and apparently don't melt under an iron. I'd watch out for those lunchboxes though, if I were mum!
