In the past, fields of wheat and rows of potatoes were seldom destined for anything more than a rumbling tummy. But bio-products have come a long way since people first branched out into weaving hemp into clothes and pulping papyrus into scrolls. Today the line between Mother Nature and man made has never been more blurred. Animals are re-engineered into living drug factories, crops fuel our cars and now plants are increasingly being repackaged as the epitome of the synthetic world – plastic. Wheat, maize, vegetable oils, sugar beet and even the trusty spud are finding new life as water bottles, car fuel lines and laptops.
