Coloured scanning electron micrograph (SEM) of material from a biodegradable carrier bag. It is made from polylactic acid (PLA), a plastic substitute derived from fermented plant starch, most often corn starch. Starch grains (green) can be seen in the material. Magnification: x3000 when printed at 10 centimetres wide.
