France's Danone Dairy Produces Ecological Packaging

France's Danone Dairy produces a yoghurt box and cup made of lactic acid from sugar beets. The basic raw material of this ecological box (cup) is beet, which is converted into lactic acid by fermentation, and then the water is extracted to form propyl ester, which is then processed into polymil ester, which becomes a light and strong material after being mixed with minerals. Boxes (cups) made of this material can be broken down into farmyard fertilizers at 55°C for 60 days.
