The plastic material from which the Actimel bottles are made is so-called “Green HDPE”. This polyethylene is chemically almost identical to conventional PE, yet is produced from sugar-cane based bioethanol, i.e it is produced totally from renewable resources and not from petroleum products. PLA, the material used for the new Activia yoghurt pots, is also made completely from renewable raw materials. The PLA (polylactic acid) is obtained from starch by fermentation and is also biodegradable. However with PLA Danone is not promoting the composting aspect but is encouraging other packaging manufacturers to also use PLA so that significantly large quantities come onto the market and make a PLA-to-PLA recycling plant an ecologically sound and economical proposition.
