Unlike traditional PET (polyethylene terephthalate) half-liter water bottles which weigh in around 13 to 16 grams, Sidel's NoBottle comes in at just under 10 grams. Though perhaps not very impressive in itself, when added up (160 billion liters of bottled water were consumed last year) the savings in terms of waste reduction become quite significant. So, no, we're not talking about losing the plastic entirely here (we wish), but this is still a big step forward for the beverage industry. Sidel used its proprietary plastic technology, dubbed Flex, to make this new "water skin." Because it is highly flexible and has shape-memory, Flex allows the bottle to spring back to its original shape upon being compressed or gripped in any way. The French company plans on officially unveiling the NoBottle at K 2007, an international trade fair, in October.
