The eco bottle

The Numbers Guy takes a look at the new water bottles.

It’s not uncommon for bottled-water companies to tout the purity of their waters. But one giant bottler has gone one step further: boasting about the bottles themselves.

Nestlé claims it offers the lightest half-liter bottles in the U.S. market. Earlier this year, it introduced new, sculpted bottles with labels stating they contain “30% less plastic.” On Web sites for its brands Poland Spring, Ozarka, Arrowhead and Ice Mountain, Nestlé clarifies that this isn’t a 30% reduction from the old model, which is still in distribution; instead, its new “Eco-Shape Bottle” has 30% less plastic “than the average half-liter bottle.”
