This week Winn-Dixie will introduce Primo water in more than 500 stores, debuting what Primo To Go, the product's manufacturer, said is the only single-serve water in the U.S. in bottles made from plants, not petroleum.

Winn-Dixie will celebrate the launch by giving shoppers a free case of Primo water from July 2-9, when they buy a new Primo three- or five-gallon Zero Waste water bottle. Winn-Dixie is the first grocer in the nation to promote both of Primo's more environmentally-friendly water options together.

Primo single-serve bottles are made from natural Ingeo plastic, which is made from plants grown in America, the Winston-Salem, N.C.-based supplier said. The bottles can be recycled through traditional methods, sent to degrade in a commercial composting facility, or incinerated for energy recovery, according to Primo Water,

Primo single-serve bottled water is sold in a multi-pack of 18, 16.9-ounce bottles at a suggested retail price of $4.99. Primo 3 and 5 gallon Zero Waste water bottles are available nationally for $4.99 and $6.99 respectively.
