Bottle

Most water in stores today comes in bottles made from petroleum-based plastic. After drinking the contents, too many of these bottles become a pollution problem. Cove is looking to change that with the launch of its biopolymer-based water bottles.​

PepsiCo says it has developed the world's first polyethylene terephthalate (PET) plastic bottle made entirely from plant-based, fully renewable resources including switch grass, pine bark and corn husks.

Researchers from Stellenbosch University have patented a "tea bag" style water filter.

Bobbles are reusable plastic water bottles that have an activated carbon filter built into the drinking spout.
