Biogreen has revolutionized the seemingly un-revolutionizable water bottle market by releasing a biodegradable, BPA-free water bottle. They're dishwasher safe, the break down in landfills, and they don't pump you full of endocrine disrupting bisphenol A*.
Biogreen makes the bottle in many sizes, from 14 ounces through 32 ounces.
On a personal note, I enjoy the product for several reasons. It's a quality water bottle that, unlike some cheap water bottles, doesn't leak out the top while you drink. Also, I don't have a dishwasher, so my water bottles get stinky after a short while. This allows me to chuck the old water bottle without being too much of a litterer. Finally, the bottles are cheap. A reusable 32-ounce bottle is approximately the price of three 32 ounce gatorades.
