OK, the real answer to the plastic water bottle problem has been with most of us all along. Its coming out of the tap in your house and you can drink from it any time you'd like (right now even). Fill up a steel water bottle and you're good to go. But there are those areas of the world where bottled water is still a necessity and thankfully, a company named Brandimage has the answer.
And if you are redesigning a sustainable water bottle, why stop there right? They've even eliminated the need for packing pallets and plastic wrap by designing the bottles so they can be linked together into their own carrying case.
