Coke upgrading all bottles. Now 30% plant material

Calling it the PlantBottle, Coke is changing all of their bottles to include 30% plant material.  The plant material is molasses and sugar cane which are leftovers from sugar making processes, which reduces the overall waste of the sugar refining process as well as giving Coke the perfect recyclable plant based matter to use in their bottle.  The change in their bottle will create an estimated 25% drop in the carbon emissions from the Coke product.  This is just a stepping stone towards Cokes official goal of having a 100% renewably bottle.  I did not see anywhere in the articles that I have read whether or not these bottles would then be biodegradable, but my assumption is that they are not now, but will be in the future.  See more on Inhabitat.
