Pepsi bottles: no more plastic – the title is a bit misleading, as they’re just testing this.

Anyways, this sounds interesting, but I’m also somewhat curious on the overall cost/benefit of this. We’ve heard that using Ethanol for fuel has ended up causing food shortages around the world, so what about using plant material for plastic? The article notes that they may be using plant-based wastes, and if so I assume that’s good.
