Nathalie Rykiel has designed this colorful graphic for Coca Cola’s aluminium bottle. Aluminium or glass bottles, what’s most environmentally friendly? Reading about the subject and you will find many different answers and opinions. Good thing with both materials is that they are 100% recyclable. But they have different impacts in different stages of the life cycle. To simplify it; Aluminium takes more energy to get out of the ground, but less to transport. Glass is much more energy efficient to create, but is heavy and fuel-intensive to transport. Now, taking usability into consideration; people handling the packages - retailers, consumers and so on – probably appreciate a light-weight package…and some people think transparency is important….you see, we can go on and on.
