Amongst latest French foodie news, i read that Brita is about to introduce (in France) the first biodegradable bottle made from vegetable sources and shaped like an ear of corn.
I hope the base is flat (for convenience).
A pointy base would not be much of an issue at the shore (as we say in New Jersey), the beach for the rest of the world.
You could just stick your bottle in the sand and not worry about living it there as it is biodegradable.
Are bio-degradable wine bottles on the way?
