I was wondering which drink container is the most sustainable one, when looking at the big picture (complete life cycle analysis).
So far, I can see the few following points:
- Transport: plastic and aluminium are lighter than glass, and they can be crushed on their way to recycling, which means less transport-related use of energy.
- Raw material: I think glass is probably the most sustainable in terms of resource availability and number of recycling cycles - is that right?
- Pollution: again, glass would be the best at not disrupting the environment.
- What about the energy needed for recycling each of those products?
I reckon this should be assessed on a contained liquid volume base.
