Skylar Or is there some other better option than glass or plastic that I am missing?
Aluminium is 100% recycable like glass (if we are talking about packaging not the specific glass like windows and others), it is very energy efficient, durable, flexible for different shapes, is okay with contact with different materials, is transportation friendly. The problem is recycling, but in EU is getting better and better.
About the glass, well if we would recycle it and would not keep the massive unused amounts at home it is great because it can be recycled and recycled for all it's life.
