Today I have discovered from watching a documentary on the efforts to go green in Sau Paulo, that the waste product after recycling paper and aluminum foil out of them can be used to manufacture roof.
You can read the recycling process for aluminum and the production process for roof off websites of Tetra Pak.
But roofs out of used packaging? Are they durable? Check them out in this video.
Hmmmm... It's time to look at Tetra Pak packaging waste more seriously.
