When digital technology participates to reduce the cost of transportation, check Industrial Origami:

Shipping in the Flat. The Industrial Origami “smiles” can be stamped or cut into the flat sheet material. The products can then be shipped in the flat and subsequently folded upon delivery. Because parts are shipped in the flat, more pieces can be put in containers, reducing the need to ship “air” and creating a higher density shipment. Special handling of complex parts is reduced, reducing shipping costs and damage.

Could be awesome if also made of recycled material.
