Professional shippers also cram their boxes full of material to protect cargo, and most of that stuff (like bubble wrap and foam peanuts) presents a disposal problem for the receiver, since it's largely not recyclable. I came across this Wired article that describes a sustainable alternative that relies on cleverly folded cardboard pyramids.
The ExpandOS solution was invented by William Oliver, who in a former life designed machine tools for Ford and Mercedes. After a failed attempt to create molded paper pulp cubes for packaging, he came up with a machine tool that could cut and fold small paper triangles. The complete system includes paperboard sheet material that is fed into an expander, which spits out thousands of the tiny structures per ream of material. They're serrated on the edge, and lock together when packed around an object. Different thicknesses are available for different applications.
To prove its strength, the company sends potential customers a box containing a brick, a coffee mug, and a light bulb packaged in the material. So far there's only been one broken cup. Check out the videos below to see how material works.
