What you see above is the process by which trash is made into trash cube seating: discarded bits of material used to make molding tiles for architecture are squashed together with flowerpots and left to dry.
Designed by Nicholas Le Moigne of Switzerland, the scrap fibre cement used in the chair is plentiful, and usually ends up in the landfill. Instead of throwing the material in trash bins, the leftover material is thrown directly into the cube-making device and left to set. The cubes sell for around 100 euros.
