Italian studio Carlo Ratti Associati has developed a circular orange juice bar that turns the waste fruit peel into 3D-printed bioplastic cups to drink the contents from.
Created for global energy company Eni, Feel the Peel is a prototype orange-squeezing machine that aims to bring circular design into everyday life.
The 3.10-metre-tall experimental juice bar is topped by a circular dome filled with 1,500 oranges. When someone orders a juice, the oranges slide down into the squeezer where they are cut in half and juiced.

After being juiced, the leftover orange peel falls into a see-through compartment at the bottom of the machine. The collected rinds are then dried and milled to make "orange dust", which is mixed with polylactic acid (PLA) to form a bioplastic material.
This material is then heated and melted to form a filament, which is fed through a 3D printer incorporated into the machine.

Visitors can watch the printing process as it builds up concentric layers of the filament, before using the finished product to drink the freshly-squeezed juice.
The cup can then be recycled after use, to complete the circular design.

"The principle of circularity is a must for today's objects," said founder Carlo Ratti. "Working with Eni, we tried to show circularity in a very tangible way, by developing a machine that helps us to understand how oranges can be used well beyond their juice."
According to Ratti, the next iterations of Feel the Peel migh...
