278: Orange juice bar – circular economy


Machines for making fresh orange juice, usually throw away the peel.


The Circular Orange Juice Bar

Carlo Ratti Associati in Turin and energy company Eni have created “Feel the Peel”, a Circular Orange Juice bar which supplies freshly squeezed juice in a 3D printed bioplastic cup made from the orange peel.

The prototype machine is 3.1 meters tall and has a circular dome which holds 1,500 oranges. When you order an orange juice, an orange slides down, is cut in half, and juiced. The peel is then dropped into a container at the bottom of the machine and the leftover rinds are dried and milled to make “dust“. This is then mixed with PLA pellets to create a material ready for 3D printing into a cup. The 3D printer – presumably provided by Wasp, whose logo is emblazoned on the side of the unit – resides in the middle of the juice bar.

Visitors can watch as their cup is created and then filled with juice. After the drink is finished, the cup can be recycled. It could potentially be broken down and re-made into another cup to keep the circular economy going. In October 2019, the Circular Juice Bar was trialled at the Singularity University Summit in Milan, Italy.
