A Compostable Lamp Made from 3D-Printed Orange Peels Proposes a Sustainable Use for Food Waste

Part sustainable design and part ode to Sicilian food culture, a new product by a Milan-based startup transforms inedible food waste into a functional homeware. Krill Design’s “Ohmie” is a compostable lamp made from the peels of two to three oranges sourced from the Messina province that are dried, ground into a powder, and added to a biopolymeric vegetable starch base. That combined material is molded into pellets used in a 3D printing process that layers the vibrant matter into a textured shade and base. Because of its organic origins, the minimal, leather-like lamp varies slightly in color as it ages and even maintains its signature citrusy scent.

“Ohmie” isn’t Krill Design’s first product that relies on a circular economy model: previous initiatives involve recycled plastics and coffee scraps that undergo a similar process before they’re molded into office furniture and other consumer goods. The orange lamp already met its goal on Kickstarter, but you’ve got about two weeks left to back the project. You also might enjoy this juice machine that creates bioplastic cups. (via Dezeen)

A New Circular Juice Machine Turns Orange Peels into Bioplastic Cups

September 9, 2019

Laura Staugaitis

Freshly squeezed orange juice is a welcome sight at cafes worldwide. The machines often showcase about-to-be-squeezed oranges with pinball machine-esque wire loading racks and clear cases that allow the consumer to see their juice being made in real time. International design firm Carlo Ratti Associati (previously) takes the immediacy of the experience to another level. ‘Feel the Peel’ is a prototype machine that uses orange peels to create bioplastic, shaping bespoke cups to hold the juice made from the cups’ own innards.

In a press release about the project, Carlo Ratti Associati (CRA) explains that the approximately 9-foot tall machine handles 1,500 oranges, and the peels accumulate in the lower level. The peels are dried, milled, and mixed with polylactic acid to form a bioplastic, which is then heated and melted so that an internal 3-D printer can form each recyclable cup. CRA shares that they will continue to iterate, and are considering creating clothing from orange peels as a future functionality.

Follow along with CRA’s wide-ranging projects on Instagram and Twitter.

The Energy Generated from A Single Orange: A Citric Acid Battery by Caleb Charland

November 15, 2012

Christopher Jobson

This orange battery was built by photographer Caleb Charland (previously) as part of his ongoing alternative energy photographs using fruit, vegetables, and other objects to create light for his long-exposure photographs. The electricity powering the lightbulb inside the orange is generated through a chemical reaction between citric acid and the zinc nails inserted into each wedge. I think this is by far the most lovely piece he’s done in the series, but before you start work on a bunch of orange lights to keep on the nightstand, the light generated was so dim this particular photograph required a 14 hour exposure.
