Design Challenge IV Winners

These category winners and finalists were recognized for their product designs, in regards to their use of materials  that may be perpetually cycled, and consideration of the product cycle as a pathway to growing the circular economy.

Best Student Design: Rex by Mallory Barrett

Mallory Barrett, student at North Carolina State University, envisions an innovative solution to medical packaging waste. In the United States alone, an estimated 4 billion prescriptions are filled, and many curbside recycling programs do not accept pill bottles. REX offers reusable, stainless steel medicine containers that do not require adhesive labels, in a circular business model that eliminates the need for the constant reproduction of currently used plastic bottles.

Best Professional Design: Eco-Luggage by Taina Campos and Jeremy Godol of Frame Design Studio

Eco-Luggage rethinks the way we carry during travel or displacement, with easily detachable, multi-use components. Designers Taina Campos and Jérémy Godel of Frame Design Studio, put design for disassembly at the core of their approach to Eco-Luggage. Because it can be easily disassembled, individual parts can be repaired or replaced as needed - and at the end of use, they can be cycled as biological and technical nutrients.

Best Use of Aluminum: SolarCasting by Bert Green, Allison Warth, Andrew Fabian, & Ashleigh Otto of SolarMill

Developed by Bert Green, Allison Warth, Andrew Fabian and Ashleigh Otto of Solarmill, SolarCasting offers an innovative take on reclaiming and recycling aluminum. Using a solar furnace built from reclaimed parts, SolarCasting uses concentrated sunlight to melt a crucible of reclaimed aluminum which can then be poured into a variety of molds to produce mechanical or aesthetic objects. By combining the  one hundred percent carbon-free foundry with lead-free aluminum, SolarCasting creates an unbreakable chain of material reclamation without the need for fossil fuels.

Get inspired by SolarMill's innovative take on closing the loop by enabling small scale aluminim recycling. 

Best Use of Fusion 360: Leave No Trace Leaf Knife by Ari Elefertin & Matt Callahan Parsons School of Design The New School

Ari Elefterin and Matt Callahan of Parson School of Design, The New School, designed The Leaf Knife as the first product of Leave No Trace, a camping gear company for the circular economy. The duo developed an accompanying Leave No Trace service system that offers uses options for product care and equipment while keeping all technical materials moving through a perpetual cycle of use and reuse. The Leaf Knife’s design represents an effective blend of sculpting, parametric modeling and assembly joints using Autodesk Fusion 360.
