INTRODUCTION
Ever wonder how a single journey can spark an idea and completely rethink a conventional business model? Luc Menetrey is a perfect example. He forges new paths through every stage of the value chain of his Greenfib bio-based high-performance polymer. Fun quiz: what do castor seeds and oyster shells have in common? Besides being part of the materials chosen to make objects reusable, refillable, and returnable.
Enjoy listening to our second deep dive of Hidden Resources, the new interview series within Unboxing Your Packaging.
Discover how circular packaging solutions really work: from material choices and design to resource flows and real-world challenges.
Structured insights, honest conversations, and practical frameworks you can apply: all based on the Develop Circular Packaging Solutions training.
No sponsors, no fluff, just circularity in action!

Luc Menetrey is the co-founder and inventor of Greenfib, a biomimetic material designed with end-of-life management integrated from the start.
Originally trained and professionally established as an optician and eyewear maker, he began developing new material solutions after a personal experience in the Senegalese bush. Since 2008, he has been working in plastics processing and material development, with a strong focus on the chemical and technical dimensions of materials. Passionate about science and driven by curiosity for how systems function – whether technological, geopolitical, or human – he developed Greenfib to challenge conventional material choices in eyewear and beyond, drawing inspiration from biomimicry and circular design principles.
He believes it matters more to be the first to leave a trace than to make the most beautiful one in the moment. He often describes himself as “Epicurious and Happycurian,” and lives by Carpe diem. He is inspired by Ralph Waldo Emerson’s words: “Do not go where the path may lead—go where there is no path and leave a trail.”
PODCAST MUSIC
Special thanks to Joachim Regout who made the jingle. Have a look at his work here.
I am happy to bring a sample of our strong bonds on these sound waves. Since I was a child, he made me discover a wide range of music of all kinds. I am also delighted he is a nature lover and shares the Look4Loops 'out of the box philosophy'. He is an inspiring source of creativity for me.
