The cacao husk, a waste product from the chocolate industry, is often overlooked due to its inherent bitterness. Typically discarded by ending up in landfills, we recognized the untapped potential within this resource, given its rich fiber and cellulose content. Exploring this potential by employing different techniques and composite formulations, we created a series of materials that closely resemble the visual appeal of chocolate while also evoking universally positive memories through its distinct scent. We successfully developed a sheet material comparable in processing and manufacturing to Medium-Density Fiberboard (MDF) and fiber-reinforced compostable PLA composite for 3D printing.
In collaboration with various partners, including Rittersport, material scientists, and woodworkers who conducted comparative analyses, our efforts garnered recognition and were nominated at MaterialPREIS 2020.
Furniture designs with a striking contrast between cold aluminum and warm cocoa material showcase the quality and durability of recycled waste. A versatile side table features a removable tray for a tactile experience, while a wall lamp emits fragrance and adjusts scent intensity with light. These designs redefine possibilities, blending functionality, aesthetics, and indulgence while promoting sustainability and mindful decision-making.
Designers carry a responsibility to navigate the deployment of influential material carefully. Memories and emotions evoked through a simple scent prompted us to contemplate the roles designers and makers can assume in advocating sustainable interactions with materials.
