Stockholm – Potato, wheat bran, lemons, limes and water… not a recipe for a particularly strange meal, but the components of the world’s first 100-per-cent biodegradable sound-absorbent material, Baux Acoustic Pulp, which launched at the Stockholm Furniture and Light Fair last week.
When mixed with sustainably harvested Swedish spruce and pine and plant-derived wax, these household ingredients become a strong, fire-resistant and water-repellent substance, which Swedish studio Form Us With Love has transformed into geometric wall panels for architects conscious of their environmental legacy. ‘The degradation of our natural environment is a global topic of increasing urgency, and we can no longer afford to turn our backs or cut corners,’ said Baux CEO Fredrik Franzon.
Since launching five years ago, Baux had tested between 50 and 60 materials before discovering a group of researchers from the Royal Institute of Technology that had found an ideal 100-per-cent bio-based solution using biomimicry – a process where you try to find answers from nature itself. ‘Previously we’d looked at using moss and different types of mushroom, but they always fell down on aesthetics, functionality or (the most challenging) fire-resistance, but then with this collaboration it all came together,’ explained Franzon.

Baux Acoustic Pulp finds its strength in citrus peel, which reacts with the fir’s cellulose molecules to create a super-strong binding. The mixture is spread into a 3D mold, with a strong honeycomb structure inspired by bees, pressed and dried under a 40-tonne vacuum and then nano-perforated for excellent sound absorption. Leftovers are recycled into the next batch and the entire factory runs fully on hydropower.
