About
Foamlab is a Delft, Netherlands-based biomaterials startup developing high-performance, compostable foams from bacterial nanocellulose produced through microbial fermentation, designed to replace fossil-based plastics such as polystyrene 13. The technology, originated from Delft University of Technology’s Faculty of Industrial Design Engineering, produces foams with tunable properties suitable for packaging, textiles, furniture, insulation, and construction applications 12. Foamlab was spun out of TU Delft in 2022; Professor Elvin Karana serves as co-founder and technology lead, and Jeroen van Rotterdam is co-founder and CEO 3.
