Foamlab is a Delft-based startup that leverages microorganisms to create bio-based foams from bacterial cellulose. These foams are lightweight, durable, compostable, and customizable, offering a sustainable alternative to traditional oil- and mineral-based foams. The company aims to substitute these materials in sectors like construction, furniture, fashion, and packaging. Foamlab's unique selling proposition lies in its control over the nanoscale structure of the material through microbial biofabrication, allowing for precise tuning of mechanical, acoustic, and aesthetic properties while maintaining biodegradability and low-impact production.
