Traditional fire retardants are chemicals used to prevent or delay the formation of flames and the spread of fire. Most contain persistent organic pollutants and hazardous chemicals that have long-term environmental and health impacts. 

In this project, Noignis, Nordicflexhouse, Quantbiores (QBR) and the Danish Technological Institute collaborate to develop natural foaming agents for bio-based fire retardants through sustainable microalgal production. 

Nature offers solutions like the foam formed on beaches, known as "sea foam," created by the decomposition of organic matter from microalgae.  Non-toxic marine microalgae release large volumes of foam when broken, which could be used as an eco-friendly fire retardant. 

Using fish farming wastewater, the partners will cultivate microalgae in a BioPod to produce foaming agents. A cutting-edge platform from QBR, employing specialized light frequencies, will boost algal production energy efficiency by 40%. The resulting foaming agents will be used in bio-based fire retardants.
