Microalgae and waste biomass, here the future asphalt
An environmentally friendly asphalt, made of microalgae and waste biomass, including wood and sewage, could replace the common bitumen used on our roads.
In a statement to the Guardian, Bruno Bujoli, director of research at CNRS (Centre National de la Recherche Scientifique) at the University of Nantes, said: "The chemical composition of the microalgae bioasphalt differs from petroleum-derived asphalt, but initial tests have concluded that it also bears similar viscous properties and can bind aggregates together efficiently, as well as being able to cope with loads such as vehicles".
