Bioasphalt : from microalgae to "green roads" ?

Microalgae offer a highly promising alternative to petroleum products without competing for resources used in the food industry. They have now been used for the first time to make — asphalt! Researchers at the CEISAM (Chimie et Interdisciplinarité: Synthèse, Analyse, Modélisation - CNRS / Université de Nantes), GEPEA (Génie des Procédés Environnement et Agroalimentaire - CNRS / Université de Nantes / ONIRIS / Ecole des Mines de Nantes), IFSTTAR (Matériaux pour Infrastructures de Transport) and CEMHTI (Conditions Extrêmes et Matériaux: Haute Température et Irradiation - CNRS), working in collaboration with the company AlgoSource Technologies, have proved the viability of bioasphalt, demonstrating its close similarity to the “real” asphalt used to pave roads. Their findings have been published in the April issue of ACS Sustainable Chemistry & Engineering.
