Bio-asphalt? Eco-friendly Alternative to Petroleum Derived Asphalt

Bio-asphalt? Eco-friendly Alternative to Petroleum Derived Asphalt

Research in microalgae as a petroleum alternative has led to discoveries that could change the way we build roads. Currently asphalt is a concrete made with viscous form of petroleum. Eco-friendly alternatives could significantly reduce costs, pollution, and carbon emissions that are associated with refining petroleum based products.

Bio-asphalt made from Algae would chemically be different from petroleum asphalt, but it would share the same binding properties that petroleum has (CNRS). Currently, regional funded research called the ‘Algoroute Program’ is underway in France. So far they have determined that microalgae have the same binding properties and viscous nature as asphalt. They are conducting more studies to make the production process more efficient and cost effective (Emmanuell et all, 2012).
