Bio-asphalt

Asphalt is held together by bitumen from crude oil. This fossil adhesive can be replaced with bio-based resources that do not generate any additional CO2, say Wageningen scientists. Together with industry and government, they are studying lignin, a substance in wood that gives trees and plants their rigidity.

They have been able to use this lignin as a natural adhesive in asphalt. This year, the first strips with bio-asphalt will be tested, also concerning aspects such as rolling resistance and noise. Bio-asphalt is beneficial for the environment. As a result, Wageningen UR is improving the quality of life.
