Biobased asphalt with lignin can cut emissions up to 60%
The Dutch asphalt sector can reduce emissions by 30% to 60% by using biobased asphalt in which fossil bitumen has been replaced by lignin and other components from plant residues, according to new figures from Wageningen Food & Biobased Research. The potential savings are huge, since 10 million tonnes of asphalt containing 300,000 tonnes of bitumen are produced annually in the Netherlands alone. In traditional asphalt, bitumen is used as a binder. It binds the gravel in the asphalt mixture together and gives strength. However, bitumen is a crude oil product that is becoming…
