Lineo™ by Stora Enso tested in asphalt on Swedish roads
Swedish road and infrastructure operator Svevia has decided to collaborate with Stora Enso in testing lignin in asphalt. Through this collaboration, Svevia aims to replace part of the oil-based binder with nature’s own binder – lignin, Lineo ™ by Stora Enso. The lignin containing asphalt is currently being tested out on Swedish roads. Svevia is carrying out road paving work on road 224 between the towns of Sandbrink and Gnesta on behalf of the Swedish Transport Administration. Of the total 15-kilometre stretch, Svevia has chosen to test Lineo™ on a couple of hundred meters, where lignin will replace bitumen. Lignin was chosen as it is a bio-based natural binder found in trees with the potential of reducing the negative climate impact of asphalt.
