Lignin, one of the main building blocks of a tree, is renewable and bio-based, and can be used as a responsible alternative for fossil-based binders in bitumen, for instance.
The new asphalt mixture was used to pave part of the wood field at
Lignin is a natural binder in wood that can be used as a substitute for oil-based bitumen in asphalt. The purpose of the test paving is to determine the overall impact of lignin on the properties of asphalt and its carbon footprint. Lignin can also be used as a substitute for fossil-based raw materials, for example, in batteries and adhesives.
The test will monitor the load and wear resistance of the test pavement, including its ability to withstand weather and seasonal variations, high loads and torsional forces.
'We see this as an excellent development for our mill. We are proud to bring a more environmentally friendly asphalt made from our own Lineo lignin to the
'We are doing our part to develop our operations and products to reduce our carbon footprint. The practical coating applications provide us with important information for further development. This project is linked to our efforts to replace fossil fuels and raw materials with bio-based products. Last year, Peab launched ECO Asphalt, which replaces fossil fuel with biofuel,' says Nina Orttenvuori, Research and Development Manager at
