This year saw the launch of Nypol RE from Nynas, a polymer modified bitumen (PMB) containing biogenic material. But the specialist bitumen supplier's interest in plant-derived materials, and their potential role in creating more sustainable pavements, dates back much further. "We started with studies into biogenic materials in our own laboratories back in 2012 and went on to work with universities and other independent researchers, before moving onto field trials," recalls Jenny-Ann Ostlund, sustainable development & technology director for bitumen at Nynas. |
