Feasibility study for asphalt rubber pavements in Norway. ‘Rubber Road’ feasibility study.
RubberRoad proposes to use rubber from used tires in the production of asphalt for road and bicycle ways. This recycling approach has not gained much attention in Norway despite its apparent advantages, such as noise reduction, increased durability, safer shock impact, and reduced climate and environmental impacts. The Life Cycle Analysis carried out during this project feasibility study has demonstrated a series of environmental benefits in the use of rubber in asphalt production. It has also helped identify relevant knowledge gaps related to the use phase of the rubberized asphalt and its impact to noise, air and micro-plastic pollution. Better understanding of these effects would probably result in even larger environmental benefits of rubberized asphalt with respect to standard asphalt production. However, while the tire recycling industry is generally positive to the disposal of used tires in asphalt production, additional incentives need to be put in place for the Norwegian asphalt producers to consider actively contributing to this development.

Fate of Springtime Atmospheric Reactive Mercury: Concentrations and Deposition at Zeppelin, Svalbard
Mid-latitude atmospheric elemental mercury (Hg) emissions undergo extensive oxidation to reactive Hg (RM) compounds during Arctic polar sunrise, resulting in enhanced atmospheric deposition that impacts Arctic marine wildlife and humans. It has been difficult to estimate RM dry deposition, because RM concentrations, compounds, and their deposition velocities are ill-defined. Here, we investigate RM concentrations sampled with membrane-based methods and find these to exceed denuder-based RM detection by 5 times at the Zeppelin Observatory on Svalbard (March 26–July 24, 2019). Measured dry deposition of gaseous oxidized Hg was about half of the modeled RM deposition, demonstrating that particulate-bound Hg was an important component of dry deposition. Using thermal membrane desorption, RM chemistry was found to be dominated by Hg–Cl/Br (51%) and Hg–N (45%) compounds. Back-trajectory analysis indicated that Hg–Br/Cl compounds were predominantly advected from within the marine boundary layer (sea ice exposure), while Hg–N originated from the free troposphere. Weekly average RM compound-specific dry deposition velocities ranged from 0.12 to 0.49 cm s–1, with a net RM dry deposition of 1.9 μg m–2 (1.5–2.5 μg m–2; 95% confidence interval) that exceeds the mean annual Hg wet deposition flux in Svalbard. Overall, we find that springtime atmospheric RM deposition has been underestimated in the Arctic marine environment.
