DECARBONISATION OPTIONS FOR THE DUTCH ASPHALT INDUSTRY - C. Oliveira, C. Xavier Silva

Summary

Depending on the sourcing of the lignin, this alternative could reduce the indirect emissions of the sector and the dependence on the refinery sector, which is the supplier of fossil-based bitumen. [...] Figure 3 Hot and warm mix asphalt mix production in the Netherlands (EAPA, 2020) Little data is available for 2020 regarding the asphalt production in the Netherlands, however, in 2017 out of the total 8.1 Mt, the application of the asphalt mix was allocated in this way: 38% Surface Course, 9% Binder Course, and 53% to the Base Course. [...] The virgin aggregates are fed to the end of the drum opposite to the burner and the recycled asphalt enters the drum halfway. [...] Figure 18 Total production of hot and warm asphalt mixes in Europe and in the Netherlands between 2013-2017 (based on data from (EAPA, 2020)) Regarding cold asphalt mix, the most recent available data for the Netherlands is from 2017 and the total production value was 23 kt, which represented 0.3% of the total asphalt production in the country for the same year. [...] The results of this study show that converting natural gas to blends in an old plant can impact directly the thermal output because in general the larger the hydrogen concentration the lower the LHV (MJ/m3) and the higher the adiabatic flame temperature.
