Future recyclability of asphalt reduces the CO2 emissions considerably

In the asphalt industry a lot has been done to reduce CO2 emissions. With the re-use of reclaimed asphalt from former asphalt roads in virgin asphalt mixes the emissions are reduced further more. As an example the emissions of a “25% re-used” asphalt mixture is almost 20% less than those of “all virgin materials” asphalt mixture. If you additionally consider the future recyclability of this asphalt material you even get further reductions of the CO2 emissions up to almost 60%.

Remark:

  • 15.6 kgCO2e/t for full virgin compared with 12.9 kgCO2e/t for 25% re-used is a reduction of almost 20%.
  • 15.6 kgCO2e/t for full virgin compared with 6.4 kgCO2e/t for 25% re-used and future recycled asphalt is a reduction of almost 60%
