With the help of Shell Bitumen, Aggregate Industries has developed SuperLow-Carbon; the innovative next step on the carbon reduction journey.
The evolution began by reducing the embodied carbon footprint of our asphalts: improving production processes, using alternative energy sources, and mixing at reduced temperatures. In SuperLow-Carbon, we have gone even further, including a biogenic material within the bitumen that effectively locks carbon within the asphalt rather than releasing it back into the atmosphere.
The use of these biogenic components in SuperLow-Carbon means that CO2 remains within the asphalt even when it is recycled, creating a carbon sink.
