Shell’s Bitumen CarbonSink used for the first time in France to help decarbonize construction
Shell Bitumen CarbonSink, Shell’s new bio-component binder that traps carbon in roads instead of releasing it into the atmosphere, has been used for the first time in France.
Karp-Kneip Constructions led the project, where 20 tonnes of Shell Bitumen CarbonSink were used to build a car park at the Brumath Enrobés asphalt production plant in Bas-Rhin, Alsace. The asphalt for this project was laid by the civil construction company Trabet.
Shell Bitumen CarbonSink contains a new biocomponent binder that traps carbon in asphalt and bitumen, turning the road into an engineered carbon sink. The high level of recycling of asphalt worldwide ensures that the carbon remains locked in the binder, even when it is recycled and reused in the manufacture of new asphalt or other civil engineering applications.
“Decarbonizing the construction industry is a challenge that will require efforts from every link in the value chain, and this project is a great example of this kind of cross-industry collaboration,” said Ana Alvernhe, Managing Director for the Europe, Shell Construction. and Road. “At Shell, we want to use our experience in the energy sector to deliver innovations that can support our customers’ net zero ambitions. So it’s fantastic to see Shell Bitumen CarbonSink being used for the first time in France, helping to drive the decarbonization of construction in another important market.
The technical carbon sink created by Shell Bitumen CarbonSink retains up to 250 kg of CO2 equivalent in each ton of bitumen and up to 13 kg of CO2 equivalent.1, 2 in every ton of asphalt. This means up to six tonnes of CO2 the equivalent can be blocked per kilometer of road.3
Shell Bitumen CarbonSink, which has already been deployed in the UK by Aggregate Industries for its SuperLow-Carbon asphalt, is being launched in several markets for large-scale use on the global road network.
