Our Clim@Add® aggregate is a very versatile material. In addition to incorporation into concrete, we have identified another field with high scaling potential in asphalt production. Even at a low dosage of 2%, for example, 6,000 tons of CO2 can be stored each year in the case of an annual production of around 100,000 tons of asphalt. We have therefore optimized our Clim@Add® aggregate for use in asphalt.
In Germany, over 80% of asphalt pavements are recycled and used for the construction of new roads. But despite the high recycling rates, the carbon footprint of asphalt production remains high. Our Clim@Add®AC can save further emissions here as an additional carbon sink. At the same time, the compound remains stable even after countless recycling cycles, as the Clim@Add®AC becomes part of the matrix of the asphalt and remains permanently intact.
We currently assume that up to 5% Clim@Add®AC can be incorporated per ton of asphalt. With an annual production of around 20 million tons of asphalt mix in Germany in 2021 alone, this could save over 2 million tons of CO2.
CarStorCon® Technologies
short and sweet
1 kg of Clim@Add® can store up to 3 kg of CO2.
Clim@Add® is easy and direct to install.
Clim@Add® can be used to adapt material properties and thus replace additives from fossil raw material sources.
At the end of 2020, we have already realized the first successful trials with Clim@Add®AC. Within the scope of a pilot project, we have installed the road surface after connecting new users to the district heating network....
