HIGH APPLICATION POTENTIAL
Roads, footpaths, cycle paths and more

AVOID THE NEED FOR CARBON OFFSETS
Achieve net zero asphalt without having to purchase offsets

Carbon Footprint

1 tonne of ACLA® has permanently removed 750kg CO₂e from the atmosphere. This is a cradle to gate (A1-A3) carbon footprint value, meaning it has taken into account the carbon emissions and benefits associated with raw materials and the production of ACLA®.

ACLA® is a carbon-negative aggregate which acts as a permanent carbon storage solution for the decarbonisation of asphalt.

ACLA® utilises the carbon removal technology of sequestration to permanently remove carbon dioxide from the atmosphere.

Sequestration is the process where a material captures and stores carbon dioxide to prevent its release into the atmosphere.

Asphalt roads account for over 95% of all UK roads, and 25 million tonnes of asphalt are produced annually (Asphalt Industry Alliance, 2021). Tackling the emissions of asphalt is, therefore, vital for the UK road network to decarbonise in line with the country’s legally binding target of achieving net zero by 2050.

Typically asphalt generates emissions of 30-70kg CO₂e/tonne.

To achieve net zero, 5-7% of ACLA® by weight of the total asphalt mix is likely required depending on the embodied carbon of the mix designs.

Applications

ACLA® is a carbon-negative aggregate that was developed by Low Carbon Materials which is now being tested with National Highways and Skanska as part of the Accelerating Low Carbon Innovation Programme. It can be used as a replacement aggregate to significantly lower the carbon footprint of asphalt.  

ACLA® can be easily incorporated into a standard asphalt mix.

Due to ACLA® having a lower density than typical aggregates it is estimated that 1.7kg of traditional aggregate should be removed and substituted with every 1kg of ACLA® required.
