In this episode we look at how a new plant-based bitumen will be incorporated into asphalt mixtures currently being developed. The hope is that this will allow clients to build roads that act as carbon sinks.

The reduction in carbon by using products like this could play a significant role in helping the UK achieve net zero. The engineers think it might be possible store up to a million tonnes of this renewable biogenic material within the Highways England strategic road network.

A single UK household uses up to 20 tonnes of carbon a year. So using biogenic asphalt in the English road network could save as much carbon as us used by 50,000 homes in one year.
