NCC Green Asphalt ® reduces carbon dioxide emissions

The new low energy NCC Green Asphalt ®, is one of many environmentally friendly products NCC has developed in recent years.

By further developing production and blending methods, we have managed to lower the temperature of hot asphalt while maintaining quality. The environmental benefits include reduced carbon dioxide and nitrogen oxide emissions.

We are working to reduce the industry's environmental footprint

Society needs a functioning infrastructure and lower carbon emissions. NCC is working to reduce the industry's environmental footprint and developing sustainable, cost-effective future methods.

With Green Asphalt, NCC has found an environmentally friendly solution where quality and cost are the same as for traditional asphalt. The process is patented and the NCC Green Asphalt trademark is protected.

High temperatures used to be a must

Until now, high temperatures were a prerequisite to creating asphalt strong enough for highways etc. Most of the asphalt produced for, and laid on, Swedish roads is produced at high temperatures. This means that aggregate and bitumen are heated and mixed at high temperatures.

The traditional asphalt production process is both energy-consuming and expensive. For each ton of asphalt produced, it takes approximately seven litres of heating oil. In Sweden, around seven million tonnes of hot asphalt are produced every year. This means that the industry uses about 50 million gallons of fuel oil every year, with corresponding high carbon emissions.

Lower temperatures afford greater environmental savings

By lowering the temperature of asphalt production to 120 °C, carbon dioxide emissions are up to 30 percent lower. And emissions of nitrogen dioxide, sulphur dioxide and carbon monoxide are drastically reduced.

The temperature reduction is also an environmental benefit from a workplace environment point of view. There is less smoke and odour. Dust particles in the air are reduced and also emissions of volatile organic contaminants and aromatic hydrocarbons.
