Carbon dioxide-free asphalt could reduce Sweden´s emissions by one percent
Asphalt is traditionally heated using energy from fossil fuels, and asphalt handling accounts for one percent of Sweden's carbon dioxide emissions. A new project named SMMART (Swedish Magnetite Microwave Asphalt Road Technology) will develop a microwave-based technology for heating asphalt and adding magnetite to the asphalt mix. This allows the heating process to be powered by renewable energy rather than fossil fuels. The innovative project not only focuses on reducing emissions but also looks to drive work on health and safety issues to create a climate-smart, profitable solution in an
