GO GREEN WITH COLAS

Needless to say, the further the reduction in mixing temperatures, the greater the savings in energy use at the asphalt mixing plant and, as a consequence, the greater the reduction in greenhouse gas emissions. It has been widely reported in the literature that energy savings of the order 15 to 20 % can be achieved when the mixing temperatures are reduced by 30 to 40 °C. In Ireland's case, as we manufacture approximately 3 million tonnes of hot-mix asphalt per year, this would equate to a reduction in carbon emissions of the order 15,000 tonnes of CO2 eq. per annum...
