TonerPave is made by adding MTP (Modified Toner Polymer) to standard asphalt. Every 1 tonne of MTP used replaces 600 kilograms of bitumen and 400 kilograms of fines (very fine dust). Carbon modelling has been done by ERM and Energetix  and the outcome shows that for every 1 tonne of MTP used, 0.27t CO2 greenhouse gases are saved from entering the atmosphere.
TonerPave is part of a range of asphalt products promoted by Downer as its ‘Low CO2 Asphalt’ range. These products reduce emissions by an average of 23%  compared to typical VicRoads baseline products. The average difference amounts to 14 kilograms of CO2 saved per tonne of asphalt.
