Vancouver, British Columbia, has developed a warm-mix paving process that converts recycled plastics such as milk jugs and yogurt containers into asphalt. The warm-mix asphalt is expected to help the city reduce its carbon dioxide emissions by 20%. "Safety-wise for the workers, it’s a lot better - and they’re finding added benefits in terms of longer life of the pavement as well, because you’re not heating the material quite as much," said Todd Strynadka of Terus Construction.
