The Canadian city of Vancouver is using innovative materials to pave its new roads: asphalt made up of wax from recycled plastic. The city is calling the asphalt mix a “warm mix” paving process, according to Fast Coexist. Using a warm mix, as Fast Coexist explains, allows asphalt to be “produced and transported at lower temperatures.” Using lower temperatures means that 20 percent less gas is used to heat the warm mix asphalt. Produced by GreenMantra Technologies, a Toronto-based company, the warm mix asphalt is made from 100 percent post-consumer recycled plastic waste.
