In an interview with CNN, McCartney claims that because of their special formula, the roads they produce are 60% stronger than traditional roads. He also noted that the lab tests they ran project that the roads made from their product may last up to three times longer than regular ones.“We went through about five to six hundred different designs of different polymers that we were mixing in before we found one that actually worked,” he said. “At the end of the day, plastic is a great product,” he says. “It lasts for long, which is a problem if it’s a waste product, but not a problem if we want it to last,” McCartney concluded.
