COMPANY TURNS PLASTIC
 BOTTLES INTO ROADS 

G'day folks,

Most people nowadays recognize the problem that is plastic pollution and many are finding ways to fight it. From reducing personal plastic use to banning single-use plastic straws, both civilians and governments are trying to fight the ever-growing amount of waste we produce. Waste that can take thousands of years to break down. One of the people who’s taken a pro-active role in this fight is Toby McCartney, an engineer who seemingly found just the perfect use for plastic waste.




The Scottish man was inspired by two things. First, he said that his daughter’s concerns over large amounts of plastic in the oceans were something that touched him deeply as he realized that his child shouldn’t grow up in a world where the image of the beautiful sea would be tainted by plastic waste. Secondly, while on a trip to India, McCartney noticed local people melt plastic waste to fill potholes on their roads. That gave him an idea to start a company.

“The idea was born when our CEO, Toby McCartney, was working in Southern India with a charity helping people who work on landfill sites as ‘pickers.’ Their job is to gather potentially reusable items and sell them to be turned from rubbish into something useful again.




Some of the waste plastics retrieved by the pickers were put into potholes, diesel poured all over them, and the rubbish set alight until the plastics melted into the craters to form a makeshift plastic pothole filler.”

However, McCartney quickly realized that councils in the UK wouldn’t be too happy about the idea of burning plastic and diesel, so he had to find a better way to execute the idea. Toby got together with his friends, Gordon Reid and Nick Burnett, to launch MacRebur in April 2016—the name being based on part of each of their surnames. From there, they started developing a technique and formula to achieve their goal—use plastic waste for road construction.




They take plastic from commercial and household use (the split is about 60 percent commercial and 40 percent household) and use a granulator to turn it into small pieces of no more than 5mm.  “Next, the plastic granules are mixed with our activator—it’s this that makes the plastic bind properly into our roads. Our activator is patented and what’s in it is a secret! This blend of plastic granules and the activator—let’s call it the MacRebur mix—then goes to an asphalt producer.”




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.



Clancy's comment: Excellent. There should be more of this around the globe.
