SP Energy Networks is undertaking a pioneering initiative to use recycled plastic waste to construct new roads at one of its substations.
SP Energy Networks has started to build new roads at its substation in Wishaw, North Lanarkshire, by using plastic waste collected on site. Work got underway this month and will be completed in sections over the next year. The new roads will be used to extend the site, as well as for the reconfiguration of the existing layout.
The plastic, which comes from general construction and domestic waste on site, will replace part of the bitumen – the sticky, black liquid that is traditionally used to make asphalt. To the naked eye, the roads will look the same as traditional versions but with far greater benefits for the environment.
It’s estimated that for every 100 square metres of road laid using waste plastic, the equivalent of over 435,000 single-use carrier bags or over 71,000 throwaway bottles are saved.
Steven McLagan, head of programme substations at SP Energy Networks, said: “We’re always looking for innovative ways we can be more environmentally friendly in our work at SP Energy Networks.
“This is the first time we’re using waste plastic to create roads at one of our sites and it’s exciting to be at the forefront of something which has so many benefits. We hope to roll it out across our projects and sites in the future.”
Protecting the environment is a priority for SP Energy Networks and it’s expected that two tonnes of plastic waste from the substation will be recycled for use in the new roads – more than the weight of an average mid-size car.
As well as offsetting the plastic waste collected on site, the plastic roads will deliver substantial environmental benefits by utilising waste that would otherwise have been burned or sent to landfill.
Experts also suggest that waste-plastic roads can be stronger, longer lasting and more flexible than standard asphalt.
The roads at Wishaw will use technology from Lockerbie-based waste plastic road specialists, MacRebur. The firm aims to help solve the plastic waste issue harming the planet and help to improve the quality of roads.
