Tarmac recycles concrete on M5 contract
First publishedon www.AggBusiness.com
Tarmac delivered a major contract on the M5 motorway in the UK after recycling around 30,000tonnes of concrete and providing 8,000m³ of new concrete for new slipform central barrier works.
The project was part of an eight-week scheme to install nearly 13km of new concrete safety barrier, and some 30,000tonnes of concrete were excavated and then crushed into Type 1 and 6F5 aggregates at Tarmac’s recycling site in Ettingshall, Wolverhampton. Over 14,000tonnes of the recycled aggregates has already been deployed on local construction schemes.
Overnight works saw excavated material transported from the site, stockpiled locally, and reprocessed, with as many as 40 trucks bringing in around 1,700tonnes a night throughout the initiative.
Tarmac’s Stourport depot in the West Midlands supplied the concrete for the new barrier which was constructed by Extrudakerb.
“The local reuse of recycled materials is key to reducing waste to landfill and cutting carbon emissions through reduced transport movements,” says Nigel Blackburn, unit manager at Tarmac’s Ettingshall Recycling site in Wolverhampton.
“Managing materials in a more efficient way offers real scope to deliver efficiency and environmental savings.”
Tarmac says its delivery of the M5 contract supports the company-wide strategy around reducing waste to landfill and maximising the reuse of recycled aggregates.
Tarmac’s latest Sustainability Report reveals that, since 2004, the company has reduced waste to licensed disposal by 95%.
