Coal Tar Recycling
Certain asphalt waste contains coal tar which was used as a binder or sealant in past UK road construction in lieu of Bitumen. Coal Tar is deemed hazardous due to elevated levels of PAH’s (Polycyclic Aromatic Hydrocarbons) some of which are carcinogenic. The contractor encountered this on the Strensham Depot project.
To overcome this, they partnered with a regeneration company to recycle 1,500 tonnes of coal tar which would of otherwise have all been sent to landfill, saving the client approximately £50,000.
The are also reusing the same recycled coal tar for the base course, providing further environmental and commercial benefits. This saved 29.7 tonnes of carbon, equivalent to 36.5 direct flights from London to New York.
