Some asphalt waste contains a material known as Coal Tar this is used as a binder in previous road construction prior to the introduction to the construction process of Bitumen. Coal Tar is deemed an hazardous waste due to the elevated levels of PAH’s (Polycyclic Aromatic Hydrocarbons) some of which are carcinogenic. There has been a sharp rise in requests to help clients manage the hazardous waste that is generated from road maintenance and reconstruction activities with Coal Tar contained materials.

The Solution

Foambase® is an approved method of re-using such hazardous wastes that contains Coal Tar. This helps our clients to avoid the high disposal costs and preventing the waste from having to be transported safely to one of very few permitted landfill sites, which due to their scarcity, are extremely expensive and difficult to access, so involve high transport costs.

As the Foambase® process is cold, it doesn’t give rise to the aromatics. It also binds the contaminants within the product, which is approved for reuse in surfacing applications.

All the relevant permits and licenses to treat these wastes either at our depots or on a national contract basis where we can move the processing module to the client’s job site.
