Licensed Treatment & Recycling Facility

New Wear Crossing, Sunderland

The Challenge

Our client was faced with the disposal of approximately 30,000 tonnes of hazardous dredge material from the River Wear. The materials were contaminated with various types of Asbestos, Hydrocarbons and Metals. The contaminants present limited the disposal options. Traditional disposal was prohibitively expensive as a result of a hazardous waste classification, and the moisture content of the dredge material meant that transport of the wet dredge was a major health and safety issue.

The Solution

ATG Group proposed an alternative three phase remediation program involving:

1. Stockpiling of dredge within a lined bund to allow for dewatering activities and treatment to reduce key contaminants and H&S risk

2. Transport of the materials to a waste treatment facility for further treatment

3. Stabilisation of the dredge material to produce an engineered product suitable for reuse

ATG Group’s method of off-site treatment and stabilisation was accepted and preferred by the Environment Agency
