Case Study

PROJECT

Spon Lane

Client: Interserve / MPB Structures

Location: New Sandwell College, Spon Lane, West Bromwich, Birmingham

Contract Value: £550,000

Dunton Environmental uses Bio-accelerator and Regener8 technology to successfully convert 25,000 tonnes of contaminated waste soils into inert soils.

Challenge

  • The Development which was the construction of the new Sandwell College, West Bromwich, included a basement type excavation which would generate approximately 25,000 tonnes of waste soils contaminated with hydrocarbons and heavy metals.
  • The initial estimated costs for disposal off site were £1. 5 million.
  • Furthermore, given the nature of the site, long term stockpiling of soils and treatment were not feasible as this would have held up the overall development programme. Therefore, a solution was needed which could reduce a variety of contaminants in a very rapid timescale under restricted site conditions.

Conclusion –

  • All Dunton Environmental was involved at pre-contract design.
    The remediation strategy was integrated into the development advance works programme.
  • Proposals for utilisation of Dunton’s bio-accelerator and regener8 technologies for the degradation of the hydrocarbons and the heavy metals were presented to the Environment Agency for approval.
  • Works commenced and Dunton utilised their bio-accelerator technology to rapidly reduce the hydro-carbon contamination.
