TRANSFORMATION OF the former Dinnington Colliery site near Rotherham (GE October 04) won a Green Apple Environment Award for 'National Green Champion' at the end of last year.
The award, presented to project owner Renaissance South Yorkshire at The House of Commons on behalf of the Green Organisation, recognises the project's use of bioremediation.
Before clean up the site had extensive deposits of colliery spoil, much of it containing hydrocarbon-based coke-works waste. Some 700,000m 3of ground on the site was excavated, tested and re-used, with 30,000m 3being cleaned through bioremediation.
Consultant Scott Wilson head of land contamination David Cragg said: 'We needed to keep tight control of all information concerning the location of the materials and test results - both at the point of extraction and where redeposited in the finished final works.' Scott Wilson designed the overall redevelopment for Renaissance South Yorkshire. Main contractor was Birse Civils, with the bioremediation subcontracted to WSP Remediation.
