Abstract

Sustainability is becoming a very important issue in contaminated land remediation and should form one of the factors used in future selection of treatment technologies. In situ stabilisation/solidification (S/S) is a remediation technique that is increasingly being applied to the treatment of contaminated sites because of numerous advantages over other remediation techniques. This paper assesses and compares aspects of the technical sustainability of in situ S/S with landfilling. Criteria previously established for the assessment of the technical sustainability of the remediation of contaminated land are employed. The comparison is presented in the form of a case study based on a real remediation project in the UK. The analysis indicated that landfilling had a larger impact than S/S in the majority of areas investigated, such as waste production (1000kg waste/t soil remediated for landfilling compared to none for S/S), transportation (12. 9km/t for landfilling, 0. 4km/t for S/S) and use of raw materials (1005. 5kg/t for landfilling, 88. 9kg/t for S/S), although S/S had high greenhouse gas emissions (12. 6kg/t for landfilling, 40. 9kg/t for S/S). In addition, a multi-criteria/cost-effectiveness analysis gave cost effectiveness scores of −34. 2 to S/S and −138. 1 to landfill (where more positive is better). [Copyright &y& Elsevier]
