Assessment of Technical Sustainability of Soil Remediation——A Case Study of in situ Solidification/Stabilization and off Site Landfill
土壤修复技术的可持续性评价——以原位稳定/固化技术和异位填埋技术为例

The sustainability of soil remediation is a key basis for assessing the sustainability of soil remediation engineering and selecting soil remediation techniques. This research took a contaminated site in Shanghai as a target, assessed the sustainability of two typical remediation techniques, in situ stabilization/solidification (SS) and off site landfill (SL), with the method of multi-criteria assessment (MCA). The results showed that S/S method was an economic option with less environmental pollution and better for sustainable development, while SL method was not only high in cost, but also emited more green gases, which was unsuitable for social sustainable development.
