报告内容简介：

The prevalent thermal treatment of municipal solid waste (MSW) in Singapore is incineration, which produces incineration bottom ash (IBA) as the treatment residue. The residue can potentially be used as aggregate substitute for construction applications. However, IBA has to be treated before safe usage. Long-term environmental behaviour of treated IBA (IBA-T) has not been monitored in local applications. This study serves to investigate such an application along Tanah Merah Coast Road where IBA-T will be used in the road base and sub-base layers.

The trial road will consist of three 50-m long sections built with IBA-T from different suppliers. A series of groundwater monitoring wells will be installed on the trial site to monitor and study the long-term environmental behaviour of the residue. Meanwhile, laboratory testing and modelling will be conducted to improve the overall understanding of the performance of the residue in actual operating environments. Specific emphasis will be placed on constructing a framework for the modelling and management of the residue. The specific tasks are: 1) establishment of a conceptual site model with risk assessment; 2) baseline site investigation; 3) groundwater and environmental monitoring for the trial site; and 4) laboratory tests. Based on the different activities introduced by the project, we aim to build a full spectrum of testing, monitoring, and modelling capabilities related to IBA-T applications in Singapore.
