- Sea transport is increasing due to its environmental and economic benefits. The related expansion of ports and the development towards longer, wider and more deep-draught ships cause a huge need for dredging of sediments in fairways and ports. A large volume of these sediments are contaminated with heavy metals and organic contaminants. Millions of m3 of these sediments have to be dredged and handled in the coming years according to studies performed by the SMOCS/PortInfra network. The SMOCS project (Sustainable Management of Contaminated Sediments) within the Baltic Sea Region Programme 2007-2013 has developed a guideline on management of contaminated sediments based on a sustainability approach. This paper deals with important considerations and key experiences in the different phases in a project from characterisation of sediments to be dredged, basic risk assessment, feasibility study and selection of handling options, planning and permitting, execution incl. detailed design considerations and field test and serviceability stage incl. monitoring. The stabilization/solidification technology has been applied implying the beneficial use of such treated dredged contaminated sediments in port constructions reducing the use of natural resources.

- Construction in developing urban areas implies use of construction materials from quarries and excavation of soil and rock. From a resource perspective, there could be benefits from using excavated soil and rock as a construction material. The aim of this paper is to describe the material flow and management practices of urban excavated soil and rock from the perspective of resource efficiency. A conceptual model for the urban flow of excavated soil and rock was developed and a literature review concerning the management of excavated soil and rock was conducted. The conceptual model was subsequently used to clarify the different perspectives of the scientific literature and knowledge gaps. Conclusions drawn are that there is little knowledge about the quantities and the fate of excavated soil and rock in urban regions. Current research is focusing on the waste flows of construction material and little is known about the overall management practices of excavated soil and rock. Clearly, excavated soil and rock are often disposed at landfills and the recycling rate for high quality purposes is low. There is a need to evaluate the potential for an increased use of excavated soil and rock as construction material. However, the overall efficiency of urban construction material management can only be evaluated and improved by also including construction materials produced in quarries.
