Abstract [en]

Construction is associated with quarrying as well as heavy transportation of soil and rock materials, in and out of construction sites. Both quarrying and transportation of the excavated materials result in negative environmental impact due to energy use and greenhouse gas (GHG) emissions. Moreover, soil and rock materials of suitable geotechnical quality for construction are a scarce natural resource in some urban regions. These issues have urged the need to optimize the use of quarry materials on-site and thereby reduce transportation. Still, internal flows of soil and rock materials in urban areas have not been well analyzed. This study presents a model to analyze future soil and rock flows in terms of material quality and quantities in urban areas. Furthermore, the study analyses the possibility of recycling excavated soil and rock and thereby reduce transportation and transport-related GHG emissions. The study applies the model to analyze as a case study integrating future residential and non-residential developments and a highway project. The case study revealed that excavated material would be generated in enough volumes to potentially cover the quarry materials demanded for providing stability and permeability to buildings, streets and highway. The scenario analysis showed that provision of strategically located recycling sites for material coordination could reduce the demand for soil and rock transportation as well as transport-related GHG emissions i.e. by 23 – 36 % per area, compared to a business as usual scenario. The study shows that internal soil and rock flows within regions can be modelled by using data from development plans and geological maps. The model results may serve as a basis for decision making regarding strategic material management in urban planning.

Abstract [en]

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.

Abstract [fr]

Le transport maritime est en augmentation en raison de ses avantages environnementaux et économiques. L’expansion des ports que cela implique et l’évolution vers des navires plus longs, plus larges et à plus fort tirant d’eau provoquent un énorme besoin de dragage des sédiments dans les chenaux et les ports. Une proportion importante de ces sédiments est contaminée par des métaux lourds et des polluants organiques. Des millions de mètre cubes de ces sédiments devront être dragués et pris en charges dans les années à venir, selon les études réalisées par le réseau SMOCS/PortInfra. Le projet SMOCS (Gestion durable des sédiments contaminés), faisant parti du programme régional de la mer Baltique 2007-2013, a élaboré des recommandations sur la gestion des sédiments contaminés basées sur une approche de développement durable. Cet article traite des considérations importantes et des expériences clés des phases successives d’un projet, de la caractérisation des sédiments à draguer, en passant par l’évaluation des risques, l’étude de faisabilité et la sélection des options de gestion, la planification et les demandes d’autorisations, jusqu’à l’exécution incluant les détails de conception, les essais pilotes et les mesures d’entretien incluant la surveillance. La technologie de stabilisation / solidification a été appliquée ce qui a conduit à l’utilisation efficace de sédiments contaminés traités dans les constructions portuaires en réduisant l’utilisation de ressources naturelles finies.

Abstract [en]

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.
