A large number of wetlands have been created in the northwest part of Scania (south of Sweden) since 1991. Their types of construction vary, which affect their ability to remove nutrients from eutrophic watercourses. In this report, we have evaluated how different construction techniques affect nitrogen retention capacities andcompared cost-efficiencies between different wetlands. The wetlands […]

The aims of this article are to increase the awareness of sustainability as a tool to obtain more sustainable infrastructure and to show how sustainability may be calculated. The sustainability of an infrastructure may be assessed by using a set of indicators and a subsequent weighing process implemented on these indicators. Politicians should take part […]

The aim with this study has been to find a process which can recover aluminium from waterworks sludge. The separation processes used include acidification, ultrafiltration, nanofiltration and precipitation. The result of this study, which has been carried out over a period of three years, strongly indicates that it is technically possible to use acidification combined […]
