摘要：	In general, there’s a lack of disposal sites and/or alternative treatment techniques for beneficial reuse of contaminated dredged material in the Flemish region of Belgium. On the other hand there are several sites in this region that, due to former industrial activities, are contaminated and have no longer a commercial or industrial use or even have a negative value due to the present contamination and the needed sanitation before any further use. On top of this there’s an urgent shortage of industrial area in the Ghent region for the expansion of high technology oriented businesses and small to medium organizations. In the late nineties governmental organizations in the Ghent region were urgently seeking economical solutions for the disposal of contaminated dredged material. Several maintenance dredging operations were postponed due to a lack of disposal possibilities. Eventually several governmental organizations and private partners combined there expertise and developed the ‘Fasiver-project’ which includes the sanitation of a black-point (surface of about 7 ha) and the redesign of a 42 ha large site by means of a sludge treatment centre (dewatering lagoons) and a confined disposal facility for contaminated dredged material. The final destination of the site is industrial area (approximately 30 ha) and a greenbelt (approximately 10 ha) on top of the sanitised black-point. The profits made by the selling of the grounds in the industrial area shall cover the costs made for the sanitation of the black-point. The site is located in the Ghent region, on the crossing of highways E17 – E40 and the waterways Upper-Scheldt and a ring canal around Ghent. The installation and exploitation of the sludge treatment centre and the confined disposal facility are regulated and controlled by the Flemish Government. All necessary environmental and building permits are yet available. The design of the treatment centre and the confined disposal facility is in accordance with Flemish and European regulations, which means among other things that a double mineral liner or equivalent is installed at the bottom; several drainage layers are installed in order to collect the percolate and to control the impermeable liner; an isolating top layer minimizes environmental impacts in the future. After filling the disposal site the area shall be used as an industrial site. The total capacity of the confined disposal site is estimated to 1.3 million cubic meters.
