AbstractThis paper reviews the sludge treatment and disposal operation in The Netherlands where the total volume of sludge is increasing and the sales potential is falling due to stringent quality requirements. The sludge can no longer be recycled to agriculture and has to be dumped on land. The techniques available for this purpose make sludge disposal much more expensive.A meticulous analysis of the entire sludge chain seems to be necessary to control the costs and minimize the environmental impact, and a start has recently been made on the formulation of ideas in this context.
