South Baltic Guideline for the Application of Dredged Materials, Coal Combustion Products and Geosynthetics in Dike Construction

Dredged materials research has been developing rapidly during the past decade. Although sediments that are taken on shore are generally considered a waste according to European legislation, the materials prove to have a good potential to be recovered in a variety of applications. Anthropogenic materials, such as by-products of coal combustion (CCPs), generally fall under the waste law, too. Therefore, comparable hurdles have to be taken when it comes to the recovery of the materials. The European Waste Framework Directive demands a recovery rate for these secondary materials of 70 % by 2020. This implicates research and development in all fields of sediment management and material recovery. With a growing environmental awareness all around the Baltic Sea, many debates discuss strategies on how to reduce the amount of dredged sediments dumped at sea. In addition, many ideas are being developed how to increase the possibilities for CCP recovery beyond the standard road construction and concrete production applications. Here, it is of vital importance to address the particular characteristics of the different types of materials in an environmental context.
