A Review of Beneficial Use and Management of Dredged Material

Abstract

This study systematically examined dredged materials from various aspects, including their sources, the volume generated annually, beneficial uses, and the management processes currently practiced. In addition, this paper presents the relevant policies governing the dredging, reuse, and disposal of dredged materials in the United States. A summary of various sources, types/classifications, and the physical and chemical properties of dredged materials used by various researchers are presented. This paper also summarizes the innovative techniques for the beneficial reuse of dredged materials in a wide range of applications in concrete materials, construction products, roadway construction, habitat building, landfill liner/cap, agriculture soil reconstruction, and beach nourishment. Further, limitations and corresponding solutions related to the beneficial use and management of dredged materials were provided in the end.

Reusing Dredged Material through Stabilization with So-Called Bio-Enzyme Products

“…Other management alternatives include disposal in landfills and the beneficial reuse of DM [9][10][11]. This later solution generates the most interest and has been the object of a recent extensive review [12]. However, DM generally makes for poor planting soils, may contain toxic compounds, and has limited structural properties, for example, shear strengths below 50 kPa (7.25 psi) and higher water contents than its liquid limits [13].…”
