Use of Dredged Material in Solid Waste Management.

摘要

This report presents the results from an investigation of the feasibility of using dredged material in solid waste management. Potential uses investigated included the construction of cover, liners, gas vents, leachate drains, and gas barriers at sanitary landfills. The properties of dewatered dredged material were compared with those of similar types of soil, and the suitability of dredged material to fulfill the functional requirements of various uses of soil at solid waste disposal operations was evaluated on the basis of the comparison. The suitability of slurry or semisolid dredged material was also evaluated. This report discusses the environmental and economic factors that will influence the feasibility of using dredged material in solid waste management. How the different uses for dredged material can be coordinated with dredged material and solid waste disposal operations occurring simultaneously or sequentially at the same location are also discussed. Concepts are presented to suggests the types of operations that could result if dredged material were used in solid waste management. The investigation concluded that dewatered dredged material can meet the functional requirements of several uses for soil at a sanitary landfill, that uses for semisolid dredged material are limited to situations in which trafficability is not a consideration, and that trench and area methods of sanitary landfilling are adaptable to the use of dredged material.
