Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal proce...

Recent difficulties in siting dredged material disposal facilities are increasing interests in alternative disposal or reuse of dredged material and the possible adverse consequences of any increases in the generation of dredged materials. This paper focuses on economic aspects of these issues. Simple methods are suggested for evaluating the economics of increasing or decreasing the rate of dis...
