Efforts and Issues surrounding Revitalizing Recycling of Construction Sludge

Abstract

There are still some cases of inappropriate mud recycling on the utilization of construction sludge. The main reasons for this are that the line between construction sludge and soil generated from construction is blurred and its treatment as waste is usually disregarded. Also, recycling designs that provide sufficient attention to ensuring product quality have not yet been implemented. In other words, when recycling construction sludge, it is essential to take initiatives based on waste/recycling governance, to strictly apply reproduction methods, and to properly evaluate costs. In order to plan and implement a construction sludge recycling plan, the establishment of applicability standards which include applicable laws and regulations/environmental standards is necessary, along with the proper selection of treatment technologies, construction systems, and quality control methods that fully take these standards into consideration. In this paper, some examples of projects and issues surrounding the activation of construction sludge recycling are introduced.
