The aim of this study is to determine the possibility of using recycled aggregates resulting from demolition and construction debris in the design of different layers of sanitary landfills instead of natural aggregates. This enables this research to be designed to avoid or minimize negative environmental impacts due to the emissions that are potentials threats that may adversely affect human beings, flora and fauna in coastal environment and estuaries.
This has been achieved by analysing the leachate resulting from recycled aggregates and comparing it with the leachate resulting from natural aggregates. Here we have implemented a number of columns made up of pvc (length of 1 meter and diameter of 8 inches). These columns have been divided into two groups, the first group consists of layers of waste and natural aggregates and the other consists of waste and recycled aggregates. After that we have compared the chemical parameters of leachate such as PH, BOD, COD, TSS and TOC between the columns groups described above and verified that the resulted values are among the permissible values. Finally, an evaluation has been carried out in terms of economic feasibility of using the recycled aggregates in the layers of landfills instead of natural aggregates
