Abstract
It's not surprising that there's a significant amount of recycled waste in landfills and the environment, potentially containing harmful metals that can contaminate soil and water sources. However, utilizing recycled materials in construction can contribute to lower energy consumption. This research aims to examine the metal content (Iron, Copper, Zinc, Lead, Magnesium, and Cadmium) in recycled materials and identify those with safe metal compositions for construction purposes. The study employs the Toxicity Characteristic Leaching Procedure (TCLP) and Fourier Transform Infrared (FTIR) Spectroscopy to quantify metal and other chemical contents in Plastic, Fly Ash C, Sewerage Sludge Ash (SSA), and Slag. The extracted parameters will be compared to TCLP regulatory levels to ensure they contain safe metal amounts. The acid extraction fluid used had a pH level of 2.88 ± 0.05. Each test underwent three trials for metal analysis, and an average of three trails, following data rejection procedure, was accepted and used for the analysis. It is expected that "); border-bottom: 1px solid transparent; background-size: 3px; vertical-align: 0.235278px; line-height: 0px; position: relative;">all of the waste materials will be non-hazardous based on the TCLP tests and be suitable for use as construction materials.
