The Treatment of Used Reagent Glass Bottles Using Solidification Technology

Abstract

Used reagent glass bottles are solid waste that people rarely pay attention to in Indonesia. In many cases, the bottles are disposed off without proper handling and treatment, due to the lack of research and information. One potential treatment for such waste is to transform the glass bottles into raw materials for concretes. The objective of the research is to determine the influence of crushed glass particles to the quality of the concrete. The potential reduction of glass bottles will also be calculated.The glass bottles used in this research are the amber ones. The concrete was designed to meet the K225 type requirements. Experiments were done using 0%, 25%, 50%, and 75% of crushed glass particles. In the concrete production, these crushed glass particles will replace the coarse aggregates. This research measured compressive strength and Toxicity Characteristic Leaching Procedures (TCLP) tests in accordance to SNI and TCLP Extraction Procedures from BAPEDAL. At the end, it was found that the concretes using all variations meet the requirements. As for the TCLP, it showed that concentrations of Cr6+ for the concretes using all variations were all under the threshold, according to Hazardous National Regulation 101/2014. The potential reduction is 600 - 2100 waste bottles.
