Treatability Trial for Stabilization of Dry Flux Waste with High Leaching of Boron *)

The aim of this trial was to determine the ratio of stabilization prescription to treat dry flux waste generated from a musical instrument manufacturer which leached out high level of boron, i.e. 1301 ppm; while the limit is only 500 ppm according to the Indonesian environmental regulations. Stabilization is required in response to the regulations which restrict specific categories of waste from hazardous waste landfills unless the wastes are pretreated to a minimum leachibility standard. The intent is to reduce the leachibility of hazardous constituents as measured by the TCLP. Stabilization process is effective in treating a variety of difficult to manage waste materials for reuse or disposal. This method has been identified as the Best Demonstrated Available Technology (BDAT) for treating a wide range of Resource Conservation and Recovery Act (RCRA) non-wastewater hazardous waste categories. From the trial, it was obtained that this flux waste can be stabilized using prescription comprised of sand, lime, fly ash and Portland cement with ratios of 0,5, 1,5, 01,5 and 0,1 (w/w) respectively.

Keywords: hazardous waste, stabilization, flux, leaching.
