A mini assessment and study of the Compactibility of different pozzolonic materials for stabilization of different waste

摘要

Disposal of solid and hazardous wastes has become a major issue in all industrialized process. These wastes may pose a potential hazard to the human health or the environment (soil, air, water) when improperly treated, stored, transported or disposed off or managed. Solidification/Stabilization (S/S) is one of the proven technologies that involve mixing the waste with a binder to reduce the leachability, for safe disposal. In the present study the hazardous waste which comes from Metal, Automobile and Steel Industry were stabilized with combinations of different binder in common ratio along with waste. The Stabilized Samples thus prepared, were tested for Toxicity Characteristics Leaching Procedure (TCLP). Leaching results indicated that stabilization technique was effective in terms of restraining of leaching of heavy metal ions like Zn, Mn, Ni and Pb. Metals and Automobile industrial waste were stabilized more effectively by common ratios of binders. Steel industrial waste also gets stabilized but the effective ratio of binders was different from the other two industries. This paper focuses on usability of multi-additive to support better fixation to ensure compliance with existing regulatory standards.
