The solidification/stabilization of metals in hazardous waste has been implemented at remediation sites for more than 20 years. Solidification/stabilization is a viable tool for processing of various wastes, hazardous or nonhazardous, from commercial and industrial operations or historic sites with residue in contaminated media such as soil or water. The main objective of the project is to optimize the mix of binders and nonconventional mix of additive materials for stabilization of the two

Efficiency of the mobilization depends on parameters such1as curing time, dosage of stabilizer and combination of stabilizer to reach the criteria of hazardous waste and safe disposal of this waste into the landfill. infectious characteristics causing risk to wellbeing or environment, regardless of whether alone or when in contact with different wastes or environment". The present study gives information about optimization of the stabilizer mixes for the solidification of the two given metal-laden sludge and to to arrive at a new unconventional partial substitute for the conventional binder (cement) using waste substances, for the solidification-stabilization process. A major task to manage hazardous waste is to stop the leaching of the disposed waste from polluting the underlying ground water. Of all the above mentioned options for management of hazardous waste, this project focuses on treatment/stabilization of hazardous wastes prior to disposal into a landfill, with addition of cement binders, fly ash, lime and sinter.
