The treatment of solidification/stabilization “s/s” is the treatment of dangerous wastes for disposal, reuse and/or site storage of land on contaminated. It is the technology that gain popularity because the regulation and profit potential. It often can be redeveloped after the treatment of waste can use on location of soil improvement for subsequent construction.
Solidification/stabilization (S/S) is a widely used treatment for the management/disposal of a broad range of contaminated materials and wastes; especially in those which is contaminated with substances classified as dangerous in the US. The process treatment involves mixing a binding material into the contaminated material and/ or waste. Such action objective of treatment is to protect men’s health and the living environment by immobilizing contaminated materials within the treated and controlled material. Immobilization within the treated and controlled material which will prevent migration of the contaminants to men as known, animals and plants. This type of treatment has been known to use treat radioactive wastes, since the 50s and hazardous waste since the 70’s. Fast forward to current time, the S/S continues as a cornerstone treatment technology for the management of radioactive waste, hazardous waste, and site preparation.
Government agency such as U.S. Environmental Protection Agency (EPA) identify S/S as a technology of established waste treatment. S/S is a main treatment technology for the waste management of industrial dangerous wastes. These wastes are regulated in the United States under the act of Resource Conservation and Recovery Act (RCRA). RCRA hazardous wastes are grouped into two classes: RCRA-listed and RCRA-characteristic. RCRA-listed hazardous wastes are wastes produced by industry that are generally known by the EPA to be hazardous. These wastes are “listed” in RCRA regulations and must be treated, stored, and disposed according to RCRA hazardous waste management regulations. RCRA-listed wastes destined for land disposal are required to be treated in order to reduce danger posed by the wastes after land disposal. RCRA-characteristic wastes are less routinely produced wastes that are found to be hazardous due to a characteristic of the waste. For RCRA-characteristic wastes, S/S can often be used to eliminate the danger characteristic. With the danger characteristic addressed the treated waste can be disposed at a lower cost or re-used.
