Soil vitrification

Also gaining acceptance as alternative routes for immobilizing metals are processes such as soil vitrification, and the addition of cement-like (pozzolonic) agents whereby undesirable soil components are entrapped in a vitrified matrix. Vitrification of radioactive waste materials is currently being used as well. Examples of vitrifying media include borosilicate glasses and iron phosphates. Whether a specific vitrification process is chemical or physical in nature is not always clear. Table 10.2 lists the main selection criteria for this application. [Pg.256]

Rotary kilns, as described previously, can be used to incinerate materials which can be excavated and fed into the kiln. Vitrification is a process which can be used without removing the soil and is described below. [Pg.166]

Thermal processes like pyrolysis use heat to increase the volatility (separation) to burn, decompose, or detonate (destruction) or to melt (immobilization) contaminants in soil. Separation technologies include thermal desorption and hot gas decontamination. Destruction technologies include incineration, open bum/open detonation, and pyrolysis. Vitrification is used to immobilize inorganic compounds and to destroy some organic materials. In contrast, pyrolysis transforms... [Pg.157]

Recalcitrant organic contaminants in the unsaturated zone, those that are difficult to remediate by vapor extraction, biodegradation, or other biological-chemical processes, can be removed via vitrification and electrical heating. This process involves heating the soil by electrical resistance or applied electrical fields to vaporize semi-volatile and volatile compounds, thermally to break down larger organic molecules, and (if heated sufficiently) to vitrify the mineral matter in the soil.
