Hazardous waste cleanup projects often require toxic waste destruction technology. ARI Technologies' patented process involves mixing the contaminated material with proprietary demineralizing agents and then heating the waste in a rotary hearth furnace. The ARI process is similar to vitrification but does not involve complete melting. Instead, the process results in sintering of the material. This sintering process is robust and very effective on a wide variety of waste types and contaminants. The process is also effective on other types of waste including demolition debris and predominantly organic waste.

Thermochemical treatment results in permanent destruction of organic materials. The presence of the demineralizing agents accelerates molecular diffusion in inorganic waste during heating. This molecular diffusion results in destruction of inorganic compounds such as asbestos and simultaneous oxidation and molecular bonding of metals and radionuclides within the waste media. This results in immobilization of metals and radionuclides. The process also results in significant volume reduction of the waste. Volume reduction is dependent upon the type of material being treated and can range from 10% for soils to over 90 percent for ACM or primarily organic materials.
