Abstract
The process of the present invention serves to remediate and reduce the volume of waste materials in a landfill site and increases the useful life of the treated landfill. The process steps involve drilling a series of holes into the waste material mass at proper spacing, inserting and operating a plasma arc torch in each drilled hole to pyrolize, remediate and vitrify the waste materials and allowing the melted materials to cool and harden. During the process, a gaseous by-product is produced and collected in a hood which is attached to scrubbing and chemical cleaning apparatus. The resultant gases are commercially useful as fuel gas and the vitrified residue is significantly smaller in volume than the original waste material volume, thus substantially extending the useful life of the landfill site and ultimately providing a firm foundation for construction.
