A method in which a plasma arc torch (16) is used to vitrify and remediate a site containing municipal waste (12), contaminated soils, resulting from a hazardous material deposit or spill, or contaminated buried objects. The process steps of a first preferred embodiment involve drilling a series of holes into the waste material mass at proper spacing, inserting and operating a plasma arc torch (16) 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 (36) is produced and collected in a hood which is attached to scrubbing and chemical cleaning apparatus (38). The resultant gases are commercially useful as fuel gas and the vitrified residue (14) is significantly smaller in volume than the original waste material volume, thus substantially extending the useful life of the landfill sites and ultimately providing a firm foundation for construction. |
