  • Transportable, modular vitrification system for the treatment of waste material
    Patent number: 5611766
    Abstract: A system for the treatment of waste material includes a waste-receiving module for receiving waste material and blending it with glassmaking additives. The waste-receiving module is enclosed within a waste-receiving module container which is capable of being sealed for over the road transport so that the waste-receiving module can be transported safely from one source of waste material to another without complete decontamination. The system also includes a melter module containing a melter for melting together the blended waste material and glassmaking additives to form homogeneous molten glass and thereby stabilize the waste material. The molten glass is discharged to form a vitrified waste material. The melter module is comprised of one or more melter module containers which are capable of being sealed for over the road transport so that the melter module can be transported safely from one source of waste material to another without complete decontamination.
