ICV melts have their downsides as well. The most immediate concern of ICV melts is the cost. ICV requires a treatment facility, meaning either a new facility must be built or an existing facility must be renovated to accommodate the new process. Both methods require considerable capital investment. Even after the facility is prepared for the process, ICV melts cost about $1,585 per ton of processed waste (3-4 times the cost of an SPV melt). This extra cost is due to the necessary safety precautions in the facility. For example, the melting process occurs at very high (1200 to 2000 °C) temperatures, and some of this heat is dispersed throughout the facility; so adequate cooling and ventilation are needed for areas where workers are present.
