“…These techniques are minimally destructive to the site and the costs of their use are lower compared to ex situ techniques. In situ vitrification has a number of advantages over other technologies, especially due to its ability to treat mixed waste, including soil with buried waste or tanks, dried sludge, tailings, sediments, organic waste, chemical waste, radioactive waste, and mixtures of hazardous and radioactive waste [16,19,22,25,35,36,47,51,55,[57][58][59][60][61][62][63][64]. The application of in situ techniques depends on the type of pollution, the conditions prevailing in the contaminated medium as well as the conditions prevailing at that location [20,21].…”
