This article describes a disposal method for two types of waste in a plasma reactor operating in a dependent connection, and the subsequent transformation of such waste into a vitrified glassy slag. Those two wastes are asbestos-cement roofing material and the fly ash from fluidized bed boilers. The first waste falls into the category of hazardous waste and the latter one in the category of so-called non-hazardous waste. In the Slovak Republic, both types of waste are currently disposed of through landfilling. Deficiencies related to landfilling waste are sorted through plasma melting technology in stationary and mobile modes. Achieving an inert product after the combined plasma melting of the mentioned waste is attained through the correct mix ratio and temperature. The high temperatures reached in the reaction chamber of the plasma reactor (up to 1,400ºC) guarantee the recrystallization of the chrysotile fibers represented in the asbestoscement roofing materials and their transformation into a glass matrix of the emerging products, creating vitrified slag. This product is predominantly a stable slag oxide (a mixture of SiO2, CaO, Al2O3, and MgO). It forms at the bottom of the reactor, a liquid phase that, following a regulated cooling phase, possesses properties suitable for further use in the production of insulation materials and ceramic products.
