Contaminates in slag and gases created during plasma utilization with elements such as mercury, cadmium, sulphur, SO2, HCL, dioxins, selenium, chromium, lead, barium, arsenic, radioactive elements are strictly controlled by usage of special water or dry scrubbers and filters. Using this method elements are considerably minimized below environmental standards. The remainder of the pollutants sink into glassy slag and can be treated further in close system, which is a major distinction to conventional incineration.
