The use of rotary kiln incinerators significantly reduces environmental impact by ensuring complete combustion during the disposal process. With efficient burning at high temperatures, these systems minimize air pollution by reducing harmful emissions released into the atmosphere during traditional disposal methods like open burning or landfilling.
