Currently, steam plasma gasification systems for recycling of waste polymers are among the most technologically advanced in the world. They provide environmentally friendly and simple processes for converting waste polymeric materials into a commercially valuable raw material, the so-called synthetic gas for use as a fuel or in the petroleum chemical industry. Using a steam plasma gasification system, PE, as a model compound, has been completely decomposed and converted into low-molecular-weight gases, domi-nantly carbon monoxide and hydrogen. The yields of these valuable gas products obtained through gasification increased upon increasing the temperature in the secondary gasification reactor and upon dereasing the steam-PE ratio. Product gases were obtained containing 65% of H2 and 30% of CO under the conditions of a steam-PE ratio of 1.2 and a temperature of 1200 C in the second gasification reactor, respectively. The operation of a V-type plasma torch is stable and reliable within the necessary range of parameters.
