An apparatus having a thermal scission reactor with a graphite-lined plasma arc chamber for the pyrolytic disposal of toxic or hazardous waste. The thermal scission reactor includes a vessel with the plasma arc chamber surrounded by a water jacket. A tubular plasma arc electrode is provided for reciprocating movement within the plasma arc chamber. A conduit communicates with the tubular plasma arc electrode for the introduction of waste material through the tubular plasma arc electrode into the plasma arc chamber. The tubular plasma arc and an opposing electrode produce a plasma electric arc within the plasma arc chamber. An entry duct communicates with the plasma arc chamber for introduction of solid waste into the plasma arc chamber. An exit duct communicates with the plasma arc chamber for escape of gases and ash from the plasma arc chamber. Graphite liners are provided in the plasma arc chamber, the entry duct and the exit duct. The graphite liners may be impregnated with substances for neutralizing the waste material being processed. Injection ports for introduction of neutralizing agents, water, oxygen or hydrogen into the plasma arc chamber may be provided.
