Steam gasification in the presence of carbonate compounds is an effective method to recover useful materials from the electronic waste, converting plastics into gaseous products that can be used for energy and allowing the expensive manual disassembly process to be avoided. We investigated steam gasification of polyimde film or other plastics in the presence of various mixtures of lithium carbonate, sodium carbonate, and potassium carbonate. The polyimde film was converted into hydrogen, carbon monoxide and carbon dioxide at 650℃ under 0.1MPa pressure in the presence of carbonate mixtures. Carbon dioxide was also derived from partial decomposition of the carbonates. Steam gasification was accelerated in the presence of various carbonate mixtures. These experimental results show that the steam gasification of polyimide or other plastics using various carbonate mixtures is one of the effective methods.
