With the booming of economy, consumption of electronic products have increased rapidly and so do the generation rate of electronic waste. A common type of electronic waste in the final stage at recycling facilities is polyurethane. Polyurethane could be utilized as valuable fuel, since it has higher heating value and low hazardous contents. Gasification experiment was conducted on pellet type SRF made of polyurethane at 1000℃ using a fixed bed reactor. One of the final product in gasification experiment is bottom ash, which usually discarded on landfill. In this study, we tried to figure out the characteristics of bottom ash, which will enable us to know about the recycling possibilities of this residue.
