Metallic-resin compounds fuel processing process

In a demonstration plant for the recycling of post-use electric home appliances, the authors developed a metal-resin compounds fuel processing system for generated plastics and shredder dusts from this recycling plant. In this system, waste plastics and other shredder dust is thermally cracked in an oxygen-free rotary carbonization reactor with a maximum rate of 250 kg/h. Most of the plastic is gasified and then cooled to create fuel oil, which is recovered and used to heat the reactor. Some metallic material, along with carbon, is discharged from the reactor as residue and goes through final recycling at an external nonferrous smelter. Water used to clean the gas and fuel oil in this process is treated and reused in a closed system. In this process, plastics that contain small amount of metals are continuously carbonized in the rotary kiln type reactor
