The thermal decomposition kinetics of waste plastics through thermogravimetry with temperature programmed heating in Ar atmosphere was reported. Based on the experimental results, the kinetics parameters of some waste plastics were calculated. The results show that apparent active energies of selecting plastics are between 100.72～225.89 kJ/mol.

Simulating to the condition of iron powder production in Hoganas process, the reduction experiments of iron scrap were done by adding different kinds of typical chlorine free waste plastics in China into the scrap column. In this work, the influences of variety of waste plastics added and experiment temperature on the iron scrap reduction rates were studied by thermogravimetric analyses. Moreover, the remained pore canals made by the gasification of the waste plastics were investigated with microscopes. Furthermore, the effect of the remained pores in the column on the iron scrap reducing reaction between gas and solid phases was discussed.
