The increa.ing consumption of pla.tics inevita.ly results in increa.ing a.ounts of wa.te pla.tics. Beca.se of their long degra.a.ion periods, these wa.tes nega.ively a.fect the na.ura. environment. Numerous studies ha.e been conducted to recycle a.d elimina.e wa.te pla.tics. The potentia. for recycling wa.te pla.tics in the iron a.d steel industry ha. been underestima.ed; the high C a.d H contents of pla.tics ma. ma.e them suita.le a. a.terna.ive reducta.ts in the reduction process of iron ore. This study a.ms to substitute pla.tic wa.tes for coa. in reduction melting process a.d to investiga.e their performa.ce during reduction a. high tempera.ure. We used a.common type of wa.te pla.tic, polyethylene terephtha.a.e （PET）, beca.se of its high ca.bon a.d hydrogen contents. Composite pellets conta.ning PET wa.tes, coke, a.d ma.netite iron ore were reduced a. selected tempera.ures of 1400 a.d 1450℃ for reduction time from 2 to 10 min to investiga.e the reduction melting beha.ior of these pellets. The results showed tha. a. increa.ed tempera.ure a.d reduction time increa.ed the reduction ra.io of the pellets. The optimum experimenta. conditions for obta.ning meta.lic iron （iron nuggets） were reduction a. 1450℃ for 10 min using composite pellets conta.ning 60% PET a.d 40% coke.
