The observations from FESEM The structure of most char samples is spherical. The observations from FESEM imimages have been in agreement with Sharmaal. [45] and Sogancioglu et et al. [37]. The deages were in agreement with Sharma et et al. [45] and Sogancioglu al. [37]. The depolypolymerisation of merisation of wastewaste PP enhanced the temperature rise. C-600C-600 demonstrated PP enhanced with with all the temperature rise. demonstrated smaller smaller sized spherical particle size distribution in comparison with the other people. However, spherical particle size distribution when compared with the other people. However, the surface the surface of char samples revealed irregularity together with the increasing pyrolysis of char samples revealed irregularity as well as the rising pyrolysis temperature, temperature, which was associated with depolymerisation.
