Abstract In order to get renewable energy from plastic waste, it should find a pathway or create a new composite that is thermally stable, non-toxic, environmentally inexpensive, and highly efficient. Thus, in our research, we work with composite materials that provide a hetero catalyst designed to crack Polyethylene high Density ( PEHD) , which is composed of Metals (Mn, Ag) in Nano scales , and Graphene impregnated inside the PEG matrix. In order to evaluate fabricated composite catalyst, to be applicable on conversion plastic polyethylene high density to gases yields and solid char carbon using pyrolysis and gasification reaction . the process were carried out inside the fixed bed reactor. Various characteristics have been conducted for final products (gases and black char), further spectroscopic analyses like Ultraviolet–visible spectroscopy (UV) , Cyclic voltammetry (CV) , Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD ), and Thermogravimetric analysis (TGA) were investigated for the new composite.
