Today, the world is suffering from serious problems like, climate change, green gases, and increasing temperature degrees on earth which is strongly connected with the plastic waste problem. in that work, we reached out to fabricate heterogeneous catalyst (mainly green materials synthesis) composed of a bunch of ceramic composites (vanadium oxide, and Sliver NPS) assembled on a thin layer of zeolite. Various characterization had been carried out on fabricated composite like surface morphology TEM, XRD, and Uv to evaluate prepared catalyst. Then novel composite catalyst has been applied it be applied to the degradation process of High-density polyethylene (HDPE) throughout the Gasification process in the fixed bad reactor. In order to apply to the catalyst, it has to build an optimization gasification system (Temperature, heating rate, reaction time, and catalyst loading ratio). Regarding results of final products (gas yield ratio, and solid char), the best-optimized parameters with highly efficient catalytic are used thermos cracking of PEHD is % 0.2 wt at temperature 650 OC for 1 hour. We observed Composite has a great effect on gases yields products, and solid waste char. For instance, in the existence of composite catalyst, the gases ratio methane, and Hydrogen is more than in absence of a catalyst. Another characterization had been performed on composites and final products such as SEM, GC, and EDX.
