The escalating demand for plastic presents an immense peril to both the environment and humanity. Not only have there

been notable advancements in the creation of advanced biodegradable polymers, but there has also been a lack of attention

towards tackling the current issue of plastic waste. Processing fuels via plastic waste valorization provides a feasible approach

to recycle plastics and mitigating pollution for the improvement of society. This review addresses a comprehensive analysis

of various heterogeneous catalysts in the context of plastic pyrolysis to produce fuel, intending to identify an eco-friendly

method for recycling garbage. The choice of catalyst has a substantial eff ect on the disintegration process of waste plastic,

dictating the properties of the resulting fuel, encompassing both the amount and the quality. Pyrolysis, an alternative method

for addressing the increasing waste disposal issue, is a non-toxic process that does not release hazardous pollutants, in contrast

to incineration. The waste plastic serves as a feedstock for pyrolysis process, employing innovative, environmentally

friendly catalysts derived from natural and other sources, to generate fuel oil that possesses similar physical characteristics

to the diminishing petroleum-based fuels. This critical review analyzes the impact of diff erent heterogeneous catalysts on

the process of transforming waste plastic to produce fuel through pyrolysis. Heterogeneous catalysts are crucial to the process

of turning discarded plastics into oil, off ering signifi cant potential for improving not only economic and environmental

conditions but also benefi ting both industry and society.
