Converting plastic waste into fuel through thermal and catalytic processes presents a promising approach to managing this waste while generating valuable energy resources. Thermal techniques such as pyrolysis involve decomposing plastic polymers at high temperatures in an oxygen-free environment to produce liquid fuels, gases, and char. The liquid fuel, often referred to as pyrolysis oil, can be refined and used as a substitute for conventional diesel or gasoline. Catalytic conversion enhances pyrolysis by introducing catalysts that lower reaction temperatures and improve product selectivity. Catalysts such as zeolites, metal oxides, and nanomaterials accelerate breakdown reactions and help produce fuels with better quality and reduced contaminants. These technologies not only reduce landfill waste and environmental pollution but also contribute to circular economy principles by recovering energy from non-recyclable plastics. Integrating plastic-to-fuel processes within existing refinery infrastructures can facilitate smooth adoption and increase economic viability. Challenges include controlling emissions from the conversion process, managing by-products, and ensuring the consistent quality of feedstock plastics. Nevertheless, ongoing research and pilot-scale projects are addressing these issues, paving the way for industrial-scale implementation. Plastic waste recycling into fuel aligns with global efforts to reduce plastic pollution, mitigate greenhouse gas emissions, and promote sustainable industrial innovation. It exemplifies a practical solution at the intersection of waste management and clean energy transition.<br /><br />"Al-Mustaqbal University – The No. 1 Private University in Iraq"<br /><br />
