This project presents the design and development of a Plastic Waste to Pyrolysis Conversion system — an innovative waste-to-energy solution. Plastic waste has become one of the most critical environmental challenges due to its non-biodegradable nature and widespread usage. The project focuses on converting plastic waste into pyrolysis oil through controlled thermal degradation in an oxygen-free environment. The obtained crude oil is further refined through fractional distillation and upgrading techniques to yield diesel-range fuel. Key processes include catalytic cracking and hydrotreatment to improve fuel quality. Testing of physical and chemical properties such as calorific value, viscosity, flash point, and density confirms the viability of the produced fuel as a sustainable alternative to conventional diesel.
