Abstract	The accumulation of waste plastics has become a major environmental concern due to their non-biodegradable nature and increasing consumption. Pyrolysis is an efficient thermochemical process that converts plastic waste into valuable liquid fuel under oxygen-deficient conditions. In this study, a laboratory-scale pyrolysis reactor was designed and fabricated to convert polyethylene-based waste plastics into crude liquid fuel. The reactor comprises a heating chamber, condenser, cooling coil, pressure gauge, and collection unit. Plastic waste was thermally decomposed at temperatures ranging from 350–500°C, producing hydrocarbon vapours that were condensed into liquid fuel. The developed system provides an economical and environmentally sustainable approach for plastic waste management while recovering energy from non-recyclable plastics. The study demonstrates the feasibility of producing alternative fuel through pyrolysis and highlights its potential for decentralized waste-to-energy applications.
