Municipal solid waste (MSW) represents an abundant feedstock for renewable energy production, offering simultaneous benefits in waste reduction and fuel generation. This study investigates catalytic pyrolysis using modified zeolite-based catalysts to convert MSW into high-quality bio-oils suitable for transportation fuels. Feedstock was pre-sorted and thermally pretreated to enhance conversion efficiency. Catalysts doped with nickel and cerium improved deoxygenation and aromatic stabilization, yielding bio-oils with significantly reduced acidity and enhanced calorific value. The optimized process produced a 48% liquid bio-oil yield, with 80% of hydrocarbon chains suitable for refinery upgrading. Gas-phase products were captured for heat recovery, improving total energy efficiency. Environmental analysis indicated reduced carbon emissions alongside lower landfill dependency. The results demonstrate that catalytic waste-to-energy pathways can contribute substantially to urban sustainability initiatives.
