This study investigates a novel integrated system combining waste management and sustainable energy production through co-gasification of municipal solid waste (MSW) blends with various feedstocks: paper mill sludge, plastic waste, and food waste. Techno-economic assessment of producing value-added products while minimizing carbon emissions through syngas generation and subsequent conversion to biofuels. The process analysis evaluates syngas composition under varying steam-to-biomass ratios and gasifier temperatures (500–1200 °C), achieving optimal H₂ yields with MSW-food waste blends. Cryogenic separation utilized for high CO₂ capture efficiency (95%+) with purities reaching 0.9979, particularly effective for MSW-food waste feedstock.
