Assessment of Co-Gasification of Municipal Solid Waste and Torrefied Urban Forest Waste: A Life Cycle Assessment Perspective
Short Introductive summary
This study conducts a comprehensive analysis of co-gasification involving hybrid blends of municipal solid waste (MSW) and torrefied urban forest waste (UFW) in BrasÃlia, Brazil. Using experimental data from torrefaction treatment and a thermodynamic equilibrium model, two syngas production scenarios are examined: hydrogen-rich gas and enhanced calorific value gas. The research optimizes conditions based on torrefaction treatment effects, varied hybrid blend compositions, and gasification mediums. Employing Life Cycle Assessment (LCA) via GaBi software, the study identifies primary environmental impacts, emphasizing Global Warming Potential (GWP) and Photochemical Ozone Formation Potential (POCP). Notably, Scenario (i) displays lower GWP impacts than Scenario (ii), underlining the need for comprehensive considerations in waste management decisions.
