Title: A holistic life cycle analysis of waste management scenarios at increasing source segregation intensity: The case of an Italian urban area

Highlights: • Waste management scenarios starting from different SS intensity were analyzed by LCA. • Several experimental data were utilized for the inventory. • Collection activities influences marginally global impact. • Maximum global environmental gain was achieved by SRF for coke substitution. - Abstract: Life cycle analysis of several waste management scenarios for an Italian urban area was performed on the basis of different source segregation collection (SS) intensities from 0% up to 52%. Source segregated waste was recycled and or/recovered by composting. Residual waste management options were by landfilling, incineration with energy recovery or solid recovered fuel (SRF) production to substitute for coal. The increase in fuel and materials consumption due to increase in SS had negligible influence on the environmental impact of the system. Recycling operations such as incineration and SRF were always advantageous for impact reduction. There was lower impact for an SS of 52% even though the difference with the SS intensity of 35% was quite limited, about 15%. In all the configurations analyzed, the best environmental performance was achieved for the management system producing SRF by the biodrying process.
