A municipal solid waste information system, named W-MySir, is utilised to acquire high-quality data to implement an attributional life-cycle assessment (LCA) focused on the evolution of the environmental performances of municipal solid waste management in a specific area. The main aim was to investigate how this combined approach can be used for monitoring progress of the management scheme toward important targets, such as being CO2-neutral, increasing the circularity of the service, and planning a transparent approach to cost evaluation. The analysis was applied to the municipality of Procida, one of the three islands of Naples Bay (Italy), and focused on the last ten years of activity of the local solid waste service. The results of the life cycle impact assessment are reported in terms of the main impact categories. They indicate a positive evolution of the environmental performances, with improvements of up to 140% for global warming potential. The positive results are mainly due to the large increase in household source separation and separate collection in Procida during the period under analysis, together with the availability of a more integrated and sustainable regional system of solid waste management. Further improvements may be achieved through better performance at the sorting and remanufacturing stages of dry recyclable fractions and the availability of anaerobic digestion units to produce biomethane from organic fractions of municipal solid waste. The combined approach indicates potential further benefits for both the tools: LCAs could provide reliable results in shorter times; information systems could offer a wider spectrum of services for monitoring and planning waste management systems in a sustainable way. |
