Life Cycle Inventory and assessment of the municipal solid waste management system: a case study in a municipality in southern Brazil
description: The present study conducted a Life Cycle Assessment evaluation of the Solid Waste Management System in Santa Cruz do Sul – RS, in order to provide background information and therefore support decision-making for future waste management scenarios. The software package named as Integrated Waste Management – 2, Version 2.5., was used to perform the LCA, where all inputs and waste management system outputs were identified and quantified. The conversion of the results from Life Cycle Inventory to Life Cycle Assessment in environmental impacts was carried out based on impact characterization factors from RECIPE 2008 version 1.08. The impact categories studied were: Photochemical Oxidant Formation Potential, Global Warming Potential, Acidification Potential, Eutrophication Potential, Depletion of the Ozone Layer Potential and Particulate Matter Formation Potential in addition to the Use of Energy and Final Solid Waste. The current waste management scenario has been simulated as baseline, considering three additional scenarios, which included raising the number of households served by selective collection, improvement of recycling recovery efficiency in the sorting stage and the introduction of the biological treatment stage into the system by composting the organic matter. The results showed that the current scenario is the most impacting, for global warming, with a total of 12,102,122.85 kg of emissions per year, whereas scenario 04 showed to represent the lowest contribution rates to environmental impacts in carbon footprint perspective (5,946,702.47 kg of emissions per year). The final disposal stage in landfills had also contributed significantly to environmental impact rates, followed by the waste collection scenario. The proposed changes, suggested by alternative scenarios, had demonstrate considerable environmental savings, hereby justifying the importance of implementing these strategies in waste management.
