Dataset Information

Dataset for life cycle assessment of pet bottle waste management options in Bauru, Brazil.

ABSTRACT: This paper contains a dataset and spreadsheet with the inventory, calculations and results for the Life Cycle Assessment of PET (polyethylene terephthalate) bottle waste management options in Bauru, Brazil. Data for the Life Cycle Inventory (LCI) was collected in situ at sorting cooperatives, through interviews with municipal authorities, and through literature review. Data analysis was performed using the SimaPro v8.0 software for assessment of environmental impacts, using the ReCiPe midpoint hierarchical method. The data and results contained in the spreadsheet are divided as follows: worksheet 1 provides a title page with the reference to this article; worksheet 2 provides the impact values for the impact categories considered; worksheet 3 presents the impact values for all collection and transportation fleets; worksheets 4 to 7 provide the impacts for each process and each stage (operation, emissions, and construction) for the case where: waste PET is disposed of in a landfill and the treated sludge is composted (worksheet 4); waste PET is incinerated (worksheet 5); waste PET is sent to sorting cooperatives and the reject is landfilled (worksheet 6); waste PET is sent to sorting cooperatives and the reject is incinerated (worksheet 7); worksheets 8 to 16 contain the impacts for each stage and the total impact for scenarios 1 to 9, which are combinations of the processes presented in worksheets 4 to 7, and the collection and transportation calculations for each scenario; worksheet 17 presents a summary of the net impact and the impact for each stage for all scenarios and all impact categories considered; worksheet 18 contains the impacts for each process and each stage for the case where waste PET is disposed of in a landfill, and the treated sludge is landfilled. The data in this paper are suitable for waste management researchers and professionals.

Project description:Municipal Solid Waste (MSW) management has been a long-standing problem for many cities in developing countries. Urbanization, population growth, and excessive demand for resources caused significant waste related environmental and socio-economic problems in cities. Integration of policy decisions with actionable targets and management of economic and environmental extremes were common challenges to achieving sustainable waste management strategy. Circular economy is a concept that has been evolved with sustainable resource management perspective adopted in this study to support scientific decision-making process for urban planners and policymakers. Life Cycle Assessment (LCA) is a framework to assess the environmental impacts of waste life cycle ranging from waste generation, transportation, treatment, and end disposal. This study used the LCA framework to evaluate the impact of MSW management of a selected local authority in Colombo, Sri Lanka, to identify the environmental impact of four (04) proposed scenarios in comparison with the Business-As-Usual (BAU) scenario. Environmental impacts were calculated using global warming potential in terms of greenhouse gas emissions and short-lived climate pollutants. The results revealed that management of MSW within the local authority boundary by integrating recycling, incineration, and sanitary landfill (3:8:1 ratio) offered the highest positive impacts (- 121.84 kg of CO2 eq./ton) while BAU scenario caused the highest negative impacts (250.97 kg of CO2 eq./ton) in comparison with selected scenarios. Moreover, incineration, sanitary landfill, recycling, and anaerobic digestion contributed to emission savings and energy generation. LCA framework was used to identify the composition of MSW for suitable technologies as well as to evaluate the efficiency of existing management mechanisms within a local authority. Evaluation was used to understand the holistic picture of multiple management options to support policymakers in the decision-making process. This framework can be used as a benchmarking tool and bridging concept between the waste management policy and local action plans, which is an important step towards achieving a circular economy for developing countries.Supplementary informationThe online version contains supplementary material available at 10.1007/s43615-022-00200-x.
