“…LCA studies related to solid waste management have been disseminated in different regions of Brazil, predominantly in the Southeast (PAES et al, 2020a;PAES et al, 2020b) and South (MERSONI & REICHERT, 2017). However, studies related to the Amazon are rare, with emphasis on Oliveira et al (2022).…”

In the Amazon, around 80% of the municipalities dispose of their waste in open-air dumps, challenging government agencies to find alternatives for its management. In this context, the Life Cycle Assessment (LCA) methodology has been used to analyze the environmental impact of municipal solid waste (MSW) management system scenarios. The objective of this chapter was to analyze municipal solid waste management scenarios, based on the LCA methodology, in the municipality of Humaitá, state of Amazonas, including the collection of waste from indigenous communities. This study included secondary data from articles published by a research partnership between the São Paulo State University (Unesp) and the Federal University of Amazonas (UFAM). The LCA followed the model proposed by ISO 14040 and 14044 and was performed using the Simapro software. The environmental impact category assessed corresponded to greenhouse gas (GHG) emissions, expressed in kgCO2eq. Three scenarios were evaluated: a) Base scenario (CB): which corresponded to the collection of waste from the urban area of Humaitá, transport, and disposal in a sanitary landfill; b) Scenario 1 (C1): which corresponded to CB with the inclusion of the collection of waste generated in indigenous areas; c) Scenario 2 (C2): corresponded to C1, excluding organic waste, which would be destined for composting. The analysis of the inventories of each scenario led to the conclusion that including the collection of solid waste from indigenous reserves would increase GHG emissions by 4%.

Nanoparticle synthesis methodologies have been developed over the last decades for reducing the concentrations of pesticides such as atrazine in the environment. In this work, life cycle assessment (LCA) and economic performance analysis tools were used to evaluate the eco-efficiency transition of two laboratory-scale synthesis processes for polymeric nanoparticles (NPo) containing atrazine (ATZ), namely, a double emulsion process (DEm) and a nanoprecipitation process (NPr). Life cycle inventories for both synthesis processes included the flows of matter and energy at a laboratory scale, complementing information from the Ecoinvent database. LCA used the ReCiPe 2016 methodology with a midpoint (H) to produce NPo + ATZ at a concentration of 1 mg ATZ mL–1 of final solution (functional unit). For both processes, freshwater ecotoxicity stood out among the impact categories evaluated, due to significant electricity consumption. The DEm process had a 61% higher total environmental impact, compared to the NPr process. The total cost of the DEm process per functional unit was 5% higher than that of the NPr process. Therefore, NPr achieved a gain of 54% for the eco-efficiency transition, in relation to DEm, for the production of NPo + ATZ. Two steps influenced this result that only occurred in the DEm process: sonication and the use of dichloromethane. Therefore, eco-efficiency enabled identification of the greener production process and the steps that had greater environmental and economic impacts in two NPo synthesis processes.
