Resumo: | Municipal Solid Waste Management (MSWM) with disposal of material in landfills is a practice widely adopted in Brazil. The environmental performance quantification in MSWM supports the proposition of optimized practices. The Life Cycle Assessment (LCA) was applied in this study to evaluate the MSWM, having as functional unit 1 tonne of material managed in Feira de Santana, state of Bahia, Brazil. The system boundary of the MSWM in this study included the material managed in collection, transportation, treatment, disposal and leachate handling stages. The base scenario (C1) considered the disposal of material in a landfill, with flare methane burning. Scenario 2 (C2) adopted an evolution from C1, in which biogas started to be used to generate electricity. Scenario 3 (C3) considered the recovery of resources by recycling the total fraction of dry material such as: Paper, Plastic, Metal and Glass (41 % of the total mass of MSW) and the composting of the wet organic fraction (49 % of the mass total MSW). In Scenario 4 (C4), recycling identical to C3 was adopted and anaerobic digestion of the organic fraction with biogas collection (49 % of the total MSW mass) followed by composting of the digested material. The foreground inventory used representative data for the evaluated scenarios, while the background inventory used the ecoinvent ™ database in the Simapro® software with the Cumulative Energy Demand (CED) and 100 year IPCC-2013 methods. C1 presented the highest values of the evaluated categories, both for CED (215 MJ ∙ t − 1) and for Greenhouse Gas (GHG) emissions (449 kg CO2 eq ∙ t − 1). The C1 presented the greatest contribution of the DEA in the collection and transport, and of GHG at the sanitary landfill. C3 and C4 showed better performances of both CED (–22 550 e – 22 578) MJ ∙ t − 1 and GHG (– 645 e – 622) kg CO2 eq ∙ t − 1 , respectively, due to avoided products mainly from recovered materials . Therefore, the scenarios proposed with the recovery of resources showed potential for reducing the CED and GHG emissions of the MSWM and support the transition to a circular economy. |

A quantificação do desempenho ambiental do GRSU apoia a proposição de práticas otimizadas. A Avaliação do Ciclo de Vida (ACV) foi aplicada nesse estudo para avaliar o GRSU, tendo como unidade funcional 1 tonelada de material gerenciado em Feira de Santana, estado da Bahia, Brasil. A fronteira do sistema do GRSU incluiu o material gerenciado nas etapas de coleta, transporte, tratamento, disposição e manejo do lixiviado. O cenário base (C1) considerou a disposição de material em aterro sanitário, com queima de metano em flare. O Cenário 2 (C2) adotou uma evolução do C1, em que o biogás passou a ser utilizado para gerar eletricidade. O Cenário 3 (C3) considerou a recuperação de recursos com a reciclagem da fração total de material seco como: Papel, Plástico, Metal e Vidro (41 % da massa total de RSU) e a compostagem da fração orgânica úmida (49% da massa total de RSU). No Cenário 4 (C4), foi adotada a reciclagem idêntica ao C3 e a digestão anaeróbia da fração orgânica com aproveitamento do biogás (49% da massa total de RSU) seguida da compostagem do material digerido. O inventário de primeiro plano utilizou dados representativos para os cenários avaliados, enquanto o inventário de segundo plano utilizou a base de dados ecoinvent™ no software Simapro® com os métodos de Demanda de Energia Acumulada (DEA) e IPCC-2013 de 100 anos. O C1 apresentou os maiores valores das categorias avaliadas, tanto de DEA (215 MJ ∙ t−1) quanto das emissões de Gases de Efeito Estufa (GEE) (449 kg CO2 eq ∙ t−1). O C1 apresentou a maior contribuição da DEA na coleta e transporte, e de GEE no aterro sanitário. C3 e C4 apresentaram melhores desempenhos tanto da DEA (–22 550 e – 22 578) MJ ∙ t−1 quanto de GEE (– 645 e – 622) kg CO2 eq ∙ t−1, respectivamente, devido aos produtos evitados principalmente oriundos dos materiais recuperados. Portanto, os cenários propostos com a recuperação dos recursos apresentaram potenciais de redução da DEA e das emissões de GEE do GRSU e apoiam a transição para uma economia circular.Submitted by Renata Aline Souza Silva (rassilva@uefs.br) on 2021-08-27T20:41:25Z No. of bitstreams: 1 Dissertacao_Henrique_2020.pdf: 2946914 bytes, checksum: ab00be853d909f7174d51b996554f016 (MD5)Made available in DSpace on 2021-08-27T20:41:25Z (GMT).

Municipal Solid Waste Management (MSWM) with disposal of material in landfills is a practice widely adopted in Brazil. The environmental performance quantification in MSWM supports the proposition of optimized practices. The Life Cycle Assessment (LCA) was applied in this study to evaluate the MSWM, having as functional unit 1 tonne of material managed in Feira de Santana, state of Bahia, Brazil. The system boundary of the MSWM in this study included the material managed in collection, transportation, treatment, disposal and leachate handling stages. The base scenario (C1) considered the disposal of material in a landfill, with flare methane burning. Scenario 2 (C2) adopted an evolution from C1, in which biogas started to be used to generate electricity. Scenario 3 (C3) considered the recovery of resources by recycling the total fraction of dry material such as: Paper, Plastic, Metal and Glass (41 % of the total mass of MSW) and the composting of the wet organic fraction (49 % of the mass total MSW). In Scenario 4 (C4), recycling identical to C3 was adopted and anaerobic digestion of the organic fraction with biogas collection (49 % of the total MSW mass) followed by composting of the digested material. The foreground inventory used representative data for the evaluated scenarios, while the background inventory used the ecoinvent ™ database in the Simapro® software with the Cumulative Energy Demand (CED) and 100 year IPCC-2013 methods. C1 presented the highest values of the evaluated categories, both for CED (215 MJ ∙ t − 1) and for Greenhouse Gas (GHG) emissions (449 kg CO2 eq ∙ t − 1). The C1 presented the greatest contribution of the DEA in the collection and transport, and of GHG at the sanitary landfill. C3 and C4 showed better performances of both CED (–22 550 e – 22 578) MJ ∙ t − 1 and GHG (– 645 e – 622) kg CO2 eq ∙ t − 1 , respectively, due to avoided products mainly from recovered materials . Therefore, the scenarios proposed with the recovery of resources showed potential for reducing the CED and GHG emissions of the MSWM and support the transition to a circular economy. |
