“…Among the most common LCA issues in practice are, first, the high demands on time and input data; second, the uncertainty regarding the content of some particles of the analysed LCA chain; and third, that in practice, it is not necessary to analyse the complete LCA chain, which may be debatable with respect to the abovementioned point. That last statement is supported by several works [48][49][50][51]. That logic brings us, for practical purposes, unambiguously to a deeper analysis of the selected part of the LCA chain.…”

This paper aims to deal with CO2 emissions in energy production process in an original way, based on calculations of total specific CO2 emissions, depending on the type of fuel and the transport distance. This paper has ambition to set a break point from where it is not worthwhile to use wood as an energy carrier as the alternative to coal. The reason for our study is the social urgency of selected problem. For example, in the area of public sector decision-making, wood heating is promoted regardless of the availability within the reasonable distance. From the current state of the research, it is also clear that none of the studies compare coal and biomass fuel transportation from the point of view of CO2 production. For this purpose, an original methodology has been proposed. It is based on a modified life cycle assessment (LCA), supplemented with a system of equations. The proposed methodology has a generalizable nature, and therefore, it can be applied to different regions. However, calculation inputs and modelling are based on specific site data. Based on the presented numerical analysis, the key finding is the break point for associated processes at a distance of 1779.64 km, since when that it is better to burn brown coal than wood in terms of total CO2 emissions. We can conclude that, in some cases, it is more efficient to use coal instead of wood as fuel in terms of CO2 emissions, particularly in regard to transport distance and type of transport.

“…The release of heavy metals in industrial soil is magnified in the case of EAL (1.13 kgDCB-eq./fu) due to the landfill process. Other authors confirm the release of heavy metals from the landfill [43] (which are reduced when electricity production is considered) or from the incineration process [22] as the major impact for this category. When compared to published works [34], Sc0 assured a good result for this category of impact (literature values ranging from −7.64 × 10 −3 kgDCB-eq./fu to 5.77 × 10 −2 kgDCB-eq./fu).…”

“…Weight % A life cycle assessment (LCA) approach is a very useful tool in the evaluation of the contribution of each of the processes to the overall efficiency picture of the disposal options. Arena et al [21] and Tarantini et al [22] compared the performance of alternative solid waste management in Italy quantifying the relative advantages and disadvantages for several options, while Liu et al [23] evaluated the urban solid waste handling options in China and Menikpura et al [24] assessed the sustainability of an integrated waste management system in Thailand, all of them using LCA as a decision-support tool. Although this is a very powerful mean, aspects such as the lack of transparency or wrong methodology assumptions may lead to difficult comparisons or even deficient interpretation of the results as reviewed for municipal solid waste by Cleary [25].…”

Environmental Analysis of Waste-to-Energy—A Portuguese Case Study

2018

Environmental evaluation of the waste treatment processes for the area of Greater Porto (Portugal) is presented for the year 2015. The raw data for the energy recovery plant (ERP) provided by the waste management entity were modelled into nine environmental impact categories, resorting to a life cycle assessment dedicated software (GaBi) for the treatment of 1 tonne of residues. Also, a sensitivity analysis was conducted for five scenarios in order to verify the assessment quality. Results were compared to two European average situations (typical incineration plant and sanitary landfill with no waste pre-treatment), which showed that these facilities perform better or at the same level as the average European situation, mostly due to the high efficiency observed at the ERP and to the electricity production in the incineration process. A detailed analysis concluded that these helped to mitigate the environmental impacts caused by some of the processes involved in the waste-to-energy technology (landfill showing the harder impacts), by saving material resources as well as avoiding emissions to fresh water and air. The overall performance of the energy recovery plant was relevant, 1 tonne of waste saving up to 1.3 million kg of resources and materials. Regarding the environmental indicators, enhanced results were achieved especially for the global warming potential (−171 kg CO 2-eq.), eutrophication potential (−39 × 10 −3 kg PO 4-eq.) and terrestrial ecotoxicity potential (−59 × 10 −3 kg DCB-eq.) categories. This work was the first to characterize this Portuguese incineration plant according to the used methodology, supporting the necessary follow-up required by legal frameworks proposed by European Union (EU), once this facility serves a wide populational zone and therefore is representative of the current waste management tendency in the country. LCA (life cycle assessment) was confirmed as a suitable and reliable approach to evaluate the environmental impacts of the waste management scenarios, acting as a functional tool that helps decision-makers to proceed accordingly.

“…O potencial de impacto por eutrofização acontece, sobretudo, pela elevada concentração de nitratos e amônia no lixiviado de aterro, mesmo que este seja devidamente tratado em estação de tratamento [18]. Reichert [6] afirma que a eutrofização diz respeito aos impactos potenciais relacionados à concentração excessiva de macronutrientes, principalmente de nitrogênio e fósforo.…”

A tomada de decisões na área de gerenciamento de resíduos sólidos tem se mostrado como um dos principais desafios aos gestores públicos. A utilização de ferramentas que auxiliem na obtenção das melhores decisões, permitindo economia de recursos financeiros, juntamente com a minimização dos impactos ao meio ambiente, assume grande importância. O presente trabalho apresenta um estudo diagnóstico do gerenciamento integrado de resíduos sólidos urbanos no município de Três Cachoeiras (RS) por meio da técnica de Avaliação do Ciclo de Vida (ACV). Para a realização da Avaliação do Ciclo de Vida, utilizou-se o programa computacional Integrated Waste Management (IWM) -2, Versão 2.5. Para converter os valores obtidos na ACV em impactos ambientais, foram realizadas simulações com base nos fatores de caracterização utilizados pelo programa computacional SimaPro® da Pré Consultants e publicados no relatório ReCiPe 2008, versão 1.08. Foram realizadas as Avaliações do Ciclo Vida do cenário atual de gerenciamento dos resíduos e de mais três cenários de gerenciamento. Os resultados revelam que a disposição final dos resíduos em aterro controlado é a etapa com maiores contribuições para impactos ambientais. O cenário 4, composto pelas etapas de coleta, transporte, triagem dos resíduos sólidos urbanos passíveis de reciclagem, triagem da matéria orgânica e aterro sanitário, apresenta os menores índices de contribuição para impactos ambientais, revelando uma redução de 89% no potencial de aquecimento global, 20,1% no potencial de acidificação, 39,4% no potencial de eutrofização, 82,3% no potencial de depleção da camada de ozônio, 42,7% no potencial de toxicidade humana referente às emissões atmosféricas e 48,5% na redução do volume dos resíduos no aterro sanitário.Palavras-chave: Avaliação do Ciclo de Vida. Impactos Ambientais. Resíduos Sólidos Urbanos. ____________________________________________________________________________________________________________ IntroduçãoA geração de resíduos sólidos urbanos têm aumentado de forma significativa, em especial nas últimas duas décadas. Frente a isso, fica evidente a necessidade do correto gerenciamento desses resíduos, a fim de evitar problemas à saúde pública e impactos ao meio ambiente.O gerenciamento de resíduos sólidos urbanos deve ser integrado, ou seja, deve englobar etapas articuladas entre si, desde a não geração até a disposição final, com atividades compatíveis com as dos demais sistemas de saneamento ambiental. Para isso, torna-se essencial a participação ativa e cooperativa do primeiro, segundo e terceiro setor, respectivamente, isto é, do governo, da iniciativa privada e da sociedade civil organizada [1].McDougall e colaboradores [2] afirmam que um sistema de gestão de resíduos sólidos deve ser: ambientalmente eficiente, isto é, reduzir ao máximo os resíduos gerados, bem como as emissões gasosas e líquidas; economicamente suportável, ou seja, operar a custos que possam ser suportados por toda a sociedade; e, socialmente aceito, Istoé, operar de modo a ser aceito pela maior p...
