Based on the promise to revolutionize the entire supply chain, additive manufacturing is seen as an alternative to conventional manufacturing processes, since it simplifies the production of small batches, shortens the distances between production and consumption and generates new distribution models. Due to its huge potential to spread more sustainable environmental practices, investigations on the environmental assumptions, concerning the application of additive manufacturing technologies, are required. Therefore, based on a systematic literature review, this study aimed to analyze the studies that addressed the environmental performance of logistics operations in a comparison among conventional and additive manufacturing, using the Life Cycle Assessment technic (LCA). Although there are few available studies that quantitatively analyze and compare the environmental performance of the additive manufacturing process with traditional process from a transport perspective, it has been concluded that reducing the distances and the quantity of transported products, carbon dioxide emissions and the consumption of energy resources are reduced.
Despite the fact that the construction industry in Brazil is traditionally recognized for the use of craft construction techniques, in the last few years, there has been a growth in the search for new materials, processes, and technologies for this segment. This is mainly due to the great environmental impact that this sector causes. Based on this context, this article aimed to map the constructive processes of existing roofs in the literature, to raise its advantages, disadvantages and previous cases. To achieve this aim, the systematic review method based on three phases – research questions, selection of documents and classification of selected documents, and the 5W2H quality tool were used. Thus, this research could contribute to the literature on this topic, as well as encourage the idealization of new ideas of roof construction processes.
A lo largo de mi desarrollo en el área estudiantil, tanto como ingeniera industrial, como actual magister en project management, he visto la realidad de nuestra sociedad y nuestro entorno, el poder de influencia que poseemos los jóvenes de este siglo y las maneras de generar cambio en las áreas en las que nos desempeñamos.
Faz alguns anos que as questões ambientais vêm ocupando espaço de destaque em conferências sobre o desenvolvimento sustentável. Identificar os possíveis impactos ambientais e atuar de modo a minimizá-los, tornou-se uma das prioridades em organizações de diversos segmentos. O mesmo ocorre para a indústria da construção civil que, devido ao consumo de recursos e energia, torna-se responsável por impactos ambientais ao longo do ciclo de vida dos seus produtos. À vista disso, esse trabalho teve o objetivo de destacar os principais itens das fases da Avaliação do Ciclo de Vida (ACV) (definição do objetivo e escopo, inventário e avaliação do impacto) e identificar os métodos de AICV (Avaliação do Impacto do Ciclo de Vida) aplicados à avaliação de residências unifamiliares. Por meio de uma revisão sistemática da literatura, verificou-se que as categorias de impacto que mais se destacaram foram a depleção da camada de ozônio, eutrofização, acidificação, mudanças climáticas, esgotamento de recursos e toxicidade humana. Além disso, métodos como ReCiPe, Eco-indicator 99, IMPACT 2002+ e o CML foram identificados como os mais adequados para a avaliação de edificações.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
