This article aims to list the main sustainable practices developed in the processes of metal forming, casting, heat treatment, welding and electrostatic painting. When analysed the literature about sustainable manufacturing, a predominance of studies about machining is observed and the processes mentioned are few explored in academic studies. The research strategy used to reach the objective was systematic literature review, conducted for each process cited. Many sustainable practices were identified with prominence of better materials use and energy efficiency. The authors of this article believe that the information presented here can be useful for researches in their future studies and for industry professionals interested in improving manufacturing processes.
The logistics sector is characterised as an important pillar of the Brazilian economy, significant regarding revenue and job creation. This study aims to critically analyse the logistical operations developed by Brazilian companies in the context of Logistics 4.0 and to structure a SWOT (strengths, weaknesses, opportunities and threats) matrix from the information gathered. In addition, relationships were established between the structured SWOT matrix and the targets of Sustainable Development Goal 9 (SDG 9). The methodological approach taken by the study consisted of semi-structured interviews with ten experts and data were analysed through content analysis. Once structured the SWOT matrix, the results were related with the targets of the SDG 9. The study presented the weaknesses and threats stand out in relation to the strengths and opportunities. When compared with the targets of SDG 9, it is possible to observe that many weaknesses are related to infrastructure and innovation. The main contributions of the study are the following: it is one of the few studies which holistically examined the sector in Brazil from a Logistics 4.0 perspective and the study points out some essential needs which should be addressed. The information presented here can broaden the debates on this topic and assist companies and government in the transition to digital transformation.
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.
