Background: The wide variety of terms that converge in reverse logistics have been more evident and discussed in the current context of the literature, such as reverse channels, reverse supply chain, closed-loop supply chain, and circular supply chain. Regarding this, this paper aimed to investigate the level of uncertainty about the activities that make up the Reverse Logistics process in the opinion of professionals working in this area in Brazil, to develop a discussion relating to the sustainable development goals proposed by the UN and their importance for the future of logistics networks. Methods: Initially, through a detailed systematic review of the literature, the activities that make up the RL processes were identified. Then, a questionnaire was elaborated on regarding such activities, and a survey was developed with professionals in the area. The data obtained were analyzed through a descriptive analysis of means, calculation of Cronbach’s Alpha, and using the multicriteria decision technique TOPSIS. Results: It is possible to see that professionals involved with RL processes in Brazil still have many doubts regarding which activities belong to the RL process. In the opinion of Brazilian professionals, 10 of these activities have generated high levels of uncertainties about their belonging or not to the RL process. On the other hand, with a low level of uncertainty, 3 activities were not considered and 3 were considered to make up the RL process. Conclusions: It is believed that this study can contribute to the generation of knowledge by comparing basic information in the scientific literature with the practical knowledge of professionals belonging to the reverse logistics sector working in the Brazilian context.

Background: This study aimed to identify the most widespread performance objectives for the vehicle routing problem, the degree of comparative importance attributed to each of these performance objectives in the opinion of professionals in the logistics area working in Brazil and also relate them to aspects of sustainability considering environmental, economic and social issues. Methods: To this end, a literature review was carried out in the area and a survey was developed with professionals through a structured questionnaire. The collected data were treated using the TOPSIS multi-criteria technique. Results: The results indicate that the performance objectives in route plans “level of service”, “total number of vehicles” and “total distance travelled” are the ones that, in the opinion of the professionals participating in the research, have greater importance in the planning and elaboration of plan routes and that such objectives directly impact the sustainable results of a given organization. Conclusions: The results can serve as a basis for researchers in the area who aim to broaden the debates on this topic and for logistics operations managers who work directly with planning and elaboration of route plans and who aim to make their operations more sustainable. Therefore, this research addresses the literature gap by identifying which performance objectives should be considered in the elaboration of route plans and how they relate to sustainability guidelines. It is noteworthy that no other study with a similar objective was identified in the literature.

Background: The interest in the topic of performance assessment in reverse supply chains (RSC) is increasing, although the body of research is still in its early stages. As this is a developing field, it is crucial to expand discussions on topics that have not yet been thoroughly examined, such as the intrinsic bias of indicators and metrics that may be associated with specific operational, economic, environmental perspectives, etc. Such perspectives should be considered in the decision-making process within the context of reverse logistics (RL) and waste management (WM). The aim of this research was to identify different perspectives employed in the development of proposed models in the literature. Methods: A systematic literature review was conducted to analyze thirty papers from Scopus, Web of Science, and Science Direct databases without time restrictions. Results: The review identified various ways in which authors grouped perspectives, including qualitative and quantitative, sustainability, and operational perspectives, among others. Conclusions: This study revealed several gaps in the field, including limited studies on RSC performance assessment and a lack of studies linking performance assessment to decision-making components.

The study has as purpose to identify, analyze, and validate challenge constructs of Industry 4.0, which can affect the promotion of sustainability within the industry. A systematic literature review was conducted to identify challenges to the promotion of Industry 4.0 sustainability. A set of seventy challenges were grouped into the following eight constructs: finances, technology, organizational, human resources, legislation, geopolitical and economic factors, and both internal and external factors. Subsequently, the same constructs were validated using a survey involving industry professionals. The data were analyzed using the Lawshe method. Five constructs within the eight constructs were considered relevant to industry sustainability according to the experts’ opinion. The validated set of constructs included: finance, technology, organizational, human resources, and internal factors. This study contributes to the literature in the field by addressing a research gap of constructs identification based on expert’s opinions that impact Industry 4.0 in promotion of sustainable development. This study delivers theoretical and practical implications. From a theoretical standpoint, it contributes to expanding knowledge by providing valuable insights into the adoption of Industry 4.0 and its specific challenges concerning the pursuit of more sustainable practices. These implications extend to diverse research areas given the multidisciplinary nature of Industry 4.0.

The Civil Construction industry is one of the largest generators of waste, which when improperly disposed of, lead to irreversible environmental implications. Effective management of these materials can recycle about 90% of the waste, minimizing environmental impacts. In this sense, the research aimed to provide an overview of the implementation of reverse logistics in Construction and Demolition Waste, highlighting the main gaps in the research scenario. For the selection of the analyzed articles, a string was defined and searched in the Web of Science journal database. The search resulted in 45 articles from 20 journals, which were analyzed using the VOSviewer software. The results revealed a significant concentration of studies in journals such as "Journal of Cleaner Production", "Waste Management & Research" and "Sustainability", and highlighted the most relevant keywords, such as "reverse logistics", "construction and demolition waste" and "waste management". However, emerging research trends were evidenced, such as the challenges of implementing reverse logistics in C&D waste and the importance of recycling for circular economy and environmental sustainability. The conclusions emphasize the importance of a multidisciplinary approach in C&D waste management, highlighting challenges from the construction process to waste recycling and recovery. Additionally, the need for models and systems to improve performance in reverse logistics implementation is emphasized. Finally, the importance of exploring advanced technologies and public-private partnerships to promote the effectiveness of reverse logistics in C&D waste is emphasized.

O processo de reciclagem envolve etapas relacionadas à sua cadeia de produção, como: coleta, triagem, enfardamento, comercialização, transporte, enfardamento pela indústria e desenvolvimento de novo produto. Em algumas dessas etapas há dificuldades para a eficiente realização das atividades. Portanto, essa pesquisa objetivou propor melhorias ao processo de Logística Reversa (LR) em uma cooperativa de catadores, atuante no município de Ananindeua-PA, tendo como referência as diretrizes da Política Nacional de Resíduos Sólidos (PNRS). Assim, para cada etapa da cadeia produtiva foram mapeadas as atividades envolvidas no processo de Coleta Seletiva (CS), analisando-se os aspectos operacionais relativos a cada atividade, identificando as etapas-gargalos inerentes à produção, com o objetivo de propor melhorias ao processo de LR de uma cooperativa de catadores localizada em Ananindeua-PA. Para tal, esta pesquisa baseou-se em um levantamento bibliográfico considerando os temas associados, a saber LR, Gestão Integrada de Resíduos Sólidos, Mapeamento de Processos, PNRS e CS. Envolveu ainda a coleta de dados com o auxílio de levantamento documental, entrevistas não-estruturadas, observações in loco e pesquisas de campo. Como resultados, a identificação de não-conformidades do processo adotado pela cooperativa, uma proposta de processo aderente à PNRS e melhorias sugeridas relacionadas à saúde e segurança, layout e equipamentos.
