Article Synopsis
  • The study used simulations and genetic algorithms to optimize the reverse logistics network for waste from electrical and electronic equipment (WEEE) in Sao Paulo, Brazil, aiming to enhance the circular economy.
  • The economic evaluation focused on cost reductions in aspects like fuel, maintenance, and insurance, while the environmental analysis measured impacts like greenhouse gases and land usage.
  • Overall, the optimized WEEE reverse chain was found to reduce collection frequency and improve both economic and environmental outcomes, making it a practical model for other regions aiming to minimize their carbon footprint by 2030.

Using emergetic indicators to evaluate complex processes such as the de-pollution of urban rivers aims to contribute to better use and preservation of the resources, besides the valuation of ecosystem services provided by the water body. Within this context, we conducted a bibliometric and systematic review that shows the lack of emergetic indicators in urban river de-pollution. Thus, this work aims to propose an emergetic assessment procedure to evaluate the de-pollution process of urban rivers that allows technicians, academics, and revitalization process managers of urban rivers to improve the monitoring and decision-making directly related to the process, concluding that an emergetic assessment procedure contributes to theory to create new scientific analyses applied to urban revitalization and nature preservation processes.

Industrial and economic growth activities induce an increase in the generation and emission of large amounts of polluting waste to the environment. However, the scarcity of natural resources in ecosystems denotes the importance of the practical application of Circular Economy (CE) at the micro level. This research aims to evaluate the environmental and economic advantages of adopting waste recycling and reuse processes based on the CE in four industrial companies in the metal-mechanical sector.

There is a growing demand for the adoption of cyclical processes in the fashion industry. The trends point to the reuse of cellulose from cotton fibres, obtained from industrial waste, as a substitute to the former linear processes of manufacturing, sale, use, and discarding. This study sets up to explore and assess the economic and environmental gains from the mechanical shredding of cellulose in cotton fabrics in a textile company, identifying the circularity associated with the adoption of such methods.

The objective of this study was to evaluate the moderating effect of Occupational Health and Safety actions based on the World Health Organization (WHO) recommendations to mitigate the negative effect of COVID-19 on the operational, logistical, marketing (OLMP), and health and safety performance (OHSP) of workers in multinational industries. The development of surveys in companies was the method adopted, which had confirmatory evaluations through Structural Equations Modelling (SEM). As a result, it was confirmed that this is one of the few scientific studies that expectedly validates that the COVID-19 pandemic has severely impacted operational, logistical, market, and Occupational Health and Safety (OHS) performance.

The coronavirus pandemic meant that companies had to adapt quickly to survive the challenging scenario and avoid losing market share or even going bankrupt. In this sense, employees dedicated to Occupational Health and Safety (OH&S) activities within organizations played a key role in ensuring that the recommendations of the World Health Organization (WHO) were properly implemented. Even so, no studies were identified in the literature that investigated how the practices to combat COVID-19 improved the performance related to employee safety and occupational health.

The Metal Finishing Industry (MFI) use water and several chemicals in its production chain, which generatesboth liquid and solid hazardous waste. The present study evaluatesthe economic and environmental advantages of implementing cleaner production (CP) in a Brazilian MFI specialized in chrome and zinc. For the economic assessment, we adopted the measures of return on investment and internal rate of return.

Currently, the concern with the environment is increasing and organizations seek solutions to preserve nature and at the same time earn higher profits or competitiveness. For this, they make frequent use of structured procedures in order to reduce their costs and expenses. However, it has not been always considered the environmental performance related to the financial performance of these processes.
