Production systems are being restructured to close production cycles via implementing circular economy (CE) practices. The planted tree industry in Brazil has shown potential for applying CE practices due to its efficient use of resources and inclination towards environmental innovation. However, some gaps and difficulties have been observed in several industrial segments so that the logic of the circular production system is put into practice more effectively and intensely. In this context, the aim was to investigate the use and impacts of CE practices in the Brazilian planted tree industry by sector of operation and scale of enterprises based on the ReSOLVE framework. Data were collected from 34 companies that answered a questionnaire, corresponding to 47.2% of Brazilian planted tree industry companies. Data analysis involved univariate and multivariate statistical techniques, considering the grouping of companies by sector of activity (forest producer, pulp and paper, and timber processing) and scale (small, medium, and large). The results revealed that "pulp and paper" and medium- and large-scale companies had the most significant application of CE practices and reported more significant impacts. [Display omitted] • Explores a segmented analysis of the circular economy by scale and sub-sector groups. • Scores of circular practices and their impacts are presented according to the groups. • The association between circular practices and impacts by group are analyzed. • Propositions to enable the adoption of circular practices are presented.

This paper aims to introduce a new sustainable business excellence model, called Knowledge Management Excellence Model 21 (KMEM21), a theoretical framework that combines Knowledge Management and Business Excellence Models (BEMs), proposing an approach applicable to organizations to directly contribute towards achieving the United Nations Sustainable Development Goals (SDGs). The paper through a qualitative-exploratory methodology makes an analysis and benchmarking, emphasizes the integration of Knowledge Management and three specific Business Excellence Models (Management Excellence Model (MEG) from Brazil, Baldrige Excellence Framework, and EFQM). This integration uncovers relationships between organizational concepts associated with Knowledge Management and BEMs, which contributes to new insights in the literature regarding these concepts' interplay. BEMs are presented as tools that can catalyze the power of Knowledge Management towards achieving SDGs. However, it's noted that the existing BEMs might not be adequate, as the goal extends beyond organizational improvement and excellence to encompass sustainable development aligned with SDGs. The article suggests that specific organizational concepts, identified through a literature review and aligned with Knowledge Management and BEMs, can be selected as indicators associated with the constructed KMEM21 and the SDGs. These indicators are intended to form a bridge between the new model and the SDGs. However, given the comprehensive nature of the theory, model development, application, result acquisition, and analysis, the article's primary contribution will be in its focus on elaborating the instrument and technique, demonstrating the creation of a theoretical framework for the SDGs. Future works will showcase the application of the proposed KMEM21 method in five Brazilian organizations, members of Global Compact, to compare the achieved objectives and the results obtained with the organizations' performance and their sustainability reports. [Display omitted] • There is a visible relationship between knowledge management and business excellence models, aided by shared organizational concepts. • Achieving the SDGs in organizations can be done by using the traits incorporated into knowledge management and business excellence models. • The Knowledge Management Excellence Model 21 represents an original approach, acting as a new sustainable business excellence model. • A comprehensive model can be constructed using a methodology that incorporates an instrument, a technique, and a method. • KMEM21 presents a strategic path that aligns with business excellence principles and the sustainable development objectives, offering a framework for organizational success.

The positive results of manufacturing companies adopting lean production practices certainly impacted the adaptation of Lean Manufacturing principles to the service sector, culminating in what we know today as Lean Office. Based on this approach, many Universities have adopted lean principles and practices to improve their administrative processes and thus add value to their students, faculty and staff. From this perspective, but going further, the present research has the general objective of raising the main sustainable impacts generated by a University through the application of Lean Office in its administrative processes. Methodologically, the research is supported by a case study at a Federal Public University in Brazil, where two service processes will be analyzed, one aimed at students and the other at employees (teachers and technicians). The work is conducted according to the phases and steps recommended by the LEFI Method (Lean Evaluation and Future Improvement), with a significant part of the results obtained by the steps related to Value Stream Mapping. As the main results, it is observed that the elimination of waste in administrative processes at the University target of the present study culminated, only in the year 2021, in the saving of 444,754 sheets of printed paper that, due to all its consequences, indirectly impacted the economy of 1,380,000 L of water, in the non-emission of 43.82 kg of CO2 and the preservation of 67 trees. • The Lean philosophy has been gaining relevance in service processes • There is a synergy between Lean principles and Business Sustainability • The Lean office contributes to the users' satisfaction with university services • Value Stream Mapping is an excellent starting point for eliminating waste • The application of Lean Office in Universities contributes to Sustainable results [ABSTRACT FROM AUTHOR]

The global economy is advancing towards a low-carbon future. Alongside this energy transition, the sustainability concept has become a fundamental value of our society, encouraging a worldwide discussion on the consideration of socio-environmental issues by the energy sector. In Brazil, the electricity generation expansion planning has not been doing enough to incorporate these issues into its decision-making process, especially in regards to alternative and renewable energy sources. Considering that Life Cycle Sustainability Assessment (LCSA) is suitable for addressing this situation, we focus on one of its first steps, which consists of defining a set of indicators able to communicate sustainability issues. With this in mind, this paper aims at incorporating sustainability into the decision-making process concerning electricity generation in Brazil by formulating a set of indicators. We carry out a systematic review for collecting the leading environmental, social, and economic indicators used by scientific papers focused on recent and practical LCSA studies concerning electricity generation and that contemplate alternative and renewable energy sources. Thus, we analyze the frequency of indicators in a sample of 41 papers and screen them against selection criteria and their relevance for the Brazilian context. As a result, we establish a set of 28 indicators (18 environmental, four social, and six economic). It is clear from our findings that LCSA practitioners have been facing different levels of methodological and practical challenges depending on the dimension of sustainability, which reflects on the number of environmental, social, and economic indicators collected from the overall sample. • 28 indicators have been selected from a systematic review of practical LCSA studies. • Traditional communities and protected areas were included in this set of indicators. • The final set of indicators covers environmental, social, economic dimensions. • They can be used to incorporate sustainability into the Brazilian electricity sector. • Practical LCSA studies in the electricity sector mainly address environmental issues.

Lamb production in Brazil has the state of São Paulo as its largest consumer market, but due to competition for area with other agricultural activities, sheep farming in São Paulo underwent an intensification of the production system to achieve better economic profitability. This intensification can compromise the sustainability of the system. There is no research concerning about emergy evaluation on lamb production systems applied in Brazil, so this is the first paper to discuss the sustainability of lamb production systems using this method. Therefore, this article proposes to discuss the importance of considering environmental aspects in the economic analysis of production systems, aiming at the sustainable development of the sector. This study assessed the economic and emergy performance of three different sheep farms in Brazil managed under different levels of technology: Intensive, Semi-intensive, and Feedlot. Results show that from an economic perspective, the Feedlot system is more attractive (9,800 US$/yr for net profit) than Intensive and Semi-intensive ones, while emergy synthesis show that Semi-intensive system (30% for renewability) should be prioritized. On the other hand, when emergy is analyzed from an economic perspective based on Emdollars (Em$, with an 'm'), the economic advantage regarding the production cost of Feedlot on the Semi-intensive system becomes less evident. The Intensive system obtained the worst performance for economic, and emergy indicators. More than contributing to the discussions about the importance in considering a systemic perspective when quantifying the economic performance of production systems, this study also (i) establishes the most sustainable sheep farm system that could be supported in Brazil, and (ii) make available new unit emergy values that would enrich the existing emergy databases. • The synthesis emergy together with the economic assessment are performed for three sheep production systems with different levels of technology. • Intensive systems (Intensive and Feedlot) are economically profitable, but generate greater pressure on the environment. • Semi-intensive systems present less pressure on the environment, but are not economically viable.
