The purpose of this paper is to introduce a new methodology called overall greenness performance for value stream mapping (OGP-VSM). Using value-added concepts, this approach has the potential to integrate, measure, control and improve productive and environmental performance in accordance with a company’s context.

The OGP-VSM approach was developed by reviewing and integrating the environmental aspects of existing lean thinking tools and approaches.

This research revealed the lack of practical integration between productive and environmental performance. Using OGP-VSM, managers can see that environmental practices have a direct impact on productivity. OGP-VSM allows a balance to be found between lean and green practices in order to achieve the simultaneous improvement of productivity and environmental performance.

The proposed approach is applied to a case study in an automotive company in Spain and lays the groundwork for moving toward functional environmental sustainability in manufacturers.

Companies are increasingly implementing environmentally focused practices. Pursuing environmentally friendly (green) performance poses several challenges, but it also affords opportunities to create new methodologies for generating a competitive advantage for manufacturing companies. There are a limited number of approaches to drawing together the elements and attributes that are essential for a holistic, practical and long-lasting improvement of environmental performance in the manufacturing sector.

Urban logistics presents a series of challenges, as the interests of the different stakeholders are not always aligned. The aim of this research is to explore the potential of applying Lean principles to reduce waste in urban logistics.

As a structure for “going to gemba,” the authors implemented the shadowing technique to better understand the perspective of companies distributing products in the city of Montevideo, Uruguay. Then, meetings were conducted to validate the observations by the people shadowed.

The results show that most of shipper's time is dedicated to waiting (59%), which is followed by driving (22%), and only a small section of time was dedicated to unloading and verification activities (19%). Although collaborative solutions are needed along with the different stakeholders, this research highlights how deploying Lean thinking can improve significantly urban logistics achieving up to 25% improvement in the number of stores served per shift.

From an academic point of view, this study emphasizes the importance of continue applying and evaluating the Lean practices into transportation contexts. From a company's perspective, the authors have presented a list of propositions that can be implemented for carriers in order to reduce waste and/or improve the efficiency of the urban transportation process.

Based on the literature review carried out, the subject study of Lean and its application to urban logistics remains mostly unexplored in the scientific literature.

This paper proposes a maturity model to indicate the operational excellence (OE) implementation status of businesses in emerging countries, considering its importance in Industry 4.0.

The study involves four steps. First, undertake a study of the literature to identify the variables to consider in the maturity model; second, identify how to organize the variables found in the first step; third, structure a questionnaire to define the maturity model; and lastly, validate the variables found in the literature and the maturity levels.

A total of 23 variables were validated through interviews with general managers, operation managers and experts within organizations. Interviews were carried out in 49 companies from different sectors. Five maturity levels were defined in this study: basic level, beginner level, training level, innovative level and champion level.

Many businesses are implementing OE as a practice to remain competitive in their industries, targeting economic, environmental and social sustainability. However, OE implementation in companies from developing or emerging countries is far below the average level of that in developed companies due to cultural, political or economic constraints. To the best of the authors’ knowledge, there is no model that indicates the status of OE implementation in companies from emerging countries or the different levels to implement OE. This study fills the mentioned gap.

The purpose of this study is to propose a new mapping tool called Circular Value Stream Mapping (C-VSM) that combines Circular Economy principles with Lean tools to enhance sustainability performance in operations.

To develop the C-VSM tool, the researchers conducted a literature review and a focus group. The tool was then applied to two real case studies in the agri-food sector, specifically analyzing an artichoke and olive oil producer, to assess its validity and effectiveness.

The study introduces the Circular Resource Box (CRB) as a key innovation in the C-VSM tool. This visual representation effectively captures resource circularity and how resources and wastes are managed, making it easy to identify circularity in the production process. By combining qualitative and quantitative information with this visual representation, companies can identify improvement opportunities aligned with the CE.

The research is limited in scope as it focuses on the application of the C-VSM tool in the agri-food sector. Further research could explore its applicability in other industries and settings to understand its broader impact.

The C-VSM tool provides practical benefits to companies seeking to transition from linear to circular production processes. It enables practitioners to identify opportunities to reduce environmental impacts and optimize production operations in line with CE.

The introduction of the C-VSM tool is a novel approach that bridges the gap between Lean Manufacturing and CE concepts, advancing the understanding of how CE thinking can be effectively implemented in operations.

The purpose of this paper is to analyze gaps and trends, as well suggest approaches and methodologies that should be addressed by future studies for implementing the lean and green management in the agri-food sector.

Based on a sample with 117 papers, this paper presents a systematic review on the integration of lean and green in the agri-food sector.

Key findings indicate that research on lean and green topics has increased in recent years, an important gap in the integration of lean and green in the agri-food sector has been identified. Two paths that remain open for further research are detected: the lack of theoretical, prescriptive and quantitative research and the possibility of integrating the two most used tools of lean (i.e. value stream mapping) and green (i.e. life-cycle assessment).

This study does not only advance the theoretical knowledge of the lean and green field, but it is also beneficial for agri-food companies who aim to effectively deploy lean and green in their processes in order to improve both operational and environmental performances.

No other industry matches in such a complete way the agri-food industry’s challenge of sustainability that is due to the amount of resources it consumes and its interrelatedness with the well-being of humanity.

There are separate streams of established research on lean and green management in the agri-food sector, yet very few authors have addressed the intersection of these strategic initiatives.

The purpose of this paper is to develop a methodology that is based on the concept of environmental comfort and can serve as a tool that can help companies and employees to implement Kaizen projects. This methodology focuses on the worker’s participation in analyzing and developing improvements related to their workplace.

This research is focused on the development of a methodology that encourages worker participation in improvement activities, through the analysis of their working conditions. For this purpose, the proposed methodology was developed in accordance with the dimensions of workplace comfort proposed by Vischer. The employees start working on the analysis of problems and their solutions through the logical framework approach, as it is a tool that encourages worker participation and consensus. The developed methodology was applied in a company, with three different groups of people, which enabled the authors to test its utility.

The findings reveal that the proposed methodology is effective in initiating workers in the path of Kaizen. The employees who applied this methodology were able to propose improvement actions that addressed the problems and opportunities that they had previously detected. Moreover, the questionnaire that was used to validate the methodology and was administered to employees shows that the methodology is useful in preparing them for adopting continuous improvement (CI) programs.

The methodology presented in this paper has been applied and evaluated by a small number of employees. These limitations suggest future research recommendations.

This participatory methodology could be used by different types of companies to initiate employees on the path of CI, even if they are not familiar with improvement programs or methodologies. In addition, its use could improve the capabilities of employees in areas such as participatory analysis, problem identification and proposal of objectives. These capabilities are necessary in any Kaizen project. As a result of the application of this methodology, the companies could obtain a list of areas of improvement related to their work and propose actions to work on.

The paper presents the use of environmental comfort in the workplace as the first step in accomplishing a Kaizen project, with a focus on the employee involvement and consensus.

Environmental management (EM) is becoming increasingly important in all types of organizations. The food industry represents the top industrial sector of the Spanish economy; however, there is still little knowledge about how it is managed environmentally. The purpose of this paper is to present a descriptive analysis of the Spanish food sector.

This study undertook a descriptive analysis based on probabilistic sampling surveys from food companies in Spain. The survey was sent out to 900 companies obtaining 128 answers.

The results of this study show that companies with an EM standard tend to have a more developed system and a greater presence of EM tools and actions. Moreover, statistical differences were identified among the characteristics of companies and various factors that affect the evolution of their EM.

There are no studies that reveal a clear picture of the status of EM in the Spanish food industry. This study presents a clear starting point that might help policy makers, consultants, researchers and other parties to set new improvement routes so companies do not get stuck in their progress toward environmental excellence.

This research has the following specific objectives: provide an overview of the literature addressing operational excellence (OE) and OE in emerging countries; propose an integrative framework of OE attributes; and propose future research directions for the OE literature.

To remain competitive in industry, many organizations are implementing OE initiatives. However, achieving OE in emerging markets has been a pressing challenge due to the scarce knowledge on how it works. Through a systematic review of the literature, this study aims to contribute to a deeper understanding of the concept of OE in emerging countries through the triple bottom line.

This study has found nine attributes of OE based on the three pillars of sustainability or triple bottom line (economic, environmental and social). Four of them were the most cited and served to build the proposed framework. The analysis concludes that most of the studies related to OE in emerging countries have been carried out in Asia. Finally, based on the results obtained from the literature review, six points of future research are proposed based on three research directions: OE in emerging countries, active participation by employees and culture generation and finally, research methods.

The gap that is filled in this study is that some authors have studied the application of OE in emerging countries, specifically on the Asian continent. In those cases, the literature is either oriented to describing OE from different perspectives or to its application in different companies, some of which are emerging countries. However, to the best of the authors’ knowledge, there is no study that describes the specific and complete aspects that make up a model of OE and which can show how this model can be applied in emerging countries.

Green Lean tools are aligned with the Circular Economy strategy as they aim at reducing waste, however, they miss the creation of value through waste. Therefore, this paper investigates whether the current implementation of the Green Lean strategy promotes the introduction of the Circular philosophy to achieve sustainable management production processes. It analyses how the resources were managed by implementing the different strategies and tools presented in Green Lean case studies under the lens of Circular Economy and highlights future research paths on the Circular Lean integration.

An analysis of the implementation of Green Lean case studies, selected through a Systematic Literature Review, from the manufacturing sector is conducted.

The majority of Green Lean implementations were aimed at minimizing waste, which is aligned with the narrowing strategy of Circular Economy and only a few cases studies aimed at closing the production cycles. Even though the main results indicate that being eco-efficient is a good starting point to move towards sustainability, from a Circular Economy point of view, this approach could remain limited. Therefore, the current contribution of Green Lean to the implementation of circular practices is limited. It can be concluded that introducing the circular philosophy in the Green Lean methodology can be achieved through redirecting Green Lean from waste reduction towards a value creation focus.

The originality of this paper is that it provides a critical review of the literature on the topic of Green Lean integration and Circular Economy.

This paper aims to identify key middle manager trustworthy behaviours that encourage employees’ participation in continuous improvement activities in industrial contexts.

The list of behaviours has been developed in two different phases. First, the authors conducted two concept mappings with operators and middle managers and, subsequently, the authors combined and integrated both points of view. Second, the authors developed an expert panel with researchers, consultants and experienced practitioners of industrial management for debugging and reducing the results, presenting the final list of behaviours.

This work presents 55 different middle manager trustworthy behaviours divided into four different categories: human qualities; training and development; technical and managerial competencies; and team building.

This paper contributes to existing literature about sustainable continuous improvement systems highlighting the role of middle managers and proposes a set of specific middle manager trustworthy behaviours for increasing supervisors’ influence on operator participation.

After extracting the knowledge of different stakeholders, the list of behaviours identified can serve as a useful tool for recruiting, training, evaluating and developing a supervisors’ managerial style that enhances operator participation in continuous improvement activities.
