Increasing regulatory obligations to adapt and execute environmentally friendly operations make it critical for businesses to pursue strategies that can strengthen their competitive edge in the market. Academics and practitioners alike have recently gravitated toward exploring how knowledge acquisition activities might improve business outcomes. To address this growing research interest, this study investigates the critical roles of green knowledge acquisition in enhancing green knowledge management and green technology innovation activities in improving corporate environmental performance, positioning resource commitment as a moderator. The research model has been assessed using structural equation modeling with survey data from 283 Indian manufacturers, demonstrating that green knowledge acquisition significantly impacts green knowledge management and green technology innovation. The statistical findings also show that green technology innovation acts catalyzes the translation of green knowledge management into improved corporate environmental performance. The results demonstrate that resource commitment moderates green knowledge acquisition's interaction with green knowledge management and green technology innovation, providing practical insights enabling managers to focus on planning, allocating, and budgeting resources for effective green practices that can contribute to improving corporate environmental performance.

Purpose: Most companies include a commitment for sustainable growth involving a switch towards the circular economy (CE) model. The purpose of this paper is to present barriers to CE adoption identified by a literature review. The paper also addresses the particular challenges faced by manufacturers by answering the research question: What are the dominant barriers faced by the manufacturing industry in moving towards a CE?Design/methodology/approach: This paper presents a literature review of research identifying barriers for adopting to CE in the manufacturing sector. The literature review is followed by a case study identifying barriers to CE as seen by ten companies within manufacturing, including the GS1 global information standardisation agency used by all manufacturers.Findings: The manufacturers investigated focus mostly on recycling and waste reduction. These policies have low or very low CE effect. High CE effect policies like maintenance and reuse targeting the CE ideal of no waste, are nearly non-existent. The results identified seven main barriers to the CE: (1) high start-up costs, (2) complex supply chains, (3) challenging business-to-business (B2B) cooperation, (4) lack of information on product design and production, (5) lack of technical skills, (6) quality compromise and (7) disassembly of products is time-consuming and expensive.Research limitations/implications: The data come from participants in a single country, Norway, although the manufacturers are multinational companies adhering to enterprise policies.Practical implications: This research shows that all the companies interviewed are well aware of the growing need for their company to move towards more sustainable operations involving CE concepts. The barriers identified are explored, and the findings could guide such companies in their efforts to move to maintenance, reuse, remanufacture and recycle (M+3R) operational model.Social implications: The study has found that the major barriers for implementation of CE are quality issues in recycled materials, supply chain complexities, coordination problems between companies, design and production of the product, disassembly of products and high start-up/ investment costs.Originality/value: The research shows how the transition towards a CE takes place in manufacturing industries by studying the manufacturing sector.

Research on sustainable development is significantly influenced by the trade‐off between the economic, social and environmental performance of businesses. Industry 4.0 development is a key business priority due to the promise of exponential increase in productivity, time efficiencies and cost reduction. However, Industry 4.0 development has been slow. Notably, human actors remain central to Industry 4.0, while the social responsibility component of sustainable development is a key prerogative for industry, championed through the UN sustainable development goals and European Commission. Therefore, we evaluate human‐related impediments for Industry 4.0 and critically explore how human resource management (HRM) can overcome these barriers using a socially responsible orientation. First, we analyse the human‐related challenges to Industry 4.0 through a thematic literature review. Thereafter, through an integrative literature review of different research streams (Industry 4.0, HRM and social responsibility), we critically argue novel perspectives on how human resource practices can enable sustainable development of Industry 4.0 in a socially responsible manner. Herein, we address a crucial literature gap. Our findings reveal numerous people‐related barriers, including change resistance, digital skills gap, employment threats widening socio‐economic inequalities, lack of industry‐wide collaboration, leadership and organisational culture challenges. We show that HRM can be a crucial enabler for sustainable Industry 4.0 development through socially responsible human resource practices. These include strategic multistakeholder collaborations, holistic talent management, change leadership, inclusive knowledge sharing, sponsoring education research and codesigning curricula, smart technology for upskilling and retention and rewarding inclusive Industry 4.0 ideas. We conclude with future research directions.

Purpose: This study aims to conduct a comprehensive review and network-based analysis by exploring future research directions in the nexus of circular economy (CE) and sustainable business performance (SBP) in the context of digitalization.Design/methodology/approach: A systematic literature review methodology was adopted to present the review in the field of CE and SBP in the era of digitalization. WOS and SCOPUS databases were considered in the study to identify and select the articles. The bibliometric study was carried out to analyze the significant contributions made by authors, various journal sources, countries and different universities in the field of CE and SBP in the era of digitalization. Further, network analysis is carried out to analyze the collaboration among authors from different countries.Findings: The study revealed that digitalization could be a great help in developing sustainable circular products. Moreover, the customers' involvement is necessary for creating innovative sustainable circular products using digitalization. A move toward the product-service system was suggested to accelerate the transformation toward CE and digitalization.Originality/value: The paper discusses digitalization and CE practices' adoption to enhance the SP of the firms. This work's unique contribution is the systematic literature analysis and bibliometric study to explore future research directions in the nexus of CE and SP in the context of digitalization. The present study has been one of the first efforts to examine the literature of CE and SBP integration from a digitalization perspective along with bibliometric analysis.

Purpose: The academic literature and research lines exploring the effect of quality improvement methods on environmental performance still remain in early stages. The purpose of this paper is therefore to investigate, through a systematic review of the existing academic literature, the environmental (green) impact of using quality and operations improvement methods such as Lean, Six Sigma and Lean Six Sigma. This includes the impact on energy saving and the usage of natural resources.Design/methodology/approach: This study follows a systematic literature review approach through which it analyses research papers published in top 16 operations and quality management journals. No specific time frame was established, but a set of keywords were used to short-list the articles. A sample of 70 articles was finally short-listed and analysed to provide a discussion on environmental concerns related to Lean, Six Sigma and Lean Six Sigma.Findings: The comprehensive review of short-listed articles indicates that both Lean and Six Sigma can be considered effective methods to support the conservation of resources, combat global warming and saving energy. Various scholars provide evidence of this, and as such, organisations should not only consider these methods to manage quality and improve operational performance but also meet environmental regulations. A set of research questions that demands further investigation has also been proposed based on the findings of this research.Research limitations/implications: This study is limited to a sample of 70 articles collected from top 16 operations and quality management journals. The search of journals is also limited to a set of key words (“Lean”, “Green”, “Six Sigma”, “environment”, “sustainable” and “sustainability”) used to short-list the sample size.Practical implications: The study shows that organisations can consider the adoption of Lean, Six Sigma and Lean Six Sigma to meet environmental regulations, save costs and also meet quality management standards. This will contribute in helping organisations to formulate more effective and inclusive strategies which do not only consider the quality and operational dimensions but also the environmental dimension.Originality/value: Literature exploring the environmental/green impact of quality management methods commonly used in industry is limited. There is also a lack of studies aiming to investigate the green impact of Lean and Six Sigma in top operations and quality management journals. The study focusing on investigating the green impact of Lean, Six Sigma and Lean Six Sigma methods altogether is also a research first of its kind.
