Within this cluster, there are 34 articles dedicated to exploring the impediments, obstacles, prospects, and catalysts associated with the adoption of CE practices. Recognizing the essence of CE, its environmental implications, business implications, and its relevance for our future is undoubtedly vital [
57]. Yet, it’s equally imperative to comprehend the factors that either facilitate or hinder businesses in their pursuit of CE objectives. Also, comprehending not just what CE entails but also what aids or obstructs businesses on their journey towards CE is as crucial as understanding the significance of CE itself. [
58] investigated the co-evolution of “lean and green thinking,” as well as the potential for lean and green practices to enable successful transitions to sustainable business practices in Australia. [
58] study identifies three pivotal drivers and six significant barriers crucial to the transformation of SMEs. Among these three drivers, “Coercive drivers” appear to be the most influential factor observed among SMEs, potentially attributed to the stringent environmental regulations prevalent in Australia. The SMEs under examination also adopt coercive isomorphic drivers, which involve pressures exerted by influential entities, including other organizations they depend on, and are influenced by ethical and societal expectations. In a broader context, industrial practitioners report experiencing positive reinforcement from their combined lean and green operations, aligning with their aspirations for sustainable business practices. The study distinctly showcases the integration of lean and green strategies rather than their separate implementation. However, the research also uncovers six key obstacles to sustainable business practices, encompassing challenges such as “limited financial resources,” “time constraints,” “knowledge gaps,” “risks associated with adopting new sustainable practices,” “current regulatory policies,” and the influence of existing organizational culture. We concluded from our research, according to [
58] the four key enablers for CE transformation can be named: Aligning the organizational strategic objectives with CE strategies, reinforcing synergistic results by continuous improvement using lean and green methods, involving internal and external stakeholders to optimize the organization’s processes, and finally, streamlining processes to ensure transparency and traceability will enable SMEs to achieve sustainable business practices. [
59] in their research provided an overview of barriers that restrained the adoption of CBMs, this research indicates that most of the barriers that companies encountered with are at the organizational level. Additionally, [
60] investigate the critical success factors for sustainability and CE in the beverage industry which indicates that collaboration, continual innovation, and a solid foundation can be the first steps to adopt CE practices. On the other hand, barriers included external events and lack of support. Based on our research, we have arrived at the conclusion that in addition to the previously mentioned barriers, we can also assert political barriers, lack of consumer awareness [
61], lack of financial resources, lack of technical expertise [
62], lack of supply chain design and optimization [
63], cultural and customer’s beliefs [
64], lack of strong and committed management [
65,
66], and regulatory frameworks and policies that either lack the support for CBMs or impede their successful implementation [
62], resistance to change, quality of the finished product and associated risks [
48] stands out as prominent barriers that organizations encounter when adopting and transitioning to a new CBM. These factors collectively represent a substantial part of the top barriers and challenges that organizations face in their transformation processes [
67]. To address these challenges, companies and organizations can employ drivers to ease their transformation. According to [
68] involvement of different stakeholders plays an important role in CE transformation. Education and cultural change can facilitate the transformation process [
69]. Of course, having a clear business model and financial plan can help during the transition [
62] but an organization should not underestimate the power of collaboration among different consumers, suppliers, and partners which would greatly benefit the CE transformation [
70]. The result of our research shows that the top management commitment is the key enabler for initiating and designing the best possible organizational structure and organizational culture which can lead to effective CE implementation. Globalization and environmental policy are the other two key enablers that have a direct impact on the long-term strategic planning toward CE implementation [
71]. The risks linked to adopting CE practices pose a significant obstacle to achieving CE transformation [
46]. For example, CE necessitates established companies to overhaul both their supply chains and business models to adopt a more sustainable and circular approach. However, the challenges encountered by these established companies in reconfiguring their business models elevate the risk of potential setbacks in the future. Consequently, newly launched firms might possess a greater capacity for disruption and the redesigning of value chains, potentially positioning them as more agile and adaptable players in the evolving landscape of CE practices [
61]. So, it becomes essential to develop a risk management tool that helps the organizations in navigating these uncertainties, facilitating the transition towards a CBM. This tool serves to enhance managers’ comprehension of the specific CE changes feasible within their organizations. Additionally, it provides valuable insights into the various activities, procedural steps, and anticipated outcomes associated with this transformative process. [
46]. In assessing a company’s capacity to implement CE strategies, it is essential to consider not only the external drivers and barriers but also internal factors that can either enable or hinder CE initiatives. According to one of the articles that comprehensively investigated these kinds of drivers and barriers, we can mention that profitability, reduction of costs, resources efficiency, sustainable business and growth, and environmental safety can be addressed as internal drivers for organizations to move toward CE strategies and business models [
72]. Furthermore, it is crucial for companies to gain a comprehensive understanding of their opportunities and capabilities in terms of “sensing,” “seizing,” and “reconfiguring” the factors driving CE adoption. These capabilities, often referred to as the dynamic capabilities of the company, can serve as a potent enabler for achieving their sustainability objectives [
21,
48]. For such reasons, according to [
21] study, the ability of established companies to adopt CE practices is influenced by their reliance on current product offerings and a business model centered around products and supply chain positioning. These factors can limit changes in areas such as product categories, target customers, pricing strategies, and brand identity, potentially hindering progress toward environmentally sustainable goals. The study emphasizes the importance of dynamic capabilities for firms to overcome these path-dependent limitations and successfully transition to CBMs. Even though some practitioners pinpoint the importance of dynamic capabilities to facilitate the CE transformation processes in companies [
48,
49,
73], yet there is limited research to fully understand the practical application of dynamic capabilities in transition processes and there is need to investigate this topic in more details [
74].
