A circular economy (CE) transforms the linear system into a resource flow model based on reusing products and materials and increasing lifetime periods. This academic work aims to review the current CE research status from business, economic, and managerial (BEM) research perspectives. We carried out a systematic and bibliometric analysis to gather information on the current state of the art applications and learn about the leading research topics and sources. To reach these goals, we reviewed 962 research papers published in journals indexed on the Web of Science. After analysing the articles, three categories emerged worldwide: literature reviews, case studies, and frameworks and guidelines based on the current closed-loop system approach. Results evidence that BEM research in the CE is focused on the existing barriers to adopting a CE. More concretely, findings show that CEs are being slowed by the fact that citizens and companies do not know how to be circular. At the same time, the article showcases how the BEM areas and the recurring topics in CE research are increasingly being developed by collaborations between engineers and economists to design and create robust and measurable closed-loop models.

Airlines' negative impacts are rising due to the growth of the industry, and therefore new and more sustainable alternative business models are being developed and implemented. In this context, this paper analyses how airlines are incorporating Circular Economy (CE) into their service model and proposes a framework to identify the main practices of CE that support waste management. After a detailed review of the corporate social responsibility (CSR) reports of a worldwide sample of companies, this paper builds on waste and material management, where airline activities have more impacts on edible and inedible waste. Results show that companies are adopting measures such as recycling in‐cabin waste, incorporating new materials, and defining new systems to make the feeding services more efficient. Nevertheless, CE adoption is still low, and the CE strategies do not seem to follow specific patterns.

Companies have highly adopted sustainability reporting practices. Nonetheless, there are still some important research gaps related to the contents that sustainability reports should include and the appropriate frameworks to define them. This research contributes to the study of sustainability reporting practices of companies from a sectorial perspective, and it is focused on applying the materiality principle. It combines a qualitative and a quantitative approach to assess the materiality and the quality of GRI reports among sustainability dimensions and companies within an industry. To this end, an innovative research method based on scores is proposed and applied to a sample of companies in the telecommunications industry. The results indicate that while the GRI sustainability issues declared as material are more likely to be reported, there are still incoherencies in using materiality analysis as a threshold for reporting. Furthermore, there is no evidence that the materiality or quality of the reports differs among companies or sustainability dimensions. The findings suggest that materiality analysis, as companies present it, may lead to incoherencies in treating GRI aspects and indicators.
