Research into plastic recycling is rapidly increasing as ocean and land pollution and ecosystem degradation from plastic waste is becoming a serious concern. In this study, we conducted a systematic review on emerging research topics, which were selected from 35,519 studies on plastic recycling by bibliometrics analysis. Our results show that research on the biodegradability of plastics, bioplastics, life cycle assessment, recycling of electrical and electronic equipment waste, and the use of recycled plastics in construction has increased rapidly in recent years, particularly since 2016. Especially, biodegradability is the most emerging topic with the average year of publication being 2018. Our key finding is that many research area is led by developed countries, while the use of recycled plastics in the construction sector is being actively explored in developing countries. Based on our results, we discuss two types of recycling systems: responsible recycling in the country where plastic waste is generated and promoting recycling through the international division of labor between developed and developing countries. We discuss the advantages and disadvantages of both approaches and propose necessary measures for sustainable and responsible production and consumption of plastics such as waste traceability system and technology transfer between developed and developing countries.
PurposeThis study investigates competitive intelligence (CI)-related practices in companies, including process, scope and organizational structure. As these aspects have not been sufficiently discussed in the literature, the study objective is to determine (1) the type of CI process being employed, (2) whether the CI scope is limited to competitor analysis or spans a broader business environment and (3) whether the CI process and scope vary depending on organizational CI.Design/methodology/approachAn interview was conducted at two types of Japanese companies: one established a CI department to implement CI, whereas the other did not establish a CI department and conducted CI in an ad hoc manner. Multicase studies were performed to examine companies with different organizational structures.FindingsThe CI scopes included a broad range of factors (e.g. technology, customers, markets, suppliers, economy, society, politics, legislation and regulation), and not only competitor analysis. An established CI department did not guarantee a well-organized CI process. Furthermore, the lack of such a department did not preclude systematic CI processes or activities.Originality/valueThe authors classified the CI in the companies the authors inspected as either systematic (organized CI) or ad hoc (unorganized CI) methods. The advantages and disadvantages of both are discussed. The authors found the promotion mechanisms in company-wide CI process, which can cause intelligence transfers from CI to absorptive capacity processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
