The bibliometric method was used in this study to analyze current advances in the anaerobic digestion (AD) of cellulose waste. The result shows that the number of articles increased rapidly after 2010, suggesting a growing interest in this field. The USA and China were the top two countries with the highest number of published articles. AD of cellulose waste is being actively explored in many countries, and partnerships between countries are being actively formed. The top three subject categories were Environmental Sciences & Ecology, Engineering, Energy & Fuels. The most widely published and influential journals were Bioresource Technology, Water Science and Technology, and Waste Management. The co-occurrence and trend analysis of author keywords indicates that current research is primarily focused on pretreatment and co-digestion. Microbial community analysis plays a crucial role in elucidating the mechanisms, and life cycle analysis (LCA) could evaluate the impact on the environment at different stages. Microbial community analysis and LCA will be the hotspots in the future. To some extent, this study helps to understand the current global status and trends of the related research.

In an era marked by rapid technological advancements and the pervasive presence of the electronics industry, electronic waste (E-waste) has become a prominent global concern. This study utilizes a rigorous bibliometric analysis to thoroughly investigate the extensive body of literature in this field, shedding light on the current state of research and development in E-waste recycling. The study dissects and visualizes research trends, trajectories, and advancements. It meticulously examines a dataset comprising 3267 records extracted from the Web of Science Core Collection, specifically the Science Citation Index Expanded. The analysis highlights China’s pivotal role in E-waste recycling research, contributing 41% of the total research papers in this field. Additionally, the British journal ‘Waste Management’ emerges as a standout among academic publications, with an impressive count of 241 articles, constituting 7.38% of the entire corpus. Notably, Zeng, X.L., emerges as the most co-cited author, underscoring their significant influence and contributions to the scholarly discourse. Tracing the evolution of E-waste recycling research from 1990 to 2022, the study uncovers the field’s inception in 1993 when the first research paper on this subject was published. This nascent domain has since experienced exponential growth, culminating in an impressive 408 papers published in 2022. The research identifies and distills three compelling research trends that have captured significant attention within the E-waste recycling domain. Firstly, it highlights the paramount concern regarding the environmental impact of organic pollutants from E-waste, emphasizing the urgent need for sustainable solutions. Secondly, it delves into the intricate issue of managing and recycling E-waste in developing countries, where unique challenges necessitate innovative approaches. Lastly, the analysis underscores the growing interest in recovering and recycling materials from discarded electronic devices, highlighting the imperative necessity of harnessing the valuable resources within E-waste. In synthesis, this research not only provides an overview of the current landscape of E-waste recycling but also offers a clear path forward for future studies and interventions. It serves as a critical guide for addressing the environmental and socio-economic repercussions of E-waste, ultimately fostering a more sustainable and economically viable future.

This paper aims to understand the status of the Chinese National Standards on Packaging and the Environment (CNSPE), analyze the existing problems, and discover their possible solutions. Based on the standard bibliometric literature, the metadata information from the CNSPE have been collected and analyzed. The results indicated that the number of CNSPE released showed a wave-like growth with two peaks during 2006–2010 and 2016–2020 driven by both external and internal factors. The basic standard was the main standard sort. The average valid period of a CNSPE was 5.90 years, while the update rate was 23.33%. Public institutions lead the drafting committee of the CNSPE. The percentage of adopting the international or foreign standards was 28.86%, and the average conversion time was 7.61 years. There were four problems deduced from the results, including the unbalanced supply of different sorts of CNSPE, long valid period of standards with low update rates, low engagement of the enterprises, and loose links between national standards and international standards. The corresponding solutions are (1) strengthening market research and combining with policy development to optimize the supply of different sorts of CNSPE; (2) improving the process management ability of standardization organizations to enhance the supervision and feedback of standards development and implementation; (3) providing trainings and broadening dissemination while fulfilling the reward mechanism; and (4) enhancing the compatibility between the national standards system and the international standards system to promote the standard internationalization level.
