Abstract

Pyrolysis technology holds great potential for sustainable sewage sludge treatment due to its ability to recover energy, tackle the environmental challenges, and convert by-products into valuable resources. However, a comprehensive understanding of its research progression, sustainability implications, and policy relevance remains limited. This study offers a comprehensive analysis of sewage sludge (SS) pyrolysis research, integrating sustainability through life cycle assessment (LCA) and circular economy principles. Using Scopus and VOSviewer, it highlights significant growth in research, with publications rising in this decade, reflecting increasing global interest driven by environmental and technological imperatives. China dominates the field with 693 publications and extensive international collaborations, followed by the United States and Australia. Key journals play pivotal roles in disseminating findings, while interdisciplinary contributions span environmental science, energy, and chemical engineering. Keyword analysis reveals emerging trends such as circular economy, LCA, and carbon sequestration highlighting a growing focus on sustainable practices. LCA studies show that advanced pyrolysis technologies reduce greenhouse gas emissions, and align with United Nations Sustainable Development Goals. Circular economy analyses underscore the economic viability of co-pyrolysis, alongside substantial energy recovery and bio-oil market potential. Additionally, this study explores the key technological challenges and mitigation strategies crucial for optimizing SS pyrolysis systems and advancing future research. These findings underscore the adaptability of SS pyrolysis for waste valorization and its role in addressing environmental challenges. This analysis provides valuable insights for advancing research, informing policy, and optimizing industrial practices, highlighting SS pyrolysis as a critical technology for sustainable waste management and resource recovery.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
