| Abstract | In response to the growing awareness of environmental preservation, there has been a surge in studies employing the life cycle assessment (LCA) approach which helps to identify and minimize environmental impacts associated with rice straw recovery processes. However, there is lack of comprehensive and trend analysis related to the development of critical methodological steps of LCA within this field. To fill the gap, this review examines 43 primary LCA studies from 2004 to 2023 period concerning the use of rice straw for bioenergy production and categorized into two groups: the "first-year group" covering 2004-2013 and the "second-year group" spanning from 2014 to 2023. This categorization serves to facilitate the examination of trends and patterns within each decade, offering insights into the evolution of research objectives, methodological advancements, and changes in research outcomes over time. The analysis reveals a shift from studying individual technologies to comparing various technologies, includes scenarios development and consideration of economic and social aspects. Furthermore, the "second-year group" (2014-2023) exhibits a notable uptick in the exploration of gasification, pyrolysis, anaerobic digestion, and fermentation, whereas combustion technologies have experienced a slight decrease in the number of studies. Challenges in LCA studies arise from nonstandardized methodologies, introducing bias and uncertainty. To enhance the reliability and comparability of environmental assessments, it is recommended to establish standardized guidelines, improve transparency, and update databases. Overall, this review provides a foundational resource for future waste-to-energy studies and recommends steps to enhance the applicability and validity of LCA in forthcoming research.
