This paper aims to enhance the previous studies by incorporating new findings and presenting a more thorough literature overview of post-consumer waste recycling in the textile and apparel industry. The main aim of this study is to comprehensively investigate the research on post-consumer waste recycling, using an integrated approach of systematic literature assessment and bibliometric analysis of 239 research papers. This work addresses the current research prospects and challenges, detailing the interrelations among the prominent themes within each category and clarifying how each category impacts the others, to provide a thorough understanding of post-consumer textile research. Our work indicated areas for additional investigation and illustrated how bibliometric analysis and systematic literature reviews might be used to enhance comprehension of intricate research domains.
