description The conversion of textile water sludge (TWS) into solid recovered fuel (SRF) represents a promising approach to addressing environmental challenges, advancing waste-to-energy strategies, and promoting circular economy principles. This manuscript explores Taiwan’s innovative efforts in SRF production from textile industry waste, highlighting its integration into industrial processes, regulatory frameworks, and global relevance. The study examines the key technological processes involved, including sorting, drying, and torrefaction, which enhance fuel properties such as calorific value and combustion efficiency. Challenges related to raw material availability, quality control, economic viability, and public perception are analyzed alongside potential solutions such as advanced processing technologies, government incentives, and industry collaboration. Comparisons with international practices reveal Taiwan’s leadership in leveraging textile water sludge as a feedstock while identifying opportunities for further alignment with global standards and scalability. The environmental benefits of SRF, including waste reduction and greenhouse gas mitigation, are juxtaposed with risks like emissions control and high production costs. This comprehensive review underscores the potential of SRF production from textile water sludge as a sustainable solution for waste management and energy generation, contributing to Taiwan’s net-zero emissions goals and offering valuable insights for global adoption.
