Dyes From Discard: Upcycling Tea Waste For Sustainable Fabric Dying promotes circular resource use in the textile industry by exploring sustainable textile colouration through the innovative use of tea waste. While natural dyes currently account for only 5% of the global market due to challenges like cost, availability, and reproducibility, this work demonstrates how these limitations have inspired impactful research and practical solutions.
The book begins by reviewing synthetic dyes, their environmental impact, and modern dyeing technologies, highlighting the need for sustainable alternatives. It then delves into natural dyes—their types, sources, advances, and challenges—and examines the role of bio-based textiles and green chemistry. The focus then shifts to practical applications, presenting detailed methods for extracting dyes from black, oolong, white, and green tea leaves and transforming tea waste into effective fabric dyes.
Finally, the book showcases a success story of scaling this innovation from laboratory research to pilot trials and industrial production, using tea waste from a major ready-to-drink tea manufacturer. This real-world example demonstrates both technical feasibility and commercial potential, offering a roadmap for researchers, students, textile professionals, and sustainability practitioners.
