"Biogenic colourants in the textile industry - a promising and sustainable alternative to synthetic dyes";
Green Chemistry, 24 (2022), 13-35; 23 pages.



English abstract:
The textile and dyeing industry has shown dramatic growth alongside synthetic chemistry in the last century. With increased operations and economic importance, challenges also emerged, including environmental
pollution, work safety, and consumer health. Hence, a change of perspectives in the industry is on the rise,and environmentally-friendly solutions for safer processes and more circularity are urgently sought-after. A possible solution for the pressing issue of textile dyeing is found in the use of natural colourants obtained in
fermentation processes. The structural diversity of biogenic dyes is potentially high enough to pose an alternative on a broad front. Matching fundamental properties concerning dyeing, (bio)synthesis and toxicity give an impression of the advantages of developing this natural alternative. In this contribution, a comparison between biologically-derived dyes and their synthetic counterparts is conducted on several levels. The most important topics for the future are outlined. Significant challenges and potential solutions that limit the implementation of biogenic dyes into the textile dyeing value chain are discussed. Biotechnology offers numerous methods to increase reliable production or engineer molecular properties elegantly. The biggest advantage from a Green Chemistry perspective is the possibility to switch to renewable starting materials
and obtain more biodegradable dyes. A more sustainable alternative in textile dyeing is afoot. It needs to be embraced and developed to provide the world population with a sustainable way into the future.
