ABSTRACT
Textile processing industries have a strong environmental effect because most of the existing activities are unsustainable, and all stakeholders are looking at the solution to reduce the carbon footprint of textiles. To make textile processing greener, many eco-friendly steps have been taken. These consist of the replacement of harmful chemicals with their eco-friendly substitutes, use of greener pre-treatment chemicals, green dyes and textile auxiliaries along with greener solvents, optimised and efficient processing, bio-processing, recycling of textiles, water and chemicals. The chapter discusses the need of recycling and reuse of valuable textile materials and the effect of harmful chemicals on the environment and human beings, besides the replacement of PCB, HCHO, heavy metals and banned amines used in textile and garment processing. In order to make the processes more sustainable, the use of best available techniques (BAT) in the recycling of dyes and chemicals, such as the standing bath technique of dye bath replenishment, salt-free dyeing, utilisation of spent dyes, and supercritical CO2 is also highlighted.
