Textile industries are the second most polluting industry in the world in terms of producing solid and liquid wastes. The preparatory processes as well as the dying, printing, and finishing processes of fabric produce a huge amount of liquid waste. The waste generated from these processes contains synthetic dyes, strong acids, alkalis, peroxides, formaldehyde, chlorinated compounds, and their derivatives. These adversely affect the environment due to their carcinogenic and mutagenic nature, which also causes bioaccumulation and biomagnification. Due to the fast fashion trend, the life span of clothing is being reduced. The solid wastes in terms of fabric cut pieces and discarded cloth end up in landfills, which contributes to non-biodegradable solid waste because of the presence of synthetic fibres like polyester, nylon, polypropylene, etc. These solid wastes can be managed through the recovery, recycling, and reuse methods; in some cases, can replace the primary resources with secondary resources. Considering the ecological harm, the implementation of technologies like electrocoagulation, flocculation, floating treatment wetlands system (FTWs), advanced oxidation process (AOP), membrane filtration technology, nanotechnology, ozonation, biological methods for wastewater treatments have shown significant results. Biological methods such as sequential degradation, and aerobic, anaerobic, and anoxic treatment are taken into account for sustainable development. However, it is difficult to choose particular processes since the textile sector might utilize a variety of chemicals and raw materials. This chapter summarises the risk factors associated with the textile industry and the recent development of their mitigation strategies for the probable reuse of solid and wet wastes. Future scopes, integrating multiple methods including green technologies for mitigation of hazards have also been elucidated.
