Biotechnological advancements and challenges in textile effluents management for a sustainable bioeconomy: Indian case studies

Abstract

The textile industries role on imminent hazardous environmental impact has global attention. The remediation of textile effluent is often challenging because of the presence of a wide variety of pollutants like dyes, acids, bases, metal salts, and microorganisms. The use of biological recycling methods are contemplated to mitigate the hazardous pollutants from textile effluent to reduce environmental pollution, threatening the sustainability of living organisms. This review aims to furnish an insight into the recent advancements and challenges in biotechnological processes focusing on economic and cutting-edge technologies in the treatment of textile effluents. Recent trends using integrated biotechnological approaches and bioprocess engineering represent strategic opportunities for economic textile effluent management. Studies on advanced in-silico and multiomics (proteomics, genomics, metabolomics) approaches have been highlighted. This review also identifies the gaps and issues in effluent treatment operations. Several case studies on waste effluent treatment and recycling practices in India are also reported. Important legislation and laws for regulating and controlling textile waste effluent are also described.
