Bio-Dyes

The textile industry is one of the largest consumers of synthetic dyes, but their widespread use has raised serious concerns about environmental pollution, human health risks, and the depletion of non-renewable resources. Conventional dyes often rely on petrochemical derivatives and release toxic effluents during production and application.
Agroforestry waste, which includes residues such as bark, leaves, fruit peels, nut shells, and crop by-products, represents a largely untapped reservoir of bioactive compounds with inherent dyeing properties. Harnessing these materials for the production of textile bio-dyes offers a dual advantage: mitigating agricultural waste disposal challenges while generating value-added products for the textile industry. Moreover, bio-dyes derived from agroforestry waste can reduce dependence on synthetic chemicals, lower carbon footprints, and appeal to environmentally conscious consumers.
