In this current research, various amino acids (lysine, betaine, and cysteine) peptides (oxidised or reduced glutathione) were considered as potential environmentally friendly alternatives to wool bleaching. A greener methodology was also applied dyeing. Different agro-wastes (red cabbage, peppercorns, red yellow onion peels) served raw pigment materials. The process’s efficiency characterised by the whiteness degree, colour strength, fastness accelerated washing perspiration. higher index value observed in cysteine-based formulations. peel exhibited significant tinctorial properties due presence of some natural mordants. All proposed treatments designed with a primary focus on environmental sustainability. These offer sustainable alternative traditional bleaching dyeing methods for wool. They reduce costs energy consumption while creating added valorising waste.
