Towards a resource friendly circular cotton processing
One of the main concerns in the textile cotton industry is the substantial amount of contaminated effluent generated from various stages, including desizing and pre-wash. The wastewater, rich in carbohydrates from starch hydrolysis, presents a promising feedstock for hydrogen peroxide (H2O2) product...
